You’ve seen adverts for casino sites, and you’re wondering how they actually work. Is a digital slot fair? What does “96% RTP” mean? Is a bonus really free money?

These are sensible questions to ask before you deposit. Online casino games are designed so that, over time, the casino keeps a share of what is staked. If you understand how big that share is, you can choose games and sites that fit your budget, and you are less likely to be surprised by a quick loss or by bonus terms. This guide explains RNG, RTP and house edge without jargon, works through what games and bonuses really cost, and shows how to choose a casino site by your play style, with six licensed examples and the safer gambling tools to switch on first.

Gambling is entertainment that you pay for, not a way to make money. Keep that in mind as you read.

What are casino sites? The short answer

A casino site is a website or app where adults can play casino games, such as slots, roulette and blackjack, for real money. In Great Britain, a casino site that takes British players must hold a remote casino licence from the Gambling Commission.

What you actually do on a casino site

You open an account, prove your age and identity, add money and choose a game. Each bet is taken from your balance. Any winnings are added back, and you can ask to withdraw your balance to your bank or payment method.

Licensed sites must check your age and identity before you can deposit or play, including free-to-play versions of their games (a rule since 7 May 2019). A site may first match your name, address and date of birth electronically against records such as credit reference agencies and the electoral roll, which can be instant. If that doesn’t confirm you, it can ask for documents such as a passport, driving licence or household bill, which takes longer. Finishing these checks at sign-up avoids delays when you withdraw.

Who makes the games and who runs the site

Two kinds of company are usually involved:

• Game studios design the slots and table games. A studio usually supplies its games to many different sites, so you’ll often see the same slot at several casinos.
• The operator runs the site. It holds the licence, looks after your money, sets the bonus terms and handles withdrawals and complaints.

One operator can run several brands under one licence. For example, LeoVegas Gaming PLC (account 39198) lists BetMGM, LeoVegas and several other brands on the Gambling Commission register. This matters when you set limits or take a break, because some tools cover every brand on the licence, not just the one you signed up to (see “Limits and time-outs” below).

Why a Gambling Commission licence matters

The licence is what gives you protection. Licensed operators must follow rules on fair games, age checks, advertising, bonus terms and safer gambling tools. They must also offer an independent dispute service if you can’t settle a complaint with them.

Every licensed site shows its Gambling Commission account number, usually in the footer. You can type that number into the Gambling Commission public register and see the company name, its licences and the web addresses it is allowed to use.

What a casino site is not

A casino site is not an investment, a side income or a way to solve money problems. The games are built so that players as a group lose money over time. Some sessions end in profit, but that is chance, not a skill you can rely on.

Sites that advertise themselves as “not on GAMSTOP” or “no verification” are not licensed in Great Britain. You have far fewer protections there, so this guide doesn’t cover them.

How casino sites work: RNG, RTP and house edge in plain English

Three ideas explain almost everything about casino games: RNG decides each result, RTP tells you the long-run average paid back, and the house edge is the share the casino keeps. Here’s each one in plain English.

RNG: how a digital game picks a result

RNG (random number generator) is software that produces unpredictable numbers. A digital slot or roulette game turns those numbers into a result, such as where the reels stop or which pocket the ball lands in.

The Gambling Commission’s technical standards say random number generation and game results must be “acceptably random”. They also ban “adaptive behaviour”, meaning a game must not change its results to make up for recent wins or losses. A slot can’t “tighten” because you’ve just won, or “loosen” because you’ve lost for a while.

Live dealer games are different. They use a real wheel, real cards and a human dealer, filmed in a studio and streamed to you.

RTP: a long-run average, not your result

RTP (return to player) is the percentage of all money staked on a game that the game is designed to pay back over a very large number of plays.

If a slot shows an RTP of 96%, the maths says that across millions of spins, it pays back about £96 for every £100 staked. It does not mean you’ll get £96 back from your £100. In one session you might lose all of it, or finish ahead. RTP describes the average across everyone and over a very long time, not what will happen to you tonight.

House edge: the other side of RTP

The house edge is the share of each stake the casino expects to keep over the long run. It is simply 100% minus the RTP.

RTP	House edge	Average cost per £1 staked
97.3%	2.7%	about 2.7p
96%	4%	4p
94.7%	5.3%	about 5.3p

The figures above are maths examples, not the RTP of any particular game.

Think of the house edge as the price of playing. A lower house edge means your money tends to last longer for the same amount of play. It doesn’t change the fact that the expected result is a loss.

Volatility: how bumpy the ride feels

Volatility (sometimes called variance) describes how results are spread out. Two slots can have the same RTP and feel very different:

• Low volatility: frequent small wins, fewer long losing runs. Your balance moves up and down gently.
• High volatility: long runs with little or nothing, broken by occasional larger wins. Your balance can drop fast.

Volatility doesn’t change the long-run cost. It changes how quickly a budget can go, and how wild the swings are. Some game studios describe a game’s volatility in its info screen; others don’t.

Who checks that the games are fair

Before a new game or RNG can go live on a licensed British site, it must be tested by an approved test house. According to the Gambling Commission’s testing strategy, testing includes:

• statistical testing of the RNG’s raw output
• checking the game’s maths, rules and theoretical RTP
• simulation testing to confirm the actual RTP is within an acceptable range of the stated RTP

The Commission says new games and RNGs can only be released once testing is complete and the report has been sent to it. The standards also say a game’s rules, payouts and probabilities may not be changed while it is available for play.

Where to find a game’s RTP and rules

The Commission’s technical standards require sites to make information about your chances easy to find for each game. That means a description of how the game works, plus either the house edge, the RTP percentage, or the probability of winning.

On most sites, you’ll find it by opening the game and tapping the “i”, “?” or “Paytable” button. Before you play a new game, look for three things: the RTP, the minimum and maximum stake, and how the bonus features work.

Four myths worth dropping

1. “This slot is due a win.” Each result is independent, and games can’t compensate for past losses.
2. “Playing at a certain time pays better.” Nothing in the RTP or rules changes by time of day while a game is live.
3. “I can spot a pattern.” RNG output is tested to be acceptably random. Patterns you notice are coincidence.
4. “Higher stakes improve my odds.” A bigger stake doesn’t change how the RNG picks results. You just win or lose money faster.

Summary: RNG decides each result at random. RTP is the long-run share paid back, and the house edge is the share the casino keeps. Volatility changes how bumpy your session feels, not the long-run cost.

What casino games really cost: worked examples

The house edge is easier to understand with numbers. The examples below are worked maths, not facts about any particular game. They show averages over a very large number of plays. They are not predictions of what will happen in any one session, and none of them shows a way to come out ahead.

Each example ends with the same question answered: what should you expect to lose, and why?

Example 1: £20 on a slot

Say you bring £20 to a slot with an RTP of 96% (a 4% house edge) and bet 20p a spin. What you lose depends on when you stop:

• You stop after 100 spins. That’s £20 staked once, and the average cost is 4% of £20: 80p. That’s an average across many players. Some will be up; others will have lost most of the £20.
• You re-stake any winnings until the balance hits zero. Then you lose the full £20. The house edge only decides how long it takes: on average about £500 of stakes (£20 ÷ 4%), or around 2,500 spins. On a high-volatility slot it can go much faster.

What to expect: 80p is the cost only if you put the £20 through once and stop. Play until it’s gone and you lose all £20. Treat the £20 as the price of the session, and set your stopping point before you start.

Example 2: single-zero vs double-zero roulette

European roulette has 37 pockets (1–36 plus one zero). A single-number bet pays 35 to 1: if it wins, you get £35 in winnings plus your £1 stake back, so £36 in total. Over 37 spins, one £1 bet on the same number wins once on average. That’s £36 back for £37 staked, so £1 lost every 37 spins.

• Single zero: 1 ÷ 37 = a house edge of about 2.70%.
• Double zero (American roulette, 38 pockets): 2 ÷ 38 = a house edge of about 5.26%.

What to expect: 100 bets of £1 cost about £2.70 on average at single-zero roulette and about £5.26 at double-zero. It’s the same game, but double zero costs almost twice as much. If a site offers both, check the wheel layout in the game info.

Example 3: free spins with no wagering

Take a typical UK offer: deposit £10 and get 100 free spins at 10p each with no wagering. “No wagering” means anything you win from the spins is paid as cash you can withdraw.

• The spins: 100 × 10p = £10 of play. At a 96% RTP they pay out about £9.60 on average across all players. A few people get much more; many get less.
• Your £10 deposit: your own money, which faces the house edge like any other stake (some offers make you stake it before the spins arrive). Put through once on a 96% slot, it costs about 40p on average. Played until the balance is gone, it’s lost in full, along with anything the spins paid that you didn’t withdraw.

What to expect: treat the spins as a discount on your first session, not as income. The offer exists to get you to deposit and keep playing, and on every pound you stake yourself the expected result is a loss.

Example 4: a deposit bonus with 10x wagering

A wagering requirement (or playthrough) is how much you must bet before you can withdraw bonus money, or winnings made with it. Since 19 January 2026, the Gambling Commission has capped it at 10 times.

Say you deposit £50 and get a £50 bonus with 10x wagering on the bonus. You now have £100 to play with: £50 of your own cash and £50 of bonus money. You play a 96% RTP slot.

• You must stake 10 × £50 = £500 before the bonus can be withdrawn.
• The average cost of £500 of stakes at a 4% house edge is £20. That cost comes out of the whole £100, including your own £50.
• If losses empty your balance before you’ve staked £500, the offer ends and your £50 deposit is gone. With only £100 to cover £500 of stakes, that is a real risk, especially on a high-volatility slot.

If you stop early, what you keep depends on the site’s terms. Casumo’s terms, for example, say you can withdraw your cash balance at any time, but withdrawing before the wagering is finished forfeits the bonus and any winnings made with it. If the time limit runs out, the bonus and bonus winnings are lost.

What to expect: the £50 headline isn’t money you’ll receive. About £20 of the combined balance goes on the required play on average, and a losing run can take your whole £50 deposit before you finish.

Two conditions that both get called “wagering”. Don’t mix them up:

• A qualifying stake is play you must do to unlock an offer. BetMGM’s welcome offer, for example, asks you to deposit £10 and stake it once on casino games to get its free spins. Its terms show live casino games counting 0% towards this, so live dealer play won’t unlock the spins.
• A wagering requirement is play you must do before you can withdraw a bonus. Check what it’s multiplied by. With a £40 deposit, Casumo (50% match, 10x on the bonus) would give a £20 bonus and need £200 of stakes. Videoslots (100% match, 10x on the deposit) would give up to £40 of bonus and need £400 of stakes.

Comparing Examples 3 and 4

	No-wagering free spins (Example 3)	Deposit bonus, 10x wagering (Example 4)
Your own money in	£10	£50
Play needed before you can withdraw	None for spin winnings	£500 of stakes
Average cost of that required play	None	About £20
Is your deposit tied to the offer?	No, in this example. You don’t have to stake it to get the spins	Yes. If the balance runs out before £500 is staked, it’s gone
Rules to track	Expiry of the spins	Wagering, time limit, maximum bet, game contributions

For a beginner, the no-wagering spins are the simpler choice: a smaller deposit and nothing to unlock or forfeit. The deposit bonus’s bigger headline doesn’t make it better for you; it asks for more of your own money and more play. Taking no offer is fine too. Neither changes the fact that the expected result is a loss.

Example 5: why speed matters

The house edge is charged on every bet, so the more bets per hour, the higher the cost per hour.

The Gambling Commission bans online slot spins faster than 2.5 seconds. At that limit, you could play up to 24 spins a minute, or 1,440 an hour.

What to expect: at £1 a spin and a 4% house edge, playing at full speed costs about £57 an hour on average (1,440 × £1 × 4%). At 20p a spin it’s about £11.50. Slowing down, lowering your stake and taking breaks all cut the cost of the same time spent playing.

Summary: Your expected loss is the house edge × the total amount you stake. Lower stakes, slower play, lower-edge games and offers without wagering all reduce it. None of them turn the expected result into a profit, and if you play until your balance is gone, you lose all of it.

Casino game types on UK casino sites

Most casino sites group their games into the types below. Each one feels different and suits a different kind of player.

Online slots

Slots are the largest category on almost every casino site. You choose a stake and spin. Results come from the RNG, and the paytable shows what each symbol combination pays. Common styles include classic three-reel games, video slots with bonus rounds, and “Megaways” games where the number of ways to win changes on each spin.

UK rules for online slots:

• Maximum stake: £5 per spin if you’re 25 or over, and £2 if you’re 18–24. These limits apply to slots only.
• No spins faster than 2.5 seconds, and no autoplay.
• No “fake wins”: sounds or graphics that celebrate a return equal to or below your stake are banned.
• Sites must show your total wins or losses and time played during a slots session.

Jackpot slots

Jackpot slots add a large prize that’s won rarely. A progressive jackpot grows as people play, often across many sites. Part of each stake feeds the jackpot, so check the game info to see how the RTP is made up. Treat the jackpot as a long shot, not a target.

RNG table games: roulette, blackjack and baccarat

These are digital versions of classic casino tables, run by the RNG.

• Roulette: choose a number, colour or group. Check whether the wheel has one zero or two.
• Blackjack: you make choices (hit, stand, double), so how you play affects the house edge. The rules vary between versions, so check the game info.
• Baccarat: a simple game where you bet on the player, banker or a tie.

RNG table games let you play at your own pace, often at low minimum stakes, and the slot stake limit doesn’t apply to them.

Live dealer games

Live dealer (or live casino) games stream a real dealer, wheel or cards from a studio. You bet through your screen within a time limit, and the dealer runs the round. They’re slower and more social than RNG games. Table minimums vary; for example, Sky Vegas says its own live roulette table starts at £0.10. Live games may count little or nothing towards bonus conditions (BetMGM’s offer counts them at 0%; see Example 4).

Live game shows

Game shows are live, studio-based games with a presenter, usually built around a big wheel or bonus rounds. They’re designed as entertainment, and the RTP can differ between bets on the same show. Check each bet’s RTP in the game info.

Bingo, slingo, scratchcards and instant wins

Many casino sites also offer:

• Bingo: ticket-based rooms with set start times and a chat room.
• Slingo: a mix of slots and bingo.
• Scratchcards and instant wins: a single reveal decides the result, which makes play very fast.

Fast games run up the cost per hour quickly (see Example 5), so set a time limit.

Game types compared

Game type	How the result is decided	Pace	Your decisions matter?	Suits
Slots	RNG	Fast (min 2.5s a spin)	No	Short, simple sessions
Jackpot slots	RNG	Fast	No	Long-shot fun with a small budget
RNG roulette	RNG	Your pace	Bet choice only	Learning a table game cheaply
RNG blackjack	RNG	Your pace	Yes	People who like making decisions
Live dealer	Real equipment, streamed	Slow	Blackjack: yes	A social, real-casino feel
Game shows	Real wheel, streamed	Slow	No	Entertainment-first play
Scratch / instant	RNG	Very fast	No	Very short sessions (set a timer)

How to choose casino sites by play style

There’s no single “right” casino site. The best fit depends on what you want to play, how much you plan to spend and how you feel about bonuses. Work out your play style first, then compare sites on the features that matter to you.

Step 1: work out your play style

Answer these four questions honestly:

1. What will I mostly play? Slots, table games, live dealer, or a mix?
2. What’s my monthly budget? Pick an amount you can afford to lose without it affecting bills, savings or plans.
3. Do I want a bonus at all? A no-wagering offer is simple. A deposit match adds rules you’ll have to follow.
4. How do I like to play? Short, light sessions, or longer sessions at a table?

How your answers map to the play styles below:

• Mostly slots, in short sessions: Casual slots players.
• Not sure yet, or you’d like to look around first: “Try before you deposit” players.
• Roulette, blackjack or live dealer, in longer sessions: Table and live dealer fans.
• Lots of different slots: Explorers who want a big library.
• You want a bonus and are happy to follow its rules: Bonus-curious players. If you’d rather not, skip any offer and choose by the games you play.

What your budget changes. A small monthly budget (say £10–£20) points to low minimum deposits, low stakes and no-wagering offers. A deposit match that needs £20 or more up front and hundreds of pounds of stakes (Example 4) is unlikely to fit.

Can’t choose between slots, roulette and live? Single-zero roulette costs about 2.7p per £1 staked against 4p on a 96% RTP slot, and you set the pace. Slots are simplest but fastest; live games are slowest. All three have an expected loss, so let your budget set how long you play.

Casual slots players

You want a few spins after work, with nothing complicated. Look for:

• a low minimum deposit (£5–£10)
• no-wagering free spins, so winnings from them are cash
• a clear game info screen with the RTP and stake range
• easy deposit limits in your account settings

“Try before you deposit” players

You’d rather see how a site feels before putting money in. Look for a free-to-play demo of the games (after your age check) or a no-deposit offer. These are rarer than deposit offers, and you still have to register and verify your identity first.

Table and live dealer fans

You prefer roulette, blackjack or a live dealer. Look for:

• single-zero roulette and blackjack versions with their rules clearly shown
• low table minimums, if you’re starting small
• named live game studios, so you know what you’ll be playing
• bonus terms that show whether live games count towards wagering (often they don’t)

Explorers who want a big library

You like trying lots of different slots and studios. A large library gives you variety, but check the site’s withdrawal rules and its record with the regulator as closely as you would anywhere else. Size isn’t a sign of quality on its own.

Bonus-curious players

You’d like a welcome bonus, such as free spins or a deposit match. Before you accept one, check:

• wagering (no more than 10x is allowed; lower is better)
• whether it’s charged on the bonus or the deposit
• the maximum bet while the bonus is active
• the time limit, and which games count

Use the maths in Example 4: a bonus is worth much less than its headline figure, and you can always decline it. In the examples below, BetMGM shows a free-spins offer with a one-off qualifying stake, and Casumo shows a deposit match with 10x wagering.

How we picked these examples

How to read a past penalty. A fine or settlement means the Gambling Commission found failings (in these cards, safer gambling and anti-money-laundering checks) and the operator paid. It doesn’t mean the site is unlicensed now. Weigh how recent it was, whether it happened more than once, and whether it was about protecting customers. If a record puts you off, choose another licensed site. Any action against a business is listed on its register page.

Minimum deposit £10; maximum bet is the lower of 50% of the bonus or £20. Plus 11 wager-free spins on Starburst if you deposit £10 within 24 hours of registering.
• Key facts: says it has “over 12,000 casino games”. Minimum withdrawal £20 (smaller amounts on request carry a 3.95% fee). UK residents can’t use payment cards there, according to its casino FAQ. We couldn’t confirm its full list of UK payment methods, so check the cashier before you register. Disputes: IBAS.

Checks every casino site should pass

Whatever your play style, run these four quick checks before you deposit. They take about five minutes.

The licence and the web address match

Find the account number in the site’s footer and search for it on the Gambling Commission public register. Check that remote casino is shown as active, and that the exact web address you’re on appears in the licensee’s list of domains.

The offer terms are in one place

A fair offer page shows the key terms next to the headline: minimum deposit, wagering (10x at most), expiry, eligible games, maximum bet and any cap on winnings. If you have to hunt across several pages, or the pages disagree, wait or skip the offer.

Withdrawal rules are published

Look for the minimum withdrawal, any fees and the published processing time for your payment method. Many sites send withdrawals back to the method you deposited with. If none of this is published, ask support before you deposit.

A withdrawal goes through four stages: you request it, the site reviews it, it’s approved and sent, and the money reaches your payment method (how fast depends on the method). Delays happen at the review. Casumo’s withdrawal policy, for example, says a request can be held or refused if your deposit hasn’t cleared or was charged back, if verification isn’t finished, or while it investigates a problem. Finishing your ID checks at sign-up helps, and the Gambling Commission says a site shouldn’t wait until you withdraw to ask for ID it could have asked for earlier.

There is an independent complaints service

Licensed sites must name an ADR (alternative dispute resolution) provider, such as IBAS or eCOGRA. If a complaint isn’t resolved within 8 weeks, you can take it there for free. Search the site’s terms for “ADR”, “IBAS” or “eCOGRA”.

Safer gambling tools on UK casino sites

Set these up before your first deposit, when you’re calm and not in the middle of a game. Licensed UK sites offer tools like these, though the exact options vary by site.

Limits and time-outs

• Deposit limits: daily, weekly or monthly caps on how much you can add. Decreases usually take effect straight away; increases usually wait at least 24 hours.
• Loss and session limits (on some sites): stop play after a set loss or a set time.
• Reality checks: pop-up reminders of how long you’ve been playing.
• Time-outs: a short break, often from 24 hours to 6 weeks.
• Self-exclusion from one operator, for 6 months or longer.

Some of these tools cover the whole operator, not just one site. LeoVegas’ help centre says a self-exclusion applies across the LeoVegas Gaming PLC licence, which also covers BetMGM, and BetMGM says its deposit limits apply across LeoVegas Group brands. If you want to be sure what a break covers, ask support before you set it. To block every licensed site at once, use GAMSTOP.

GAMSTOP

GAMSTOP is a free service that excludes you from all online gambling companies licensed in Great Britain at once. A licensed casino site must block you while it’s in place.

• You choose the length: 6 months, 1 year or 5 years (5 years can also be set to renew automatically).
• You can’t cancel it early. GAMSTOP’s terms say you can’t remove a self-exclusion before your chosen period ends.
• It doesn’t end by itself. After the period, it stays in place (for up to a further seven years) until you contact GAMSTOP to remove it, and removal only happens after a cooling-off period of at least 24 hours.

Free, confidential help

• National Gambling Helpline (GamCare): call free on 0808 8020 133, 24 hours a day, or use live chat at GamCare.
• BeGambleAware.org (now gambleaware.org): information and a search for support near you in Great Britain.
• Gambling blocks from your bank: many UK banks let you block gambling payments in their app.

Signs it’s time to stop

Take a break and talk to someone if you notice any of these:

• spending more than you planned, or chasing losses
• borrowing money, or using money meant for bills
• hiding your gambling from people close to you
• feeling anxious or low about gambling, or gambling to escape problems

FAQ

What are casino sites?

Casino sites are websites or apps where adults play casino games such as slots, roulette and blackjack for real money. In Great Britain, a site that takes British players must hold a remote casino licence from the Gambling Commission.

Are online casino games rigged?

On licensed British sites, games must be tested by an approved test house before release, and results must be “acceptably random”. Games are also not allowed to adjust results to make up for wins or losses. They are still designed with a house edge, so players lose money on average over time.

What does RTP mean on a casino site?

RTP (return to player) is the share of all stakes a game is designed to pay back over a very large number of plays. A 96% RTP means about £96 back per £100 staked across millions of plays, not in your session. The other 4% is the house edge: the share the casino expects to keep.

Which casino game has the best odds?

There’s no single answer, because odds depend on the version and the rules. Check the RTP or house edge in each game’s info screen. For roulette, single-zero wheels cost less than double-zero wheels (about 2.70% against 5.26%).

Can I play casino games for free first?

Many licensed sites offer free demo versions, but you must verify your age before you can play them. A few sites offer no-deposit free spins, which still require you to register and verify your identity.

Are casino bonuses worth it?

A bonus doesn’t change the expected result of casino play, which is a loss. If you do take one, free spins with no wagering are the simplest: a small deposit and nothing to unlock. Deposit bonuses carry wagering of up to 10x, need a bigger deposit and are worth much less than the headline amount. You can always decline a bonus.

How much can I bet on online slots in the UK?

Up to £5 a spin if you’re 25 or over, and up to £2 a spin if you’re 18–24. These limits apply to online slots, not to table games such as roulette or blackjack.

Do I pay tax on casino winnings in the UK?

【要確認】Players in the UK do not usually pay tax on gambling winnings, but check HMRC guidance for your own situation.

Summary

Casino sites are licensed platforms where adults play slots, table games and live dealer games for real money. Every game has a built-in cost: the house edge, taken from every pound you stake. Your expected loss is that edge multiplied by everything you stake, and if you play until your balance is gone, you lose all of it. Bonuses don’t change that. To choose a site, start with your play style, then check the licence, the offer terms and the withdrawal rules, and switch on your limits before you deposit.
