Casino games guide: what this section covers
Casino games split into a handful of families, and this section gives each one its own hub with rules, odds and the maths behind every bet. Card games against the dealer sit in blackjack, baccarat and casino poker. Wheel and dice games live under roulette, craps and sic bo and other dice games. Machine-style card play has its own video poker hub, and bingo, keno, Slingo and crash games are grouped in specialty games.
Streamed tables and studio shows get separate treatment, because the dealer, the pace and some of the rules change: see live casino for the tables and studios, and live game shows for wheels such as Crazy Time. Slots have their own section, reached from the main menu.
Every game page follows the same order: how a round works, what each bet pays, how often it wins, what that costs you on average, and which rules or choices move the numbers.
Casino games odds compared: the house edge on the main bets
The house edge is the share of each stake the game keeps on average over a very long run. Multiply it by your stake and you get the average cost of one bet. The figures below are standard game maths from Wizard of Odds, each with the rules it assumes.
| Game and bet | Rules assumed | House edge | Average cost per £10 |
|---|---|---|---|
| Video poker: Jacks or Better | 9/6 pay table, perfect strategy | 0.46% | 4.6p |
| Blackjack | Six decks, European no-peek, basic strategy | 0.62% | 6.2p |
| Baccarat: Banker | Eight decks, 5% commission | 1.06% | 10.6p |
| Craps: Pass line | Standard rules | 1.41% | 14.1p |
| Casino Hold'em | Most common ante pay table | 2.16% of the Ante | 21.6p per £10 Ante |
| Roulette: any bet | Single zero | 2.70% | 27p |
| Sic bo: Small or Big | Loses on any triple | 2.78% | 27.8p |
| Three Card Poker: Ante and Play | Common Ante Bonus table | 3.37% of the Ante | 33.7p per £10 Ante |
| Roulette: any bet | Double zero | 5.26% | 52.6p |
| Baccarat: Tie | Pays 8 to 1, eight decks | 14.36% | £1.44 |
| Keno | Typical land-based pay tables | 25% to 29% | £2.50 to £2.90 |
These are long-run averages, not predictions. Any single session can finish well ahead or well behind, and the edge only shows itself over thousands of bets. The house edge explained page shows the formula and more worked examples.

How to choose which casino game to play
Start with the edge, then think about speed, because cost per hour is edge × stake × rounds. Suppose you play 60 rounds an hour at £10: single-zero roulette costs about £16.20 an hour on average, while blackjack played with basic strategy under the rules above costs about £3.72. The same budget lasts very differently.
- Want the lowest cost with no decisions? The Banker bet in baccarat or the Pass line in craps.
- Happy to learn a strategy? Blackjack and video poker reward correct play; mistakes push the edge up.
- Like big multipliers? Live game shows and Lightning-style tables pay more on rare outcomes but usually return less overall.
- Watch the side bets. Most carry far higher edges than the main game.
No betting system or pattern changes these figures. Our guide to choosing a game walks through budget, pace and cost in more detail.
UK rules for online casino games
Online casino games offered in Great Britain must come from operators licensed by the Gambling Commission, and you must pass age and identity checks before you deposit or play, even in demo mode. Since 17 January 2025, autoplay is banned for all online casino games, live tables included, and games other than slots must allow at least 5 seconds per game cycle. The £5 and £2 stake limits apply to online slots only, not to blackjack, roulette or other table games. Operators must also make the rules and the RTP or house edge of each game available before you bet, under the Commission's remote technical standards on game rules and the likelihood of winning (opens in a new tab). More detail sits in our UK game speed rules guide.
18+. Every casino game has a built-in house edge, so over time you should expect to lose what you stake. Set a budget before you play and stop when it’s gone: safer gambling tools and support. Free, confidential help: National Gambling Helpline 0808 8020 133.
Frequently asked questions
Which casino games cost the least to play?
Among common games, blackjack played with correct basic strategy and full-pay video poker played perfectly have the lowest edges, roughly 0.5% depending on the rules or pay table. Among bets that need no decisions, baccarat's Banker bet (1.06%) and the craps Pass line (1.41%) cost least. The lowest house edge games page compares them with worked examples, and every figure depends on the exact rules shown in the game's help screen.
How do I know casino games online are fair?
Play only at casinos licensed by the Gambling Commission. Under the Commission's technical standards, RNG games must produce results that are acceptably random and match the stated probabilities, and games and random number generators are tested by approved test houses before release. Live games use physical cards, wheels and dice in a studio. Randomness does not remove the house edge: it means results can't be predicted. Our page on random number generators explains how the testing works.
Is live casino better value than RNG games?
Not automatically. A live single-zero roulette table and an RNG version have the same 2.70% edge because the maths is identical. Live games run more slowly, so you usually make fewer bets an hour, which can cut your hourly cost. Some live variants add fees or lower base payouts to fund multipliers. Compare both on our live casino versus RNG page before choosing.
Can a strategy beat casino games?
No. Strategy can lower the house edge in games with decisions, such as blackjack and video poker, but it can't turn it in your favour, and no betting system changes the edge on any bet. Martingale-style systems only rearrange when you win and lose, and they risk large losses against table limits. Our casino strategy section focuses on what strategy can do: making a budget last and avoiding expensive bets.
Do the slot stake limits apply to table games?
No. The £5 per spin limit for adults aged 25 and over, and the £2 limit for 18 to 24-year-olds, apply only to online slots, meaning reel-based casino games. Blackjack, roulette, baccarat and live tables set their own minimum and maximum bets, shown on the table. Other rules do cover them, including the autoplay ban and the 5-second minimum game cycle. See slot stake limits for the full rule.
