How to Play — Online Casino Game Rules
Beginner-friendly guide to the rules of slots, blackjack, roulette, baccarat, poker and live dealer games at UK casinos.
Online Slots — How They Work
Slots are the most popular game at every UK online casino. Each spin is determined by a Random Number Generator (RNG) certified by independent testing agencies. No strategy can influence the outcome — every spin is completely independent.
Key Slot Concepts
- RTP (Return to Player): The theoretical percentage returned to players over millions of spins. A 96% RTP means £96 returned per £100 wagered on average. Higher is better — look for 96%+ at UK casinos.
- Volatility: Low volatility = frequent small wins. High volatility = larger but less frequent wins. Medium volatility is the balanced option most players prefer.
- Paylines & Ways to Win: Classic slots use fixed paylines (e.g., 20 lines). Modern slots may offer 243, 1,024 or even 117,649 (Megaways) ways to win.
- Wild symbols: Substitute for other symbols to complete winning combinations
- Scatter symbols: Trigger bonus features regardless of payline position — usually 3 or more required
- Bonus rounds: Free spins, pick-and-click, cascading reels, expanding wilds, multipliers and more
- Progressive jackpots: A portion of every bet across all connected players feeds a growing prize pool. Mega Moolah, Major Millions and Jackpot King are popular in the UK.
- Bonus buy (Feature Buy): Purchase direct access to the bonus round for a premium, typically 50×–250× your stake
Important: All slots at UKGC-licensed casinos use certified RNG technology. Past results have zero influence on future spins. There is no "hot" or "cold" machine — every spin is random.
Blackjack Rules
Blackjack is the most popular table game at UK casinos. The objective is to beat the dealer by getting a hand value closer to 21 without going over (busting).
Card Values
- Number cards (2–10): Face value
- Face cards (J, Q, K): 10 points each
- Ace: 1 or 11 points (whichever is more advantageous)
How to Play
- Place your bet. You and the dealer each receive two cards. One of the dealer's cards is face-up.
- Hit: Request another card
- Stand: Keep your current hand
- Double down: Double your bet and receive exactly one more card
- Split: If you have two cards of the same value, split them into two separate hands (each with its own bet)
- Insurance: A side bet offered when the dealer shows an Ace, paying 2:1 if the dealer has blackjack
Payouts
| Result | Payout |
|---|---|
| Blackjack (A + 10-value) | 3:2 (or 6:5 at some tables) |
| Win against dealer | 1:1 (even money) |
| Insurance (dealer has BJ) | 2:1 |
| Push (tie) | Bet returned |
House edge: 0.5% with optimal basic strategy (European Blackjack). Always choose tables that pay 3:2 for blackjack rather than 6:5.
Roulette Rules
Roulette involves predicting where a ball will land on a spinning wheel. Choose European Roulette (single zero) over American Roulette (double zero) for better odds.
Bet Types
| Bet | Payout | Probability (European) |
|---|---|---|
| Straight up (single number) | 35:1 | 2.7% |
| Split (2 numbers) | 17:1 | 5.4% |
| Street (3 numbers) | 11:1 | 8.1% |
| Corner (4 numbers) | 8:1 | 10.8% |
| Line (6 numbers) | 5:1 | 16.2% |
| Dozen / Column (12 numbers) | 2:1 | 32.4% |
| Red/Black, Odd/Even, High/Low | 1:1 | 48.6% |
House edge: European Roulette = 2.7%. French Roulette with La Partage = 1.35% on even-money bets. American Roulette = 5.26% — avoid this variant.
Baccarat Rules
Baccarat is a straightforward card game where you bet on whether the Player or the Banker will achieve a hand closest to 9, or whether the result will be a Tie.
Card Values
- Ace: 1 point
- 2–9: Face value
- 10, J, Q, K: 0 points
- If the total exceeds 9, only the second digit counts (e.g., 7 + 8 = 15 → 5)
Payouts
| Bet | Payout | House Edge |
|---|---|---|
| Banker | 1:1 (minus 5% commission) | 1.06% |
| Player | 1:1 | 1.24% |
| Tie | 8:1 | 14.36% |
The Banker bet is statistically the best option. The Tie bet has a very high house edge and should generally be avoided.
Video Poker Rules
Video poker combines slots with poker strategy. You are dealt five cards, choose which to hold, and draw replacements. Wins are based on the standard poker hand rankings.
Jacks or Better — Hand Rankings
| Hand | Payout (9/6 Jacks or Better) |
|---|---|
| Royal Flush | 250:1 (4,000 coins max bet) |
| Straight Flush | 50:1 |
| Four of a Kind | 25:1 |
| Full House | 9:1 |
| Flush | 6:1 |
| Straight | 4:1 |
| Three of a Kind | 3:1 |
| Two Pair | 2:1 |
| Jacks or Better | 1:1 |
House edge: As low as 0.46% on 9/6 Jacks or Better with optimal strategy — one of the best RTPs in any casino game.
Live Dealer Games
Live dealer games stream real dealers from professional studios directly to your device via HD video. You place bets through the digital interface while the dealer manages the game on camera in real time.

Responsible play reminder: All casino games carry a house edge — the casino always has a mathematical advantage. Set a budget before you play and never bet more than you can afford to lose. Games should be treated as entertainment, not as a way to make money. 18+ only.
