Casino dice games explained

What counts as a casino dice game

Casino dice games are the part of the casino games lobby where a roll decides the result instead of a card or a wheel. Online you will meet them in three forms: RNG versions with animated dice, live studio tables where a machine or dealer rolls real dice on camera, and game-show hybrids that add random multipliers on top of a dice roll.

The two classics are craps, played with two dice and famous for its busy layout, and sic bo, a three-dice game with roots in China that offers bets on totals, doubles, triples and single numbers. Newer titles such as Lightning Dice and the dice-based baccarat game Bac Bo borrow the same probabilities and package them differently.

What unites all casino dice games is that you can calculate the true odds with nothing more than a pen. That makes them a useful place to learn how a house edge is built: the casino pays a little less than the true odds, and the gap is its margin.

Dice probability: the maths behind every casino dice game

Each die has six faces, so two dice produce 6 × 6 = 36 combinations and three dice produce 6 × 6 × 6 = 216. Totals in the middle can be made more ways than totals at the edges, which is why 7 is the most common two-dice total and 10 and 11 are the most common three-dice totals.

With those counts you can test any paytable yourself. If a bet wins x ways out of N and pays p to 1, the expected return per £1 is (x × (p + 1)) ÷ N. Anything below £1 is the house edge. The guide to understanding casino odds walks through the same method for other games.

How to play casino dice games online, step by step

The steps below follow a round of RNG sic bo, the simplest dice game to start with. Craps adds a two-stage structure, explained in the next section.

1. Open the game and read the paytable in the help screen, because sic bo payouts vary between versions.
2. Choose a chip value within the table's minimum and maximum.
3. Place bets on the layout, for example Small (total 4 to 10) or Big (total 11 to 17).
4. Press roll. You must start each round yourself, since autoplay is banned on UK online casino games.
5. The three dice are shown, winning bets are paid and losing chips are collected.
6. Check your net position on screen before deciding whether to play another round.

Small and Big both lose to any triple, which is where the house edge on those even-money bets comes from. Out of 216 outcomes, 105 win, 111 lose (including the 6 triples), giving an edge of 6 ÷ 216 = 2.78%.

Craps: the two-dice casino game in brief

A craps round starts with a come-out roll. On the pass line, a 7 or 11 wins straight away and a 2, 3 or 12 loses. Any other total (4, 5, 6, 8, 9 or 10) becomes the point, and the dice keep rolling until either the point repeats (pass wins) or a 7 appears (pass loses). The don't pass bet is roughly the mirror image, with 12 on the come-out treated as a push in most rule sets.

That structure gives the pass line a house edge of about 1.41% and don't pass about 1.36%, among the lowest standard edges in any casino. Where a game offers a free odds bet behind the pass line, that extra stake is paid at true odds, so it carries no house edge of its own, though the pass bet it sits behind still does. The Wizard of Odds craps analysis (opens in a new tab) breaks down every bet in detail.

Casino dice games: bets, payouts and house edge

The table below lists common bets with typical payouts and their house edge under standard rules. Online versions differ, especially on sic bo totals and triples, so the help screen of the game you open always takes priority.

The last two rows show why paytables matter. The same specific-triple bet costs almost twice as much at 150 to 1 as at 180 to 1, because the true odds (215 to 1) never change while the payout does. Live dice titles with multipliers, including Lightning Dice and Bac Bo, set their own payouts; their published RTP figures sit in the game's info panel, and you should read them there rather than rely on numbers repeated elsewhere.

RNG v live casino dice games

RNG dice games draw each result from certified software, while live dice games use physical dice in a shaker or a tumbling machine filmed in a studio. The probabilities are identical if the dice are fair, and both kinds of game are tested before they can be offered in Great Britain. The practical difference is pace and atmosphere.

• RNG tables start when you press roll and, under UK rules, cannot begin a new game cycle within 5 seconds of the previous one starting.
• Live tables run on a studio timer with a betting window, so rounds come far less often and you share the result with other players.
• Game-show dice titles add multiplier draws, which reshape payouts so that some outcomes pay far above the base table and many pay less.

If you are deciding between formats, our page on the live casino explains how studio games are run, and how casino games are tested covers the RNG side.

UK rules for online dice games

Dice games count as non-slot casino games under the Gambling Commission's Remote Technical Standards. From 17 January 2025 the Commission extended its game design rules beyond slots, including a minimum of 5 seconds per game cycle (opens in a new tab) on these games, measured from the start of one game to the start of the next.

• No autoplay: each roll must be started by you. See the autoplay ban.
• Net position and elapsed time must be shown during a session.
• Playing several casino games at the same time is restricted under the 2025 changes.
• The £5 and £2 slot stake limits do not apply to dice games; table limits are set per game.

Credit cards cannot be used to gamble in Great Britain, a rule in force since 14 April 2020, so deposits come from debit cards, bank payments or e-wallets funded by debit. See the credit card ban for the detail.

Dice myths and betting systems

Dice games attract more folklore than most, partly because land-based craps is loud and social. Online, none of it applies.

• Hot shooters. A streak of point wins is just variance. The next roll has the same 6 in 36 chance of a 7 as every other roll.
• Dice control. Whatever people claim about controlled throws on a real table, there is no throw to control in an RNG game or a mechanical shaker.
• Overdue numbers. If 8 has not appeared for 30 rolls, it is no more likely on roll 31. That belief is the gambler's fallacy.
• Hedging every number. Covering many bets at once does not lower the edge; it adds the edges of every bet together.

The same goes for progression systems. Raising your stake after losses or wins changes how results bunch together, not the average cost. The arithmetic is set out in casino betting systems, and gambling myths covers a wider list.

Bankroll maths for dice games

The cost of a dice session is your total amount wagered multiplied by the house edge of the bets you choose. Two players with the same £50 budget can face very different average costs.

The averages hide large swings. A specific triple might hit once and pay £300 on a £2 stake, or not appear at all across 100 rolls, which happens most of the time: the chance of no specific triple in 100 rolls is about 63%. Set a bankroll for the session and stop when it is gone, and read our casino bankroll basics for more on sizing stakes.
