Craps Strategy: What Works and What Doesn't

Craps strategy: what works and what doesn't

Craps carries a reputation for complexity that it doesn't quite deserve. Strip away the table layout and the croupier's jargon, and the strategic core comes down to a handful of bets with genuinely low house edges, surrounded by a much larger number of bets that quietly eat your bankroll. Knowing which is which is essentially the whole game.

This guide covers the bets worth making, the ones worth skipping, why betting systems don't do what their advocates claim, and what "strategy" realistically means at a game run by fixed probabilities.

What the house edge tells you

Every casino bet carries a built-in mathematical advantage in the casino's favour, expressed as a percentage. Put £100 through a game with a 5% house edge, and your expected return over time is £95. That doesn't mean you lose £5 every time - variance means you might win big on any given session. But over a large enough sample, the edge is what decides where the money ends up.

Craps is unusual among casino table games because its best bets carry house edges well below 2%, placing them alongside the most player-friendly options in any UK casino. Its worst bets, the proposition bets clustered in the centre of the table, carry edges pushing 17%. The distance between those two figures is the whole of craps strategy.

The bets worth making

Pass line. The standard opening bet, placed before the come-out roll. If the shooter rolls a 7 or 11, you win. Roll a 2, 3, or 12 (craps), you lose. Any other number becomes the "point", and the shooter keeps rolling until they repeat it (you win) or hit a 7 (you lose). House edge: 1.41%.

Don't pass. The other side of the same bet. You're betting against the shooter: win on 2 or 3, lose on 7 or 11, push on 12. Once a point is set, you win if a 7 appears before it's repeated. Edge: 1.36%, marginally better than pass.

Come and don't come. These work on exactly the same logic as pass and don't pass, but are placed after the point is established. Any number rolled becomes that bet's personal point. House edges are identical to their equivalents.

Place bets on 6 and 8. These let you bet directly on a specific number appearing before a 7. The 6 and 8 are the two most common non-7 outcomes on two dice, and placing either carries an edge of just 1.52%. The 5 and 9 jump to 4%, and the 4 and 10 to 6.67%, making those the pairs to pass on.

Free odds: the closest thing to a free lunch

The odds bet is unique in casino gambling: it carries a 0% house edge. Once a point is established, you can back your pass or come bet with an additional wager placed behind the line. This pays at true mathematical odds - 2:1 on a point of 4 or 10, 3:2 on 5 or 9, 6:5 on 6 or 8 - so the house makes nothing on it.

Casinos allow different multiples: typically 2x, 3-4-5x, or 10x your original bet depending on the table. Taking the maximum odds your bankroll allows is the single most effective move in craps, because it shifts a larger proportion of your money onto a bet the house doesn't profit from. On a 3-4-5x odds table with a pass line bet and full odds behind it, the combined house edge on both bets falls to around 0.37%.

That's not a trick. It's basic weighted-average maths. The free odds bet is available at every craps table, and taking it is the closest structural advantage a player can actually secure.

The bets to avoid

The proposition bets in the centre of the craps table are designed to look exciting. Most settle on the next roll, which adds pace, and the headline payouts look large. The edges, though, are punishing.

Any Seven. A bet that the next roll is a 7. Pays 4:1. House edge: 16.67%. The worst single standard bet at the table.

Any Craps. A bet on 2, 3, or 12 appearing on the next roll. House edge: 11.11%.

Hardways. A bet that a specific number will appear as a matching pair (two 2s for a hard 4, two 5s for a hard 10) before either a 7 or an "easy" combination of that number. Edges range from 9.09% on the hard 6 and 8 to 11.11% on the hard 4 and 10.

Field bet. Covers 2, 3, 4, 9, 10, 11, and 12, settled on the next roll. The edge depends on table rules: if both 2 and 12 pay 2:1, it sits at 5.56%. Some tables pay 3:1 on 12, bringing it to 2.78%, which is still worse than the pass line but acceptable if you prefer resolved bets.

Big 6 and Big 8. Functionally identical to place bets on 6 or 8 but paying even money instead of 7:6, pushing the edge from 1.52% to 9.09%. There is no reason to use these over the equivalent place bets.

The pattern throughout: the faster a bet resolves and the bigger the payout looks, the worse it tends to be.

Betting systems: why they don't change the maths

Martingale, Paroli, D'Alembert, Iron Cross. Craps has collected a longer list of named betting systems than almost any other game. The appeal is real: they impose structure, make losses feel managed, and often produce long runs of small wins. None of them alter the house edge.

The Martingale involves doubling your bet after every loss to recover everything in a single win. It works in practice, often for a good while. The problem is the rare but catastrophic session where a losing streak outpaces the table maximum or your bankroll, producing a single loss that wipes out every previous small win combined. Mathematically, expected losses over time are the same as flat betting with the same total stakes.

The Iron Cross, which combines a field bet with place bets on the 5, 6, and 8, wins on every roll except a 7, and has picked up a near-cult following online. What it actually does is spread money across bets with an average edge well above the pass line, and any 7 - which falls on average once in every six rolls - takes the lot. It's an entertaining way to play, not a route to better odds.

No betting system can shift the probability of a random game. The dice have no memory. This is worth underlining because online craps at UK-licensed sites is governed by UKGC technical standards: RTS 7 specifically prohibits adaptive or compensated games that adjust outcomes based on past results. The same principle holds at a live table. No sequence of previous rolls has any bearing on the next one, which is why the fairness mechanics that apply to online casino games are the same at a craps table as anywhere else.

Online craps and live dealer: does strategy change?

Strategy is the same online as at a physical table, because the maths is the same. Pass line, free odds, come bets, and place bets on the 6 and 8 give you the best returns in any format.

There are practical differences worth noting. RNG craps, the standard digital version, lets you take as long as you like on each decision, which makes it easier to learn the layout and think through bet sizing. Live dealer craps, offered at several UK-licensed sites, uses a real croupier and real dice over a video feed with the same bet types and odds. Some players prefer the social element; it makes no mathematical difference to strategy.

Table minimums do matter online. Many RNG tables start at £1, making it practical to take full odds on a small session budget. Live dealer minimums tend to be higher, and odds multiples can vary by operator, so it's worth reading the table rules before sitting down. Our guide to the best online casinos covers the UK-licensed options where table game selections are worth the look.

Bankroll and table time

Craps plays faster than many table games, and that pace matters. Even a 1.41% edge compounds if you're putting large amounts through quickly. The practical upshot is that a session budget applied to craps can disappear faster than the edge figure alone suggests - game speed is as important a variable as the house edge when thinking about how long your money lasts.

A few anchor points:

• Set a session budget before you sit down. A decision made in advance, outside a losing run, holds better than one made mid-session.
• Take free odds up to whatever your bankroll allows. On a 3-4-5x table with a modest budget, 1x odds is still better than none.
• Pass and come bets take longer to resolve than proposition bets, meaning fewer decisions per hour and more table time for the same money. That slower pace is a feature, not a drawback.

Setting a deposit limit before you play is the cleanest way to enforce a session budget - it removes the option to add funds mid-session when things go badly, and it works regardless of what you're playing.

What craps strategy realistically offers

The honest version of craps strategy is this: it reduces what the casino takes from you, but it doesn't make you a long-term winner. The pass line with full odds, at around 0.37% combined on a 3-4-5x table, is about as good as it gets. Played at pace over many sessions, you're still paying to play.

The realistic goal is to stretch your money further, keep variance manageable, and make decisions you actually understand. A player who sticks to the pass line and free odds will outlast and outperform one throwing money at Any Seven and the Hardways, on average, and with far less volatility along the way.

That matters because what most people are actually paying for is the experience: the pace, the energy of a table, the runs of winning rolls. Good strategy lets you buy more of that for the same cost.

Frequently asked questions

What is the best bet in craps? The pass line or don't pass bet combined with a free odds bet gives the lowest combined edge in the game: as low as 0.37% on a 3-4-5x odds table. The free odds portion pays at true mathematical odds, so the casino makes nothing on it.

Does craps strategy guarantee wins? No. The house edge means that over enough play, the casino profits regardless of strategy. What good strategy does is reduce how much the house takes per pound wagered and cut the volatility of your sessions.

What bets should you avoid in craps? Proposition bets in the centre of the table carry the highest edges: Any Seven at 16.67%, Hardways ranging from 9% to 11%, and Any Craps at 11.11%. The Big 6 and Big 8 are also best avoided in favour of equivalent place bets, which pay better for the same outcome.

Is online craps fair at UK sites? Yes. UK-licensed online craps must use a certified random number generator. RTS 7, the relevant UKGC technical standard, requires genuinely random outcomes and explicitly bans adaptive or compensated games that adjust results based on past rolls.

Does the Martingale system work at craps? Not in a durable sense. It produces frequent small wins but doesn't change the house edge. A losing streak that hits the table maximum or exhausts the bankroll wipes out all prior gains at once. Expected losses over time match flat betting with the same total stakes.

What does a 3-4-5x odds table mean? You can take 3x your pass line bet as odds on a point of 4 or 10, 4x on a point of 5 or 9, and 5x on a point of 6 or 8. With full odds taken, the combined house edge on both bets drops to around 0.37%.
