The question hides a second question
When someone asks which casino game has the best odds and then names craps, they are usually asking two different things at once. The first is whether craps as a whole is a better place to put money than other table games. The second, sharper question is which bet on the craps table gives the player the smallest expected loss. Those have different answers, because a craps table is not one game. It is a collection of bets with edges that range from close to even all the way to genuinely expensive.
The useful way to think about this is expected value. Every wager on the table has a built-in mathematical advantage for the house, expressed as a percentage of the amount staked. The player's job, if the goal is to lose as slowly as possible, is to find the bets where that percentage is smallest and avoid the ones where it is large. The table itself gives you the tools to do that.
How the edge is built into each bet
Craps is played with two six-sided dice, which produce 36 equally likely combinations. The payouts printed on the felt are set slightly below what a fair payout would be for the true odds of each outcome. That gap is the house edge. It is not a fee collected at the end of the session. It is embedded in every single roll, because the bet pays less than its mathematical probability would justify.
Take the pass line as the reference point. On the come-out roll, a 7 or 11 wins immediately and a 2, 3 or 12 loses immediately. Any other number becomes the point, and the shooter then tries to roll that point again before a 7 appears. The payout is even money, but the probability of winning is slightly below 50 percent once the whole sequence is accounted for. That small shortfall, repeated across thousands of decisions, is the edge.
The important distinction is between the line bets and the proposition bets in the centre of the table. Proposition bets offer large printed payouts, but the true odds against them are even larger. The gap between the printed payout and the true odds is where the house makes its money, and on some of those centre bets the gap is wide.
Comparing the main bets
The bets below behave very differently, and the difference in expected loss between the best and the worst is far larger than most new players assume. The percentages here are not operator-specific; they follow from the fixed geometry of two dice and the standard payouts printed on the layout.
| Bet | What it does | Why the edge differs |
|---|---|---|
| Pass line | Wins on 7 or 11 on the come-out; loses on 2, 3 or 12; otherwise sets a point to be repeated before a 7. | Even-money payout against slightly worse than even true odds; the shortfall is small. |
| Don't pass | The reverse of the pass line, except a 12 on the come-out usually pushes instead of winning. | Pays even money with a slight probability advantage, reduced by the push rule. |
| Come / don't come | The same structure as pass and don't pass, but started after the point is established. | Same edge as their line counterparts; they are separate bets, not a continuation of the first. |
| Odds bet | An additional wager behind a pass, don't pass, come or don't come bet after a point is set. | Pays true odds with no house advantage; only available once a line bet exists. |
| Place bets on 6 and 8 | Bet that a 6 or 8 appears before a 7. | Payout is below true odds; the edge is moderate compared with other place numbers. |
| Field bet | One-roll bet on 2, 3, 4, 9, 10, 11 or 12, sometimes with a higher payout on 2 or 12. | Many winning numbers but many more losing combinations; the edge depends on the printed special payout. |
| Any 7 | One-roll bet that the next roll is a 7. | Pays 4 to 1 while the true odds are 5 to 1 against; the gap is large. |
The odds bet is the anomaly on the table. It is the only standard craps wager that pays at the true mathematical odds of the outcome, which means the house has no built-in edge on that portion of the money. The catch is structural: you cannot place an odds bet on its own. It exists only as an attachment to a line bet that already carries an edge. The combined expected loss across both wagers is therefore lower as a percentage of total money staked than the line bet alone, but it is never zero, because the line bet is always part of the package.
Why short sessions look nothing like the average
House edge and RTP are long-run statistical averages. They describe what happens across a very large number of decisions, not what happens in the next hour. A pass line bet with a small edge does not lose a small amount every time. It loses the whole stake on some decisions, wins the whole stake on others, and occasionally produces a long sequence of either result.
This is the difference between expected value and variance. Expected value is the slow drift created by the payout gap. Variance is the wild up-and-down created by the fact that each roll is an independent event with a limited set of outcomes. A player can sit at a table for an evening, make only pass line bets with odds, and still lose several buy-ins. That does not mean the edge was mis-stated. It means the session was too short for the average to dominate.
The reverse is also true. A player can win on a terrible bet like any 7 for an hour. The edge is still there; it simply has not had enough repetitions to show itself. The house builds its business on the fact that enough players make enough bets for the average to win out over time.
Decisions per hour change total exposure
The edge is a percentage of each wager, which means the total expected loss is the edge multiplied by the total amount wagered across the session. Two players can sit at the same table with the same bankroll and face very different expected losses because they make different numbers of decisions per hour.
As an example, suppose a player makes 30 pass line bets per hour at 10 units each, with a house edge of 1.4 percent on that bet. The expected loss for the hour is 30 multiplied by 10, multiplied by 1.4 percent, which is 4.2 units. If the same player adds a full odds bet behind each pass line bet, the total staked rises sharply while the expected loss rises only slightly, because the odds portion carries no edge. The combined expected loss as a percentage of total money staked falls, even though the absolute expected loss in units is similar.
A player who instead makes 60 field bets per hour at the same stake, on a field bet with a larger edge, multiplies both the number of decisions and the rate of loss per decision. The game speed and the bet selection work together. A slow game with good bets loses less than a fast game with bad bets, even when both players start with the same money.
Progression systems redistribute, they do not remove
Betting systems that raise the stake after a loss, or after a win, are popular at the craps table because the game produces long streaks that make a progression feel like it is working. The honest mechanism is less flattering. A progression does not change the probability of any roll, and it does not change the payout gap on any bet. It changes the size of the wagers placed at different points in the sequence.
What that does is reshape the distribution of outcomes. Most of the time, a progression produces a small win, because the player recovers a previous loss with a larger bet. Occasionally, it produces a very large loss, because a losing streak runs long enough to exhaust the bankroll or hit the table maximum. The expected value of the sequence is the same as the expected value of flat betting the same total amount. The system has moved the losses around, not removed them.
At a craps table, the table maximum is the hard boundary that makes this visible. A doubling progression after losses can only continue for a few steps before the required bet exceeds the posted limit. At that point the player cannot place the bet that would recover the accumulated loss, and the sequence ends with a realised loss. The edge was always there; the progression simply delayed when it would be collected.
What the player controls
No bet selection changes the fact that the house holds an edge on every wager except the odds bet, and the odds bet cannot stand alone. What the player controls is the rate of loss and the shape of the session. Choosing pass or don't pass with odds, or come bets with odds, keeps the expected loss per unit staked as low as the table allows. Avoiding the centre proposition bets keeps the expensive edges out of the session. Slowing down the number of decisions per hour reduces total exposure. Setting a stop-loss and a session length controls how much of the bankroll is put at risk.
None of that is a winning strategy in the sense of reversing the edge. It is a method for making the bankroll last longer and for understanding what is happening to the money while it lasts. The player who knows the edge on each bet, and knows that variance will dominate any single evening, is the player who is not surprised by either a long win or a sudden loss.
FAQ
Does the odds bet really have no house edge?
Yes, as a standalone wager it pays at true odds, so the house has no mathematical advantage on that portion of the money. But it cannot be placed without a line bet, and the line bet carries an edge. The combined position therefore still has a positive house advantage, just a smaller one as a percentage of total money staked.
Are don't pass and don't come better than pass and come?
They carry a very similar edge, and in some rule sets the don't side is marginally lower. The difference is small enough that table conditions, the player's comfort with betting against the shooter, and the specific push rule on the come-out matter more than the tiny edge difference.
Can a betting system overcome the craps house edge?
No. A progression changes the size of bets, not the probability of any roll or the payout gap on any bet. It redistributes outcomes, producing many small wins and occasional large losses, with the same expected value as flat betting the same total amount.
