Craps Odds Explained: Understanding the Best and Worst Bets on the Table

Walk past a craps table in any busy casino and the energy is unmistakable — players cheering, chips flying, a shooter blowing on the dice. But beneath the noise and ritual, craps is a game built on mathematics, and the odds vary so dramatically between different bets that two players standing at the same table can be experiencing completely different house edges. Understanding those odds is what separates the player who slowly grinds their bankroll down on sucker bets from the one who stretches their session by sticking to the smartest wagers the game offers.

The Basic Structure of a Craps Round

Before odds make sense, the game's rhythm needs to be clear. A round of craps begins with the come-out roll. The shooter throws two dice, and the result falls into one of three categories. A natural — rolling a 7 or 11 — wins immediately for Pass Line bettors. Craps — rolling a 2, 3, or 12 — loses for Pass Line bettors. Any other number (4, 5, 6, 8, 9, or 10) becomes the point. Once the point is established, the shooter keeps rolling until they either hit that point number again, which wins, or roll a 7, known as sevening out, which loses.

This two-stage structure is fundamental because it means the odds are not static across a single round. The probabilities shift depending on whether you are in the come-out phase or the point phase, and the bets you can make change accordingly.

How Probability Works With Two Dice

Two standard six-sided dice produce 36 possible combinations. This is the foundation of every odds calculation in craps. The number 7 can be made six different ways, which is why it dominates the game — it is the most likely outcome on any given roll, appearing roughly once every six throws. The number 6 and the number 8 can each be made five ways. The numbers 5 and 9 can each be made four ways. The numbers 4 and 10 can each be made three ways. The extremes — 2 and 12 — can only be made one way each.

This distribution is not just trivia. It directly determines the payouts that would make a bet fair, and comparing those fair payouts to the actual payouts offered by the casino reveals the house edge on every single wager.

The Pass Line Bet: The Cornerstone of Craps

The Pass Line bet is the most fundamental wager in the game and one of the best bets in the casino. The house edge on a Pass Line bet is approximately 1.41 percent. To understand where that comes from: during the come-out roll, there are 8 ways to win (the six ways to roll a 7 plus the two ways to roll an 11) and 4 ways to lose (one way to roll a 2, two ways to roll a 3, and one way to roll a 12). If a point is established, the player then needs to roll that point before a 7 appears.

The probability of making each point varies considerably. A point of 6 or 8 can be hit five ways versus six ways to roll a 7, giving the player a 5-in-11 chance of winning once the point is set. A point of 4 or 10 can be hit only three ways versus six ways to roll a 7, making it a 3-in-9 — or 1-in-3 — chance. Taking all possible come-out outcomes and all possible point resolutions together, the Pass Line bet results in that 1.41 percent house edge. For a table game, that is excellent value.

The Don't Pass Bet: Playing the Dark Side

The Don't Pass bet is essentially the opposite of the Pass Line. The bettor is wagering that a 7 will appear before the point is rolled again. Because the casino needs a house edge on both sides, the rules are adjusted slightly — a come-out roll of 12 is a push (a tie) rather than a loss for the Don't Pass bettor. This one rule adjustment keeps the house edge on the Don't Pass bet at around 1.36 percent, marginally lower than the Pass Line. Don't Pass bettors are sometimes called wrong bettors, though the label is misleading — mathematically, there is nothing wrong about it at all.

The Free Odds Bet: Zero House Edge

Here is where craps becomes genuinely extraordinary among casino games. Once a point is established, a Pass Line or Don't Pass bettor can place an additional wager behind their original bet called the Odds bet. Unlike every other bet in the casino, the Free Odds bet carries zero house edge. The casino pays it at exactly true odds — the mathematically correct payout that reflects the real probability of the outcome.

For a point of 4 or 10, true odds are 2-to-1, so a winning Odds bet pays double. For a point of 5 or 9, true odds are 3-to-2. For a point of 6 or 8, true odds are 6-to-5. Many casinos allow players to take Odds bets of double, triple, or even ten times their original bet. The more you place on free odds, the lower the combined house edge on your total wager becomes. At 3x-4x-5x odds — a common casino offering where the maximum Odds multiple varies by point — the combined house edge on the entire Pass Line plus Odds wager drops to around 0.37 percent. That is among the lowest house advantages of any casino game anywhere.

Come and Don't Come Bets

The Come bet works exactly like the Pass Line bet but is placed after the point has been established. Once placed, the next roll becomes the Come bettor's personal come-out roll. A 7 or 11 wins immediately, a 2, 3, or 12 loses, and any other number becomes the bettor's own Come point. The dealer moves the Come chip to the corresponding number box. From that point, the bettor wins if that number rolls before a 7.

Come bets carry the same 1.41 percent house edge as Pass Line bets and can also be backed with Free Odds. For players who want more action beyond the single Pass Line bet without moving into higher-edge territory, Come bets are the logical extension. The Don't Come bet is the mirror image, with similar logic to the Don't Pass and a comparable house edge.

Place Bets: Decent Value on Some Numbers

Place bets allow players to wager directly on specific numbers — 4, 5, 6, 8, 9, or 10 — without waiting for a Come point to be established. The house edge varies significantly depending on which number you place.

Place 6 and Place 8: These pay 7-to-6 on a true odds payout of 6-to-5, resulting in a house edge of 1.52 percent. Respectable value.
Place 5 and Place 9: These pay 7-to-5 on a true odds payout of 3-to-2, producing a house edge of 4.00 percent. Noticeably worse.
Place 4 and Place 10: These pay 9-to-5 on a true odds payout of 2-to-1, giving a house edge of 6.67 percent. Much harder to justify.

The practical takeaway is that Place bets on 6 and 8 are reasonable additions to a strategy. Place bets on 4 and 10 are genuinely expensive and should generally be avoided if you have Pass Line and Come bets available to you.

The Proposition Bets: High Excitement, High Cost

The centre of the craps layout is where proposition bets live, and it is where the house earns the most money. These one-roll bets look exciting and pay large numbers, but the house edges are punishing.

Any 7: Pays 4-to-1. True odds are 5-to-1. House edge: 16.67 percent.
Any Craps (2, 3, or 12): Pays 7-to-1. True odds are 8-to-1. House edge: 11.11 percent.
Hardways (e.g., Hard 6 — rolling 3+3): Hard 6 and Hard 8 typically pay 9-to-1 with a house edge around 9.09 percent. Hard 4 and Hard 10 often pay 7-to-1 with an edge near 11.11 percent.
Yo (11): Pays 15-to-1. True odds are 17-to-1. House edge: 11.11 percent.

These bets are not inherently evil — a small proposition wager adds entertainment for many players — but using them as a core strategy is an expensive way to play. The numbers make it clear: the house is extracting between ten and seventeen cents from every dollar wagered on these bets over time, compared to less than two cents on the Pass Line.

Field Bets and the Power of Reading Payouts

The Field bet is a one-roll wager that pays even money if the roll lands on 3, 4, 9, 10, or 11, and double on 2, with some casinos paying triple on 12. The house edge sits around 5.56 percent in most versions, though it drops to roughly 2.78 percent in casinos offering the triple payout on 12. The Field bet illustrates an important principle: the exact payout structure dramatically alters the value of a wager. Reading the table felt carefully before betting is always worthwhile.

Building a Smart Craps Strategy

The data points to a clear strategic framework. Start with a Pass Line bet. Back it with the maximum Free Odds the table allows. If you want broader coverage, add one or two Come bets, again with maximum Odds. Optionally add Place bets on 6 and 8. Avoid the centre of the table almost entirely.

This approach keeps your combined house edge well below one percent in many cases. It does not guarantee winning sessions — no strategy can do that — but it ensures that the mathematical erosion of your bankroll is as slow as possible, giving you the most play for your money and the best statistical chance of walking away ahead on any given night.

Craps rewards players who take the time to understand its structure. Once you see the numbers behind the noise, the table feels less chaotic and a great deal more navigable.
