Ready to take the mystery out of craps? Let us get rolling.
What Are Craps Odds Bets?
Craps odds bets are extra wagers you can add after a point has been established. They sit behind an existing Pass Line or Don’t Pass bet and are accepted only after that original wager is in place.
What sets odds bets apart is that they pay true odds, meaning the payout matches the mathematical probability of the outcome. Because of that feature, odds bets do not carry the casino margin that most other bets do. They simply reflect the real chances of the point being made or a 7 appearing first.
Odds bets offer another way to tailor your play around the point number and the size of your original stake. They do not guarantee a win, but they do provide a straightforward, mathematically fair payout when they succeed.
Understanding Probabilities in Craps: How Do They Work?
Probabilities in craps describe how likely particular totals are to appear on a roll of two dice. Each possible total corresponds to a number of combinations of the dice, so outcomes with more combinations occur more often in the long run.
For example, a total of 7 can be made with six different dice combinations, making it the most probable single total. Totals like 2 or 12 have far fewer combinations and therefore show up less frequently. These differences in frequency are why some bets pay more than others: higher payouts compensate for lower probability.
Every roll is independent, which means past results do not change the probability of future rolls. Understanding these probabilities helps explain why specific bets have particular payouts and where value lies on the table. Keep this principle in mind when choosing which wagers to place.
Types of Craps Bets Explained
Craps offers many ways to wager, and each bet has its own rules and expected payout. Knowing the main categories helps you pick bets that align with your preferences and budget.
Below are the most common odds and side bets you will see at the table, explained in straightforward terms.
Pass Line Odds
After a point is set by a Pass Line bet, you may place an odds bet behind it. If the shooter rolls the point before a 7, both bets win. Payouts depend on the point number: 2:1 for 4 or 10, 3:2 for 5 or 9, and 6:5 for 6 or 8. Because these odds match the actual probabilities, they are considered fair bets in mathematical terms.
Tables often cap how much you can place as odds, commonly expressed as multiples of your original Pass Line stake (for example, 2x, 3x, 5x, 10x). Minimum and maximum bet levels vary by casino, so check the table limits before adding large odds. Remember that taking odds increases your exposure as well as your potential return.
Don't Pass Odds
Don’t Pass Odds back the opposite outcome: you win if a 7 appears before the point. The payouts reflect the reversed probabilities: 1:2 for 4 or 10, 2:3 for 5 or 9, and 5:6 for 6 or 8. These are also true-odds payouts and fit into a defensive style of play for those preferring that approach.
Like Pass Line odds, Don’t Pass odds are often limited by the table in multiples of the original bet. Because you are effectively betting against the shooter, this strategy can feel less volatile to some players, though the same house limits and rules apply.
Come and Don't Come Odds
Come and Don’t Come bets function like Pass Line and Don’t Pass bets but can be placed after the initial come-out roll. Once a Come bet establishes its own point, you may add an odds bet to it. The payout structure mirrors the Pass Line and Don’t Pass odds described above.
These bets let you enter the action mid-shoot and are useful for players who want the same true-odds opportunities without waiting for a new come-out roll. As with other odds bets, table maximums and minimums apply, so confirm limits with the dealer.
Place and Buy Bets
Place bets are wagers that a chosen number will appear before a 7. Different numbers offer different payouts, typically reflecting how often they are rolled. Buy bets are similar, but a commission is charged in exchange for true-odds payouts. Both are alternative ways to target specific numbers at the table.
Key points to note:
- Place bets pay odds determined by the number selected; common payouts favour 6 and 8 more than other numbers.
- Buy bets give you true odds but usually carry a commission, often 5% of the potential winnings or sometimes 5% of the stake, depending on house rules.
- Casinos set minimums and maximums for place and buy bets, and the cost versus benefit of the commission should be weighed before choosing a buy bet.
These categories cover the main ways to play odds and number-specific bets in craps; other side bets exist but tend to carry higher house edges and different risk profiles.
What Are the True Odds Versus the Payout Odds in Craps?
True odds are the exact mathematical chances of an outcome based on dice combinations. Payout odds are what the house offers when a bet wins. When payout odds are lower than true odds, the difference provides the casino with its advantage.
Odds bets are notable because their payout odds match true odds, removing that built-in edge for those specific wagers. Most other bets, however, have payout odds set slightly below true odds, which is how the house margin is maintained. Knowing this distinction helps you judge which wagers offer fairer returns and which carry a larger expected cost over time.
House Edge in Craps: What Should You Know?
The house edge is the long-term average advantage the casino holds on each type of bet. In craps, this edge varies significantly between bets. Simple, core wagers such as Pass Line or Don’t Pass typically carry a low house edge, while some proposition and side bets can be much less favourable.
Seeing the house edge as a statistical expectation rather than a short-term outcome makes it easier to plan your play. Choosing bets with smaller edges and using odds bets where available will generally reduce the expected cost of play. Keep betting amounts in proportion to your budget so that volatility does not create undue stress.

Common Myths About Craps Odds Debunked
Craps has its share of misconceptions. Clearing these up helps you focus on meaningful decisions at the table.
One myth is that previous rolls influence future ones. In fact, each roll is independent, and no sequence of past results alters the probability of the next outcome. Another misconception is that specific betting systems can overcome the mathematical odds. Betting patterns may change how quickly you win or lose, but they cannot change the underlying probabilities.
Some players look for patterns or feel they can predict upcoming numbers, yet what appear as sequences are simply random variation. Recognising these points prevents wasted effort on ineffective strategies and keeps attention where it matters: understanding bet structure and managing stakes sensibly.
How to Calculate Your Potential Winnings in Craps
Calculating winnings centres on comparing your stake with the payout ratio for the bet you place. For example, a bet that pays 2:1 returns twice the stake as profit, plus the original stake, while a 3:2 payout returns one and a half times the stake as profit.
To work this out in practice, take the payout ratio and multiply it by the amount you wager to find the profit. Add your original wager to that profit to determine the total return. For instance, a £10 wager on a 3:2 payout yields £15 profit and a £25 total return. For fractional payouts such as 6:5, the same approach applies using the appropriate fraction.
Because different bets use different ratios, checking the table rules before betting ensures you know what a successful outcome will pay. This clarity helps with bankroll planning and sets realistic expectations.

Craps has a specific vocabulary. The short definitions below will help you follow conversations at the table and make informed choices.
Pass Line Bet
A primary bet placed before the come-out roll, predicting the shooter will win by rolling a 7 or 11 immediately, or by making the point before a 7.
Don’t Pass Bet
The opposing main bet, backing an immediate 2 or 3 or a 7 before the point. A roll of 12 is usually a push on the come-out.
Odds Bet
An extra wager placed behind an existing Pass Line or Don’t Pass bet after a point is set. These bets pay true odds.
Come Bet
A bet placed after the come-out roll that establishes its own point and follows the same win and loss rules as a Pass Line bet.
Don’t Come Bet
Made after the come-out roll, this bet mirrors the Don’t Pass bet and can establish a new point against the shooter.
Place Bet
A wager that one of the numbers 4, 5, 6, 8, 9 or 10 will be rolled before a 7. Payouts differ by number.
Buy Bet
Similar to a Place bet but with a commission charged to secure true-odds payouts.
Payout Odds
The ratio used to calculate how much a winning bet pays out.
True Odds
The mathematical probability of an outcome based on the number of dice combinations that produce it.
