Detailed Explanations
Dice Roll Total: This column represents the sum of the two dice rolled in a game of craps. The possible totals range from 2 (1+1) to 12 (6+6). Each total has a different probability of occurring.
Probability (as a Fraction): This column displays the probability of rolling a specific total as a fraction. The numerator represents the number of combinations that result in that total, and the denominator (36) represents the total number of possible combinations when rolling two dice (6 sides on each die, so 6*6 = 36 possible combinations). For example, there’s only one way to roll a 2 (1+1), so the probability is 1/36. There are six ways to roll a 7 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1), so the probability is 6/36.
Probability (as a Percentage): This column expresses the probability of rolling a specific total as a percentage. It’s simply the fractional probability converted to a percentage (fraction * 100). This format is often easier for players to quickly grasp the likelihood of a specific roll. For example, the probability of rolling a 7 is 16.67%, making it the most likely single total to be rolled.
Understanding the Distribution
The probabilities are not uniform. Totals closer to 7 are more likely to occur because there are more combinations of dice that result in these totals. The further away from 7 a total is, the fewer combinations result in that total, and the lower the probability. This creates a bell-shaped distribution curve.
Common Craps Terms and Their Impact on Odds
Understanding the odds of individual rolls is essential, but knowing how they relate to common craps bets is equally important. Here’s a look at some of the most popular bets and how the dice roll odds influence them:
-
Pass Line Bet: This is the most fundamental bet in craps, placed before the come-out roll (the first roll of a new round).
- Wins if the come-out roll is a 7 or 11.
- Loses if the come-out roll is a 2, 3, or 12 (Craps).
- If the come-out roll is 4, 5, 6, 8, 9, or 10, that number becomes the "point." The shooter then continues to roll until either the point is rolled again (Pass Line wins) or a 7 is rolled (Pass Line loses).
- The house edge on the Pass Line bet is approximately 1.41%.
-
Don’t Pass Line Bet: This is the opposite of the Pass Line bet.
- Wins if the come-out roll is a 2 or 3.
- Loses if the come-out roll is a 7 or 11.
- Pushes (no win or loss) if the come-out roll is a 12 (some casinos may treat 12 as a win for the Don’t Pass).
- If the come-out roll is 4, 5, 6, 8, 9, or 10, that number becomes the point. The shooter then continues to roll until either a 7 is rolled (Don’t Pass wins) or the point is rolled again (Don’t Pass loses).
- The house edge on the Don’t Pass Line bet is approximately 1.36%, slightly lower than the Pass Line.
-
Come Bet: This bet is similar to the Pass Line bet but is placed after a point has already been established. The next roll becomes the "come-out roll" for the Come bet. The same rules apply as the Pass Line bet, but with the Come bet having its own point number.
-
Don’t Come Bet: This is the opposite of the Come bet and is placed after a point has been established. The next roll becomes the "come-out roll" for the Don’t Come bet. The same rules apply as the Don’t Pass bet, but with the Don’t Come bet having its own point number.
-
Place Bets: These bets are placed on specific numbers (4, 5, 6, 8, 9, or 10) after a point has been established. You’re betting that the chosen number will be rolled before a 7.
- The payout odds vary depending on the number you’re betting on, reflecting the probability of rolling that number versus rolling a 7. For example, the payout for placing a bet on 6 or 8 is typically 7 to 6, while the payout for placing a bet on 4 or 10 is typically 9 to 5.
- The house edge varies for each place bet, making some more favorable than others.
-
Proposition Bets (e.g., Any 7, Any Craps, 2 or 12): These are single-roll bets, meaning they are resolved on the very next roll of the dice.
- These bets offer high payouts but also have a very high house edge, making them generally unfavorable for players.
- For example, the "Any 7" bet (betting that the next roll will be a 7) typically pays out 4 to 1, but the true odds of rolling a 7 are 5 to 1, giving the house a significant advantage.
- Similarly, betting on 2 or 12 (paying 30 to 1) has a significantly lower probability than the payout suggests, giving the house a high edge.
House Edge and Expected Value
The house edge is the percentage of each bet that the casino expects to win in the long run. It’s important to understand the house edge of different bets to make informed decisions about where to place your money. Bets with a lower house edge offer better odds for the player.
Expected value (EV) is a statistical concept that represents the average amount of money you can expect to win or lose per bet in the long run. It’s calculated by multiplying the probability of each outcome by its corresponding payout and then summing the results. A negative EV indicates that you are expected to lose money in the long run, while a positive EV indicates that you are expected to win money. However, it’s important to remember that EV is a long-term average, and short-term results can vary significantly.
Strategies Based on Odds
While craps is ultimately a game of chance, understanding the odds can help you develop a more strategic approach:
- Stick to Low House Edge Bets: Focus on bets with the lowest house edge, such as the Pass Line/Don’t Pass Line and Come/Don’t Come bets. These offer the best long-term odds for the player.
- Consider Laying Odds: After a point has been established on the Pass Line or Come bet, you can "lay odds" behind the line. This is a side bet that pays out at true odds (no house edge). Laying odds significantly reduces the overall house edge on your Pass Line or Come bet. However, laying odds requires a larger upfront investment.
- Avoid Proposition Bets: While the high payouts of proposition bets may be tempting, the very high house edge makes them a poor choice for long-term play.
- Manage Your Bankroll: Set a budget for your craps session and stick to it. Avoid chasing losses and be prepared to walk away when you reach your predetermined limit.
The Importance of Sample Size
It’s crucial to remember that the probabilities and house edges discussed above are based on long-term averages. In the short term, anything can happen. You might experience winning streaks or losing streaks that deviate significantly from the expected probabilities. The larger the sample size (the number of rolls or the number of craps sessions you play), the closer your actual results will likely be to the theoretical probabilities.
