Online craps remains one of the most exciting yet strategically complex casino games, largely due to its reliance on probabilities and odds. Players who understand the mathematical underpinnings of the game can make smarter bets, improve their chances of winning, and better manage their bankrolls. This article explores how odds influence player strategies by examining the likelihood of common outcomes and explaining different payout structures in online craps games.

Calculating the Likelihood of Common Roll Outcomes

Probability of Rolling a Natural (7 or 11) on the Come-Out Roll

The initial step in a craps round involves the come-out roll, where players hope for a quick win with a natural — either a 7 or 11. To understand the odds, consider the total possible combinations when rolling two six-sided dice, which is 36.

• Rolling a 7: There are six combinations — (1,6), (2,5), (3,4), (4,3), (5,2), (6,1). So, the probability is 6/36, or approximately 16.67%.
• Rolling an 11: There are two combinations — (5,6) and (6,5). The probability is 2/36, or about 5.56%.

Combining these, the probability of rolling a natural (7 or 11) is influenced by the rules of the game, which can vary across different platforms.

Probability of natural on come-out: 8/36 = 22.22%

This relatively high likelihood explains why natural wins are common at the start of rounds and form the foundation for many strategy decisions.

Chance of Establishing a Point and Its Impact on Betting

If the come-out roll results in any number other than a 2, 3, 7, 11, or 12, the game transitions into the point phase, where players aim to roll their previously established point number again before rolling a 7.

• Numbers that establish a point include 4, 5, 6, 8, 9, and 10.
• Each point has a specific probability based on the number of combinations that yield it:

The overall chance of establishing a specific point depends on the initial roll, but the combined probability provides insights into how often certain points occur in long-term play. For example, the 6 or 8 are the most commonly established points, making strategies around them particularly impactful.

Understanding these probabilities influences decision-making, especially in bets like the “odds bet,” which pays true odds and depends on the likelihood of hitting the point before a 7.

Assessing the Odds of Craps (2, 3, or 12) and Their Consequences

Rolling a 2, 3, or 12 on the come-out roll results in an immediate loss for Pass Line bets — these are known as “craps.” Their probabilities are:

• 2 (Snake Eyes): 1/36 (~2.78%)
• 3 (Ace Deuce): 2/36 (~5.56%)
• 12 (Boxcars): 1/36 (~2.78%)

Combined, the chance of rolling any craps on the come-out is approximately 10.92%. Recognizing these odds helps players understand why, statistically, the house has a built-in advantage for certain bets and why some bets are considered riskier than others.

For example, the low probability of craps makes bets on these outcomes less favorable for the player, especially considering their payoffs are often less than the true odds, leading to a house edge.

Deciphering Payout Structures for Different Bet Types

Standard Pass Line and Don’t Pass Bets: Payout Ratios Explained

The most fundamental bets in craps are the Pass Line and Don’t Pass bets, which are straightforward and typically offer the lowest house edge:

• Pass Line Bet: Wins if the shooter rolls a natural (7 or 11) on come-out, pays even money (1:1).
• Don’t Pass Bet: Wins if the come-out roll is 2 or 3, and pushes on 12 (depending on casino rules). It wins if a 2 or 3 appears, or if a 7 is rolled before the point is established, generally paying even money.

In terms of probabilities, the house edge is approximately 1.41% for Pass Line bets and about 1.36% for Don’t Pass bets, due to the distribution of winning outcomes versus payouts.

Odds Bets and Their True Odds Versus Payouts

One of the most attractive aspects of craps is the availability of “odds bets,” which are placed in conjunction with Pass Line or Don’t Pass bets. These bets pay true odds, meaning they have no house edge—if placed correctly.

Casinos often offer less than these true odds as payouts for these bets, creating a built-in advantage for the house. For example, a “6 or 8” odds bet might pay only 6 to 5, whereas the true odds are 6 to 5, effectively reducing the house edge to near zero for this wager. This discrepancy is a key consideration for strategic players aiming to maximize their winning potential.

“Understanding the true odds and their payouts is essential for effective betting in craps, especially when leveraging odds bets to minimize house advantage.”

Side Bets and Variation in Payouts Based on Probabilities

Apart from the standard bets, many online craps platforms offer side bets, such as “Hardways,” “Any Craps,” or “Horn” bets. These bets often have higher payout ratios but are less favorable from a probability standpoint.

• Hardways Bets: Betting that 4, 6, 8, or 10 will be rolled as doubles before the easy ways or a 7. The payouts range from 7:1 to 9:1, reflecting their lower probability.
• Any Craps Bet: Wins if the outcome is 2, 3, or 12; typically pays 7:1, but the probability is around 11%. Hence, house edge remains high.
• Horn or Phrase Bets: Involve multiple numbers with higher payouts but correspondingly lower probabilities, increasing the house advantage substantially.

Understanding the probability behind these side bets enables players to make informed decisions—either to capitalize on the higher payouts with calculated risk or to avoid unfavorable bets that skew the house edge significantly.

Conclusion

In online craps, a firm grasp of probabilities and payout structures empowers players to develop more effective strategies. Recognizing the likelihood of common outcomes like natural wins, points, or craps informs better betting choices, especially in leveraging true odds and minimizing the house edge. As in all casino games, knowledge of the mathematical fundamentals is the key to consistent success and responsible gambling.
