Craps Dice Probability Glossary

Essential terminology and concepts for understanding craps, dice probability, betting odds, and professional table etiquette in the world of casino gaming.

Understanding Craps Terminology

Craps is one of the most dynamic and exciting casino dice games, with its own unique vocabulary and mathematical principles. Understanding the terminology is essential for anyone looking to play with confidence and comprehension. This glossary covers the fundamental concepts, betting terms, probability mechanics, and professional conduct expectations at the craps table.

The game revolves around rolling two six-sided dice and predicting outcomes based on probability theory. Each outcome has specific odds and corresponding payouts. Learning the language of the game helps players make informed decisions and appreciate the mathematical elegance underlying craps strategy.

Key Craps Terms & Definitions

Come Out Roll

The initial roll of a craps game that establishes the point. If the shooter rolls a 7 or 11, it's a natural win for pass line bettors. A 2, 3, or 12 is called "craps" and loses pass line bets. Any other number establishes that as the point.

Point

The number established during the come out roll (4, 5, 6, 8, 9, or 10). The shooter must roll this number again before rolling a 7 to win on pass line bets. This phase of the game continues until either the point repeats or a 7 appears.

Pass Line Bet

One of the fundamental wagers in craps. This bet wins on the come out roll with a 7 or 11, loses on 2, 3, or 12, and requires the point to be repeated before a 7 appears. It has a house edge of approximately 1.4 percent.

Don't Pass Bet

The opposite of the pass line bet. This wager wins if 2 or 3 appears on the come out roll, loses on 7 or 11, and pushes (ties) on 12. After the point is established, it wins if a 7 appears before the point repeats, with similar house edge to pass line bets.

Odds Bet

An additional bet made after a point is established with no house edge. This supplementary wager pays true odds on the probability of the point repeating before a 7 appears. It's considered one of the best bets in casino gaming due to its fair payout structure.

Seven Out

When the shooter rolls a 7 during the point phase of the game. This ends the shooter's turn and typically loses pass line bets. The term "seven out" marks a significant shift in game momentum and betting outcomes.

Probability & Odds Concepts

Dice Probability Mathematics

Understanding the mathematical foundation of craps is crucial for serious players. Each combination of two dice has a specific probability. A seven can be rolled in six different ways (1-6, 2-5, 3-4, 4-3, 5-2, 6-1) out of thirty-six possible combinations, making it the most likely outcome with a probability of approximately 16.67 percent.

Other numbers have varying probabilities: six and eight can each be rolled in five ways (13.89%), five and nine in four ways (11.11%), four and ten in three ways (8.33%), and two and twelve in only one way each (2.78%). These probabilities form the mathematical basis for true odds payouts on craps bets.

The importance of understanding these probabilities cannot be overstated—they determine which bets offer better value and which carry higher house edges. Players who grasp these concepts make more informed decisions about their wagering strategy.

Table Etiquette & Professional Conduct

Craps Table Standards

Craps has established conventions that all players should respect. Never touch the dice with two hands simultaneously, and always throw them with enough force to reach the back wall—this ensures randomness and maintains game integrity. Never call out numbers while dice are in flight, and refrain from making negative comments about other players' luck.

Proper handling of chips, respectful communication with dealers and other players, and understanding your role at the table are essential components of professional craps play. Learning these standards ensures a positive experience for everyone at the table and maintains the game's integrity.

Additional Glossary Terms

Snake Eyes

A roll of two ones (1-1), totaling 2. This is the lowest possible roll and typically results in a loss for pass line bettors on the come out roll.

Boxcars

A roll of two sixes (6-6), totaling 12. Along with snake eyes, this is a losing roll for pass line bets on the come out roll.

Yo-Leven

Craps terminology for rolling an 11 (two fives or a five and six). This is a winning roll for pass line bettors on the come out roll and is called "yo" to distinguish it from "seven" in noisy casino environments.

Craps Number

Any roll of 2, 3, or 12 on the come out roll. These rolls result in immediate losses for pass line bettors and are called "craps" due to the game's historical origins.
