Fundamentals of Craps: Dice, Bets, and Table Layout
Craps is a dice game based on the roll of two six-sided dice, and understanding the physical mechanics of the dice, the types of bets available, and the layout of the table is the first step to making informed decisions. Each die has faces 1–6, so there are 36 equally likely combinations of two dice. The most common totals are 7 (6 combinations) and 6 and 8 (5 combinations each). The game progresses through short rounds: a "come-out" roll establishes a point (4, 5, 6, 8, 9, or 10) or results in an immediate win/loss (7 or 11 wins on the pass line; 2, 3, 12 are craps on the pass line). Once a point is set, the shooter keeps rolling until they either roll the point again (a win for pass line bettors) or roll a 7 (a loss for pass line bettors), which is called "seven-out."
The table layout is designed to accommodate multiple bet types simultaneously. The pass line and don't pass line run along the perimeter for the simplest bets; the come and don't come areas mirror those bets during established points. Center areas host proposition bets, field bets, and place/buy/sell options, each with unique payouts and house edges. Understanding where to place chips for each bet and how to read the table keeps you from accidentally making an unfavorable wager.
Craps also allows "odds" bets placed behind the pass/come or don't pass/don't come bets once a point exists. These odds bets pay true odds (no house edge) because casinos do not mark them up, making them one of the most favorable wagers. The interplay of base bets and true odds is fundamental to evaluating expected value. For a practical player, mastering these core mechanics — dice probabilities, roll sequences, table geography, and basic bet flow — dramatically improves both enjoyment and judgment while playing.
House Edge and Player Odds: How Probability Affects Payouts
Understanding house edge and true odds is essential to knowing what to expect over time in craps. The house edge is the average percentage of each bet that the casino expects to keep in the long run. It varies widely by bet type: pass line has about a 1.41% house edge, don't pass is roughly 1.36%, and some place bets (like placing a 6 or 8) have lower house edges around 1.52% when done as place bets, but buy bets can reduce the house edge further if you pay a commission. In contrast, many proposition bets (hardways, single-roll bets, Yo/Any 7) carry very high house edges, sometimes exceeding 10% or 16%, which makes them risky long-term.
True odds refer to the mathematical ratio of winning combinations to losing combinations for a particular outcome, without house markup. For instance, the true odds of rolling a 4 before a 7 (when 4 is the point) are 3:6, or 2:1 against hitting the 4 first. Casinos often pay less than true odds on many bets, creating the house edge. However, the "odds" bets taken behind a pass or come bet are paid at true odds by most casinos (e.g., 2:1 on a point of 4 or 10), so adding odds to a pass line bet reduces the combined house edge toward zero as the odds portion has no edge.
Probability also informs variance—the dispersion of outcomes around the expected value. High-house-edge bets often come with high variance and more frequent large swings, while low-house-edge bets produce steadier, slower losses on average. Expected value (EV) of a bet equals (probability of win × payout) minus (probability of loss × stake), and over many rolls EV predicts the average per-bet return. For players who want longevity at the table, selecting bets with low house edges and adding full or allowed odds where affordable is the statistically sound approach.
Common Bets Explained: Pass Line, Come, Place, and Proposition Bets
The most common, foundational bets in craps include the pass line, don't pass, come, and don't come, along with place bets and various proposition bets. The pass line is the simplest and most popular: on the come-out roll, a 7 or 11 wins, and 2, 3, 12 lose (12 is a push on some tables depending on rules). If a point is set, the pass line wins if the point is rolled again before a 7. The don't pass is the opposite: a 2 or 3 wins on the come-out, 7 or 11 lose, and 12 pushes in most U.S. casinos; after a point, it wins if a 7 is rolled before the point. Come and don't come bets work like pass/don't pass but are placed after a point is established, creating a new point tied to that bet.
Place bets are wagers on specific numbers (4, 5, 6, 8, 9, 10) to be rolled before a 7. Payouts differ by number; for example, placing a 6 or 8 typically pays 7:6, while placing a 4 or 10 pays 9:5. Buy bets are similar to place bets but pay true odds minus a commission (vigorish), which can be advantageous for some numbers depending on the commission structure. Sell bets let players bet against a number (like betting the 7 will come before the number), often used in conjunction with don't bets.
Proposition bets include one-roll bets (any 7, any craps, specific doubles) and hardways (betting a pair such as double 4 to hit before a 7 or the corresponding easy combination). These bets are attractive because they can pay large odds quickly, but they typically carry poor expected value relative to pass/come or place bets; for instance, a hard 6 (double 3) pays 9:1 but has a house edge over 9%. Field bets are single-roll or next-roll bets for certain totals, with varying payouts for 2 and 12. Each bet type serves different player goals—some for steady play and low edge, others for quick, high-payout volatility—so selecting a mix aligned with bankroll and risk tolerance is key.
Betting Strategies and Bankroll Management: Practical Tips for Players
Craps strategies often focus on minimizing house edge and managing bankroll rather than chasing guaranteed wins. A widely endorsed approach is to stick to pass/come bets with maximum allowable odds. Because odds bets have no house edge, adding them to low-edge base bets brings your overall expected loss rate down. For example, a pass line bet with full 3-4-5x odds (depending on table limits) will have a much lower combined house edge than the pass line alone. Avoid high-house-edge proposition bets if your goal is to maximize expected playtime and minimize long-term losses.
Bankroll management is essential: set a session budget and determine bet sizing so you can weather variance. A common rule is to risk only 1–2% of your total bankroll on any single base bet (not including odds), which buffers against short-term swings and extends play. Be aware of table limits: minimums can force higher relative risk for small bankrolls, and aggressive progression systems (martingale, parlay, Fibonacci) do not change the underlying negative expected value and can lead to rapid ruin if you hit the table limit or run out of funds.
Table etiquette and practical tips also influence a good experience: respect dealers and other players, place chips on clearly defined betting areas, and ask dealers if unsure about rules or payouts. Learn the payout vs. true odds for buy/place bets and understand commission mechanics for buy bets—sometimes paying the commission up-front is worth it for reduced house edge on 4/10. Finally, approach the game with predefined limits for losses and time, and consider viewing gambling as entertainment with a built-in cost rather than a money-making endeavor. Responsible play, combined with mathematically sound bet selection (pass/come with odds, selective place/buy), gives you the best chance to enjoy craps with controlled risk.
