Craps is a modern casino game built around two dice, a come-out roll and a point cycle. Its terminology reflects a long history of dice games, but current value is determined by the exact table rules and payout schedule. The central wagers are relatively straightforward once the two phases are separated; many proposition bets are much more expensive because their payouts fall well below fair odds.
History explains the language, not the next roll. Dice games existed long before modern casinos, and craps is commonly linked to the English game hazard and later American adaptations. Historical accounts differ on precise transmission and naming, so broad lineage is safer than one definitive invention story.
Terms such as shooter, point, come and don't come developed with casino procedure. They do not imply that a shooter can create a personal probability pattern. GambleRoad's gambling history timeline places dice games within the wider development of regulated wagering.
| Two-dice total | Combinations | Probability | Come-out effect on Pass |
|---|---|---|---|
| 2 | 1 | 2.78% | Lose |
| 3 | 2 | 5.56% | Lose |
| 7 | 6 | 16.67% | Win |
| 11 | 2 | 5.56% | Win |
| 12 | 1 | 2.78% | Lose |
| 4, 5, 6, 8, 9, 10 | 24 combined | 66.67% | Establish point |
The come-out roll starts the contract
On the Pass Line, 7 or 11 wins immediately and 2, 3 or 12 loses. Any of 4, 5, 6, 8, 9 or 10 becomes the point. The shooter then rolls until the point repeats, winning the Pass wager, or 7 appears, losing it.
The point phase changes the relevant race. If the point is 4, there are three combinations for 4 and six for 7, so 7 is twice as likely to occur first. The even-money Pass payout is supported by the favourable come-out outcomes that preceded that phase.
Don't Pass reverses most outcomes but bars 12
Don't Pass generally loses on come-out 7 or 11, wins on 2 or 3 and pushes on 12. After a point is established, it wins if 7 appears before the point. The bar-12 push prevents the wager from becoming a fair opposite of Pass and creates a small house edge.
Some tables use a different barred number under local rules. Read the layout. Do not assume that “betting against the shooter” changes the dice; it simply selects the opposite side of the settlement contract.
Odds bets pay according to the point ratio
After a Pass point is established, a player may be allowed to take odds. Common true-odds payouts are 2 to 1 on points 4 and 10, 3 to 2 on 5 and 9, and 6 to 5 on 6 and 8. Because those payouts match the combination ratios, the odds portion has no built-in house edge under standard rules.
The original Pass wager still has an edge, so combining it with odds lowers the blended percentage on total action rather than making the whole position positive. Limits such as single, double, 3-4-5 or higher odds determine how much can be added.
Come and Don't Come create later point contracts
A Come wager behaves like Pass using the next roll as its own come-out. If a number becomes its come point, that contract stays on the number while the main table point may differ. Several come bets can therefore exist at once.
Don't Come follows the opposing structure with the applicable barred number. Track each wager separately because a table seven can settle the main line and several come contracts in different directions.
Place bets use fixed payouts below fair odds
A Place 6 commonly pays 7 to 6. Six has five combinations and 7 has six, so fair net odds would be 6 to 5. The lower posted payout creates the edge. Place 5, 9, 4 and 10 use other schedules and should be calculated individually.
Buy and lay bets may use a commission. Whether the commission is charged on the amount wagered or only on wins changes effective value. GambleRoad's online craps variants guide explains why electronic interfaces still require version-specific payout checks.
Proposition bets concentrate a high price in one roll
One-roll wagers on totals, hardways and combinations can offer large-looking payouts. Compare each with the number of winning dice combinations. A total of 2 has one winning combination out of 36; a net payout of 30 to 1 is below fair odds of 35 to 1.
High variance can make these bets memorable, but frequency does not change expected value. A sequence of hardways does not make another hardway more likely. GambleRoad's article on craps techniques and limits should be read as procedural guidance, not a promise that a betting system can alter dice probabilities.
Current rules define rolls, voids and handling
The Massachusetts Gaming Commission lists active approved table-game rules, including Craps and Mini Craps. Formal rules cover valid throws, dice leaving the table, dealer responsibilities, payout procedures and irregularities. Online and automated versions replace some physical procedures with software but should disclose equivalent settlement rules.
A roll can be void under specified conditions. The correct response is to follow the posted procedure, not infer manipulation from an unusual bounce or dealer call. Record the event and request a review when the visible outcome and account settlement differ.
Dice control claims need stronger evidence
Physical throwing style can affect whether a roll is valid, but proving a sustained change in two-dice probabilities requires controlled, large-sample evidence. Casino tables use back walls, pyramids and procedures intended to produce random bounces. Short practice sessions and selected videos do not establish an edge.
Even a small claimed bias must be tested against all totals, table conditions and the cost of invalid or disputed throws. Do not increase stakes because a shooter appears hot. Independent random variation naturally creates long hands and quick seven-outs.
Blended house edge can be misleading when odds are included. A player staking $10 Pass plus $50 odds has most money on a zero-edge component, so the edge as a percentage of total action is lower than on the $10 line wager alone. Expected loss in dollars remains tied to the line wager. State both measures to avoid implying that larger odds reduce the casino's expected dollars from the original bet.
Table maximums can apply differently to flat bets and odds. A posted $5,000 maximum may not permit the theoretical odds multiple on a large line stake. Confirm the base limit, odds limit and whether winnings count toward aggregate payout caps before assuming a strategy can scale.
Online interfaces should show which wagers are working on a come-out roll. Some place and come odds can be turned off by default, while contract bets remain active. A player's preferred setting should be verified after every table change rather than inferred from a previous game.
A craps table checklist
- Separate come-out and point-phase settlement.
- Confirm the barred number on Don't Pass and Don't Come.
- Read the allowed odds multiple and exact payouts.
- Calculate Place, Buy, Lay and proposition bets separately.
- Include commissions in the effective return.
- Review void-roll and dice-handling rules.
- Set total table exposure before adding multiple contracts.
Craps becomes less intimidating when every wager is treated as a probability contract. History explains the vocabulary; the two-dice combinations and posted rules explain the cost.
