How to play craps: the rules

Craps is a dice game: you bet on what two dice will total. The basic bet is the pass line. On the first roll, 7 or 11 wins and 2, 3 or 12 loses; any other number becomes the point, and then you win if the point rolls again before a 7.

The two phases

A round has two phases. It starts with the come-out roll, while the puck, the marker on the table, says OFF. If that roll sets a point, the puck turns ON and the shooter keeps rolling until the point or a 7 comes up.

RollOn the come-outWith a point on
7Pass line wins (a natural)Pass line loses (seven-out)
11Pass line wins (a natural)No decision
2, 3 or 12Pass line loses (craps)No decision
4, 5, 6, 8, 9 or 10Becomes the pointPass line wins if it’s the point. Any other number is no decision.

The 7 does opposite things: it wins on the come-out and loses once a point is on. That’s the first thing to remember.

How a round goes

  1. Before the come-out, put your chips on the pass line. The puck says OFF.
  2. The shooter rolls two dice. A 7 or 11 is a natural: the pass line wins 1 to 1, and the next roll is a new come-out.
  3. A 2, 3 or 12 is craps: the pass line loses, and the next roll is a new come-out.
  4. A 4, 5, 6, 8, 9 or 10 becomes the point. The puck turns ON and sits on that number. Your bet stays up, and you can now add odds behind it.
  5. The shooter keeps rolling. For the pass line, only the point and the 7 matter. Every other number, 11 and craps included, is no decision.
  6. If the point rolls first, the pass line wins 1 to 1, the puck goes OFF, and the same shooter starts a new come-out.
  7. If a 7 rolls first, that’s a seven-out: pass line bets and their odds lose, the round ends, and the dice go to the next shooter.

A 7 on the come-out is not a seven-out: the pass line wins and the shooter keeps the dice. In our game there are no other players waiting for the dice, so you roll every time.

How many ways each total can be rolled

Two dice can land 36 ways, all equally likely, and most totals can be made more than one way. This table explains everything else in the game.

104-6, 5-538.33%
115-625.56%
126-612.78%

Each pair of different numbers counts twice: 3-4 and 4-3 are different rolls, which is easy to see with one red die and one blue.

On the come-out, 8 ways win for the pass line and 4 lose, so it starts ahead. But once a point is on, the 7 is the most common total, with 6 ways against 5 at most for any point, so the 7 usually comes first. The two parts almost cancel out: the pass line wins 49.29% of the time and loses 50.71%.

The main bets

The house edge is what a bet costs on average, as a share of the bet: 1.41% on the pass line means about 1.41 chips lost for every 100 bet, in the long run. These are exact numbers, not simulated.

With the game’s default rules: the field pays triple on 12 (5.56% if it pays double). A 12 on the first roll of a don’t pass or don’t come bet is a tie. Place bets, hardways and the odds on come bets are normally off on the come-out roll. Pass and come bets with a point can’t be taken down, but their odds can.

Come and don’t come are line bets you can make with a point already on. The next roll works as their own come-out, and a 4, 5, 6, 8, 9 or 10 becomes that bet’s number. That’s why the same 7 can win a new come bet and lose an older one.

The table also has buy and lay bets, big 6 and 8, and hop bets. The odds page has them all.

The odds bet

Once a point is on, you can add odds behind your pass line or come bet. It’s the only bet in the game with no house edge, because it pays exactly what its chance of winning is worth. There are 3 ways to roll a 4 and 6 ways to roll a 7, so the 7 comes first twice as often, and odds on the 4 pay 2 to 1.

PointWays vs. the 7Comes before a 7Odds payMost odds at 3-4-5x
4 or 103 vs. 633.33%2:13x
5 or 94 vs. 640.00%3:24x
6 or 85 vs. 645.45%6:55x

On don’t pass and don’t come you lay the odds instead: you put up more to win less, at 1:2 (4, 10), 2:3 (5, 9), 5:6 (6, 8). That has no house edge either. Our table starts at 3-4-5x odds, and you can change that in the table rules.

An example at 3-4-5x: with 10 chips on the pass line and a point of 6, you can take up to 50 in odds. If the 6 comes first, the line pays 10 and the odds pay 60. If a 7 comes first, you lose both.

Odds don’t change what you lose on average: 0.14 chips per 10-chip pass line bet, with or without them. What changes is the total at stake, 37.78 chips on average at 3-4-5x, so the edge on all your money falls from 1.41% to 0.37%. The catch is bigger swings: a seven-out now costs several times your line bet.

Which bets to make and which to leave alone

Keep your chips on the line bets and their odds, and add place 6 or 8 if you want more numbers working. Those are the cheapest bets on the table.

Bets to makeHouse edgeWhy
Don’t pass or don’t come, with odds0.273%The lowest edge on the table, at 3-4-5x. You lay more to win less, so it ties up more chips.
Pass line or come, with odds0.374%The simplest good bet, at 3-4-5x. Learn this one first.
Don’t pass or pass line, no odds1.36%, 1.41%Still cheap, with smaller swings.
Place 6 or 81.52%Almost as cheap, you pick the numbers, and you can take it down at any time.

Everything else costs more, and the price climbs fast. Big payouts make these bets look good, but they still pay less than the chance of winning is worth.

Bets to leave aloneHouse edgeWhy
