Craps simulator
Roll the dice on a full craps table with play chips, watch the puck and see which bets cost you the least.
The simulator needs JavaScript. The rules, payouts and house edge are below.
Play one round in four steps
- Pick a chip and tap Pass Line.
- Press Roll – this first roll is the come-out. Seven or eleven wins; two, three or twelve loses.
- Any other total (four, five, six, eight, nine or ten) becomes the point.
- Keep rolling: the point before a seven wins, a seven first loses (seven-out).
Example: come-out six → the point is six. Rolls eight, five, six → Pass wins. Full rules: craps rules.

House edge per bet decided (pushes not counted), exact math from the dice.
OFF (black side): the next roll is a come-out. ON (white side) sits on the point number, for example ON at nine.
When the puck is ON, the Odds spot appears behind your Pass bet. Place bets and hardways stay off on the come-out unless you turn them on.
Cheapest bets: Pass Line plus odds
- Pass Line: house edge 1.41%.
- Don't Pass: 1.36% – a twelve on the come-out is a push (barred).
- Odds: pays true odds, no house edge – 2 to 1 on four and ten, 3 to 2 on five and nine, 6 to 5 on six and eight.
- Pass plus three, four and five times odds: 0.37% on all money in play – lower with bigger odds, for example 0.18% with ten times odds.
Put your Pass bet down first, then add odds as soon as the puck turns ON.
Most expensive bets: the center
Most center bets are one-roll bets: they win or lose on the very next roll. A seven comes up 6 ways out of thirty-six, yet Any Seven costs 16.67%.
- Horn: 12.50%
- Aces or Twelve: 13.89%
- Any Craps, Yo Eleven: 11.11%
- Hard Four or Hard Ten: 11.11% – not a one-roll bet: it stays up until the hard number, the easy number or a seven is rolled.

What the session stats mean
- Rolls: how many times you rolled.
- Total bet: all chips you put down, counted every time.
- Net result: chips won minus chips lost.
- Result per total bet: over many rolls it tends to move toward the house edge of your bets.
Play a few hundred rolls with only center bets, then only Pass plus odds, and compare the result per total bet.

Questions
Is this craps simulator free?
Yes. You play with play chips only, there is nothing to buy and no sign-up.
What is the best bet in craps?
Pass Line with odds costs the least: Pass alone has a house edge of 1.41%, and with three, four and five times odds the edge on all money in play drops to 0.37% – lower with bigger odds, for example 0.18% with ten times odds. Don't Pass is close at 1.36%.
What does seven-out mean in craps?
After a point is set, rolling a seven before the point is a seven-out. Pass bets lose and a new come-out roll starts.
Is there a craps strategy that wins over time?
No. Every bet except odds has a house edge, and no betting pattern changes it, so over time the house edge wins.
Why is Any Seven a bad bet?
It pays less than the true chance of rolling a seven, so its house edge is 16.67% – one of the highest on the table.
