Craps
Throw the dice at a full craps table with your medals from the Medal Game Center, then see the exact house edge of every bet — from 0% on the odds to 16.7% on Any Seven.
This table isn’t linked to the floor jackpot: play here doesn’t feed it or win it.
Craps now plays with your medals
This table uses the medals from the Medal Game Center, the same ones every game there plays with. The old 1,000 chips are retired: they are not turned into medals, which are counted on a different scale.

Medals are for playing the games on this site only. They are not money: they cannot be bought, cashed out or exchanged for anything.
These are your medals from the Medal Game Center, shared by every game there. They are reset only at the Medal Game Center. Medal Game Center
COME and DON’T COME are bet once a point is on, as a line bet for the next roll: a number other than 7, 11, 2, 3 or 12 moves the bet to that number, where its own odds can be put on (tap it there). The line’s odds go behind the line bet, on ODDS and LAY.

- Line bets only on the come-out; odds only behind a line bet once the point is ON.
- A spot holds up to 50 medals; the odds go up to 3-4-5× the line bet (lay 6×). A spot marked “in 6s” or the like takes medals in those steps, so a press puts on the BET rounded up to the step.
- Place bets stay up until a 7. Undo and Clear take back only what you put on since the last roll; Take down takes back every bet that may come down.
Two dice give 36 equally likely combinations, so every probability here is an exact fraction. House edge is the average loss per medal bet, per decision (pushes count as decisions).
The 36 combinations
7 is the most common total (6 ways) — which is why it ends every point.

Odds bets pay exactly what they are worth, so their edge is zero — behind a come point too. Come and Don’t Come are Pass and Don’t Pass made once a point is on, with the same edges. The flashier the win in the center, the bigger the edge.
Every win in whole medals
A medal cannot be cut, so a bet that pays a fraction takes medals only in amounts it pays in whole medals, as a dealer asks for 6 on the 6. These are the steps:
| Bet | Pays | Medals at a time |
|---|---|---|
| Place 4 and 10 | 9:5 | 5s |
| Place 5 and 9 | 7:5 | 5s |
| Place 6 and 8 | 7:6 | 6s |
| Pass or Come odds on 4 and 10 | 2:1 | 1s |
| Pass or Come odds on 5 and 9 | 3:2 | 2s |
| Pass or Come odds on 6 and 8 | 6:5 | 5s |
| Lay odds against 4 and 10 | 1:2 | 2s |
| Lay odds against 5 and 9 | 2:3 | 3s |
| Lay odds against 6 and 8 | 5:6 | 6s |
Nothing is ever rounded, so every edge on this page is exactly the edge on the table. A table that rounds a win down instead (5 medals on the 6 winning 5, not 5⅚) would cost the player more than these figures say.
Where 244 / 495 comes from
Pass wins on a come-out 7 or 11, or by making the point before a 7:
| How it is decided | Chance | Makes it | Contributes |
|---|---|---|---|
| Come-out 7 or 11 | 2/9 | 1 | 2/9 |
| Come-out 2, 3, 12 (lose) | 1/9 | 0 | 0 |
| Point 4, then made | 1/12 | 1/3 | 1/36 |
| Point 5, then made | 1/9 | 2/5 | 2/45 |
| Point 6, then made | 5/36 | 5/11 | 25/396 |
| Point 8, then made | 5/36 | 5/11 | 25/396 |
| Point 9, then made | 1/9 | 2/5 | 2/45 |
| Point 10, then made | 1/12 | 1/3 | 1/36 |
| Pass wins | 244/495 = 49.293% |
Taking odds shrinks the edge
The Pass line always costs 7/495 per flat bet, but odds add action at zero edge — so the edge on everything you bet falls as you take more odds.
| Strategy | Edge on total action |
|---|---|
| Pass line only | 1.414%7/495 |
| Pass + 1x odds | 0.848%7/825 |
| Pass + 2x odds | 0.606%1/165 |
| Pass + 3-4-5x odds | 0.374%7/1,870 |
| Pass + 10x odds | 0.184%7/3,795 |
| Pass + 100x odds | 0.021%1/4,785 |
| Don't Pass + 6× lay | 0.273%3/1,100 |
How long does a shooter last?
A hand ends only on a seven-out (a come-out 7 is a winner). From a Markov chain over the come-out and the six points:
In 2009 Patricia Demauro rolled 154 times before sevening out. The chance of a hand lasting that long is about 1 in 5,590,264,072.
FLOOR JACKPOT
This table isn’t linked to the floor jackpot. Its best play already brings back nearly every medal played, so play here neither feeds the floor jackpot nor draws for it. As on a real floor, not every cabinet is on the progressive.
Linked machines: Medal Pusher, Slot Machine, Calico Janken, Roulette & Martingale, Three Card Poker, Big Catch Harbor, Mini Turf Racing, Ball Bingo, Star Festival Big Wheel, High & Low Ladder, Moonlit Sic Bo, Whale Isle Sugoroku, Candy Shop Medal Maze, Video Keno, Hot Spring Smart Ball, Goldfish Lantern Pachinko, Cherry Blossom Carousel, Onsen Shooting Gallery.
The simulations play with medals of their own: your medals are not touched.
Which bet costs the most?
Six players bet the same way on every roll of the same dice. Each line is the house edge they have actually lost on everything they bet; dashed lines are the exact values. Luck dominates early — the order only settles after tens of thousands of rolls.
A night at the table
Many players sit down with the same number of medals and follow one strategy for a number of rolls (5-medal bets; Place 6 & 8 are 6 each). After the last roll an open line bet is played out and everything else is taken down. How many go home ahead?
Shooter hands: simulation vs exact
Roll until each shooter sevens out and count how long every hand lasted. Bars are the simulation; the line is the exact Markov-chain answer.
