Rock Paper Scissors against the house is a streak game. Each win multiplies your stake, a draw keeps the streak alive, a loss ends it at zero. You can cash out after any win.
The payout
Each win multiplies by 1.97, so after n wins the multiplier is 1.97ⁿ (rounded down). The 1.97 comes from 2 − 3 × edge with a 1% edge: three outcomes, one of which is a push, so the edge is spread a little differently than in a two-outcome game.
| Wins in a row | Multiplier |
|---|---|
| 1 | 1.97× |
| 2 | 3.88× |
| 3 | 7.64× |
| 5 | 29.66× |
| 8 | 226.7× |
Each throw is a third win, a third draw, a third loss. Draws cost nothing and change nothing; only losses end the run. RTP works out to about 98.5%.
Cash-out logic
Because every throw has the same one-in-three chance of ending the run, the expected value of continuing is the same at every step; what changes is how much you have on the table. A common rule that keeps sessions sane: pick a target number of wins before the first throw (two or three is typical), cash out when you hit it, and never extend a run in the moment.
Demo versus real
The browser demo uses a 4% edge (1.88 per win). Logged-in play uses 1.97. If you are checking numbers, use the logged-in table above.
Limits and verification
