02The game
How it plays, and where it fits.
The game
- What the player does
- A stack of casino chips grows off a felt table as a shared multiplier climbs. Each player cashes out when they choose, by hand or at an auto target; when the stack topples, any bet still in is lost.
- Why players come back
- Everyone decides when to stop on the same climb and the room sees who held on. The stack is as likely to fall at 50x as at 2x, and the rules say so.
- Round structure
- Shared timed round. 7 s to bet, then the multiplier climbs until the round ends; each player cashes out by hand or at an auto target before it does.
- Session fit
- Quick or long sessions. Social: the whole room plays the same round. Timed rounds.
- Stakes in this build
- 1 to 100 demo credits. Whole credits, 1 to 100 per bet, up to two bets per round.

03The maths
Every number, from the code.
| Mode | RTP | House edge | Hit rate | Net win | Volatility (SD) | Max win | GGR / 1,000 rounds |
|---|---|---|---|---|---|---|---|
| Auto cash-out at 1.50x | 97.00% | 3.00% | 64.67% | 64.67% | Low (0.72) | 1.50× | 30.00 |
| Auto cash-out at 2.00x headline | 97.00% | 3.00% | 48.50% | 48.50% | Low (1.00) | 2.00× | 30.00 |
| Auto cash-out at 10.00x | 97.00% | 3.00% | 9.70% | 9.70% | Medium (2.96) | 10.00× | 30.00 |
| Auto cash-out at 100.00x | 97.00% | 3.00% | 0.97% | 0.97% | High (9.80) | 100.00× | 30.00 |
| Hold to the 10,000x cap | 97.00% | 3.00% | 0.01% | 0.01% | Very high (98.48) | 10,000× | 30.00 |
Crash odds
One shared round for the whole room. The multiplier climbs as e0.12t (2× at 5.8 s, 10× at 19.2 s, 100× at 38.4 s) and the round ends at its crash point, fixed before betting opens. A cash-out at any target k pays k times the stake with probability RTP / k, so every target, manual or automatic, returns the room’s RTP to within 2.3 × 10−12. The chance the round ends in the next second is 11.3% at every height: nothing about the climb predicts the end.
| Room RTP | Ends at 1.00× | Reaches 2.00× | Reaches 10.00× | Reaches 100.00× | Reaches 1,000× | Reaches 10,000× |
|---|---|---|---|---|---|---|
| 96% | 4% | 48.0% | 9.6% | 0.960% | 0.0960% | 0.0096% |
| 97% default | 3% | 48.5% | 9.7% | 0.970% | 0.0970% | 0.0097% |
| 98% | 2% | 49.0% | 9.8% | 0.980% | 0.0980% | 0.0098% |
The house edge comes only from rounds that end at 1.00× before anyone can cash out (3% at the default 97%). A round that reaches the 10,000× cap pays the cap on every bet still in; 1,000× and 5,000× caps are built too and leave the RTP unchanged. Auto cash-out targets run from 1.01× to the cap and pay exactly their target. RTP and cap are per room, so every player in a round sees the same result; this build runs Topple, Snip, Crash and Updraft in one room. In a 10 billion round simulation at 97%, all 21 strategies tested, including two bets, half cash-outs and doubling after a loss, had a 95% interval containing 97%.
Pace
18.6 s a round, about 194 rounds an hour (range 10.5 s to 88.8 s). Server round clock: 7 s betting, the climb (expected 8.1 s from the exact crash distribution; 0 s for an instant end, 76.8 s to the cap), then 3.5 s with the result (5 s after the cap).
GGR / 1,000 rounds is the theoretical gross gaming revenue from 1,000 rounds at a total stake of 1.00: house edge × 1,000. Volatility is the standard deviation of one round’s total return per 1.00 of total stake. Low under 1.5, Medium 1.5 to under 5, High 5 to under 15, Very high 15 and over. For scale: an even-money roulette bet is 1.00, a straight-up number 5.84.

- RTP: 97% (default), 96% and 98% are built. RTP is set per room, not per player, because everyone in a round sees the same crash point; Topple, Snip, Crash and Updraft share one room. The 10,000x top multiplier can be 1,000x or 5,000x instead; no cap changes the RTP.
