Survival Probabilities and Gross Returns
Players select one of four exit locks before starting. The survival chances at successive locks are 80%, 75%, two-thirds, and 50%. Reaching your chosen exit yields a gross return of 1.2×, 1.6×, 2.4×, or 4.8× your stake. Failure results in a zero return. The score function multiplies survival rates by gross returns, yielding 0.96, 0.6, 0.4, and 0.2 respectively. This indicates the expected return relative to the initial stake.
Stakes, Settlement, and Wallet Mechanics
Available stakes are 10, 25, 50, and 100 virtual coins, with 25 as the default. The stake is deducted once at the start and persists before any animation. Payouts are computed in hundredths. A fractional carry between 0 and 99 is saved separately. The system credits floor whole coins and keeps the remainder. Settlement is automatic at the exit or end of reveal. There is no manual stop or autoplay. Reloading the page discards any unfinished round without refund or resume.
Wallet Restoration and Storage Details
The initial balance is 1000 virtual coins. Manual restoration is available only when the balance drops below 10 and sets the balance to 1000. The whole coin wallet and fractional hundredths are stored in localStorage. Controls reset on reload. The minimum stake is 10. During an active round, stake, start, and mode controls are disabled. Refill is hidden or disabled while active. The demo uses virtual coins with no cash value, deposit, or withdrawal.
