Survival Odds and Gross Returns

Before starting, you choose an exit lock from one to four. Each lock has independent survival chances of eighty percent, seventy-five percent, two thirds, and fifty percent. Reaching your chosen exit returns gross multipliers of 1.2x, 1.6x, 2.4x, or 4.8x. Failure returns zero, and you cannot exit manually during the round. The stake is deducted once at the start and persists before any animation begins.

Expected Return and Simulation Evidence

The score function multiplies survival rates by gross returns, yielding values of 0.96, 0.6, 0.4, and 0.2. Simulation evidence over one million rounds shows an expected return to player rate of ninety-six percent. Simulated results ranged from 95.66% to 96.02%, confirming the mathematical expectation. Payouts are computed in hundredths, with fractional carry kept separate from credited whole coins.

Wallet Rules and Settlement Details

Stakes are ten, twenty-five, fifty, or one hundred virtual coins, with twenty-five as the default. Settlement is automatic at the chosen exit or end of reveal. A manual refill is only available when idle and the balance falls below ten coins. The refill sets the balance to one thousand rather than adding to it. Reloading the page discards any unfinished round without refund or resumption.
