Game Mechanics and Payouts

Before starting, select one of four exit locks (1 to 4). Each lock has specific survival chances at successive stages: 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 zero return. You cannot manually exit during a round. The default stake is 25, with options for 10, 50, or 100. The expected return to player (RTP) is 96% across all modes, as verified by simulation evidence.

Wallet and Settlement Rules

Your stake is deducted once at the start of the round. Gross returns include the original stake. Payouts are calculated in hundredths; any fractional carry is persisted separately, while only whole coins are credited. Automatic settlement occurs at the chosen exit or end of reveal. A manual refill is available only when the balance is below 10 and sets the balance to 1000. Reloading the page discards any unfinished round without refund or resume.
