Game Mechanics and Payouts

Before starting, select one of four exit locks. Each lock has independent survival chances: 80%, 75%, two-thirds, and 50%. Reaching your chosen exit returns a gross multiplier of 1.2x, 1.6x, 2.4x, or 4.8x. Failure results in zero return, and you cannot exit manually during the round. The score function calculates survival at exits as 0.8, 0.6, 0.4, and 0.2, multiplied by the gross multipliers to yield 0.96.

Wallet and Settlement

Stakes are 10, 25, 50, or 100 coins, with 25 as the default. The stake is deducted once at the start and persists before animation. Payouts are computed in hundredths, with fractional carry saved separately. Whole coins are credited, and the remainder is kept. Automatic settlement occurs at the exit or end of reveal. Reload discards unfinished rounds without refund.

Controls and Access

Controls for stake, start, and mode are disabled while active. Manual idle refill is only available when the balance drops below 10 coins, setting the balance to 1000. The demo requires no account, but external buttons may navigate to unverified services. Local storage saves the wallet and pending round flags.
