Ferry Locks: Probability and Payout Guide

Survival Probabilities and Gross Returns

In Ferry Locks, you choose an exit lock from one to four before starting. Each lock has a specific survival chance: lock one is eighty percent, lock two is seventy-five percent, lock three is two-thirds, and lock four is fifty percent. Reaching your chosen exit pays a gross multiplier of 1.2x, 1.6x, 2.4x, or 4.8x respectively. Failure returns zero, and you cannot exit manually during the round. The score function multiplies survival rates by gross returns, showing expected values of 0.96, 0.6, 0.4, and 0.2 for exits one through four.

Stakes, Settlement and Wallet Rules

Stakes are set to ten, twenty-five, fifty, or one hundred virtual coins, with twenty-five as the default. Your stake is deducted once at the start and persists before any animation begins. Payouts are computed in hundredths, adding any saved fractional carry before crediting whole coins. The remainder between zero and ninety-nine is kept separately. Automatic settlement occurs at your chosen exit or the end of the reveal. There is no manual stop or autoplay. Reloading discards any unfinished round without refund or resumed settlement.

Mathematical Evidence and Controls

Simulation data over one million rounds shows expected returns near ninety-six percent, with simulated results ranging from ninety-five point seven to ninety-six point zero one. Controls include stake selection, start round, and preselecting exit one through four. The refill feature is manual and only active when the balance drops below ten coins. During active play, stake, start, and mode controls are disabled. The demo uses local storage for whole virtual wallets and fractional hundredths, resetting controls on reload.
