Survival Odds and Gross Returns
In Ferry Locks, you choose an exit lock between 1 and 4 before starting. The chances of survival at successive locks are 80%, 75%, two-thirds, and 50%. Reaching your chosen exit returns a gross multiplier of 1.2×, 1.6×, 2.4×, or 4.8×. Failure results in zero return, and you cannot exit manually during the round. The score function multiplies survival rates by gross returns to yield 0.96, 0.48, 0.32, and 0.16 respectively.
Settlement and Wallet Mechanics
The stake is deducted once at the start and persists before any animation. Payouts are computed in hundredths, with fractional carry added to credit floor whole coins. The remainder stays between 0 and 99. Automatic settlement occurs at the chosen exit or end of reveal. Reload discards unfinished rounds without refund. A manual idle refill sets the balance to 1000 only when below 10.
