Survival Probabilities and Gross Returns
Players select an exit lock between one and four before the round begins. The survival chances at successive locks are 80%, 75%, two-thirds, and 50%. Reaching the chosen exit yields a gross return of 1.2x, 1.6x, 2.4x, or 4.8x. Failure results in zero return, with no manual exit allowed during the round. The score function multiplies survival rates by gross returns to determine expected value.
Stakes, Settlement and Wallet Rules
Available stakes are 10, 25, 50, or 100 virtual coins, with 25 as the default. The stake is deducted once at the start and persists before any animation. Payouts are computed in hundredths, with fractional carry saved separately and whole coins credited. Automatic settlement occurs at the exit or end of the reveal, with no manual stop or autoplay. Reloading discards unfinished rounds without refund or resume.
Mathematical Evidence and Simulation Data
Simulation data from one million rounds confirms expected returns near 96%. Simulated RTP values range from 95.90% to 96.16% across different choices. The initial balance is 1000 coins, with manual refill available only when idle and below 10 coins. Controls disable during active rounds, and the fractional hundredths are persisted in local storage.
Frequently asked questions
How is the gross return calculated in Ferry Locks?
The gross return includes the original stake and is determined by the survival probability at the chosen exit. Values range from 1.2x to 4.8x based on the difficulty of the selected lock.
What happens to my balance if I reload the page?
Reloading discards any unfinished round without refund or resuming settlement. The stake remains deducted, and the saved wallet restores only to the initial balance if the manual refill condition is met.
