Ferry Locks

Virtual coins only. No account, no payment, no prizes.

Game Mechanics and Payouts

Before starting, you must choose one of four exit locks. Each lock has distinct survival probabilities for successive stages: 80%, 75%, two-thirds, and 50%. If you reach your chosen exit, you receive a gross payout multiplier of 1.2x, 1.6x, 2.4x, or 4.8x. Failure at any stage returns zero. You cannot manually exit during the round; settlement is automatic upon reaching the exit or failing.

Wallet, Stakes, and Settlement

The game uses virtual coins with no cash value. You can select stakes of 10, 25, 50, or 100, with 25 as the default. The entire stake is deducted immediately upon starting, even before animations begin. Payouts are calculated in hundredths, with fractional carry preserved separately. A manual refill is only available when idle and the balance falls below 10, setting the balance to 1000 rather than adding to it.

Data Storage and Reload Behavior

Your wallet state, including whole coins and fractional hundredths, is saved in localStorage. If you reload the page, any unfinished round is discarded without refund or resumption, and the stake remains deducted. Controls are disabled while the round is active. The game is intended for an 18+ audience but has no enforced age gate. External login buttons link to unverified services.

Frequently asked questions

What happens if I reload the page during a round?

The round is discarded without a refund. Your initial stake remains deducted, and you do not resume from where you left off.

How is the fractional carry handled in payouts?

Payouts are calculated in hundredths. The fractional remainder is persisted separately and added back when whole coins are credited to your balance.
