Survival Probabilities and Gross Returns

You select one of four exit locks before starting. The survival chances for each lock are 80%, 75%, two-thirds, and 50%. Reaching your chosen exit yields gross returns 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 confirms these probabilities by multiplying survival rates against gross multipliers.

Stakes, Settlement, and Wallet Rules

Stakes are 10, 25, 50, or 100 virtual coins, with 25 as the default. Your stake is deducted once at the start and persists before animation. Payouts are computed in hundredths, adding any saved fractional carry, crediting the floor of whole coins, and keeping the remainder. Automatic settlement occurs at the exit or end of reveal. Reload discards unfinished rounds without refund.

Wallet Management and Data Storage

Your initial balance is 1,000 virtual coins. Manual refill is available only when idle and balance is below 10, setting the balance to 1,000. Whole coins are stored in localStorage, along with fractional hundredths and a pending-round flag. Controls are disabled while active. This demo uses virtual coins with no cash value and no cashier.
