Survival Probabilities and Gross Returns

You select an exit lock between one and four before the round begins. The survival chances at successive locks are eighty percent, seventy-five percent, two-thirds, and fifty percent. Reaching your chosen exit yields a gross return 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 multiplies these survival rates by the gross multipliers, resulting in values of 0.96, 0.6, 0.4, and 0.2 respectively.

Stake Deduction and Settlement Rules

Your stake is deducted once at the start and persists before any animation begins. Payouts are computed in hundredths, with a fractional carry saved separately. The system credits floor whole coins and retains the remainder between zero and ninety-nine. Automatic settlement occurs at your chosen exit or the end of the reveal. There is no manual stop or autoplay, and reloading discards any unfinished round without refund.

Wallet Mechanics and Balance Restoration

The demo uses virtual coins with no cash value. A captured whole stake is deducted once at the start. Gross return includes the stake and differs from net profit. Manual restoration is available only when the balance is below ten coins while idle, setting the balance to one thousand. A saved wallet does not save an unfinished round; use the no-refund reload rule. Controls for stake and start are disabled while the round is active.

Frequently asked questions

How is the gross return calculated?

Gross return is calculated by multiplying the survival probability of your chosen exit lock by the specific payout multiplier for that lock. This value includes your original stake.

What happens if I reload the page?

Reloading discards any unfinished round without refund or resumed settlement. The stake remains deducted, and you must start a new round.
