Survival Probabilities and Gross Returns

Before starting, you select an exit lock from one to four. Each lock has a specific independent survival chance. Lock 1 has an 80 percent survival rate and pays 1.2 times your stake. Lock 2 has a 75 percent survival rate and pays 1.6 times your stake. Lock 3 has a two-thirds survival rate and pays 2.4 times your stake. Lock 4 has a 50 percent survival rate and pays 4.8 times your stake. Failure at any lock returns zero. You cannot exit manually during the round.

Payout Calculation and Settlement

The gross return includes your original stake. The stake is deducted once at the start and persists before any animation. Payouts are computed in hundredths. A fractional carry is kept separately, while only whole coins are credited to your balance. Automatic settlement occurs at your chosen exit or the end of the reveal. There is no manual stop or autoplay option. Reload discards any unfinished round without refund.

Wallet Rules and Refills

The demo uses virtual coins with no cash value. Your initial balance is one thousand coins. You can choose stakes of ten, twenty-five, fifty, or one hundred, with twenty-five as the default. A manual refill is available only when your balance drops below ten coins while idle. This sets your balance to one thousand coins rather than adding to it. Controls are disabled while a round is active.

Frequently asked questions

Does reloading the page refund an unfinished round?

No. Reloading discards any unfinished round without refund or resumed settlement. The stake remains deducted from your balance.

How is the fractional carry handled in payouts?

The fractional carry is stored as integer hundredths separately from the main balance. Whole coins are credited, and the remainder is retained until it reaches a full coin or the round ends.
