How Probability and Payouts Work

Each row has three bridges with one hidden hazard, giving a two-thirds chance of safety per row. Gross returns for completing one to four rows are 1.44x, 2.16x, 3.24x, and 4.86x respectively. These returns include your original stake and are calculated before any fractional carry is added to your balance. The expected return rate is ninety-six percent, meaning the game retains four percent of all wagers over time.

Settlement and Wallet Rules

Stakes of ten, twenty-five, fifty, or one hundred are deducted once at the start of a round. If you survive four rows, the game settles automatically; otherwise, you may collect after any safe row. Fractional hundredths are persisted separately, while whole coins are credited to your wallet. Reloading the page discards any unfinished round without a refund or resume option.

Simulation Evidence and Controls

One million simulated rounds show a simulated RTP between ninety-five point seven and ninety-six point two percent, aligning with the expected ninety-six percent. You can choose stakes from ten to one hundred, with twenty-five as the default. Manual balance restoration is available only when idle and the balance falls below ten, setting the balance to one thousand. Controls disable during active rounds to prevent invalid actions.

Frequently asked questions

What happens to my stake if I reload the page?
