Row Probabilities and Gross Returns

Each row has three bridges with one hazard, giving a two-thirds chance of survival per row. Choosing one bridge in each active row allows you to collect or continue. Gross returns after one, two, three, or four safe rows are 1.44x, 2.16x, 3.24x, and 4.86x respectively. The fourth row settles automatically if you do not collect earlier.

Stakes and Settlement Rules

Stakes are 10, 25, 50, or 100 virtual coins, with 25 as the default. The stake is deducted once at the start and persists before any animation. Payouts are computed in hundredths, with fractional carry kept separately. Whole coins are credited, and the remainder stays as carry. Reloading discards unfinished rounds without refund or resumed settlement.

Simulated Evidence and Wallet Behavior

Simulation evidence shows expected RTP of 96% with simulated results around 96.09% to 96.31%. The wallet starts with 1000 coins and can be manually refilled when idle and below 10 coins. Controls are disabled while active, and minimum stake is 10. Local storage saves the wallet, fractional hundredths, and pending-round flag.
