Probability and Gross Returns
The game features four rows of three bridges, with one hidden hazard per row. Choosing one bridge per row yields gross returns of 1.44x, 2.16x, 3.24x, and 4.86x for one to four safe rows. The probability of surviving k rows is calculated as (2/3)^k. The expected return function is 0.96 * (3/2)^k, confirming a theoretical RTP of 96%. Row four settles automatically, ending the round regardless of choice.
Settlement and Wallet Arithmetic
The full stake is deducted once at the start and persists before any animation. Payouts are computed in hundredths, then whole coins are credited by flooring the value. Any fractional remainder between 0 and 99 is kept separately and added to future credits. If the balance drops below 10, manual refill restores it to 1000. Reload discards unfinished rounds without refund or resume.
Simulation Evidence and Controls
Simulation data over one million rounds shows simulated RTPs ranging from 95.74% to 96.15%, aligning with the 96% expectation. Stakes are available in denominations of 10, 25, 50, and 100, with 25 as the default. Controls disable during active rounds, and the refill button hides until the round ends. Collecting or hitting the hazard ends the round immediately.
