Game Structure and Payouts

The game consists of four rows, each containing three bridges with one hidden hazard per row. You select one bridge in the active row; choosing a safe bridge allows you to continue or collect. Gross returns for completing one to 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. The expected return is 0.96 based on the game's math.

Stakes, Wallet and Settlement

Stakes are 10, 25, 50, or 100 coins, with 25 as the default. The stake is deducted once at the start and persists before animation. Payouts are calculated in hundredths, with whole coins credited and fractional carry retained separately. A manual refill is available only when the balance is below 10 coins during idle time. Reloading the page discards any unfinished round without a refund.

Controls and Technical Details

Controls for stake selection, starting, and mode switching are disabled while a round is active. The refill button is hidden or disabled during active play. Local storage saves the whole virtual wallet, fractional hundredths, and a pending-round flag. Clearing cache or reloading resets controls and discards unfinished rounds. No account is required to play, and virtual coins have no cash value.
