Game Structure and Stakes
Paper Bridges features four rows of three bridges, with one hidden hazard per row. Players choose a bridge in the active row, then collect or continue. The default stake is 25, with options of 10, 50, and 100. A stake is deducted once at the start and persisted before any animation. Controls are disabled while the round is active, and the minimum stake is 10.
Payouts and Settlement
Gross returns include the stake and are calculated as 1.44x, 2.16x, 3.24x, and 4.86x for one to four safe rows. Payouts are computed in hundredths, with fractional carry saved separately. Credits are given as floor whole coins, keeping the remainder. The fourth row settles automatically, and a hazard results in zero. Reloading discards unfinished rounds without refund.
Wallet and Math Evidence
The initial balance is 1000 coins. Manual refill is available when idle and the balance drops below 10, setting the balance to 1000. Simulated RTP for various choices hovers around 95.9%, matching the expected 96% return. LocalStorage saves the whole wallet, fractional hundredths, and the pending-round flag.
