Game Structure and Payouts
Paper Bridges features four rows with three bridges each. One hazard hides per row, giving a two-thirds chance of safety per row. Gross returns scale with each safe row: 1.44x after row one, 2.16x after row two, 3.24x after row three, and 4.86x after row four. The game settles automatically after the fourth row. Stakes include 10, 25, 50, and 100 coins, with 25 as the default. A stake is deducted once at the start and persists through the round.
Mathematical Expectation and Simulation
The expected return is 0.96, or 96 percent. Simulations of one million rounds confirm this, showing results between 95.94 and 96.13 across different modes. The score function follows the pattern of two-thirds to the power of k, multiplied by 0.96, times three-halves to the power of k. This confirms the mathematical expectation aligns with the observed simulation data. The game does not guarantee wins or define session targets.
Wallet Rules and Settlement
Payouts are computed in hundredths. Any fractional carry is saved separately from credited whole coins. The system credits the floor of whole coins and keeps the remainder. If the balance drops below ten coins, you can manually refill to restore one thousand coins. Reloading the page discards unfinished rounds without refund. Controls disable during active play to prevent stake changes.
