Paper Bridges: Worked Probability and Payout Examples

Probability and Gross Payouts

Paper Bridges features four rows with three bridges each, where one hazard is hidden per row. Choosing a safe bridge increases your multiplier: 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. Each safe step multiplies your initial stake by the specific row factor, with the gross return including your original stake. If you hit a hazard, you receive zero for that row and the round ends immediately.

Wallet Behavior and Settlement Rules

Stakes of 10, 25, 50 or 100 coins are deducted once at the start and persist before any animation. The payout is calculated in hundredths, adding any saved fractional carry before crediting whole coins to your balance. Manual refill is only available when idle and your balance drops below 10 coins, setting the balance to 1000 rather than adding to it. Reloading the page discards unfinished rounds without refund or resumption, and controls remain disabled while the game is active.

Simulated Performance and Evidence

Simulation data from one million rounds confirms an expected return to player (RTP) of 96%. Measured simulated RTPs across different modes range from 95.74% to 95.92%, closely aligning with the theoretical 0.96 multiplier factor. These figures represent long-term statistical expectations rather than guarantees for individual sessions. The demo uses virtual coins with no cash value, and no external cashier or withdrawal mechanism exists within this local interface.
