Game Mechanics and Structure
The Paper Bridges demo features four rows of three bridges, with one uniformly hidden hazard per row. Players choose one bridge in the active row to proceed. After surviving one to four safe rows, gross returns are 1.44x, 2.16x, 3.24x, and 4.86x respectively. The game settles automatically after the fourth row. Stakes can be set to 10, 25, 50, or 100, with 25 as the default. Exiting or reloading the page resets the game state.
Probability and Return to Player
The expected return to player is 96%, calculated as (2/3)^k * 0.96 * (3/2)^k. Simulation evidence supports this, showing simulated RTPs of 96.05%, 96.06%, 95.96%, and 96.29% across different choice modes over one million rounds. These figures confirm the mathematical expectation without guaranteeing session results. The game distinguishes between exact mathematical expectations and measured simulation estimates.
Wallet, Settlement and Controls
A captured whole stake is deducted once at the start and persisted before any animation. Gross returns include the stake, differing from net profit. Fractional carry is stored separately in hundredths, while whole coins are credited and stored in localStorage. Manual restoration is available only when idle and the balance falls below 10, setting the balance to 1000 rather than adding to it. Reloading discards unfinished rounds without refund or resumed settlement.
