Game Mechanics and Payout Structure

The Paper Bridges demo features four rows of three bridges, with one uniformly hidden hazard per row. You choose one bridge in the active row to either collect or continue. Gross returns for completing one to four safe rows are 1.44x, 2.16x, 3.24x, and 4.86x respectively. The stake is deducted once at the start, and the fourth row settles automatically. Available stakes are 10, 25, 50, and 100, with 25 as the default. Any fractional carry is kept separately, and whole coins are credited based on the floor value.

Probability and Expected Returns

The expected return is calculated using the formula (2/3)^k * 0.96 * (3/2)^k, resulting in a score of 0.96. Simulation data for one million rounds shows simulated returns ranging from 95.94% to 96.09%, closely aligning with the expected 96% RTP. These figures represent long-term statistical expectations rather than guaranteed session outcomes. The hazard distribution ensures a uniform probability per row, influencing the gross payout multipliers.

Wallet Rules and Settlement

The demo uses virtual coins with no cash value. The initial balance is 1000 coins, and manual restoration is available only when the balance drops below 10, setting the balance to 1000 rather than adding to it. Reloading the page discards any unfinished round without refund or resume. Controls for stake and mode are disabled while active. The game requires no account, and external login buttons do not establish affiliation with the demo.

Frequently asked questions

How are fractional amounts handled in the demo?

Payouts are computed in hundredths. The system adds the saved fractional carry and credits the floor of the whole coins, keeping the remainder between zero and ninety-nine.

What happens if I reload the page during a round?

Any unfinished round is discarded without a refund or resumed settlement. The stake remains deducted, and controls reset upon reload.
