Game Mechanics and Payout Structure
Paper Bridges features four rows with three bridges each, hiding one hazard per row. You select one bridge per row to survive. Surviving four rows yields a gross return of 4.86 times your stake. The game settles automatically after the fourth row if you do not collect earlier. Stakes available are 10, 25, 50, or 100 coins, with 25 as the default. The stake is deducted once at the start and persists before any animation plays.
Wallet Rules and Settlement Details
Gross returns include your original stake. Payouts are computed in hundredths, then whole coins are credited by flooring the value. Any fractional carry between 0 and 99 is saved separately and added to future credits. If your balance drops below 10 while idle, you can manually refill to restore 1000 coins. Reloading the page discards any unfinished round without a refund or resumed settlement.
Probabilities and Simulation Evidence
The expected return is 96 percent, calculated as (2/3)^k multiplied by the gross multiplier. Simulation data over one million rounds confirms this, with observed returns ranging from 95.88 to 96.31 percent depending on the choice mode. These figures represent long-term expectations, not short-term guarantees. The demo uses virtual coins with no cash value, and no external cashier is involved.
Frequently asked questions
What happens if I reload the page during a round?
The unfinished round is discarded immediately. Your stake remains deducted, and you receive no refund or resume option for that specific round.
How are fractional payouts handled in this demo?
Payouts are calculated in hundredths. Whole coins are credited by flooring the result, while the remaining fractional value is saved as carry-over to be added to future credits.
