Game Mechanics and Gross Returns
Paper Bridges features four rows of three bridges with one hidden hazard per row. You select a bridge in the active row, and safe progression yields gross returns of 1.44x, 2.16x, 3.24x, and 4.86x for one to four safe rows. The stake is deducted once at the start and persists before any animation. Row four settles automatically, and you can manually collect after any safe row. A hazard ends the round with zero return. The score function reflects an expected return of 0.96, aligning with the 96% RTP observed in simulation data.
Wallet Rules and Fractional Carry
The demo uses a virtual wallet with an initial balance of 1000 coins. Stakes are set at 10, 25, 50, or 100, with 25 as the default. Payouts are computed in hundredths, and any fractional carry is kept separate from credited whole coins. When you refill manually, the balance is set to a specified amount only if it falls below 10, rather than adding to it. Whole coins are stored in local storage, and the fractional remainder is preserved even during refills. An unfinished round does not save; reloading discards it without refund.
Settlement, Controls, and Access
You can choose to collect after any safe row or wait for automatic settlement after the fourth row. Choosing to exit or arc resets the game to one on reload, discarding any unfinished progress. Controls for stake, start, and mode are disabled while active, and manual refill is hidden during gameplay. The demo requires no account, using local storage for state. External login or play buttons link to unverified services. The intended audience is 18+, though no strict age gate is enforced.

Frequently asked questions
How are fractional coins handled in payouts?
Payouts are calculated in hundredths. The system credits the floor of whole coins to your balance and keeps the remainder as a fractional carry. This fraction persists separately and is added back when you refill or continue, ensuring no value is lost during whole-coin transfers.
What happens if I reload the page mid-round?
Reloading discards any unfinished round without refund or resumed settlement. The initial stake remains deducted from your balance, and the game resets to the first row. You must start a new round to play again, as no progress is saved across page refreshes.
