Game Structure and Objectives
The game consists of four rows, each containing three bridges. One bridge in every row hides a hazard. Players select one bridge per active row. The goal is to survive up to four rows to maximize returns. Row four settles automatically. Choosing a hazard ends the round with zero return for that row. The layout is simple and focuses on probability rather than complex features.
Stakes, Payouts, and Settlement
Available stakes are 10, 25, 50, and 100, with 25 as the default. Gross returns for surviving 1 to 4 rows are 1.44x, 2.16x, 3.24x, and 4.86x respectively. These returns include the original stake. The stake is deducted once at the start and persists before animations. Payouts are calculated in hundredths. Fractional carry is kept separately, while whole coins are credited. Surviving all rows yields the highest return.
Wallet Behavior and Controls
The initial balance is 1000 virtual coins. A manual refill is available only when the balance drops below 10 coins. This sets the balance to 1000 rather than adding to it. The refill button is disabled while a round is active. Reloading the page discards any unfinished round without refund or resumption. Controls for stake and mode are disabled during active play. Fractional hundredths are stored locally to ensure precise arithmetic.
Frequently asked questions
Does the demo save unfinished rounds?
No. Reloading the page discards any unfinished round. There is no refund or resumption mechanism for interrupted games.
What is the expected return rate?
The expected return is 96%. Simulated data shows results between 95.79% and 96.07%, confirming the mathematical expectation.
