Game Mechanics

Two pointers each draw a number from 0 to 6 with equal probability. The results are added together and taken modulo 7, producing a uniform sum from 0 to 6. You select an arc of 1, 2, or 3 positions starting at zero. If the result falls within your chosen arc, you receive a gross payout of 6.72x, 3.36x, or 2.24x respectively. Any result outside your arc returns zero.

Stakes and Settlement

Available stakes are 10, 25, 50, and 100 coins, with 25 as the default. The stake is deducted once at the start and persisted before animation. Payouts are computed in hundredths, with fractional carry added to credit floor whole coins. Settlement is automatic at the end of the reveal, with no manual stop or autoplay available. Reloading discards the unfinished round without refund.

Wallet and Controls

The initial balance is 1000 coins. Manual refill is available only when idle and balance drops below 10, setting the balance to 1000. Controls disable during active rounds. Wallet data is stored in localStorage, including whole coins and fractional hundredths. No account is required for this demo.
