Arc Selection and Gross Returns

The game sums two independent pointers, each drawing 0–6 uniformly. The result is taken modulo 7, creating a uniform distribution across 0–6. You choose an arc of 1, 2, or 3 positions starting at zero. A result in your arc returns gross multipliers of 6.72x, 3.36x, or 2.24x respectively. Other results return zero. The stake is deducted once at the start and persists before animation begins.

Settlement and Fractional Carry

Gross returns include your stake. Payouts are computed in hundredths, with any fractional carry added to the credit. The system credits floor whole coins and keeps the remainder between 0 and 99 as a separate fractional carry. This ensures precise tracking of virtual coin values without rounding errors during settlement. Automatic settlement occurs at the chosen exit or end of reveal, with no manual stop option.

Reload Rules and Wallet Mechanics

Reloading the page discards any unfinished round without refund or resumed settlement. The wallet starts with an initial balance of 1000 virtual coins. You can manually refill to 1000 only when idle and the balance falls below 10. Controls for stake, start, and mode are disabled while active. The demo uses virtual coins with no cash value, deposit, or withdrawal features.
