Arc Selection and Gross Payouts

The game uses two independent pointers that draw values from 0 to 6. These values are summed and taken modulo 7 to produce a result between 0 and 6. Players select an arc of 1, 2, or 3 positions starting from zero. If the result falls within the chosen arc, the player receives a gross return of 6.72x, 3.36x, or 2.24x respectively. Any other result yields zero. The gross return includes the original stake.

Probability and Expected Return

The score function ensures that the sum modulo 7 is uniformly distributed across all seven possible outcomes. The expected return for any chosen arc is exactly 96%. Simulation data confirms this with simulated RTPs of approximately 96.05%, 95.92%, and 96.14% across one million rounds for different choices. This confirms the theoretical probability holds in practice.

Wallet Rules and Settlement

The stake is deducted once at the start and persisted before animation. Payouts are calculated in hundredths, with fractional carry added to credit whole coins. The remainder is kept separately. A manual refill is available only when the balance drops below 10 coins. Reloading the page discards unfinished rounds without refund. Controls are disabled while the round is active.
