Orbit Sum: Probability and Payout Examples

Game Mechanics and Arc Selection

Two pointers independently select a number from 0 to 6. These values are added and reduced modulo 7, creating a uniform distribution across results 0–6. Players select an arc length of 1, 2, or 3 positions starting at zero. If the result falls within the chosen arc, the bet is paid at the corresponding gross multiplier. Results outside the arc return zero. The default stake is 25 coins, with options for 10, 50, or 100 coins. Controls disable during active rounds, and reloading discards any unfinished round without refund.

Expected Return and Simulation Data

The game maintains a consistent expected return to player (RTP) of 96 percent across all arc choices. Simulation data confirms this stability with measured RTPs of 96.245856 for arc 1, 96.032496 for arc 2, and 95.935168 for arc 3 over one million rounds each. Gross returns include the original stake. Payouts are computed in hundredths, with fractional carry persisted separately and credited whole coins added to the balance. The remainder remains in the fractional carry until it accumulates to a whole coin.

Wallet Rules and Settlement

Stakes are deducted once at round start and persisted before animation begins. Automatic settlement occurs at the end of the reveal with no manual stop or autoplay. Refilling coins is manual and only available when the balance falls below 10 coins, setting the balance to 1000 coins rather than adding to it. The wallet stores whole coins and fractional hundredths in local storage. Reloading the page resets controls and discards pending rounds without resuming settlement.
