Orbit Sum: Probability and Payout Examples

Orbit Sum uses two independent pointers that draw numbers from 0 to 6 uniformly. The results are added and taken modulo 7, creating a uniform distribution of outcomes from 0 to 6.

How the Game Works and Stakes

Two pointers select values between 0 and 6. These values are summed and reduced modulo 7, ensuring each result from 0 to 6 has an equal probability of 1/7. You choose an arc length of 1, 2, or 3 positions starting at zero. Available stakes are 10, 25, 50, or 100 virtual coins, with 25 as the default. The stake is deducted immediately when the round starts and remains deducted until settlement.

Payout Multipliers and Settlement

If the final modulo 7 result falls within your selected arc, you win. A 1-position arc pays 6.72x gross, a 2-position arc pays 3.36x, and a 3-position arc pays 2.24x. Gross returns include your original stake. Settlement is automatic upon the end of the reveal. If the result is outside your arc, you receive zero. The game does not allow manual stopping or autoplay.

Wallet Mechanics and Reload Rules

Your balance is stored in whole coins and a separate fractional carry of hundredths. When you refill manually while idle, the balance is set to 1000 coins if below 10. Fractional carry is preserved separately. Reloading the page discards any unfinished round without refund or resumption. The stake remains deducted during the reload process.

Frequently asked questions

What is the expected return for Orbit Sum?

The expected return to player is 96%. Simulation data confirms this with results around 96.00% across different arc choices.

Does reloading the page refund my stake?

No. Reloading discards the unfinished round without refund. The stake remains deducted, and you must start a new round.
