Orbit Sum: Probability and Payout Analysis

The official website of 77ww.

Orbit Sum uses two independent pointers to generate a sum modulo 7, determining your payout based on a selected arc. This guide details the exact probabilities, gross returns, and wallet behavior for this specific demo environment.

Game Mechanics and Probability

Two independent pointers each draw a value from 0 to 6 uniformly. These values are added together and reduced modulo 7, resulting in a sum that is uniformly distributed from 0 to 6. Players select an arc of 1, 2, or 3 positions starting at zero. If the final sum falls within the chosen arc, the bet is successful. The probability of winning is exactly k divided by 7, where k is the number of positions in the selected arc.

Gross Payouts and Returns

Successful outcomes yield gross returns of 6.72x, 3.36x, or 2.24x for arc lengths of 1, 2, or 3 respectively. These gross amounts include the original stake. The expected return to player is 96 percent across all modes. Simulation data confirms this expectation, showing simulated RTPs of 96.09 percent, 96.12 percent, and 95.91 percent for the three modes over one million rounds.

Wallet Rules and Settlement

The stake is deducted once at the start of the round and persists before any animation. Payouts are calculated in hundredths. Any fractional carry is kept separately, while whole coins are credited to your balance. If you reload the page, any unfinished round is discarded without a refund or resume option. You can manually restore your balance to 1000 coins only when idle and below 10 coins.

Frequently asked questions

How is the final score determined?

Two pointers draw values from 0 to 6 uniformly. The sum of these values is calculated modulo 7 to produce a result between 0 and 6.

What happens to my stake if I reload the page?

The stake remains deducted. The unfinished round is discarded entirely, and there is no refund or automatic resume of the previous state.
