Orbit Sum: Probability and Payout Guide

The official website of gb999.

The official website of gb999. Orbit Sum uses two independent pointers to generate a sum modulo 7. Your gross return depends on selecting an arc of 1, 2, or 3 positions, offering multipliers of 6.72x, 3.36x, or 2.24x respectively.

Arc Selection and Gross Returns

The game calculates results by adding two uniform draws from 0 to 6, then taking the sum modulo 7. If the result falls within your chosen arc starting at zero, you receive a gross return. Choosing one position yields 6.72 times your stake, two positions yield 3.36 times, and three positions yield 2.24 times. These returns include your original stake, meaning the net profit is the multiplier minus one. Results outside your selected arc return zero.

Settlement and Fractional Carry

Settlement is automatic upon the end of the reveal. The system computes payouts in hundredths of a coin. Any fractional carry is persisted separately and added to the credited whole coins. The floor of the total is credited to your balance, while the remainder between zero and ninety-nine is kept. This ensures precise tracking of virtual coin values without rounding errors affecting your total balance immediately.

Expected Return and Simulation

The score function ensures that the product of the probability k over 7 and the multiplier 6.72 over k equals 0.96. Simulation data confirms this with an expected RTP of 96 percent. One million rounds for each choice mode showed simulated RTPs ranging from 95.89 to 95.97 percent. This evidence supports the mathematical consistency of the demo's payout structure.

Frequently asked questions

Does reloading the page refund my stake?

No. Reloading discards any unfinished round without a refund or resumption of the settlement. The stake remains deducted from your balance.

How is the balance restored when it is low?

You can manually restore your balance to 1000 coins when idle and the balance falls below ten. This sets the balance to that specific amount rather than adding to it.
