Orbit Sum Demo: Probability and Payout Guide

Orbit Sum uses two independent pointers that draw 0–6 uniformly and add them modulo 7. Your payout depends on choosing an arc of 1, 2, or 3 positions starting at zero, with gross returns of 6.72x, 3.36x, or 2.24x if the sum lands in your selected arc.

How Stakes and Arcs Work

You can select stakes of 10, 25, 50, or 100 coins, with 25 as the default. Before the round starts, the stake is deducted once and persists through the animation. You must preselect an arc length of 1, 2, or 3 positions, all starting at zero. If the calculated sum lands within your chosen arc, you win the corresponding gross multiplier; otherwise, you receive zero.

Settlement and Fractional Carry

The payout is calculated in hundredths of a coin. Any fractional carry is persisted separately and added to your balance later. The system credits the floor of the whole coins while keeping the remainder (0–99) for future accumulation. Settlement is automatic upon the end of the reveal, and there is no manual stop or autoplay option. Reloading the page discards any unfinished round without a refund.

Simulation Evidence and Limits

Simulations with one million rounds show an expected RTP of 96%. The observed simulated RTPs are 95.69% for 1x arcs, 95.89% for 2x arcs, and 96.04% for 3x arcs. These figures represent statistical expectations and do not guarantee session outcomes. The demo uses virtual coins with no cash value, and no cashier or external payments are involved.

Frequently asked questions

What happens if I reload the page during a round?

The stake remains deducted from your balance, and the unfinished round is discarded without a refund or resume option.

How is the fractional part of a payout handled?

The fractional hundredths are persisted separately and added to your balance later, while only the floor of the whole coins is credited immediately.
