Orbit Sum Demo: Probability and Payout Examples

The official website of 6qq.

The official website of 6qq. Orbit Sum uses two independent pointers drawing 0–6 uniformly, summed modulo 7. This creates a perfectly uniform distribution across seven outcomes, allowing precise calculation of gross returns based on your chosen arc size.

How Outcomes Are Determined

Each round draws two numbers from 0 to 6 with equal probability. These are added together and taken modulo 7, resulting in a uniform distribution across seven possible outcomes. You select an arc starting at zero with a length of 1, 2, or 3 positions. If the final sum falls within your chosen arc, you win; otherwise, the result is zero. This structure ensures each outcome has an exact 1 in 7 chance of occurring.

Payout Multipliers and Gross Returns

The payout depends on your arc length. 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, meaning the actual profit is the multiplier minus one. For example, a 10-coin stake with a 1-position arc returns 67.2 coins gross. Any fractional carry is preserved separately, while whole coins are credited to your balance.

Simulation Evidence and Expected RTP

Mathematical evidence confirms an expected Return to Player of 96% for all arc choices. Simulations of one million rounds show slight variations: 96.03% for the 1-position arc, 95.77% for the 2-position arc, and 96.09% for the 3-position arc. These figures align closely with the theoretical expectation. The demo uses virtual coins with no cash value, and settlements are automatic upon reveal.

Frequently asked questions

What happens if I reload the page during a round?

The unfinished round is discarded without refund or resume. Your stake remains deducted, and the pending result is lost. You must start a new round to continue playing.

How is the fractional carry handled in payouts?

Payouts are calculated in hundredths. The fractional part is persisted separately and added to the next credit. Whole coins are credited to your balance, while the remainder stays in the fractional carry until it accumulates or is reset.
