Game Mechanics and Payouts

Two pointers each draw a number from zero to six with equal probability. These values are added and taken modulo seven to produce a result between zero and six. You must select an arc of one, two, or three positions starting from zero. If the result falls within your chosen arc, you receive a gross return of 6.72x, 3.36x, or 2.24x respectively. Any result outside your arc returns zero. The game has a theoretical return to player of ninety-six percent.

Wallet and Settlement

Stakes of ten, twenty-five, fifty, or one hundred coins are available, with twenty-five as the default. The stake is deducted immediately when the round begins. Gross returns include the original stake. Payouts are calculated in hundredths, with whole coins credited and the fractional remainder kept as a carry. Settlement occurs automatically at the end of the reveal. Reloading the page discards any unfinished round without a refund.

Controls and Limits

You can preselect the arc length from one to three positions, all starting at zero. Controls for stake and mode are disabled while the round is active. Manual coin restoration is available only when the balance falls below ten coins and sets the balance to one thousand. There is no manual stop or autoplay feature. The demo uses virtual coins with no cash value and requires no account.
