Game Mechanics and Payouts

Each round features four independent tiles showing one of three shapes. You count matching adjacent pairs across three seams. Each match returns 0.96x gross, totaling 0x, 0.96x, 1.92x, or 2.88x. The expected return is 0.96x per seam. Stakes are 10, 25, 50, or 100, with 25 as the default. Controls disable during active rounds, and refill hides until idle.

Settlement and Wallet Logic

Stake deducts once at start and persists before animation. Payouts compute in hundredths, adding saved fractional carry while crediting floor whole coins. The remainder stays as fractional carry. Settlement happens automatically at exit or reveal end. Reload discards unfinished rounds without refund or resume. The wallet saves whole coins and fractional hundredths in localStorage.

Controls and Restoration Rules

Manual idle refill restores balance to 1000 only when below 10. Exit or arc choice resets balance to 1 on reload. No manual stop or autoplay exists. The demo requires no account, using virtual coins with no cash value. Separate external buttons do not establish affiliation. Privacy notes include localStorage usage and third-party analytics like Statinside.

Frequently asked questions

How is the stake handled during a round?

The stake deducts once at the start and persists before animation. If you reload, the unfinished round discards without refund, and the stake remains deducted.

What happens when the balance is low?

Manual refill is available only when idle and balance drops below 10. It sets the balance to 1000 rather than adding to it, preserving the fractional carry separately.
