Game Mechanics and Payouts

The game features four independent tiles, each displaying one of three equally likely shapes. Players count matching adjacent pairs across the three seams. Each match returns 0.96 times the gross stake. The total payout is 0x, 0.96x, 1.92x, or 2.88x based on the number of matches. The expected return is 0.96, meaning the game retains 4% of wagers over time.

Stakes and Settlement

Available stakes are 10, 25, 50, and 100 coins, with 25 as the default. The stake is deducted once at the start and persists before any animation. Settlement is automatic upon exit or reveal completion. There is no manual stop or autoplay. Reloading the page discards any unfinished round without refund or resumption.

Wallet and Controls

The demo starts with 1000 virtual coins. Manual refill is only available when the balance drops below 10 coins while idle, setting the balance to 1000. Fractional carry is stored separately in hundredths, while whole coins are credited. Controls disable during active rounds. Data is saved in localStorage, and no external payment or withdrawal exists.
