Game Mechanics and Payout Structure

Mosaic Seams uses four independent tiles, each displaying one of three equally likely shapes. Players count matching adjacent pairs across three seams. Each match returns a gross payout of 0.96 times the stake. The total payout scales with matches: zero matches yield zero, one match yields 0.96 times, two matches yield 1.92 times, and three matches yield 2.88 times. The game supports stakes of 10, 25, 50, or 100 virtual coins, with 25 as the default. The stake is deducted once at the start and persists before animation begins.

Probability and Expected Return

Each of the three equal adjacent pair indicators has a probability of one-third. The linear expectation calculates to three times one-third times 0.96, resulting in an expected return of 0.96. Simulation data from one million rounds confirms a simulated RTP of 95.92848, closely aligning with the theoretical 96 percent. Payouts are computed in hundredths, with fractional carry persisted separately. The system credits floor whole coins and retains the remainder between zero and ninety-nine.

Wallet Rules and Settlement

The demo uses a virtual wallet where the initial balance is one thousand coins. Settlement is automatic at the exit or end of reveal, with no manual stop or autoplay available. Reloading the page discards any unfinished round without refund or resumption. The stake remains deducted even if the round is not completed. When the balance falls below ten coins while idle, a manual refill restores the balance to one thousand. Controls disable during active rounds, and the refill button hides until the round ends.

Frequently asked questions

Does reloading the page refund an unfinished round?

No. Reloading discards the unfinished round without refund. The stake remains deducted from the wallet, and the round does not resume upon return.

How are fractional payouts handled in the wallet?

Payouts are calculated in hundredths. The system credits floor whole coins to the wallet and persists the fractional remainder separately. This remainder is retained even during manual refills.
