Game Setup and Tile Mechanics

Each round starts with a stake of 10, 25, or 100 virtual coins, defaulting to 10. Exactly three mines are uniformly distributed across 16 tiles. You reveal tiles individually, and previously opened tiles cannot be selected again. The game ends immediately if you hit a mine, resulting in zero return.

Conditional Probability and Risk

The probability of surviving k reveals is determined by the remaining safe tiles. After k safe tiles are revealed, the chance of the next tile being safe is (13-k)/(16-k). You must decide whether to continue risking your stake for a higher multiplier or collect your winnings. The risk increases significantly with each additional tile revealed.

Payouts and Gross RTP

Gross return includes your original stake and is calculated as stake times 0.96 divided by the survival probability at k. The expected gross RTP is 96% for every fixed collecting depth. For example, collecting after one safe tile yields a multiplier of approximately 1.18. The house edge is 4%, representing the long-term statistical advantage.

Wallet and Settlement Rules

A captured whole stake is deducted once at the start. Gross return includes the stake, and any fractional carry is saved separately. Manual restoration is available only when idle and below 10 coins, setting the balance to 1000. Reloading the page resets the board and loses the unfinished round without refund or resume.

Frequently asked questions

How is the payout calculated in Trilha Terracota?

Gross return equals the stake multiplied by 0.96 divided by the survival probability at the number of safe tiles revealed. The prior fractional carry is added to the gross return; the total is rounded down to whole coins and the new remainder is saved.

What happens if I reload the page during a round?

The debit persists immediately, but the unfinished round state is not saved, resumed, or refunded. Reloading resets the stake selector to 10 and requires a new round to begin.

Is there an automatic cash-out feature?

The game automatically collects after thirteen safe tiles. Before that, you can choose to collect after at least one safe tile; there is no auto-bet feature.
