Stakes, hazards and available choices
Choose 10, 20, 50 or 100 coins, default 20, and 3, 4 or 5 hazards, default 3. During a round, stake, hazard count, restore and a new round are locked; sound remains available. The random-choice button draws uniformly among eligible cells, including certainly safe cells; it does not necessarily choose the lowest hazard chance. Starting without enough balance shows a message without deducting a stake. There is no round pause or resume.
Probability after safe openings
Each safe opening removes layouts that would put a hazard there. For an unopened cell, safety probability is the number of remaining layouts in which it is safe divided by the total remaining layouts. The game uses that exact fraction. A button percentage is rounded to one decimal place and is not the full value used in pricing. Probabilities differ between cells and change with observations. A zero-probability cell is blocked; a probability-one cell is safe and does not increase gross value.
Collect after one safe opening
Collect becomes available only after at least one safe opening. You may collect current gross value or choose another eligible cell. A cell choice is blocked if current value divided by its safety probability exceeds 1,000 times the stake; equality is allowed. This limit applies to choosing a cell, not to Collect. After a safe opening, automatic collection occurs only when no eligible unopened cell has uncertain safety; certainly safe cells may still remain unopened.
Whole-coin credit and net change
On collection or automatic settlement, add raw gross return to old carry, credit the whole part and retain the new fraction below one coin. Net whole-coin change is credit minus the stake already deducted. The credit message describes whole coins, not complete gross return or profit. Finding a hazard gives zero raw return, leaves old carry unchanged and does not return the stake. Carry also remains when restoring the wallet.
Starting wallet and manual restoration
The starting wallet is 1,000 coins without cash value. Restore is manual, available only with no active round and a balance below 10. It sets exactly 1,000; it does not add 1,000 to the existing balance or clear carry. There is no automatic refill. If stake exceeds the wallet, starting shows a message without deducting coins; select a lower affordable stake.
Reloading forfeits an active round
Saved wallet, including zero, and carry remain in localStorage while the browser retains those data. Reloading or closing before collection discards the layout, opened cells and pending value: the stake stays deducted without refund, payout or resume. Reopening resets controls to stake 20 and 3 hazards. Ordinary settlement without reload retains the chosen stake and hazard count. The local wallet supplies no account recovery.
