The board and complete hazard layouts
The 4 × 4 board has cells numbered 1–16 in row order. Before starting, choose 3, 4 or 5 hazards. Exactly one hazard must have no other hazard a chess-knight move away: two rows and one column, or one row and two columns. The other hazard groups need not all be connected. There are respectively 232, 412 and 1,288 complete layouts satisfying that rule. The game samples one of the chosen count’s complete layouts with equal probability and keeps it fixed for the whole round. Hazards are not placed independently in equally risky cells.
Conditional chances and the gross multiplier
After safe reveals, retain only layouts consistent with every revealed safe cell. A cell’s safety probability p is the fraction of those remaining layouts that avoid that cell. Only uncertain cells with 0 < p < 1 can be selected; revealed cells, proven-safe cells and proven hazards are disabled. The gross multiplier M is 0.97 × initial layout count ÷ remaining layout count. On a safe reveal it becomes M/p. Multiply the captured stake by M to obtain the raw gross return; this includes returned stake and is not net profit. Displayed safety percentages are rounded to one decimal place, while calculations use the unrounded ratios of layout counts.
Collecting, the cap and automatic settlement
Manual collection is available after at least one safe reveal, and is optional then. A prospective multiplier greater than 1,000 is blocked before any reveal, without changing the hidden layout, observed cells, quote or wallet; equality is allowed. Such a cell remains uncertain even though that attempted move is blocked. Automatic collection occurs only after a safe reveal when no uncertain cell remains anywhere on the board. It does not occur merely because all remaining uncertain moves would exceed the cap. A hazard ends the round with zero gross return; you cannot collect an earlier quote afterward.
Stake, hazard count and active-round controls
Choose a stake of 10, 20, 50 or 100 play coins; the default is 20. The default hazard count is 3. Starting deducts one captured stake for the entire board. During that round you cannot change the stake or hazard count, restore the balance or start a second round. You can select uncertain cells, subject to the prospective-multiplier check, and collect after a safe reveal. Sound remains available. The game does not automatically queue more rounds.
Integer payment and fractional carry
When a round settles, add the previous fractional carry to captured stake × gross multiplier, credit the integer part to the wallet and retain the fractional remainder for later settlements. A zero-return round preserves the old carry. Balance and carry are stored in browser localStorage and survive manual restoration and reload while that site data remains. Carry is an unpaid fraction of a virtual-coin payout, not cash, a score or a clue about hazards.
Reloading and clearing browser data
Reloading an unfinished round leaves the already captured stake deducted and ends that round without refund, payout or resume. The saved wallet remains, but the hidden board and safe picks do not. Controls return to stake 20 and 3 hazards. Clearing cached resource files alone may leave localStorage intact; clearing this site’s data can remove the saved balance and carry. There is no account-based wallet recovery or synchronization with another device.
Frequently asked questions
Is the hidden layout redrawn after a safe pick?
No. One uniformly sampled complete layout stays fixed for the round; only the compatible-layout calculation changes.
Can I collect an earlier quote after hitting a hazard?
No. A hazard ends the round with zero gross return. Previous fractional carry is retained.
When can I collect?
After at least one safe reveal. Manual collection is optional; automatic collection requires no uncertain cell remaining.
Can I select a proven-safe cell?
No. Only cells whose exact safety probability is strictly between zero and one can be selected. Revealed cells and proven hazards are also disabled.
What if the next multiplier exceeds 1,000?
The attempted move is blocked before reveal without changing the round. A multiplier exactly equal to 1,000 is allowed. Cap-blocked uncertain cells do not by themselves trigger automatic collection.
Does restoration add 1,000 coins?
No. While idle with balance below 10, manual restoration sets the balance to exactly 1,000 and preserves fractional carry.
Can an unfinished round resume after reload?
No. Its captured stake remains deducted, without refund or payout, and the round cannot resume. The saved wallet remains while site data is retained.
Does 97% guarantee my result?
No. Expected gross return and recorded sample simulations are not a win probability or a promised round or session result.
Is the displayed multiplier the coin payout?
No. Multiply the captured stake by the gross multiplier. Settlement includes prior fractional carry, credits the integer part and saves the remainder.
What settings return after reload?
Stake 20 and 3 hazards. During an active round stake, hazard count and restoration are locked; sound remains available.
Does a saved zero balance reset on reload?
No. Saved zero is retained. The 1,000-coin initial balance applies only when there is no saved wallet.
Does account-free play guarantee anonymity?
No. The page requests Google Fonts and the Statinside 44 counter. Possible server logs and other processing are not excluded.
