Own-site age and demo rules

These rules describe only this original virtual game. This guide does not determine legal availability of an external service, certify its fairness or promise income. The own-site 18+ restriction is not a statement about every jurisdiction’s legal age.

One diagonally connected group

Choose 3, 4 or 5 hazards on a 4×4 board. All hazards form one connected component using diagonal corner-to-corner steps only. Horizontal and vertical edges do not connect hazards. Every hazard is reachable from every other hazard along diagonal steps; all lie on the same checkerboard colour. All 32, 50 or 52 legal layouts respectively are equally likely, and one stays fixed throughout the round.

Persisted wallet and manual refill

Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its already deducted stake. Outside a round, refill restores 1000 coins when balance is below the smallest stake; it does not add 1000 or reset fractional carry. Hazard count, stake and refill are locked during play.

Technical requests and data limits

There are no account, payment or identity-document forms here. Fonts, the visit counter, server and CDN requests can expose technical data including IP and browser details. Complete anonymity, third-party data use and cookie lifetimes are not established. Clearing cache alone may leave localStorage intact.
