Scope and age restriction
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.
Uniform connected hazard trees
Choose 3, 4 or 5 hazards on a 4×4 grid. Shared horizontal or vertical edges connect all hazards into a single graph, and that graph has no cycle. A solid 2×2 hazard block forms a cycle and is excluded. Straight connected rows of three hazards are permitted. The 52, 104 or 196 legal layouts respectively are equally likely; one is fixed for the entire round.
Wallet persistence and 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 data
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.
