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.
Three occupied rows with distinct counts
Choose6,7 or8 hazards on a4×4 board. Exactly three rows contain hazards; their positive hazard counts are all different. The fourth row is empty. Counts are1/2/3 for6;1/2/4 for7;1/3/4 for8, in any row order. All2304/576/384legal layouts respectively are equally likely andfixed during a 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.
External claims remain unverified
A matching brand, professional design, search result or HTTPS connection does not verify ownership, authorisation or safety. Match any claim against an independent regulator register, including entity, current status, scope and listed domains. No operator licence or service is endorsed here.
Local coins and default settings
Local demo coins cannot be exchanged for money, withdrawn or used as evidence of an operator balance. Settings return to the interface defaults on reload; settled wallet and fractional carry persist. The game is not an authentication or external-security test.
