Exactly two equally sized hazard islands
Choose 4, 6 or 8 hazards on a 4×4 board. Hazards must form exactly two connected components of equal size using shared-side adjacency only. Four hazards split into two pairs, six into two groups of three, and eight into two groups of four. Diagonal touching does not join components.
Every legal layout is equally likely. There are 126 layouts for four hazards, 248 for six and 288 for eight. The hidden layout is sampled once at the start and never moves after a choice. One captured stake covers the round.
Captured settings and visible cell probabilities
While idle, choose hazard count and 10, 20, 50 or 100 virtual coins. Start network captures those settings and deducts one stake. Hazard count, stake and refill controls stay locked during the round. Collection is unavailable before the first safe reveal.
There is no Auto queue, timed crash or cashout threshold setting. Each click reveals one eligible cell immediately. Sound is optional. The game does not animate a moving hazard or require a reflex action; the hidden layout remains fixed.
Local storage and page requests
The game does not require a customer account, identity document or bank information. Local storage explains the balance and fractional carry, but does not imply that every request made while loading the page stays on the device.
Font, analytics, hosting and CDN requests may transmit technical information such as IP address and request details. This guide promises no complete anonymity, precise retention period, absence of profiling or third-party data-sale policy. Those questions require the providers’ own information.
Optional use and personal limits
Participation is optional and offers no monetary prize. You may choose not to begin another round. Past outcomes do not make a fresh layout more favourable. A personal time limit does not change the layout distribution or conditional quote calculation.
This guide provides no clinical self-test, universal legal-age claim, confirmed external self-exclusion feature or promised transferable gambling skill. If play disrupts daily life, qualified local support may help. A free demo does not establish another product’s safety.
