Independent boards and conditional prices
Independent enumeration checks all 65,536 binary 4×4 boards for the chosen hazard count, exactly one main-diagonal hazard and a diagonal companion for every hazard. It compares the support and conditional cell probabilities with the actual source. At least one million actual-source rounds are simulated for each mode.
This is evidence about this original demo only. It does not establish an outside publisher, licence, certified RNG, payment feature, legal permission or app safety.
Exactly one main-diagonal hazard with companions
Choose 3, 4 or 5 hazards on the 4×4 board. Exactly one hazard lies on the main diagonal from top-left to bottom-right. Every hazard, including that one, must have another hazard one row and one column away. Orthogonal adjacency alone does not qualify.
The anti-diagonal has no quota and separate diagonal-connected groups are allowed. Legal supports contain 6, 40 and 120 layouts for three, four and five hazards. Sample uniformly once; never relocate. A1 and D4 are safe in every supported mode: a corner hazard would require its diagonal neighbour, creating two main-diagonal hazards.
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.

What makes a hazard layout legal?
Choose 3, 4 or 5 hazards on the 4×4 board. Exactly one hazard lies on the main diagonal from top-left to bottom-right. Every hazard, including that one, must have another hazard one row and one column away. Orthogonal adjacency alone does not qualify. The anti-diagonal has no quota and separate diagonal-connected groups are allowed. Legal supports contain 6, 40 and 120 layouts for three, four and five hazards. Sample uniformly once; never relocate. A1 and D4 are safe in every supported mode: a corner hazard would require its diagonal neighbour, creating two main-diagonal hazards.
How is the chosen cell priced?
After the opened safe cells are known, let N be the number of legal layouts consistent with that history. For an unopened cell let K be the number of those layouts where it is safe. Its safe probability is K/N. Each eligible cell shows that probability; it is not a generic remaining-safe-cells ratio. The quote starts at 0.97. A safe reveal changes quote q to q×N/K, using the probability of that very chosen cell before revealing it. A hazard ends the round with zero return. Collect returns captured stake times quote, with fractional carry. The identity (K/N)×(q×N/K)=q explains 97% expected gross return for choices using revealed information. This is not a win probability or a guaranteed session return.
