Occupied rows have odd hazard counts

Choose 3, 5 or 7 hazards on a 4×4 board. Each occupied horizontal row contains an odd number of hazards: one or three. A row has only four cells, so five hazards in one row is impossible. Empty rows are allowed and columns have no quota.

Every legal layout is equally likely: 272 layouts for three hazards, 768 for five and 768 for seven. The hidden layout is sampled once at the start and never changes after a choice. A single captured stake covers the whole round.

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.
