18G APK questions and browser access

Use the home-page simulator directly in the browser. This guide does not provide an APK download or claim to have inspected a downloaded package. There is no package-identity or software-security certification here.

A four-by-four board is chosen uniformly from legal placements of the selected 3, 4 or 5 mines. Within each row, mines form at most one contiguous block; an empty row is allowed. The board remains fixed during the round. The simulator is not presented as a copy of a separate commercial app.

After safe reveals, gross quote = 0.96 × captured stake × initial legal-board count / remaining compatible-board count. Each safe reveal keeps only boards where that cell is safe. The captured stake is fixed at start and does not grow as cells are revealed. A mine ends the round with zero return. Cells that are certainly mines are disabled. A cell is also disabled if its safe outcome would quote more than 1,000 times the stake. When no eligible reveal remains, the current quote is collected automatically. Manual collection becomes available after the first safe reveal.

The initial wallet is 1,000 virtual coins. Whole balance and fractional carry persist locally. Low idle balance can be manually set back to 1,000; unfinished reloads are not refunded.

The page uses localStorage for wallet and carry. Fonts and the Statinside counter can involve browser requests to external services. No demo login does not prove anonymity or absence of other processing.

A similar name or domain does not establish the identity or permissions of an outside app. This guide supplies the browser demo, not installation instructions or an endorsement of another package. Demo coins cannot be withdrawn as money.
