Every number is a clue.

Minesweeper across four-neighbour, eight-neighbour, hexagonal and wraparound grids. Choose a shape, lay a seeded field, and clear it with deductions you can trust.

Jirai is a Minesweeper rules engine and player for TypeScript and JavaScript. The core is plain functions; drawing, browser controls, a custom element and an optional React wrapper are separate imports. The package has no runtime dependencies and needs Node 22 or a modern browser.

Each picture is the real player, drawn by the package and taken from the demo with pnpm screenshots:readme, in light and dark.
