Four neighbours
Orthogonal Jirai counts only the cells above, below, left and right. It is a separate rules variant from the eight-neighbour square board.

THE RULES ARE SMALL
Read. Mark. Uncover.
- Open a cell. A number tells you how many neighbouring cells hide a mine. Empty ground opens out on its own.
- Mark what you know. Right-click, hold, or choose Mark. Flags are notes, not proof; placing one doesn’t change the board.
- Clear the field. Open every cell without a mine to finish. When flags match a revealed number, tap it to open the neighbours together.
Six neighbours
Hexagons change the patterns: no diagonals, and six directions to read.
No outside edge
Wraparound joins left to right and top to bottom. A corner has eight neighbours too.
A fair deduction
No-guess fields are verified from the opening you choose. The mines stay fixed after that.
