How to play
The goal of the game is to place one cat in each row, each column, and along both main diagonals of the grid.
Basic rules:
• Cats don't like crowding! Two cats cannot be in adjacent cells (horizontally, vertically, or diagonally).
• There must be exactly one cat in each row and each column.
• There must also be exactly one cat on each of the grid's main diagonals (corner to corner).
Controls:
• Single click/tap — place or remove an X (mark a cell where a cat cannot be).
• Double click/tap — place a cat.
• Press and drag — quickly fill multiple cells with Xs.
Useful features:
• Auto-X: when you place a cat, all surrounding cells are automatically marked with Xs.
• Hints and Undo — help you find the correct solution if you get stuck.
