GridMew5×5 cat logic puzzles
Original puzzles, ready for a little quiet thinking.
This collection contains 80 original 5×5 boards. Each has 5 connected regions and needs 5 cats. The compact grid keeps a whole position easy to inspect; the reasoning still depends on candidates and region shape. Size and difficulty are separate: all three reasoning groups are available in this collection.
Difficulty reflects the reasoning, not just the board size.
