Hand-drawn Logic Puzzles
Six kinds of logic puzzle in a paper notebook. Every one solvable by reasoning alone.
One cat per row, column and colour — never touching.
9×9 numbers, emptier every level.
Fill squares by the clues, and a cat appears.
Half and half per line, never three in a row.
Each dashed cage must add up to its sum.
One path, in order, through every square.
No rush — the cats can wait.
