About Paw Sudoku

Paw Sudoku is the classic number puzzle from Pet Love Arcade. Fill the grid so every row, every column and every box holds each number exactly once. It starts with a tiny 4x4 grid that anyone can solve, then a 6x6, then full 9x9 sudoku that gets harder level by level, with fewer starting numbers and a clock, up to a hard final puzzle. Every puzzle has exactly one solution.

How to play Paw Sudoku

Tap an empty square, then tap a number on the pad (or type it). A wrong number costs one of 3 hearts. Switch on the pencil to write small notes in a square. Matching numbers and the row, column and box of the selected square light up to help you. Finish a row, column or box for bonus points. Solve a puzzle to win a heart back. Solve all 5 to win.

Tips: start with the rows, columns and boxes that already have the most numbers. If a number can only fit in one square of a row, column or box, it goes there. Use pencil notes for squares with two or three options and clear them as the grid fills in. A wrong guess costs a heart, so look for a sure number first.
