Picture sudoku: logic fun without numbers

In our sudoku for kids, the boxes are filled with colourful symbols instead of numbers: 🐶 animals, 🍎 fruits or ⭐ shapes. That means even preschoolers who can't count or read yet can play along. Every puzzle has exactly one solution and is freshly generated for you – so there are always new sudokus. Kids who already know their numbers can switch to numbers – any time, even in the middle of a game.

1000 levels: a sudoku adventure with the lion

In level mode, your child travels with the lion through 20 worlds – from the savanna and the jungle all the way to the kingdom. Each world has 50 levels and gets a little harder: first 4×4, then 6×6 and later the classic 9×9 sudoku. Every level awards up to three stars, and progress is saved in the browser – no sign-up needed.
