How to Play Kidoku
Kidoku is a picture sudoku made just for kids! Instead of numbers, you fill the grid with fun pictures like fruits, animals, and stars. Each picture must appear exactly once in every row, column, and colored box.
Look at the Grid
Some pictures are already placed in the grid. These are your clues! Use them to figure out where the missing pictures go.
Tap a Cell, Pick a Picture
Tap any empty cell, then choose a picture from the palette below the grid. The picture will appear in the cell!
Follow the Rules
Each picture must appear exactly once in every row, every column, and every colored box. If you make a mistake, the cell will turn red!
Pick a Theme
Choose from themes like Fruits, Animals, Ocean, Space and more! Each theme has its own set of fun pictures to play with.
Fill the Whole Grid
Once every cell is filled correctly, you win! Try different themes and grid sizes to keep the fun going!
What is Kidoku?
Kidoku is a kid-friendly version of Sudoku, one of the world's most popular puzzle games. Instead of using numbers 1-9, Kidoku uses fun, colorful pictures that kids love — like fruits, animals, flowers, and space objects.
Sudoku puzzles are fantastic for developing logical thinking, pattern recognition, and concentration in children. Kidoku makes these benefits accessible to kids as young as 4 years old with its smaller, easier grid sizes.
Tips for Young Puzzlers
Start with 4x4
Begin with the smallest grid size. It uses just 4 pictures and is perfect for first-time players!
Look for Easy Wins
Find rows, columns, or boxes that only need one more picture. Those are the easiest to solve!
Check All Directions
Before placing a picture, check its row, column, AND colored box. Make sure it's not already there!
Use the Eraser
Made a mistake? No worries! Select the eraser from the palette and tap the cell to clear it.
