Sudoku

Sudoku is fantastic brain training, but the classic 9x9 grids are often too overwhelming for small children. That's why I built a child-friendly version that gently introduces them to the world of logic puzzles.

I wanted something that is immediately fun without having to explain complicated rules. Just tap, pick a number, and get feedback.

What's inside?

• 3 Levels: Tiny (3x3), Mini (4x4), and Big (5x5).
• Child-friendly Design: Big numbers, fixed colors, and fun animations.
• Immediate Feedback: Wrong numbers shake, right numbers go "Ding!".
• Reward: A confetti shower celebrates every solved puzzle.

The game runs directly in the browser, perfect for a quick session on the iPad or phone.
