Amazing Sudoku
A beginner-friendly 9×9 sudoku with hints and undo, so a wrong turn never sinks the whole grid.

Controls
Select a cell and choose a number to place it; draft your moves, undo a slip, or call a hint if you get stuck.
How to Play
Amazing Sudoku takes the classic 9×9 puzzle and adds a few helping hands. Fill the grid so each row, column and 3×3 box holds the digits 1 to 9 once, drafting moves as you go and undoing anything that does not sit right.
If you are finding your feet, our step-by-step guide explains the approach clearly. With hints and undo on tap, it is a forgiving place to build confidence.
Tips & Tricks
- Draft uncertain moves first, then confirm them once the surrounding cells line up.
- Reach for undo the moment a placement feels wrong, before it spreads into other cells.
- Use a hint to learn the technique behind a tricky spot, not just to fill it in.
