Sudoku Gaia & Solver

Classic Sudoku with a clean, simple interface.

Enter numbers in two ways: via on-screen buttons or the numeric keypad.

Choose from three color themes: blue, brown, or gray.

Five difficulty levels make it enjoyable for both beginners and experienced players.

Every puzzle is randomly generated with a unique solution, and you can even create symmetrical layouts.

Your progress is always saved, so you can return to any unfinished game at any time.

Use the “Hint” button to reveal a digit — but be careful, each of the five hints reduces the game’s difficulty level. (Hints are disabled in “Easy” mode.)

The entire game is in English and completely free to play.
