Symbol Sudoku

Symbol Sudoku is a Sudoku puzzle game that replaces the numbers 1–9 with Greek symbols. Fill a 9×9 grid, divided into nine 3×3 boxes, so that no symbol appears more than once in any row, column or box.

Puzzle options

You can mark puzzles as favorites and generate new custom puzzles based on them. The game includes 250 puzzles across five difficulty levels, with the option to generate more based on your favorites.

You can enable or disable whether invalid candidates or pencil marks turn red, whether marks are removed when a placed value invalidates them, undo and redo, and alternate Greek symbols. You can also choose whether the grid starts with 1 in the upper-left or follows the numpad layout, starting in the lower-left.

Other features

The game has a minimalist design, keyboard shortcuts and relaxing music.
