Sudoku Through Time
Calm sudoku through the ages
Proper sudoku, with nothing in the way
- No ads, ever, free or paid.
- Every puzzle has one solution. No guessing.
- No lives, and hints that teach for free.
Five ages of history, and The Mirror Age
Each age of history is its own difficulty, so the journey is the challenge. Begin in Stone Dawn, then travel on through Ancient Egypt, The Scriptorium and The Clockwork Age to The Celestial Age, where the hardest puzzles wait. Every age has 400 puzzles and its own scenery.
Beyond them lies The Mirror Age, a bonus world of 200 X-Sudoku puzzles, where both long diagonals must hold every number from 1 to 9 as well.
The first three ages are free for good. One purchase, once, unlocks The Clockwork Age, The Celestial Age and The Mirror Age, and every world we add later.
