About Sudoku Sleuth
Different puzzles. Same investigative mindset.
Sudoku Sleuth is my home for variant sudoku. I pick the cases, solve them, and explain the logic one step at a time.
It is for curious minds who enjoy a good mystery. No speed runs, no shortcuts. Just the clues and where they lead.

The Investigation
Sudoku Sleuth began with a simple idea: every puzzle is a mystery. Variant sudoku takes the classic rules and adds a twist. New constraints. New patterns. New stories to uncover.
So I choose each case by hand and explain it plainly. Not just where the digits go, but why. The joy is in the discovery, and I want you to feel it for yourself.
Every case belongs to its setter. Their name is on the file, always.
A Different Way to Look at Sudoku
It is not just about numbers. It is about pattern, deduction and that quiet moment when everything fits.
I would rather show you the path than rush to the answer. Take your time. The grid will wait.
Every case takes
- Curiosity
- Patience
