Thermo Sudoku Puzzles | 100 Logic Challenges, Easy to Expert (Digital Download)

You can only make an offer when buying a single item

Highlights

100 thermometer sudoku puzzles in a single instant-download PDF — print at home and solve again and again.

Thermo sudoku adds thermometers to classic sudoku: along each thermometer the digits must increase from the bulb to the tip. Graded gently from easy to expert so you can warm up and then really dig in.

WHY THESE ARE DIFFERENT
Every puzzle is proven to have exactly one solution — and to be solvable by logic alone, with no guessing. So many variant-sudoku books are full of ambiguous or unsolvable puzzles; ours are verified before they ever reach you. Proven, not promised.

- Large-print grids with a dedicated working area on every page
- Full answer key for every puzzle
- A print-ready PDF (US Letter), one puzzle per page
- Instant digital download — print as many copies as you like, for personal use

GREAT FOR
