About Classic Sudoku
Classic Sudoku, presented by the popular YouTube channel Cracking The Cryptic, brings a curated collection of hand‑tested puzzles to PC. Hosts Simon Anthony and Mark Goodliffe, both seasoned World Sudoku Championship competitors, oversaw the selection to ensure each puzzle offers a thoughtful solving journey.
Players begin with zero stars and earn them by completing puzzles; accumulating stars unlocks additional challenges. With 40 launch puzzles and a steady flow of new levels, the game promises a long‑term, solo experience for solvers of all skill levels.
01 / THE GUIDE
Puzzle Collection
The launch package contains forty carefully chosen Sudoku puzzles that span a wide difficulty range. New puzzles are added at a rate of five per month for the first year, ultimately reaching one hundred levels.
Each puzzle had to pass a rigorous human‑only play‑testing process, ensuring that the solving path was intentionally crafted rather than generated by a computer algorithm.
- Compare early‑level puzzles with later ones to notice how technique demands increase.
- Track which difficulty feels comfortable before tackling the newest monthly additions.

Progression System
Players start with zero stars and earn stars by solving puzzles. The more stars you collect, the more puzzles become available, encouraging continued play.
Star accumulation does not guarantee instant access to every puzzle; unlocking follows the game's internal pacing based on solved counts.
- Focus on completing puzzles fully to maximize star gain per session.
- Keep an eye on your star total to gauge when new puzzles will appear.
