Shoji - Sudoku Master

Learn Sudoku properly, from your first naked single to X-Wings and Swordfish. No ads, ever.

Most Sudoku apps hand you a grid and wish you luck. Shoji teaches you how to actually solve it.

Work through a complete curriculum of solving techniques, starting with the basics and building to the patterns experts rely on. Each technique gets a full lesson: an explanation, guided practice where the board walks you through it, and free play to prove you've got it. Then face a Challenge that combines everything you've learned.

What's inside

• Lessons — every technique from cross-hatching and naked singles through hidden pairs, pointing pairs, triples, wings, and fish patterns like X-Wing and Swordfish • Daily puzzles — a new board every day at every difficulty you've unlocked • Practice — focused sets to drill what you've just learned • Specials — Sudoku variants with new rules: Knight's Move, King's Move, Non-Consecutive • Craft — generate unlimited puzzles targeting any single technique you want to sharpen • Endless — an ongoing stream of puzzles that quietly steers you toward whatever you're weakest at

No ads. No pop-ups begging for a rating. No fake urgency, no streak guilt, no energy meters. Just a clean board, honest feedback, and a path from beginner to master.
