Learn the logic behind every Sudoku University hint
This is the companion site for Sudoku University, a from-scratch Sudoku solver, trainer and generator, currently in development for Steam. Everything here explains how the game teaches you to solve, not just where to click.
Confirmed visual direction
A trainer first, a solver second
Sudoku University is built around a full ladder of human solving techniques rather than a brute-force solver, so every hint teaches you a technique you can reuse on the next puzzle, not just an answer.
Staged, step-by-step hints
Every hint unfolds in four steps: technique, region, targets, then the full solution, so you can stop as soon as you see it, or read all the way through.
An honest difficulty scale
Puzzles are rated on an original, from-scratch engine calibrated against the community-standard Sudoku Explainer scale, described as SE-compatible, never as the official rating.
A generator you can trust
Every generated puzzle is checked for a single unique solution and re-verified as solvable within its target tier before it's ever served to you.
One colour language, everywhere in the game
The same four colours mean the same thing on every screen: the grid, every hint, and this handbook.
