About SudokuHint

A Sudoku coach that teaches you how to think — not just what to fill in.

The problem with most Sudoku apps

Almost every Sudoku app on the web is a great tool, but a poor teacher. When you get stuck, the hint button gives you the answer. Maybe it shows the technique name ("Pointing Pair", "X-Wing"), but it rarely explains how you were supposed to spot it on your own next time. You learn that there's an answer. You don't learn how to find one.

That gap is what SudokuHint fills.

How SudokuHint teaches

Every hint tells you which technique applies, where it applies, and why it works. If you want more depth, tap Explain to see the reasoning broken down. If you just want the move, tap Apply and the board updates automatically.

Over time, you start recognizing patterns yourself. That is the point.

What you can do here

  • Play unlimited puzzles at four difficulty levels, from Easy to Expert.
  • Use the Hint button to learn the next logical step, not just the answer.
  • Read the technique library to understand Naked Singles, Hidden Singles, X-Wing, and more.
  • Follow the beginner blog post if you are just starting out.
