Learn Sudoku: Technique Map

Stuck on medium puzzles? Learn one technique at a time with hints that show where to look and why. A free puzzle every day, no ads.

Stuck on medium puzzles? Sudoku isn't guessing. It's reading.

Learn Sudoku teaches one technique at a time, the way solvers actually think. When you get stuck, the hint doesn't hand you the answer. It shows where to look first, then names the technique, then points to the cells that prove it, and only then shows the result.

• A TECHNIQUE BOX TO FILL Your progress is a 3x3 box. Each chapter you finish puts a number in its cell. Solve a chapter's final puzzle without hints to earn its stamp.

• ONE TECHNIQUE FAMILY PER CHAPTER Rules, Full House, Hidden Single, Naked Single, Intersections (Pointing and Claiming), Pairs, Locked Pairs, Triples. Each chapter opens with a 30-second card and an intro puzzle that marks where the new technique applies.

• HINTS IN FOUR STEPS Where to look, which technique, why, and the result. You place the digit yourself. No lives, no timer pressure, and if you went wrong, rewind to your first mistake.

• A PUZZLE EVERY DAY One easy puzzle every day keeps your streak going. Optional reminders come only on days you haven't solved it.

• COMFORTABLE TO PLAY Big number keys in thumb reach, readable notes, Fill candidates, undo, dark mode, and layouts that hold up at the largest text sizes.
