Get today's puzzle at any of six difficulties — from Beginner to Diabolical — on a board you can actually play, or generate a fresh puzzle whenever you want one. More importantly, learn how to solve: every hint names the real technique in play and teaches you to spot it yourself, drawn from our Sudoku University teaching program and its twenty-technique glossary.

Skills 2
- daily-sudoku
Play a sudoku puzzle in the conversation — fetch today's daily edition or generate one at a chosen difficulty, then help the player through it with real solving logic. Use when someone wants to play sudoku, asks for today's or a new sudoku, or is working through a sudoku board and needs a hint, a check, or an explanation of why a move works. Do not use for crosswords, wordle-style games, word ladders or other puzzle types.
- sudoku-coach
Teach sudoku solving technique — explain what a named move is, the tell that says to look for it, and how to apply it, drawn from a twenty-rung glossary that runs from naked singles to unique rectangles. Use when someone asks what a sudoku technique is, how to spot an X-wing or swordfish, how to get better at sudoku, what to learn next, or why a solving rule works. Do not use when they are working a specific board and want their next move — that is the daily-sudoku skill.
