A quiet place for one good puzzle.
iPlay Sudoku is free, requires no account and never interrupts a puzzle.
Endless puzzles
Four difficulty levels are generated continuously and every puzzle has one solution.
Ads stay outside
Advertising supports the site, but it belongs outside the board or after completion.
Explain the logic
Our academy teaches one useful method at a time in plain language.
How our guides are prepared
Our guides use AI-assisted drafting and translation. We check the logic of the worked examples before publication, distinguish deductions from answer reveals, and revise explanations when errors are reported. Local candidate tables illustrate a deduction; they are not presented as complete Sudoku puzzles. These are puzzle-solving guides, not medical advice.
