About Sudoku

Sudoku is a free thinking game you can play directly in your browser — no download, no registration, just press play. Every decision compounds: a small early advantage becomes a decisive one later. Touch controls are supported, so you can pick it up on mobile without losing anything. Like everything on LemonArcade, it is unblocked — it works at school, at work and on Chromebooks.

How to play Sudoku

Out-think your opponent: manage your resources, anticipate their plan and strike where it hurts. On mobile, the on-screen touch controls take over — tap cell then number. Expect a gentle start and a real challenge soon after.
