About CatDoku

CatDoku is a free puzzle game you can play directly in your browser — no download, no registration, just press play. It is the kind of game where one clever move can untangle a board that looked hopeless. On mobile the game switches to touch controls, so your progress is never tied to a desk. Like everything on LemonArcade, it is unblocked — it works at school, at work and on Chromebooks.

How to play CatDoku

Work out the logic of each layout and solve it before you run out of options. On mobile, the on-screen touch controls take over — tap to interact. Expect a gentle start and a real challenge soon after.

Tips to get better at CatDoku

• Mistakes are cheap: restarting a level early beats grinding a doomed position.
• Take a short break when a level resists you; fresh eyes solve puzzles faster.
• If you are stuck, look for the move that frees up the most space rather than the quickest win.
