The game and this website

Catdoku is a cat-themed logic puzzle for iPhone and Android. Place one cat in each colored region, row, and column, and keep cats from touching, including diagonally. You can try the interactive board before getting the mobile game.

This website and its blog are published under the Catdoku brand. The linked Google Play listing identifies the game's developer as Youngs.co. Our App Store listing links to the same game for iPhone.

How we explain the game

Our guides explain Catdoku's rules, feature conditions, and worked puzzle examples. Product details are checked against the available app and release information when we update a guide. Features that can change, such as Daily Challenge board sizes, should be read with the article's publication and modification dates.

We distinguish an actual screenshot from a reconstructed illustration. For example, our beginner deduction guide uses a Catdoku Level 2 layout to show why a single-square region must contain a cat. Our Daily Challenge guide explains the unlock condition, shared reset, and unfinished-board behavior.

Puzzle routines and outside sources

We recommend Catdoku as something enjoyable to play during a study break, a workday pause, or an evening routine. These are editorial suggestions. When an article discusses general learning or sleep habits, its sources support that discussion; they are not studies of Catdoku or proof of effects outside the game.

Corrections and support

We preserve an article's original publication date when revising it. Its modification date records the revision. For the next puzzle, get Catdoku for iPhone or Android.
