Catdoku vs LinkedIn Queens
The same kind of deduction. A different place to play.
Which one fits your play?
Both puzzles ask you to place one character in every row, column and colored region, without letting two touch. Catdoku brings that logic to a cozy cat-themed browser game on FoolFish. LinkedIn Queens builds a daily puzzle into LinkedIn’s games and social routine.

A small board can give you a very good deduction.
Every cat takes a row, a column and a color region. It also rules out the cells that touch it. The interesting move is often not the next cat: it is the cell you can confidently exclude. Catdoku turns those overlapping constraints into a clear, colorful puzzle.
Play CatdokuLearn the local rule before the whole solution.
Start from one placed cat. Its row and column cannot contain another cat, and neither can its immediate neighbors. Work through these small exclusions, then look again at each region. If a region has only one legal cell left, you have earned the next placement.

Choose your setting, keep the deduction.
If Queens introduced you to colored-region logic, Catdoku is another way to enjoy that style of problem. Its cats change the atmosphere, not the meaning of “one per region.” Catdoku is published on FoolFish with its own game identity; it is not an official LinkedIn game.

Frequently asked questions
Are Catdoku and Queens the same game?
They use closely related placement constraints, but they are separate products. Catdoku is the cat-themed game by Sudokuer published on FoolFish; Queens is a LinkedIn game.
Can two cats touch diagonally?
No. Catdoku’s non-touching rule includes diagonal neighbors. A placement can satisfy the row and region constraints and still be invalid because another cat is too close.
Is Catdoku a standard Sudoku puzzle?
No. You place cats rather than digits, and its colored regions and non-touching rule define the puzzle. Standard Sudoku instead requires a complete set of digits in every row, column and box.
Which is better for a daily routine?
Queens offers a shared daily puzzle. Catdoku provides its own points, streak and multiple board sizes. Choose the experience you want to return to.
Does signing in give Catdoku a cloud save?
This Catdoku version does not offer account cloud saving. Keep that in mind before changing browsers or devices.
