Nookdoku: Brain Puzzle Games

Find a cozy spot for every cat in Nookdoku, a relaxing logic puzzle game with colorful grids, daily challenges and offline play. Think through each move and enjoy that satisfying moment when the solution clicks.
If you enjoy Sudoku-style deduction and Queens puzzles, make yourself at home. Nookdoku brings a playful twist to grid puzzles: instead of filling in numbers, you find the right place for every cat.
The rules are simple:
- Place exactly one cat in every row.
- Place exactly one cat in every column.
- Place exactly one cat in each colored region.
- Keep cats apart: they cannot touch, even at the corners.
Tap to mark spaces with an X, double-tap to place a cat, or drag to mark several cells at once. Look for clues in the colored regions and use each discovery to work out your next move.
Make Nookdoku part of your daily puzzle break. Explore 100 campaign puzzles, from compact 4x4 grids to larger 9x9 boards. Return for the daily challenge and build your puzzle streak. Whether you have a few quiet minutes or time for a longer session, these brain teasers give you a reason to pause and think.
Need a little help? Get a hint that explains a logical next step, so you can understand the reasoning behind it. Undo your manual X marks when you want to rethink a move, or enable automatic marking to cross out spaces ruled out by each cat you place.
Take your puzzle nook with you. Puzzles and hints work offline, and saved progress lets you pick up where you left off. With no time limit, you can take each board at your own pace.
A guided first puzzle introduces the rules, while cute cat illustrations and a warm, colorful style make every board feel welcoming. Adjust the sound and use reduced motion to make your puzzle break more comfortable.
From your first deduction to the last cat on the board, Nookdoku turns simple rules into satisfying brain puzzles.
Find your nook. Solve a puzzle. Make room for every cat.
