Book Sort: Color Puzzle

Sort books by color onto wooden shelves. Book Sort: Color Puzzle is a calm color sort puzzle set in a pixel night library.

Tap a shelf to lift the books on top. Tap another shelf to set them down. Books land only on an empty shelf, or on a shelf whose top book is the same color and still has room. Fill a shelf with one color to finish it. Clear every shelf to win.

209 levels start with a short lesson and grow into longer evening puzzles. Twelve book colors each carry their own cover mark, so a shelf is readable at a glance.

What you will find:
- Hidden books, wrapped in cloth until the books above them move
- Locked shelves that open once another shelf is finished
- A return cart, where one book can wait out of the way
- Undo and restart on every level
- A hint when you want the next step
- Stars for finishing close to the target number of moves

Play without an account. Your stars stay on this device.

If you like color sort puzzles, the rhythm will feel familiar: same color together, one shelf at a time.
