The shelves are a mess. The books are mixed. You have one job: make every shelf a single color before time runs out.
SHELF SORT is a cozy, fast color-sorting puzzle. Tap or drag to swap two books, then watch the bookcase come together. Simple to learn, satisfying to finish, and full of new twists as you climb.
HOW TO PLAY
• Drag a book onto another book to swap them
• Tap two books to swap if you prefer
• Make each shelf one solid color to win
• Beat the timer — or start the level over
GROWING CHALLENGE
Early shelves are small and calm. Later ones get taller, wider, and trickier. Your progress is saved, so you can pick up right where you left off.
SPECIAL MODES
New rules unlock as you play:
• HIDDEN — a few books start gray. Their colors appear after a few seconds.
• ICE — frozen books cannot move until the ice melts.
• LOCK — locked books stay put until you swap the gold key onto them.
• PEEK — some books hide their color. Hold one to peek.
• QUAKE — now and then two free books swap on their own. Keep sorting around it.
Later levels mix several modes at once, so you have to plan, wait, and adapt.
