Cat Naptime: Stacking Puzzle

Move the sleepy cats to the right and tuck them in. 100 levels across five sunlit rooms!

Purrfect Balance is a cozy physics puzzle about moving squishy cats to the right side of the room and stacking them into a perfectly balanced nap tower.

Pick up the cats on the left one at a time and set them down on the right. A cat placed on the right falls asleep and can't be moved again. Get every cat asleep on the right and hold still for 5 seconds to clear the level!

FEATURES • 100 hand-tuned levels across 5 tiers, from Kitten to Legend • Jump into any tier right away — skip the easy ones and go straight for the hard puzzles • Heavy gold-bell cats, slippery ice cats, seesaws, pegs and more physics tricks • Adorable reactions: cats yelp when they fall, squish when bumped, smile when they land safely and doze off • Five sunlit rooms — living room, kitchen, loft, study and a Korean hanok — each with its own music • New levels arrive online, no app update needed • Made a mistake? Undo your last move and try again

A remake of the classic iPhone physics puzzle Stackus, by its original developer.
