Sleepless nights. Little sparks of insight. Sleepy Cats is a logic puzzle about finding the right order to send every cat to sleep. MATCH THE NUMBER Tap a cat when its number matches the number of cats directly above, below, left and right. The sleeping cat disappears, and the others move with gravity. Every move changes what comes next across 2000 puzzles. CURIOUS CATS, CLEVER TWISTS Meet cats that sleep together, look only sideways or vertically, wear pajamas, or stay anchored in place. Other cats change how counting and movement work. Learn new rules gradually, then discover how they combine. PLAY AT YOUR OWN PACE There is no time limit. Undo a move, restart or use a hint to try another idea. You can leave a puzzle for later and try another, except in some introductory stages.
