Sort Till You Sleep is a cozy first-person sorting game. A house is buried under 3,810 toy sheep in 190 costumes, and the player carries them by the armful to the shelves that match their costumes until every sheep is home, then goes to sleep. There is no timer and no fail state. Finished shelves pay out balls of wool that buy upgrades at the Knitting Nook, such as carrying more sheep at once or reaching farther. Ringing a bell starts one of nine bedtime mini games, including tossing sheep through a dream cloud, counting sheep over a fence, catching wishing stars and pairing socks; each first win teaches a sorting skill. Small environmental mysteries are scattered through the rooms, and ten wolves in sheep's clothing hide among the flock. One continuous playthrough lasts about 3-4 hours.
