A quieter corner of the Toca universe: Toca Boca Puzzle turns familiar characters and places into jigsaw boards. Pick a picture, scatter the pieces, and rebuild the scene one match at a time.
Puzzles are a different pace from the sandbox games - no stories to invent, just the calm of finding where each piece goes. Younger players get the easier boards; the bigger ones take real focus to finish.
Drag a piece and it snaps into place when it's close enough, which keeps it friendly on touchscreens. A good pick for winding down after the louder games. Free, in the browser, nothing to install.
