Anybody played Tricky Towers? Seems like a good co-op game for relatively cheap ($7.50).
It's a lot of fun (at least on PS4). It's kind of like a reverse Tetris. There are a few different game types. Very enjoyable for local multiplayer, but has limited fun in the long run and probably limited fun for a single player setting. Also, the game types and controls are very simple which is nice for people of all skill types and ages (including kids).
