21. Mahjong Solitaire

Mahjong Solitaire doesn’t do anything more than what its title implies. It’s a tile matching game at its heart, and it pulls from the classic game of Mahjong for its symbols and you semi-consciously click on matching tiles to eventually clear the board. Yeah, you can select different themes or avatars to display in the background, but there’s nothing here to leave any sort of impact intellectually that you want in the best kinds of puzzle games.
