GAME GENRE - Puzzle games are almost excusively free games or/and games for smartphones. It's difficult to find a simple puzzle game sold at a high price. Tile matching is perhaps the most popular subgenre of puzzle games. Gameplay involves... well... matching tiles of some kind. The most popular tile-matching game is by far Tetris.
