I'm not exactly sure what to call these games, and I only know of some examples like: Mah Jong solitaire, Sudoku, Bejeweled, Mini golf, Tetris variants, word puzzles, club pengiun--I think you get the general idea.
I like Mah jong solitaire, Bejeweled and word puzzles such as Bookworm. I never considered myself a golf lover, but I really do like mini-golf games.
What's your favourite game?
