It depends on what the game is trying to achieve. Tetris is probably perfect as is Minesweeper. Perfect in that they are the game they are supposed to be. Whether a person enjoys the game or not is a different story.
Here are the first three definitions from dictionary.com:
1. conforming absolutely to the description or definition of an ideal type.
2. excellent or complete beyond practical or theoretical improvement.
3. exactly fitting the need in a certain situation or for a certain purpose.
A game can match each one of those definitions. Many do, especially the old/ancient non-video games.
