Any old school Puzzle games you enjoy? [Any puzzle games]

When it comes to puzzle games like side-scrolling and such, Tetris was the only puzzle game I can get into and I play just about all Tetris games. I think Pokemon Puzzle League was the last great side-scrolling game I enjoy. Well these are my puzzle games I played years ago:

• Tetris
• Tetris 2
• Tetris World
• Pokemon Puzzle League
• Dr. Mario
• Dr. Robocknit's Mean Bean Machine

The only two that come to mind are Super Columns and Dr. Robotnik's Mean Bean Machine.
