The top 3 puzzle games for the NES (because there aren't that many.)

Tetris 2 - In my opinion, better than Dr. Mario. It has more block shapes than just one pill.

Puzznic - A rare and underrated puzzle game with about 100 fixed puzzles involving moving blocks and matching them up by color and making them disappear.

Pipe Dream - Make pipes so the ooze can ooze out in them instead of getting the board all messy.

Well, there you have it. What's your favorite NES puzzle games? I'd love to hear them.
