Best puzzle games

[Freegamer]

I'm in a puzzle games mood, now playing Adventures of Lolo 3 (NES). It got me hooked and I'm pretty sure I'll play it to the end, hoping I won't get stumped by some hard level .

So, I was wondering, what are the puzzle games you enjoyed the most?

My list so far:

Adventures of Lolo 1, 2 and 3 (NES)
Fire 'n Ice (NES)
One Step Beyond (Amiga)
Pushover (Amiga)
The Lost Vikings 1 (Amiga, then replayed on Genesis for the extra levels)
The Lost Vikings 2 (SNES)
Troddlers (Amiga)

The daddy of them all is Boulderdash and that was one of my all time favourite games.

Unfortunately I had to give up on AoL 3. It was fun for a while, but in some levels (especially 13) the puzzles were a bit frustrating.

After that, I played Little Magic (SNES). Very good game, definitely recommended.

Bejeweled is a fun puzzle game, so is Huniepop even if it has visual novel elements added into it. The puzzle mini-game is the best part. Tetris is always good for a puzzle game.
