hey, you are the only GOG staff who likes a Puzzle Game.
Are we not going to see Good Old Puzzle games?
Seriously, Puzzles are freakin' AWESOME.
And all you guys who don't have any sort of Puzzle Game listed, get out from under a rock.
:D
Also, list your favorite Puzzle games, tell us why!

Well most adveture games are puzzle games at heart.
Lemmings is a classic of the genre, nothing funnier than having the first lemming dig a pit right under the entry point so they all fall down the hole as they come out. Oh there's also the solving of puzzles I guess but killing them was always more fun.
Not sure if it really counts but Bubble Breaker on windows mobile is quite good as a quasi-puzzle game

Logical, from the Amiga. That game was brilliant.
[EDIT] And Lemmings, of course. Thanks aliasalpha.

Lemmings also.
Also: Chips Challenge. (Which I have not seen since Win3.11)

Does minesweeper count as a puzzle game? Thats probably one of the worlds most played ones. Sure it sucks but TV has proved that popularity has nothing to do with quality...
One of the vista ultimate extras is a puzzle game called Microsoft Tinker, thats kinda fun, you have to get the robot through the puzzle in as few moves as possible and each action costs him some power
Another good puzzle games was Deflektor, there's a remake available here.

this is what is listed in her profile.
my favorite is puzzle league/tetris attack/panel de pon
there's also, dr. robotnicks mean bean machine, puyo pop, bejeweled.. all sorts.

Most puzzle games are adventure game, or have strong elements of it. So my wishes are on LucasArts.

Another classic Amiga puzzle game, which was also released for DOS: Pushover

Hey, don't call Puzzle Bobble (aka Bust-A-Move) girly, I got a NeoGeo arcade cabinet just for that :)
Good times, although it probably wasn't very good for the arcades: You could spend hours on it with just one coin.
Fahrenheit was a little too complicated for me... I usually found myself somewhere, with absolutely no hint on what to do next, but I can wholeheartedly agree on BrokenSword!
Funny how things come together: this thread's title shows a bug in the forum system: text is converted into entities and split afterwards, thereby splitting the entity itself.

Puzzle Quest is the best addition to the genre in years, in my opinion.
An 'oldie' that I always loved back in the day was the Smart Games series.

Actually, I'm surprised, because Fahrenheit is the easiest adventure game that I've played. It holds your hand right from beginning to the end of the story. There is one puzzle which needs some thinking (finding a book in library), rest feels like interactive story with guitar hero action parts (I hated those... ).
I've played GBA version of Broken Sword, and while it was easy adventure game it's story was very interesting for me, so I enjoyed it (Fahrenheits story has it's moments, but from something like 75% of the game it becomes bad, all of the atmosphere was ruined in 10-15 minutes...).

Does The Incredible Machine count as a puzzle game? That game was great fun.
