Whats the best Puzzle game ever?

[okr]

I didn´t claim Tetris to be the greatest game of all time, but I think it´s the most influential game design ever created.

Anyway:
Other great “modern” puzzle games are Zoo Keeper, Puzzle Quest & Meteos. And Lumines - which I´ve never played - looks great, as well. All Tetris derivates, btw.
