I really like traditional puzzle game, try a few website to download them, but cant find it!! please hep me!

Maybe if you could be more precise what does "traditional puzzle game" means to you, people could give you suggestions.

Until then, take a look at this thread...
http://www.gog.com/forum/general/free_games_and_3rd_party_mods_the_updated_list/page1
...it have many free games listed.

I think he means jigsaw puzzle games, such as Jigsaw Boom. Not a free game though (but recommended for people who like jigsaw puzzles).

But yeah, "traditional" could also mean "in the tradition of old PC puzzle games", e.g. Crazy Machines and the like ...

Here are a few samples of my Puzzle link collection:
