Logic as in puzzle games?

For platform games, you can get Trine. There are some physics-based platform puzzles in it too.

It costs 20 euros on Steam and is in the Humble Bundle pack, if you pay more than average (Pay what you want) which is now about 5 dollars too. (www.humblebundle.com)

Other platform(ish) games, just quoting from my Steam libary:
- VVVVVV (Demo available online, as a Flash-based game)
- Portal (Demo available)
- Portal 2
- Braid (Puzzle Platformer) (Demo available)

Puzzle:
- Crayon Physics Deluxe (Demo available)
- Cogs (Demo available)
- Frozen Synapse (turn-based strategy) (Demo available)
- Osmos (Demo available)

Don't forget to search for videos etc..., because my definition for puzzle/logic and platform isn't always exactly the same as your definition of the genres.
