Logic puzzles like making potions , traping a mouse, distract someone's attention, those kind especially.
Other puzzles I like:
Longest Journey- the turning stones with symbols from the 5 scenes;
(Other symbols puzzle -in Chronicles of mystery, Keepsake, etc)
Broken Sword 3 - Pushing the crates in Congo in the caves to balance the piece of stone.
(It's odd, because most people find those crate pushing anoying
