I like doing escape puzzles. Really they are a series of interconnected puzzles and you have to solve them to get out of a room. Sometimes you have to collect things along the way, but that does not seem to matter much. They tend to be visual puzzles and usually one part of the room has a hint to tell you what to do in another part of the room. Sometimes I get stuck and then later I will come back to it and then figure it out. A few times I gave up and resorted to a walk through.
