Where are some good simple puzzle games?

• I'm looking for some good, simple puzzle games. Online or iPhone. I recently discovered the joys of playing simple-but-challenging puzzle games while watching TV, waiting in line, etc. But I've exhausted all the levels on my recent favorites, so I need some new ones. For some reason I seem to really enjoy games with blocks that need to be either moved around or stacked in some way, yet http://www.metafilter.com/33865/Slip-sliding-away-insane-brain-games don't seem to do it for me. Some games I've enjoyed recently: http://www.kongregate.com/games/Chandler/jelly-blocks http://www.albinoblacksheep.com/games/bloxorz http://www.finestfreeonlinegames.com/play-21258-Gridlock.html There was also a cute little stacking game recommended on the blue, but I can't seem to find it. My aptitude for these games puts me at about a fifth grade level, so feel free to suggest your ten-year-old's favorite game. Online and iPhone games are both welcome. Oh, and I'd like to avoid games that have lots of time pressures, since I play these while doing other things.

• Answer:

  http://fantasticcontraption.com/ is one of the best puzzle games I've ever played. That link goes to the on-line version but there is an iPhone version available from the app store. I don't remember what it cost but it was cheap enough that I felt like I really got my money's worth. It starts out simple, then it becomes hard, then it starts to look impossible but if you keep at it you realize it can be done. Then the last two levels are so tough you give up on it and feel like you got cheated. But before those last two levels there are 40 others that are a lot of fun. Overall it might be harder than you're looking for, but the puzzles can left as-is and you can come back to finish them later. You can also skip around, you don't need to solve one before moving on to the next one.
