I have a new addiction--online puzzle games. I don't like jigsaw, or slide the tile, or get X# of gems in a row Connect Four type crap; I mean real mind bending puzzles that force you to think in three dimensions or more.
If you love great puzzles like me check these out on www. shockwave.com
And this one combines puzzle-like thinking with destruction (bonus!)
Metalix Tower Defense:
I've completed Hyper Frame and Bloxorz, and have gotten to level 20 on Metalix. Post a comment and let me know how far you get.
If Bloxorz drives you crazy, I've heard that there are solution videos on YouTube. But come on, the fun of puzzles is figuring them out without getting help.
