Simple and addictive. Like crack, but not nearly as expensive.
Once I got Boom Blox home and loaded it up, I figured something out- ad campaigns don't always work.
Boom Blox is addictive and fun. It's use of the Wii Remote for pulling, pushing, and throwing make it hugely entertaining for everyone in the family. It's equal part Jenga drama, grenade toss destruction, and super ball spastics.
In single player mode, you get increasingly challenging puzzles that test your nerves and logic. Each time you successfully complete a puzzle, you unlock new pieces to use in the construction part of the game.
In the two player games, you can play both cooperatively and head-to-head. Some of the most fun I've had is playing the head-to-head tower tumbling levels against my family.
I learned that lesson the hard way. Boom Blox is a fun game to play for five minutes or for an entire rainy afternoon. Warning: A steady hand is necessary, so reduce your coffee consumption before playing.
