Oh crap I'm 7 again, and I've lost my life!
The game is fun, it's simple and to the point, but the amount of startegy and hand to eye cordination for this game is suprisngly astoudning. You're goal is to match 4 beans of the same color. When this happens you'll send some rocks over to your opponet which will then drop down disrupting play. He can do this too, so just watch out. However this isnt' enough, you must map out your plan of attack to allow combos to go off, so when one group of four pops away another group of four is fromed from beans around it. This takes some complex planning, quick thinking, and occasionally dumb luck. There are numerosu levels, and the difference between the first level and the last level is astoudning. The AI becomes steadly better as you progress, and you'll find yourself addictied in no time.
For seven bucks it might be a little expensive, as if you have a gensis laying around you can probalby find this game on ebay for a fairly cheap price. Though SandH may make the Wii version a lot more attaractive.
I say buy it if you're looking for one of the best puzzle games of all time, even if you've never heard of it, and the title tells you otherwise.
