I knew it was rigged!
WOW, after seeing this I now believe I saw something happen! I was able to get the damn thing to the LAST tier before WINNING like 4 times with 20 bucks and could NEVER do it! It was cool I got so good that I could just pop them in on the first wave but then I got to the top and was scurred. What a scam. I really wanted that ipod touch too
