I found this a while ago and it was pretty fun and addictive. I've been told it can be beaten, that there are not an infinite number of levels. I only played it three times, though, with 320 being my high score.

240 and counting. Those little cups get devious!

120 on my first try. Boy, I suck. ^_~

LOL, no way. I said my third and final try was a 320, but my first score was a 60, ha. It went 60 to 290 to 320.
