Are you agile? Are you precise? How about balance? Can you balance things? Then I have a challenge for you....cup stacking, cyber style! You've probably stacked cups before or seen someone do it and you're thinking, "Man, that's easy!" Except it's not. At least not when you're using your mouse to move, drop and stack cups of different colors to get the pattern correct. Can you do it? You'll need a gentle, steady hand and a lot of patience to move through the levels. How many levels can you make it through? Get creative and have a super time with Cup Stacking!
