I can't say I've ever played a stirring round of Rock Paper Skittles, but after reading about this contest, I'm definitely interested in giving it a shot.
Using advanced webcam recognition software on the rockpaperskittles.com website, users who buy specially marked packs of Skittles will be able to compete with other Skittles junkies worldwide by holding up a single Skittles candy to their webcam. The software will recognize what color Skittle the user is holding up, which is then matched up against a random opponent. A handy table on the website shows what colors beat which ones, and users can play Rock Paper Skittles up to 12 times a day.
If you're some sort of Rock Paper Skittles prodigy, then you could possibly win a $50,000 grand prize.
