Gameloft will release downloadable versions of Mattel's card game UNO on PlayStation 3, PSP, Wii and Nintendo DSi later this year, the companies announced today. No Xbox 360 version, presumably because there's already an UNO game for Xbox Live Arcade.

No other details were mentioned, but come on, it's UNO. What else needs to be said? You try to get rid of all your cards before everyone else, either by matching the color or number of the last card played. When you're down to one card, you have to say "UNO."

Occasionally, someone will be a huge jerk and play a "Draw Four" wild card, widely regarded as the biggest dick move in the game, but hey, do you want to win or not?

Sales of downloadable Xbox Live Arcade games "almost tripled" in the week after the November 19th launch of the Xbox 360's new interface, Microsoft has announced.

In particular, Cabonated Games' UNO saw a 650% sales jump in just one day, a feat attributed to the fact that it was updated with support for the new customizable player avatars. NinjaBee's A Kingdom for Keflings, an avatar-utilizing game launched on November 19, "registered the second-best first week of performance ever."

In addition, Xbox Live members have added an average of 33% more friends since the New Xbox Experience hit, Xbox Live programming director Larry "Major Nelson" Hryb observed on his blog, though no explanation or hard numbers were given.
