Poker, word games, bingo, classic abstracts, UNO, and dice. Looks like there’s plenty of room for some more innovation and not a lot of competition here, folks.

unoUNO is steadily gaining in popularity on Facebook, and now has over 60,000 registered players.

It’s still in Beta, and has a few problems with crashing and slowness. And it’s really not that interesting a game, compared to Scrabble, but I don’t make the stats.

Expect a boost if/when the game gets integrated with all the other platforms that support UNO, such as mobile phones and ipods.
