The big 'ol quiz game that is QuizUp has just been updated. Now iPad users can finally get in on the fun as the game has gone universal and been optimized for Apple's tablets. Plain Vanilla Games see it becoming more of a "social trivia network" than simply a game, and as such they're determined to focus on the social elements - hence making the game universal, and tweaking the leaderboard to emphasize social relationships and interaction.
So if you've got an iPad and you'd like to join the now 10 million-plus users already getting their trivia on with 190,000 different questions, why not give it a download? It is free, after all.
