Developer Plain Vanilla Games is now taking sign-ups for beta testers to try out an early version of their popular trivia app QuizUp for Windows Phone. The company announced its plans to release QuizUp for both Windows Phone and Windows 8.1 in February.

Beta testers must agree to abide by a Non-Disclosure Agreement which, among other things, forbids them from posting any public screenshots or reviews of the QuizUp Windows Phone beta. From the language of the sign-up page, it looks like anyone who agrees to the NDA will be able to access the beta version.

QuizUp, which reportedly already has 32 million users worldwide, lets gamers play online trivia matches with friends and strangers. The actual development of the Windows Phone version is being handled by Gateway Apps. According to what we were told back in February, the Windows Phone version of QuizUp will have all of the features of the Android and iOS versions, plus Live tile support and possibly cross-platform play to the Android and IOS ports.
