Sometimes the simplest of games for your Windows Phone can be the most enjoyable. Simple is a good way to describe This or That, a trivia game for you Windows Phone, because the answer is either this or that.

With This or That, you are presented a clue to a phrase that contains one of two single word choices. You compete in three, one minute rounds to answer ten questions. Correct answers increase your score and any time left earns you bonus points. This or That has over 1,700 phrases which gives the game plenty of playing time.

It sounds simple but I found the game rather challenging at times. This or That also has an addictive quality to it. You'll miss an obvious answer, say "DOH" and find yourself playing another round to prove you know these answers.

All in all, This or That is a fun, challenging, addictive game for your Windows Phone. There is a free trial version available that lets you play one, three round game. The full version runs $1.99 and you can download This or That here (opens Zune) at the Marketplace.
