QuizUp is my favorite game of all time. 

First of all I learn so many things! It has so many topics related to everything you can ever imagine! Think about one thing and go for it.

Another amazing thing, you play with people from the entire world! You can add them as friends if you want and also exchange messages!   

It has also the option to challenge and with every game you win points. At the 10th level you get a title that you can use and every title is related to the topic you're playing. The game has a 10 second setup for each question so your points will depend on the time you take to answer. 

There are so many amazing things about this game I can't even write them all!

The only downside is that you have to be connected to internet but let's be honest, nowadays we have internet everywhere so it's not that bit of a problem.
