A free app for Android, by creatorandapps.
The app is divided into 10 levels, with each level harder than the previous one. The goal of each level is to earn as many points as possible.
To get points, you have to answer all the multiple-choice questions correctly. Each wrong answer will cost you time, and your chance to unlock the next level.
If you're feeling confident, you can play against your friends in the new multiplayer mode. Just create a game, and share it with any of your friends to join you.
If your friends don't have the game, they will be taken straight to the download page.
