Trivia Crack is Google's most downloaded trivia app. Now it's been developed and optimized for Android devices.

The goal of Trivia Crack is simple: Know the most trivia! You can face off against your friends or against any one of millions of potential opponents all over the world. There are six different categories, each category led by a new and exciting character. When you give Willy the Wheel a spin, fate will decide where your quiz questioning begins.

You can even create trivia questions of your own if your brain is overflowing with fun facts that you're dying to share. Trivia Crack's developers are also always looking for bilingual people to translate the content into more languages.

It's easy to play the game. Just follow a few steps:

1. Spin the wheel. It will land on one of six trivia categories. When you answer the question correctly, you'll get to spin again. If you answer incorrectly, your turn passes to your opponent.

2. Fill up your Crown gauge. You can collect characters when the wheel lands on the Crown section, or when you answer three questions in a row correctly.

3. Collect all six of the characters. You can win them by answering three consecutive questions correctly or by challenging your opponent to an exciting duel! You win the match when you've collected all the characters.
