It will be the only bracket game you'll play ahead of that big tournament in Brazil. And if you run an office pool, it will be your best friend.

The Brazil Bracket Challenge presented by CapriSun is free and easy to play. Pick your top two finishers in each group and complete the rest of the bracket. Then share it with your friends, tweet it out or print it and flaunt it. And you have until 2 pm ET on June 12 -- the day of the inaugural match between hosts Brazil and Croatia -- to make tweaks before the bracket locks.

There are no official prizes, but if you finish tops in the nation or even in your own league, it'd sure be pretty cool to be known as an international soccer expert. Here's how you play:
