Thanks to MikeMirzayanov for the great systems Codeforces and Polygon.

Good luck and have fun to all finalists!

I suggest to us(the fans) to play the following game:

Rules of the game:

Choose your top 12 teams, this will be your prediction for the ICPC final. For each team you choose, you can get points. The conditions are as follows:

• if the team gets a medal, then you earn +2 points
• if the team gets the medal you predicted, then you earn +1 point. In your prediction, we will assume that the first 4 teams get gold medals, the next 4 teams get silver medals and the last 4 teams — bronze medals.
• if the team gets the predicted place, then you earn +2 point.

Thus, one team can bring up to 5 points.

The points of your prediction are the sum of the points of the 12 teams you have chosen.

If you want to participate in the game, you can submit your prediction here.

Also, you can check your prediction here. This is finished contest, where you can see checker log with abbreviations of your predicted universities.
