Hi all!

I invite you to take part in Codeforces Marathon Round 2. The contest will start on Tuesday, July 24, 2018 at 15:00 MSK, and will last for 7 days. There will be one problem based on game mechanics of a couple of board games for children. The problem most likely does not have a fast and full solution. So the solutions will be given scores, and the winner will be the one who gets the highest total score.

The contest will be unrated because the problem is considerably different from the problems of rated rounds.

During the time of the contest, the solutions will be checked on examples and preliminary tests. After the contest is over, the final solution of each contestant will be checked on the final test set, and the total score for this test set will determine the final scoreboard. The contest will take place on Codeforces platform and is supported by the Community Of Master Programming at St. Petersburg State University (link in Russian) and 90.01 Group.

The Codeforces platform has seen only few marathons so far. So, if something breaks, don't be upset, just write about it, and we will try to fix it.

Good luck in the contest!
