Round 2 will start on December 20, 2019 at 21:00 UTC and finish on December 21, 2019 at 21:00 UTC. Best 300 strategies from Round 1 and additional 60 strategies from the Sandbox will take part in it. Format of the games will be 2x2. This stage, same as previous, will consist of 2 parts 12 hours each, and a break in between 24 hours long, so that participants can improve their strategies. Games in each part will use latest correct strategy, submitted before the beginning of the corresponding part. Games will be held, like before, in waves. Each wave each strategy will take part in exactly one game. In the end rating will be calculated, similarly to Round 1, and 50 best strategies (in case of equal rating participant who submitted his strategy earlier has priority) will pass to the Finals to find out the best one.
