Round 1 will be held starting on January 11, 2018 at 21:00 UTC and will finish on January 12, 2018 at 21:00 UTC. Only 1080 best strategies will be participating in it. The format of the games is 2x2. This stage will consist of 2 parts, and there will be a break between them (Sandbox will be available during it), that will allow participants to improve their strategies. Each part will last 12 hours, and a break — 24 hours.
In each part of Round 1 only last correct strategy, submitted before the corresponding part, will be used for the games. Games will appear in waves. In each wave each strategy will take part in exactly one game. Number of waves will be not less than 10.
Each game participants will be chosen randomly and equiprobably (in contrast to the Sandbox, where it is much more likely to meet an equal oppopent). The final results table of Round 1 will be formed by using sums of scores, gained throughout all the games, and 300 best strategies (in case of equal score, participant that submitted his strategy earlier is in priority) will pass to Round 2. The initial rating value of each participant is equal to 0, and each game he will be given a specified number of points:
