The play for two teams, in which is necessary to draw two fields adjacent to each other, with tunnels forking from each other. There are bases in the corners of each field and semicircular "safety zones" at the ends of the tunnels. The players' task is capturing the opponent's base. The participants move in the direction of the base so as not to be captured by the opponent on his/her side. The captured person is eliminated from the play. If he/she is in a "safety zone", then he/she cannot be captured by the opponent. The winner is the team which was the first to capture the opponent's base.
