Caso o torneio tenha mais de 15 jogadores, irei sortear também uma partida orientada. Se o torneio tiver mais de 25 jogadores irei sortear também uma aula particular(1h-1h30m de duração) com o tema a escolha do sorteado.\n\nPara concorrer ao sorteio basta ao jogador jogar o torneio, para cada partida que o jogador jogar no torneio(incluindo vitórias por ausência e bye) ele terá uma chance no torneio. Aqueles que forem padrinhos do meu projeto(https://www.padrim.com.br/aulasdegofhvr) e terminarem o torneio terão duas vezes essas chances.",
