All rules are the same for tournaments, unless otherwise specifically noted. For example, pitching limits are the same for tournaments as the current season. But, teams with more players can match the # of batters of the team with less (required to sub the remaining players not on the initial batting lineup) - see rule 4.a.i. https://www.neobaseball.org/rules
Tournaments are single elimination and the higher seed is home team unless specifically noted otherwise.
We do allow for teams to play a full (6 or 7 inning) game or do an extended time limit for the Championship games only (NOTE: If both teams don't agree to adjusting/removing the time limit, then it will remain in place).
