In each league, there are 3 division (D3, D2, and D1), with D1 being the highest. Each season is a 5-game round robin tournament, with 6 teams total. The top 4 teams make it to the playoffs, where the semifinal games are seed-1 vs. seed-4 and seed-2 vs. seed-3. The winners of the semifinal play for the championship. During the 5-game round robin tournament, teams are ranked according to the following formula:
Team Points = 3 x nwins + 1 x nOTL + 0.1 x AGD
By these rankings, a win is worth 3 points, an overtime loss (OTL) is worth 1 point, and every goal in your aggregate goal differential (AGD) is worth 0.1 points. This also means that if your aggregate differential is negative, you can lose points from your team score.
