Top division
Each round will be a round-robin tournament, where the teams play each other once within their group. The Preliminary Round is divided into two groups: Group A and Group B, which includes five teams each. From each group, the top three teams will qualify for the playoffs; the 1st-ranked teams earn a direct trip to the Semifinals, while the 2nd and 3rd-ranked teams qualify for the Quarterfinals. The 4th and 5th-ranked teams have to play in the Relegation Round, where the three best teams qualify for the Top Division tournament the following year, with the last-placed team being relegated to the Division I tournament the following year. In the Semifinals, the directly-qualified Semifinalists face the winners from the Quarterfinals.
