Ultraliga is the domestic league that qualifies polish national teams to the European Masters. The regular season is played online and features eight teams and it's split into two stages. With the first one being a round robin with all of the eight teams.

For the second stage the teams are divided into the Master Stage and Relegation Stage with the top four in the masters and the bottom four in the relegation stage. While the bottom stage is called relegation stage, the top two of the four teams will still be playing in the playoffs but the top two teams in the Master Stage will be seeded into the semifinals in the playoffs, a luxury the relegation stage teams cannot achieve.
