The teams that finish 7th through 10th play a play-in series (best-of-five) to determine who will join the top six into the playoff quarter-finals (best-of-seven). No final is played. Instead, two teams which win the semifinals are declared co-champions and both advance to the qualifying group against two worst placed teams at the end of the Extraliga regular season.

The four lowest ranked teams (11–14) after the regular season play in a play-out group (12 games, all regular-season matches are counted into the ranking). The worst team after 12 rounds is relegated to the Czech 2. Liga.
