Playoffs are being played in four stages. Wild-card round is a best-of-3 series, with the quarter-finals, the semifinals and the final being best-of-7 series. The teams are reseeded after the first two stages, so that the best team by regular season performance to make the quarter-finals and the semifinals faces the worst team in the corresponding stage.
The bottom four teams will face the top two teams from Suomi-sarja in a double round-robin format. The four best placed get a place in Mestis for the next season.
