Veikkausliiga (; ) is the premier division of Finnish football, the highest tier of the Finnish football league structure, comprising the top 12 clubs of the country. Its main sponsor is the Finnish national betting agency Veikkaus, hence the league's name. Veikkausliiga was founded in 1990; before that the top division was called Mestaruussarja (championship series) since 1930 which was an amateur or semi-professional league. Between 1908 and 1930 the championship was decided as a knock-out cup competition. Structure During the 1990 and 1991 seasons the Veikkausliiga was played under the name "Futisliiga" (). As with certain other cold-climate European countries, league matches in Finland are played in summer, with a schedule usually from April to October. The format and number of teams has changed frequently. As of 2020 there are 12 teams, which first face the other teams two times. After the two rounds, the league is divided into championship group (6 teams) and challenge group (6 teams), and both groups play a single series of five further matches. At the end of the season, the last team is relegated to Ykkönen, whose winner is promoted to Veikkausliiga, and the second last team plays a two-leg play-off versus the Ykkönen runner-up. In 2010 the average annual salary with fringe benefits for a league player was 24,400 euros. Veikkausliiga is a founding member of the European Professional Football Leagues association.
