In the League contest all participants compete against each other in a round robin system.

The winner of each duel gets 3 points. In case of a draw, both players get 1 point.

When the League contest is over, the top ranked players will be promoted to a higher league, the bottom ranked players will be relegated to a lower league.

• In some prediction games (mostly football) the League contest will be staged twice.
• If the number of players exceeds the number of available rounds a player might compete against more than one opponent in a single round.
• If qualified players from the previous edition didn't sign in before the League contest starts, their places will be filled up by players from the next lower league.
• New players won't enter an already running League contest.

In prediction games with two League contests (first half and second half of the season), any matches from the first half that are postponed and not played before the start of the second half are excluded from the League contest.
This restriction is necessary to determine the promoted and relegated players before the start of the subsequent League contest.
