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.
