To play a ladder match, click the Multiplayer menu item in the top left, select a mode from 1v1, 2v2, 3v3, or 4v4, select a race, and then click Find Match. After playing in five placement matches within one mode (e.g. five 1v1 matches) you will be placed in a ladder for that mode. Note that Free For All (FFA) or arranged matches where you choose to play against specific friends do not count toward placement in a league, or ranking up or down within the ladder system.
