League Mode is a round-robin tournament mode that lets you compete head-to-head with 2-6 people or CPU equivalents. If you are with your friends and you don't feel like playing each and every one of them, press the minus button on the Wii Remote and it will take you to Playoff Mode. Playoff Mode is like a postseason where you choose the teams, except for that there's only 6 people and you play a one-game series.
