Play Mode

 * Free mode- In free mode the player can freely choose CPU opponents to play against.
 * Challenge mode- Win by fulfilling a given set of conditions with a given set of opponents. Easy, normal, and hard challenges are available, with Wario and Waluigi being unlocked after completing all the Easy challenges.
 * Ranking mode- The character chosen starts at rank 20. He/she plays against the other characters to ascend and possibly become rank 1 (top 3 opponents are Petey Piranha, Bowser, and Toadsworth in ascending order). Note that the ranking system works by winning points from beating other players; thus, the top opponents do not need to be unlocked in order to ascend above them.
 * Local multiplayer- A game for multiple players (up to 4), all within range of the DS wireless radio.
 * Online multiplayer- Like online multiplayer for other DS games, with the same Friend Code system. Voice chat is available.
