Every kart has 4 hearts. Knock the others out to score; the KO goes to whoever takes the last heart. Rounds last a few minutes; most KOs wins.
Drive into ? boxes for an item: a rocket (1 heart), a bomb (up to 2 hearts), a mine (1½ hearts) or a boost (ram someone while boosting for ½ heart).
Hold drift while steering at speed: the sparks turn gold, then pink; let go for a mini-turbo.
