Which Mario Kart World mode eliminates racers at checkpoints?

Knockout Tour is the Mario Kart World mode that eliminates racers at checkpoints.

Instead of completing several separate laps on one circuit, players travel through a long rally across Mario Kart World’s interconnected courses. Racers must reach each checkpoint within the required placement range to remain in the event.

The mode supports up to 24 racers in its standard format. At the original checkpoint structure, four racers are eliminated at each of six intermediate checkpoints, steadily shrinking the field until the final competitors battle for the win. Later updates and formats can alter route details, but the checkpoint-elimination concept remains the mode’s defining feature.

This differs from Grand Prix, which scores results across separate races, and from Time Trials, which focus on individual speed. Balloon Battle is a combat-oriented battle mode rather than a checkpoint race, so none of those alternatives uses the same elimination system.
