What the Mario Kart 8 Deluxe randomizer does

This Mario Kart 8 Deluxe randomizer builds a random four-part kart combo (character, vehicle, wheels and glider) for everyone at the table, then shuffles the tracks and items for your races. Whether you call it a Mario Kart 8 randomizer or an MK8DX randomizer, it handles up to 12 players, a tour-only track filter, drift and weight filters, and race counts up to 48. Open it in any browser, hit randomize, and play.
