GameShuffle's tournament builder runs real Mario Kart 8 Deluxe and Mario Kart World competitions. Pick a one-off tournament in any format (brackets, round-robin, FFA points, or the Heat → Mains ladder) or a season-long championship series, then run it live with real-time standings on a public page, your OBS overlay, and Twitch chat. And because GameShuffle owns the randomizers, you can run randomized rounds where everyone races the same shuffled tracks, combo, or items, held to your build rules and revealed live, something a generic bracket tool can't do. Free to create with an account.
What you can do
Randomized rounds (GameShuffle exclusive)
Everyone runs the same randomized tracks, shared kart combo, and/or item set each round, generated by our own randomizers and held to your build rules. Reveal each round live, or a fresh combo every race.
Championship series
Run a season of events. Points carry across nights into a live league standings table, with drop-worst support.
Heat → Mains ladder
Sprint-car-style: race heats into A/B mains, win to lock the A Main, and top finishers transfer up. A way back from a bad start.
Single & double-elim brackets
Auto-seeded brackets with byes, winners/losers rounds, and a live public bracket.
Live scoring & standings
Enter each race's finish for real-time cumulative standings, then finalize the podium.
Now racing: live everywhere
Advance the current race and it updates the public tournament page in real time, plus your OBS overlay and Twitch chat when you stream (or drive it with !gs-tourney).
Reminders & change alerts
Players get 1-day and 1-hour reminders, and an instant email + notification if you reschedule or cancel, with start times in their own timezone.
Track & build rules
Guided, FFA, randomized, or limited tracks plus weight, drift/vehicle, and character limits.
Guests & seeding
Add players without an account and seed by check-in, standings, or random, for MK8DX and Mario Kart World.
