What do you need to participate?
- A Nintendo Switch 2 system
- Mario Kart World
- A Nintendo Account
- An internet connection
- A Nintendo Switch Online membership for online features; membership is sold separately
Nintendo’s announcement mentions a free seven-day Nintendo Switch Online trial, but it is not a condition-free or universally available offer: Nintendo says the trial converts to a one-month auto-renewing membership at the then-current price unless canceled, and that country limits and other restrictions apply. Check the membership offer shown for your account and region before starting a trial.

How is the October Open related to the December Fall Cup?
Nintendo describes the October Open as a qualifier for the Mario Kart World Fall Cup 2026, planned for December. The announcement says the Fall Cup itself is exclusive to North American players. This is separate from the Open’s reward wording, which covers eligible participants from North and South American regions; do not assume that receiving the Open participation reward makes a player eligible for the Fall Cup.

The announcement’s Fall Cup rules summary describes a separate promotion, including a September 19–approximately December 12 tournament period and a top-24 placement in one qualifying event as the championship qualification threshold. It also summarizes age, residency, system, game, account, internet, and membership requirements. These summary terms do not replace the promotion’s official rules, which Nintendo links from its announcement. Consult those rules for complete eligibility and entry terms.
