Mario Kart World Announces ‘Summer Vacation Skill Test’ Event

Mario Kart World is running a Summer Vacation Skill Test event in-game later this month.

Announced on social media by Nintendo — and translated by OatmealDome — you’ll be able to participate in 150cc races with others to try and become one of the top 100 players in the world.

The event takes place on 23rd August 2025 between 8am to 10am UTC, but you can actually get practicing right now by using a neat little feature that’s tucked at the bottom of the Online screen.

You can now search for events by pressing the ‘-‘ button. The Summer Vacation Skill Test event can be found by typing in the ID 2378, and you can practice with people around the world right now.

After the event, the top 100 — and the best player for each character — will feature on the official Nintendo website.

Nintendo of America or Nintendo UK haven’t made a specific announcement yet, but the event ID above works for everyone.

Will you be taking part in this event later this month? Let us know in the comments.
