[Digital Today reporter Ho-jung Lee] Devsisters will hold an offline event, the Cookie Run Grand Festival, at Seoul Children's Grand Park on Oct. 24-25, bringing together its Cookie Run intellectual property (IP).

Devsisters on Tuesday unveiled the detailed programme. The event will feature the Cookie Run: OvenBreak World Championship 2026 finals, the first Cookie Run marathon, an OvenBreak 10th anniversary exhibition and hands-on programmes, and an augmented reality (AR) tour.

The World Championship finals will be held on both days at the park's Forest Stage. The quarter-finals will be held on the first day, with the semi-finals and final on the second day. Matches will also be streamed live on the official Cookie Run: OvenBreak YouTube channel.

The stage will also host Challenge! Cookie Golden Bell, World Championship match prediction and a 10th anniversary special stage. The World Championship seating will be split into 500 reserved seats and general admission. Reserved seats will be sold for a fee.

On the morning of Oct. 25, the first marathon using the Cookie Run IP, Brave CookieRUN in Seoul, will be held. It will offer 5 km and 10 km courses, and finishers will receive a "Brave Medal". Participation tickets will be sold on the running platform Runnerble through Oct. 12.

The marathon will also feature photo zones, sponsor booths, a cosplay awards ceremony and a prize draw event.

Exhibition and hands-on content marking the 10th anniversary of the release of Cookie Run: OvenBreak will also be offered. Planned attractions include a "Memories Title Road" featuring illustrations from past titles, a hands-on zone previewing the 10th anniversary update, a record competition space, and fan message and photo areas.

An AR tour will also take place throughout the park. Participants will scan images installed on site to collect about 100 types of cookies and complete missions such as quizzes or scanning cookie statues. Those who complete missions can receive a random photo card featuring cookie illustrations.

The event offers free entry on site and has no separate age limit. Some programmes, including World Championship reserved seating and the marathon, will be run for a fee or via separate registration.
