Case closed: Detective Conan puzzle pop-up in Hongdae needs a reservation

If you're a Detective Conan fan heading to Seoul, this pop-up in Hongdae is exactly the kind of immersive experience that justifies the trip. The pop-up is a live puzzle-solving game — not a merchandise-only photo zone — built around a wedding-mystery storyline called "Halloween's Wedding Mystery." You're placed on a team of six (strangers included) and work together to crack clues and solve the case in real time. The blogger who visited called it genuinely engaging, even for first-timers at escape-game-style puzzles, and praised the collaborative energy of working through hints with teammates you've just met.

The location is near Seonggyeong Elementary School in Hongdae, very walkable from Hongik University Station. The blogger strongly recommends taking the subway — parking at Hongik University lot costs 18,000 won for 8 hours on weekends, which is steep. The entrance is basement level (B1), marked with pamphlets and arrows as you approach. Walk-ins are not allowed; you must book in advance via Naver Reservations. Both the standard ticket and the special ticket cost 35,000 won each. The difference: the special ticket includes extra "fun elements" woven into the game experience (the blogger couldn't detail specifics without spoiling the mystery). Arrive 30 minutes before your reservation time to check in smoothly. The wait is usually minimal, but that buffer keeps things running on schedule.

One practical detail: if you're going with a group, book all tickets under the same Naver account to guarantee you're on the same team. Seating is assigned, and changing it on-site requires staff approval. The blogger and their group successfully solved the mystery with teamwork and the hint booklet provided — so difficulty is manageable if you collaborate. The immersive wedding-venue set design adds to the atmosphere. This is an active, social experience, not a passive photo op, so it's best for visitors comfortable with talking through puzzles with strangers.

The blogger's final tips: use public transit, coordinate your group's booking beforehand, and consider the special ticket if you want a slightly richer puzzle experience. If you arrive early in Hongdae, they also recommend grabbing Chicago-style pizza nearby before heading to the pop-up. Check the Naver Reservations page for the current running window and book your slot — this is not a walk-up venue.
