Ditto Playground entry in Seongsu is being handled through an on-site QR-code waiting system, not a simple walk-in line. The official guidance says the space runs from May 1 to June 21, 2026, at 9 Seongsui-ro 7ga-gil, Seongsu-dong, Seongdong-gu, Seoul, with basic admission available free of charge.1
The key point for visitors is that entry depends on registration and crowd conditions. Visitors register for the waiting list by QR code, then enter when they receive an AlimTalk or text-message call; the official FAQ also warns that waiting or entry restrictions may occur depending on the situation on site.1
How Ditto Playground Entry Works

The practical entry flow is straightforward but important to follow carefully. First, go to the Seongsu-dong venue area and use the QR code provided on site to register for the waiting list. After registration, do not assume immediate entry. The next step is to wait until a call notice arrives through AlimTalk or text message, because that notification is the signal used for admission.1
Because admission is free at the basic level, the main constraint is not a listed ticket price but capacity control. The official guidance does not provide a fixed hourly admission count, a guaranteed wait time, or a separate advance-booking channel in the source material. That means visitors should plan around uncertainty: the waiting list may move differently depending on the day, and the venue can limit entry when the area becomes too crowded.1
Ditto Playground is part of Pokemon Mega Festa 2026, a broader 30th-anniversary program held across Seoul in May and beyond. Reported programs include Pokemon Secret Forest, Ditto Playground, Pokemon 30th Anniversary Party, Pokemon Run 2026, and Pokemon Sports Day 2026.2 For the Seongsu location specifically, coverage described Ditto Playground as a purple Ditto-themed space in the Seongsu-dong area, with original goods also introduced as part of the program.2
Crowd Controls After the May 1 Opening
The entry process matters even more because the opening day brought serious crowd-management issues. On May 1, 2026, large crowds gathered around Seongsu-dong and Seoul Forest for Pokemon Mega Festa 2026, and some programs, including Ditto Playground entry, were halted. Financial News, carrying a Newsis report, said the event was stopped around 11 a.m., police deployed about 90 personnel at the request of local authorities, and dispersal at the site was understood to have finished around 2:15 p.m.3
Segye Ilbo reported that police and fire authorities responded after multiple safety-concern reports were received. It also cited Seoul city estimates that the crowd around Seongsu Cafe Street rose from 26,000 people at 10 a.m. to about 40,000 around noon, and reported that no injuries occurred.4
Pokemon Korea’s social notice, quoted in the reports, said the event was temporarily suspended “for safety reasons due to large crowds.”4 Another quoted notice said that “collisions are occurring due to large crowds,” which explains why the opening-day entry situation changed quickly and why the official warning about possible entry limits should be treated as practical guidance, not a formality.3
As of the May 4 reporting in the supplied material, the stamp rally had been urgently suspended after opening-day crowding, but exhibition spaces and the Pokemon 30th Anniversary Party pop-up were reported to be continuing as scheduled with strengthened safety management.5 The same report said the stamp rally had been planned around six designated PokeStops, including Seongsu-dong Shoe Theme Park, Rainbow Children’s Park, and Ditto Playground.5
What to Check Before Going
For a visit focused on Ditto Playground, the safest reading of the available facts is this: the official operating period and free basic admission remain central, but actual entry is controlled on site through QR waiting and may be restricted. The source material does not include a guaranteed same-day entry promise, a refund policy, detailed merchandise purchase rules, or a revised post-disruption capacity schedule.
Visitors should therefore treat the QR registration and call notification as mandatory steps. If the site is crowded, arriving at the area does not necessarily mean entry will be available. The official FAQ already allows for waiting or entry limits, and opening-day reports show that those limits can be applied when safety conditions require them.1

Quick FAQ
Is Ditto Playground free to enter?
Basic admission is free, based on the official FAQ. Entry still requires QR-code waiting registration and admission after an AlimTalk or text-message call, with possible restrictions depending on on-site conditions.1
Where and when is Ditto Playground operating?
The official listing gives the operating period as May 1 to June 21, 2026, and the location as 9 Seongsui-ro 7ga-gil, Seongsu-dong, Seongdong-gu, Seoul.1 In short, Ditto Playground is not just a place to show up and enter immediately. The available guidance points to a free but controlled admission system built around QR waiting, mobile call notices, and safety-based entry limits, so visitors should plan around the official process and the possibility of on-site restrictions.
