Pokémon GO Special Weekend

Pokémon GO Special Weekend was an recurring regional event in Pokémon GO.

July, 2018 Event
The event occurred in late July, 2018 throughout Japan and South Korea.

In order to participate, Trainers needed a special "Invitation Ticket", which could be exchanged by an official partner: 7-Eleven, Lotteria, or SK Telecom.

Trainers could scan the QR code in the "Invitation ticket" to check in at the official partner's pop-up PokéStop to participate in the event, although it was not possible to check in at a Gym. Check-in was possible from 10:00 am to 8:00 pm except for some areas. Check-ins at one location did not restrict travelers from moving between cities through out the day.

XP was doubled during this event.
