Rhythm Hive, a mobile rhythm game developed and serviced by Dreamage, is hosting an online and offline promotional event to celebrate the BOYNEXTDOOR TOUR KNOCK ON Vol.2 IN SEOUL. This promotion is being held in conjunction with the concert schedule at the KSPO Dome in Seoul, featuring exclusive in-game themes and on-site participatory programs.

During the concert period, a Rhythm Hive Play Zone will be set up at the venue. All visitors to the Play Zone will receive a coupon for a BOYNEXTDOOR performance card set that can be used in the game. Users who complete special in-game quests and verify them at the Play Zone will receive limited-edition physical photo cards on a first-come, first-served basis.

Additionally, an on-site verification event will be held for users who purchase in-game special theme packages. Users who purchase the packages and complete on-site verification will receive physical photo cards, and certain packages will include selfie photo cards as a special bonus. Package purchasers can also participate in a lucky draw event for a chance to win various prizes, including autographed albums and special lenticular photo cards.

Rhythm Hive has been conducting various online and offline events in line with the world tours of HYBE artists. Previously, the game provided unique experiences for users by linking in-game content with on-site events during TWS and LE SSERAFIM concerts. A Dreamage official stated, "Rhythm Hive is introducing various online and offline events so that fans can enjoy the artists' music in more diverse ways both inside and outside the game," adding, "We hope that through this promotion, users visiting the concert venue will create special memories by bridging the gap between the game and the concert."
