DreamAge announced on the 1st that it has applied a new update to its mobile puzzle game Puzzle Seventeen, which it develops and services, and has revealed new content and events. This update adds a new island, 'Thunder Island,' themed around the idol group Seventeen's song 'THUNDER.' Additionally, a new content called 'Sebong Jjakjjakkung,' designed with a concert hall concept, has also been introduced.

The new content, 'Sebong Jjakjjakkung,' is an event played by flipping cards to match pairs, and participation is possible using event currency obtained by successfully completing puzzles. Participants will be offered a variety of rewards. In addition, a new special box linked to Seventeen's best album '17 IS RIGHT HERE' has also been opened. This special box offers representative outfits from Seventeen's Hip-Hop Unit, Performance Unit, and Vocal Unit, reborn as costumes within Puzzle Seventeen.

Various events are also prepared in anticipation of the return of artist Seventeen's member Jeonghan. A '1004 Deco Collection Event' and a quest event providing special deco rewards are underway. Furthermore, an authentication event to commemorate the birthdays of members Jun, Hoshi, and Wonwoo is being conducted through the official SNS. Their birthday costumes can also be found within the game.

This update and event are imbued with the meaning of commemorating Seventeen's content and members' activities, which were greatly loved by the fandom CARAT, within the Puzzle Seventeen game.
