Devsisters' mobile idle RPG 'Cookie Run: Crumble' has surpassed 20 billion won in cumulative revenue less than a month after its global launch. Cumulative players have passed 2.5 million.

According to official figures announced by Devsisters on August 27, 'Cookie Run: Crumble' achieved this milestone less than a month after its release on July 30. These figures are based on internal company tracking rather than estimates from external market research firms.

Overseas revenue accounted for 40% of the total. Outside of South Korea, the United States was the highest-grossing market.

'Cookie Run: Crumble' is a mobile idle RPG developed by StudioKingdom, a studio under Devsisters. It combines an idle structure where characters grow automatically with elements of collecting and combining Cookies and Pets.

Meanwhile, Devsisters released the first major update for 'Cookie Run: Crumble' on August 27. The update added 'Guild Battle'—a mode where rankings are determined by combining guild members' boss fight scores—along with new Cookies, Pets, and other content.
