Devsisters said on Thursday its mobile idle role-playing game \"CookieRun: Crumble\" has topped 20 billion won in cumulative sales a month after launch. The game, developed by Studio Kingdom, launched globally on July 30 and has more than 2.5 million cumulative users. Devsisters said many users have not played prior CookieRun titles. Apple App Store users rate the game 4.7 out of 5.

South Korean game companies are accelerating efforts to build in-house payment systems that sell directly to users without going through app markets. The goal is to cut platform fees and improve profitability while securing payment data and direct user touchpoints. Krafton completed a strategic investment in Neon Commerce, which supports web stores, payments and tax and regulatory compliance. Major publishers are widening off-app payment routes, but success depends on whether users actually switch to them.
