Mini Game is a service launched by Kakao Pay in February 2026, as the company aims to become a lifestyle financial platform. Users can enjoy a variety of games and perform simple missions to earn Kakao Pay Points as rewards. The games can be accessed directly on Kakao Pay and KakaoTalk without the need to install a separate game application.

Through the new agreement, Neptune plans to select from its popular intellectual property (IP) and affiliated casual games those best optimized for Kakao Pay users, and convert them into H5 (HTML5) format. In addition, the mobile advertising revenue maximization platform "AdX" will be integrated into games available on Kakao Pay. The goal is to enhance profitability by automatically serving advertisements with higher eCPM (effective cost per mille) through this structure.

Neptune is already collaborating with Toss as an "App in Toss" partner since July of last year. The company is successfully servicing about 30 games, including "Infinite Stairs" and "Cat Snack Bar," and has also hosted the "H5 Game Challenge" contest to prepare for supplying game content to platform operators.

Kwon Seunghyun, Head of Game Business Division at Neptune, stated, "Kakao Pay Mini Game is a platform where only select partners can supply games. This agreement is a recognition of Neptune's H5 game development capabilities and service operation expertise. Moving forward, we will continue to expand cooperation with major domestic platforms, broaden our game content supply foundation, and further strengthen our competitiveness in the H5 game business."
