Neptune Co., Ltd. (CEO Kang Yul-bin) announced that a total of 10 of its H5 games, including its flagship casual mobile game Infinite Stairs, have launched on South Korea's largest messaging platform, KakaoTalk.

Marking its 11th year since launch, Neptune's long-standing IP Infinite Stairs features simple tap controls to climb stairs and intuitive gameplay. Since its early days of service, it has maintained widespread popularity across all age groups, including elementary school students.

Leveraging the high brand recognition of Infinite Stairs, Neptune partnered with KakaoTalk to introduce the title as an H5 game on KakaoTalk's in-app gameplay service, allowing users to enjoy Infinite Stairs directly within KakaoTalk without the hassle of installing a separate app.

In addition, considering the preferences of KakaoTalk users, Neptune plans to curate a lineup of casual mobile games it owns or publishes, convert them into H5 games, and add them to the platform. Currently, Infinite Stairs reached No. 1 in popularity rankings just one week after launch, while three other titles—Infinite Shooting, Infinite Farm, and Infinite Ranch—have settled within the top 10.

Building on its track record of supplying H5 games to platforms ranging from financial platform Toss to YouTube, TikTok, and CrazyGames prior to KakaoTalk, Neptune plans to focus on securing H5 game distribution channels to drive new user acquisition.

Kwon Seung-hyun, Head of Neptune's Game Business Division, said, "We expect synergy to be maximized as KakaoTalk, Korea's representative messenger, meets Infinite Stairs, a nationwide favorite game. Leveraging KakaoTalk's massive traffic and accessibility, we will expand the user base for Infinite Stairs."
