Kayac's Hyper-Casual Games Surpass 1.5 Billion Downloads. | KAYAC

~ Adds 500 Million in Record Time After Hitting 1 Billion Milestone Driven by Both Long-Sellers and New Titles ~

Kayac Inc. (Head Office: Kamakura City, Kanagawa Prefecture, CEO: Daisuke Yanagisawa; hereinafter referred to as “Kayac Inc.”) is pleased to announce that the total downloads of their 46 hyper-casual game titles produced and distributed by the company have reached 1.5 billion worldwide as of August 14, 2025. This milestone was achieved in less than a year and a half since reaching 1 billion total downloads, marking the fastest-ever additional 500 million downloads.

Key Points Behind the 1.5 Billion Download Milestone

● Matured advertising operations expertise: By leveraging unique methodology in development and ad operations to maximize ad revenue, the company has achieved business growth proportional to the number of downloads.

● Two pillars of long-sellers and new titles: Multiple long-selling titles, such as “Park Master,” which alone surpassed 200 million downloads in about five years since launch, provide a stable revenue base.

● Planning power and improvement culture from diverse talent: Fresh ideas from new graduates and transfers from other departments, combined with a culture of continuous team-wide improvement (“all-hands participation”), drive hit creation.

Growth Fueled by the Twin Engines of Established Hits and New Releases

Kayac Inc. launched their first hyper-casual game, Park Master, in the U.S. on November 19, 2019. Hyper-casual games are smartphone games that are easy to play with simple controls and can be enjoyed in short bursts. Using an ad-based revenue model, the company utilizes a proprietary data analysis platform to optimize user acquisition and profitability, enabling players to enjoy the games completely free of charge.
Before entering full development, the potential of each game is tested via prototype ad campaigns, and only those titles that meet strict criteria such as LTV (Lifetime Value) and CPI (Cost Per Install) proceed to full development. At Kayac Inc., only about 5% of prototyped titles pass these standards and are released worldwide.
While many hyper-casual games are short-lived, Park Master, the company’s very first title, has proven to be an enduring hit, reaching 200 million downloads in under five years after release, and continues to serve as a stable revenue source.
long-selling titles like Park Master, 18 new titles have been launched in the past year and a half, fueled by fresh ideas from diverse talent such as internal transfers and new graduates. The hyper-casual team embraces a culture where all members, regardless of role or experience, continuously improve the games together. This open and collaborative environment has given rise to unique hits.
The success of these new titles is exemplified by several recent hits:
● Kissing Now, developed by an employee who joined as a new graduate in 2024, has surpassed 10 million downloads.
● Jetpack Master has also achieved the 10-million-download milestone.
● Grapple Hook Hero, released just last month, garnered 2 million downloads in its first month.
Collectively, the strong performance of these new titles was a key driver in pushing the company past the 1.5 billion total download milestone.
