Kayac's Hyper-Casual Games Achieve 1.5 Billion Downloads Worldwide

Kayac Hits Milestone of 1.5 Billion Downloads

Kayac Inc., headquartered in Kamakura, Kanagawa Prefecture, has announced that its portfolio of hyper-casual games has collectively surpassed 1.5 billion downloads worldwide as of August 14, 2025. This achievement comes just under 18 months after reaching the 1 billion download mark, marking the fastest acceleration with an additional 500 million downloads since then.

Key Factors Behind the Achievement

- Maturity of Advertising Operations: With unique operational know-how to maximize advertising revenues, Kayac has successfully propelled its business growth in proportion to download numbers.
- Dual Pillars of Long-Sellers and New Releases: The enduring success of titles like "Park Master," which hit 200 million downloads, contributes significantly to Kayac's stable income foundation.
- Diversity in Talent Fuels Creativity and Improvement Culture: Collaboration across departments and the integration of fresh ideas from new recruits have fostered a culture of collective improvement that drives hits.

Accelerating Growth with Strong Titles

Kayac launched its first hyper-casual game, "Park Master," in the U.S. on November 19, 2019. This genre is characterized by simple controls and quick gameplay, fundamentally supported by an advertising revenue model. Kayac maximizes its user acquisition and profitability through a unique data analytics framework, allowing users to enjoy games free of charge.

Before moving into full development, Kayac tests the market potential of games through advertising to ensure that only titles that meet stringent criteria such as LTV (Customer Lifetime Value) and CPI (Cost Per Install) advance to full production. Out of the titles in development, only about 5% that meet these criteria are released globally.

Despite the general trend of short-lived hyper-casual games, "Park Master" has achieved 200 million downloads within approximately 4 years and 10 months, serving as a stable revenue generator. In addition to existing long-sellers, the infusion of new ideas from employees with diverse backgrounds has led to 18 new titles launched in the last year and a half. Moreover, Kayac fosters a culture of collective input where all team members can contribute to game enhancement, resulting in unique hit games.

For instance, titles like "Kissing Now," developed by new graduates, and "Jetpack Master," have both reached 10 million downloads. Furthermore, the recently released "Grapple Hook Hero" achieved 2 million downloads within just one month of its launch, demonstrating the ongoing effectiveness of their new releases.
