Best Mobile Game Genres of 2018: Top Free Games Charts

The mobile gaming landscape in 2018 was defined by significant shifts in genre dominance and market saturation. The primary objective of this analysis is to evaluate the performance of various mobile game genres within the US market by examining the top 500 free-to-play titles across each quarter of 2018. By categorizing these games into 40 distinct sub-genres based on specific mechanics rather than broad store classifications, the research identifies which genres offer the most potential for growth and which are currently oversaturated.

Hypercasual games emerged as the dominant force in the download charts throughout 2018, consistently maintaining the highest volume of titles. While hypercasual mechanics—often driven by ad-revenue models—remained the most reliable for securing high download rankings, the data indicates a slight decline in their total volume toward the end of the year. Conversely, genres such as Battle Royale and Augmented Reality (AR) functioned as rising stars, characterized by a smaller number of high-performing titles that maintained strong, consistent chart positions. Other categories, including Puzzle, Word, and Arcade, demonstrated stability and steady growth, serving as safer, more reliable options for developers compared to the volatile hypercasual market.

Methodologically, the analysis utilizes a dataset of the top 500 downloaded apps in the US, applying metrics such as mean, median, and standard deviation to assess genre performance. The findings suggest that while hypercasual games currently lead in sheer volume, there is a clear opportunity for developers to innovate by applying simple, accessible mechanics to more niche or historically underserved genres. Ultimately, the research concludes that achieving top-tier download performance requires balancing broad appeal with effective, modern monetization strategies, while cautioning that male-targeted genres like MOBA and RPG continue to face significant challenges in achieving high download ranks.
