Roblox Top Games of September
Plants vs. Brainrots Rises Fast
According to the latest analysis, Plants vs. Brainrots saw explosive growth during September, doubling its daily player count for two weeks straight. That kind of momentum is rare, even by Roblox standards. The game averaged around 916,000 concurrent users last week, ranking it as the third most played experience on the platform - just behind 99 Nights in the Forest and Steal a Brainrot. This rapid climb marks one of the fastest ascents seen since Grow a Garden first went viral earlier in the year.
Fish It! Finds Its Moment
Another major story this month is the quiet but steady rise of Fish It!. The fishing sim jumped 18 places in time spent, landing at #7 overall. Many players appear to have shifted over from Grow a Garden, which dominated casual play earlier this year. The original Fisch - the game that kicked off Roblox’s fishing craze - also made a surprise return, climbing back into the Top 15 earners after dropping out of the Top 100 just months ago. The comeback suggests that players are still drawn to slower, social experiences amid the platform’s fast-paced trends.
Steady Leaders Hold the Line
Despite new contenders, long-standing titles 99 Nights in the Forest and Steal a Brainrot continue to hold their ground. Both remain among the most-played and highest-earning games on Roblox, with tens of millions of users each month. The report notes that these games tend to hold player interest for months at a time, but once migration begins, it can happen quickly - opening space for newer releases to climb into the top spots.
Roblox’s Player Base Keeps Expanding
The report also highlights Roblox’s broader success in maintaining a massive active player base. The platform regularly reaches between 10 and 20 million concurrent users, with a recent peak of over 42 million. That scale continues to make Roblox one of the largest ecosystems in gaming, with insights offering rare glimpses into player behavior across genres ranging from social sims to action-based adventures.
