This summer belonged to Grow a Garden. For a few months, the cozy farming simulator dominated Roblox’s charts, capturing the attention of the entire Roblox community and breaking records along the way. But in September, the crown may be slipping.

99 Nights in the Forest, a survival game with horror elements that began gaining traction in June, has now surged past Grow a Garden in daily visits. From September 1–14, 99 Nights averaged 137M daily visits, compared to 108M for Grow a Garden. In total, that’s 1.5 billion visits in September so far, a 22% lead (data sourced from Rotrends). The game also benefits from longer average session lengths, meaning it isn’t just spamming visits like shorter-loop hits (looking at you, Steal a Brainrot). Add in higher average concurrent users during this period, and the picture becomes clearer.

The signal is clear: 99 Nights in the Forest isn’t just generating visits, it’s driving long-term engagement. It has surged past Grow a Garden in visits, while also maintaining higher average CCUs and longer play sessions than both Grow a Garden and Steal a Brainrot. That combination puts 99 Nights on pace to be Roblox’s most-played game of the month, marking a breakthrough moment, and potentially a changing of the tides. Let’s dive into what makes this game so special.

*By using a 14-day rolling average of Avg CCUs from Rotrends, we highlight sustained engagement trends while minimizing short-term noise from weekends or updates. This makes momentum shifts clearer and more meaningful.

Core Game Loop: Survival Built for Retention

At its heart, 99 Nights in the Forest is deceptively simple: survive 99 nights and rescue four missing children across the map. The structure splits into a clean day/night loop that players can grasp instantly but keeps returning to:

• Day: gather resources (logs, metals, etc.), craft survival tools (compass, sun dial, weapons, etc.), and fortify your base and campfire.

• Night: defend against escalating waves of enemies – deer, beasts, cultists, and more – and survive until dawn.

The structure works because it blends urgency with habit. The countdown mechanic, framed around 99 nights but extendable far beyond (top players reported at over 24,000 days), gives the game a sense of looming finality. Yet the day/night loop is compact and repeatable, creating that irresistible “just one more run effect.” 

The result is a game that’s both approachable for newcomers and sticky for veterans. Each session feels self-contained, yet the drive to survive one more night, and push progression just a little further, keeps players coming back, even after they beat the game and rescue the four children. It’s perfectly tuned for Roblox’s audience. 

Social Mechanics & Viral Appeal

99 Nights doesn’t just succeed because of its loop. Its real breakout power comes from how it plays socially and how it translates into shareable content.  

Fear x Humor Combo: The game can be played solo or in groups of five, but it clearly shines when played with friends. The cooperative chaos adds a social layer that amplifies both the tension and the comedy. It leans into Roblox’s unique horror space but never takes itself too seriously. The tension of surviving the night is constantly punctured by slapstick panic when groups of players scatter in chaos. This “scary but funny” balance makes it approachable for Roblox’s wide audience. We’ve seen this formula succeed outside Roblox in games like Minecraft’s Survival Mode and Lethal Company, and within Roblox in titles like Rainbow Friends.  

Viral Appeal: 99 Nights in the Forest, isn’t just fun to play, it’s also fun to watch. The game generates two distinct types of shareable moments: the chaotic jump scares that drive TikTok clips and YouTube Shorts, and the slower, more strategic satisfaction of watching players build bases and test their defenses. That survival layer adds an unexpected kind of watchability, content that feels closer to Minecraft than something you might see on Roblox. 

On YouTube, the results are striking. Its most popular base-building video, “I crafted the SAFEST BASE in 99 Nights in the Forest!” has already pulled in over 9 million views, and there are many other base-building videos pulling in millions of views.  It also has multiple YouTube shorts featuring chaotic survival moments, memes, and other relevant clips with over 50 million views. And the momentum isn’t limited to YouTube, on TikTok, its most popular video has already crossed 45 million views. For a game that only launched in June, that kind of traction highlights how quickly 99 Nights has broken through as both a playable and watchable phenomenon.

Classes, Badges, and Weekly Updates Drive Replayability

Where 99 Nights really shines is in how it layers progression on top of its simple loop, pulling in mechanics from both survival games and rogue-lites. Players aren’t just grinding night after night, they’re building, improving, and personalizing their experience over time. 

• Base-Building: Every run is a chance to refine and expand defenses, turning flimsy campfires on the first night into fortified strongholds. Watching those bases evolve is compelling, and it often motivates players to keep surviving well past the initial 99 nights

• Infinite Survival: While the premise is framed around surviving “99 nights”, there’s no actual limit. Players can keep surviving infinitely, transforming the game into an endurance night, fueling bragging rights and giving players a reason to keep pushing long after they’ve technically “beaten” the game.

• Creative Expression: Beyond pure utility, players have freedom in how they design their bases and what they craft. Just as Grow a Garden allows players to create unique gardens, 99 Nights taps into the same personalization loop. That sense of ownership makes progression feel more meaningful, players aren’t just surviving, they’re leaving their creative mark on the forest.

• Classes and Badges: Surviving 99 nights isn’t especially difficult, many players can do it in just a few hours. What drives replayability are the in-game badges (earned by completing specific objectives) and the wide variety of classes, each with unique strengths, abilities, and level-up paths. Together, these systems provide long term goals and incentives to keep returning. 

• Weekly Updates: Much like Grow a Garden, 99 Nights relies on weekly themed content drops to sustain momentum. New monsters, classes, badges, and locations are consistently added, ensuring players have fresh challenges and reasons to return. 

Together, these mechanics give players long-term reasons to replay, transforming what could have been a short-lived viral hit into a sustained engagement engine.

What’s Next for 99 Nights: Sustained Success or Viral Spike?

In just three months, 99 Nights in the Forest has scaled to a level few Roblox games have ever reached. It’s likely the first survival game on Roblox to sustain over 1M average concurrent users, placing its unique blend of survival and light horror alongside the platform’s dominant simulators and roleplay giants. By September’s end, it is on pace to finish as the most-played game of the month by average CCUs, overtaking Grow a Garden which has seen its numbers decline as it shifts away from weekly updates toward larger, long-term content drops.

That leap is no accident. The game’s sticky countdown loop, approachable blend of survival horror, and layered progression systems (badges, classes, base-building) create both the moment-to-moment tension and the long-term replayability needed to sustain interest. Weekly updates and infinite survival potential only add fuel to the fire.

And while much of the spotlight has been on Steal a Brainrot, which remarkably broke peak CCU records with nearly 24 million players across Roblox and Fortnite combined, it’s actually 99 Nights in the Forest that is maintaining users day after day, with higher average CCUs that reflect deeper retention and engagement.

For Roblox, it demonstrates that the platform isn’t limited to simple, viral-first games, deeper survival experiences can thrive at the very top. The real question now is whether 99 Nights in the Forest can sustain its momentum and grow into a lasting pillar like Brookhaven, or if it will follow the path of Dead Rails, a viral spike that briefly swept the community before fading into an afterthought.
