Why Are People Spending 30+ Minutes in This Bubble Popping Simulator?
Bubble Gum Simulator INFINITY, the sequel to Rumble Studios’ original hit Bubble Gum Simulator (which racked up over 1.2 billion lifetime visits), is more than just a nostalgia play, it’s a breakout success in its own right. It’s currently a top 10 Roblox experience by concurrent users (CCUs) and monetization.
But what really sets it apart? Session length. Players are averaging 37.95 minutes per session, more than double the 17.24-minute average across Roblox’s other top 10 experiences. (Session length comparison based on the top 10 Roblox experiences by CCUs on May 4, 2025, averaged over the past 14 days)
So what’s keeping players hooked? Why are they spending more time here than almost anywhere else on the platform?
In this article, we’ll break down how Bubble Gum Simulator INFINITY sustains long play sessions through its genre foundations, a tightly layered core loop, and smart use of time-based rewards.
Inside Bubble Gum Simulator INFINITY: Roblox's Stickiest New Hit
Bubble Gum Simulator INFINITY is already making waves. To date, the experience has racked up:
205M+ lifetime visits
8.4M+ players who’ve earned the welcome badge (the easiest badge)
An average of 24 visits per unique player: a strong indicator of high retention and repeat engagement
Average session length of 37.95 minutes: exceptionally high for Roblox
Top 10 monetization ranking across the platform
At its core, Bubble Gum Simulator INFINITY blends quick progression, collection, exploration, and a layered reward system into a gameplay loop that feels more advanced than most Roblox experiences. Here’s a breakdown of its core mechanics:
Bubble Blowing: Players click to blow bubbles, generating in-game currency.
Pop and Sell: Bubbles are popped and sold for coins, which are then used to purchase upgrades. These upgrades increase bubble production (both speed and size). The larger the bubble, the higher players can jump, a core mechanic for unlocking new zones.
Automation & Scaling: Players invest in upgrades like bubble enhancements, pets, and multipliers. These systems gradually reduce manual input and accelerate progression.
Exploration & New Worlds: Improved jump height allows players to bounce on clouds and reach new worlds, each offering better resources and rewards.
Pet Collection: A secondary meta system where players hatch eggs to earn pets with powerful buffs.
Time-Based Rewards & Events: Daily login bonuses, timed rewards, and limited-time events provide consistent incentives to return, reinforcing longer sessions and increased retention.
The experience also monetizes exceptionally well, without relying heavily on pay-to-win mechanics. Its in-game economy includes a gem shop, various game passes, a premium battle pass, VIP areas, and premium pets. These monetization layers feel robust for a Roblox experience, driving revenue while maintaining accessibility for free players.
Why It Works: Layering in Progression Systems
The experience thrives not just because of strong brand recognition, but because it masterfully combines multiple proven game loops that promote extended play sessions, long-term retention, and effective monetization.
The Core of Simulator Appeal
Simulator games are a dominant genre on Roblox, and incremental simulators in particular tend to drive longer session lengths (as we’ll explore later). Sometimes called “clicker simulators," these games reward players for simple repeated actions (like clicking to blow bubbles) with in-game currency, encouraging players to stay longer in pursuit of upgrades and progression.
Collection as a Driving Force
Layered on top of that is a collection system centered around egg hatching and pet acquisition. Pets come in varying rarities (common to legendary), incentivizing players to keep grinding in hopes of completing their collections and unlocking ultra-rare companions. The gacha-inspired mechanic, often tied to trading and visible progression, taps into the completionist mindset where players need to “catch them all”.
Exploration as a Mini-Game
Progression isn’t just about numbers. As players blow bigger bubbles and improve their jump height, they gain access to floating worlds that can be reached by bouncing on clouds in a light, vertical platforming challenge. It feels almost like a simplified obby (obstacle course) mechanic layered into the simulator structure. It's reminiscent of Doodle Jump, the OG iPhone game, and this element adds a physical sense of progress and gives players a more active, skill-based way to unlock zones.
A Compounding Loop
These three systems: click-based resource generation, pet collection, and world exploration, form a compelling and repeatable core loop. Each layer feeds into the others, creating a continuous upgrade cycle that keeps players invested session after session.
Time-Based Incentives
One of the most effective drivers of longer session lengths in Bubble Gum INFINITY is its layered system of time-based rewards:
Playtime rewards: Players unlock rewards at intervals ranging from 2 minutes to 90 minutes, with better prizes the longer they stay. Progress resets if they leave the server, creating subtle pressure to remain logged in and playing.
Cooldown mechanics: Features like chests and hatchable eggs reset on timers, encouraging players to either stay longer or return later.
Daily challenges: Battle pass goals, quests, progress titles, and other time-gated challenges not only encourage return visits, but also incentivize players to stay longer in a given session as they work toward completion.
A Pattern Among Roblox's Longest Sessions
When analyzing the top 50 Roblox experiences by concurrent users on RoMonitor, a clear pattern begins to emerge: only six titles achieved an average session length above 30 minutes, and five of them were incremental simulators.
This isn't a coincidence.
Incremental simulators rely on compounding progression systems, layered reward mechanics, and time-based incentives, all of which naturally extend session length. These games are designed to keep players engaged by constantly offering something just around the corner: a milestone to reach, an egg to hatch, or a reward to unlock after a few more minutes of play.
The core loop isn’t flashy, but it’s undeniably effective: simple, repetitive actions tied to visible growth, often enhanced by light automation, collection mechanics, and upgrade systems. These games don’t demand constant input, but they make continued presence feel valuable.
Across the top-performing incremental simulators, one consistent mechanic stands out:
Idle progression or time-gated rewards.
Whether it’s earning rewards while doing nothing more than staying logged in, or unlocking bonuses on a countdown timer, these systems create frictionless incentives for players to keep the experience open and stay longer.
Layering in Progression Systems: Using Time-Based Rewards to Drive Engagement
Bubble Gum Simulator INFINITY proves that simple mechanics that are layered with smart progression systems and well-timed incentives, can drive exceptional engagement. Its success isn’t just about being a simulator; it’s about how time, progression, and rewards are intertwined to keep players coming back.
Even if a Roblox developer isn’t building an incremental simulator, there are still powerful design elements they can borrow, particularly time-based reward systems that drive longer sessions and more meaningful engagement.
What Developers Can Take Away:
Time-Based Rewards Work Across Genres You don’t need to build a simulator to benefit from timed mechanics. Systems like daily challenges, login streaks, or timed unlocks can fit seamlessly into RPGs, roleplay games, adventure games, and other genres, offering subtle incentives that encourage players to stay in the experience longer during each session.
Design Milestones Worth Waiting For Rewarding players simply for being present (e.g., unlock a rare item after 20 minutes) reinforces a feeling of progress without requiring intense input. It’s a low-friction, high-impact way to improve session length.
More Time = More Opportunity The longer someone stays in your experience, the more likely they are to engage with other features. Whether that’s cosmetics, badges, social features, microtransactions, or simply continuing to progress through the game. Time-based mechanics serve as scaffolding that supports deeper player discovery and extended session length.
In the end, developers don’t need to replicate the simulator genre’s core loop. But borrowing a few key retention mechanics that are popular in these types of games, especially time-based incentives, can make nearly any Roblox experience more engaging, sticky, and successful.
