Bubble Gum Simulator INFINITY vs Pet Simulator 99 (2026) — Which Roblox Game Is Better?

Updated April 7, 2026 · 15 min read

Two of Roblox's biggest pet-collecting simulators are battling for your time in 2026, and they couldn't approach the genre more differently. Bubble Gum Simulator INFINITY from Rumble Studios has exploded onto the scene with 587 million visits, a staggering 1,497 pets to collect, and a bubble-blowing mechanic that sets it apart from every other simulator on the platform. Pet Simulator 99 from BIG Games has been dominating the charts since late 2023 with over 2.3 billion visits, a massive trading economy, and the kind of polish that comes from iterating on a franchise through dozens of versions.

Both games promise hundreds of hours of pet hatching, collecting, and upgrading without spending a single Robux. Both sit comfortably among the most-played experiences on Roblox. And both have communities that treat pet tier lists and value tracking like a second job. But the way they deliver on those promises — the feel of moment-to-moment gameplay, the pace of progression, the size of the pet roster, the role of codes and trading — differs enough that most players will find one fits them better than the other. This comparison breaks down every category that matters so you can pick your game, or figure out how to fit both into your rotation.

BGS INFINITY vs Pet Simulator 99 — Quick Stats (April 2026)

Gameplay — What Do You Actually Do?

Bubble Gum Simulator INFINITY

Bubble Gum Simulator INFINITY opens with something you won't find in any other Roblox simulator: you blow bubbles. Hold down the button, watch your bubble grow, and release it to float upward while collecting currency along the way. Bigger bubbles mean more coins, and the simple act of inflating and releasing creates a rhythmic loop that feels genuinely different from the tap-to-break formula that dominates the genre. It's a small mechanical distinction, but it changes the entire feel of the opening minutes.

The pet system is where BGSI flexes its ambition. With 1,497 pets currently in the game, the collection goal alone could keep you busy for months. Pets are hatched from eggs scattered across themed worlds, and each pet has stats that boost your bubble size, coin multiplier, and overall earning speed. The sheer volume of the pet index means there's always something new to chase — common pets fill out your collection while legendary and mythic-tier creatures represent genuine milestones that change how efficiently you progress.

Egg hatching in BGSI carries real weight because of the pet diversity. When you crack open an egg in a new world, the possible outcomes span dozens of species rather than a handful. That variance keeps the hatching loop engaging far longer than games with smaller pet pools, because the odds of seeing something you haven't collected before remain high even after hundreds of hatches. Rumble Studios clearly understood that collection depth is what separates a simulator you play for a weekend from one you play for months.

World progression follows a familiar but well-executed structure. Each new area unlocks with a currency threshold, introduces exclusive egg machines, and features breakable objects and collectibles tuned to your current power level. The jump between worlds feels significant — visual themes shift dramatically, pet pools expand, and the numbers escalate in ways that make your previous world feel like a warm-up. With Rumble Studios actively adding content, the world count keeps growing.

Codes play a bigger role in BGSI than in most Roblox games. With 50+ active codes available, new players can redeem a massive stack of free gems, luck boosts, hatching multipliers, and even exclusive pets before they blow their first bubble. Veteran players use codes to accelerate through new content drops and stack multipliers during grinding sessions. Rumble Studios drops codes through social media milestones, update celebrations, and community events at a pace that rewards players who stay plugged in.

Pet Simulator 99

Pet Simulator 99 drops you into a world packed with breakable objects — coins, chests, crystals, and loot crates spread across themed zones. You tap or click to smash them, collect the currency that spills out, and spend it at egg machines to hatch new pets. Every pet has a power level that determines how fast it breaks objects, and the straightforward loop of smash-collect-hatch forms the backbone of the entire experience. BIG Games has spent years refining this formula across dozens of Pet Simulator versions, and it shows. The feedback is instant, the animations are satisfying, and the ramp from your first pet to your first hundred happens faster than you'd expect.

Depth comes from what you do with those pets after hatching. Pets can be enchanted to gain bonus abilities like increased coin collection, faster breaking speed, or luck boosts that improve your odds on future hatches. You can fuse multiple pets together to create golden and rainbow variants with dramatically higher stats. The pet index tracks every species you've discovered, creating a completionist goal that extends beyond finding the single strongest creature.

Where Pet Simulator 99 truly separates itself is trading. Pets have community-driven values based on rarity, demand, and limited availability. Exclusive pets from past events, seasonal eggs, and promotional codes create scarcity that powers one of the most active trading markets on Roblox. Serious players track value lists maintained by community sites, negotiate in dedicated trading servers, and build portfolios of high-value pets the way collectors manage any other market. The social dimension adds an entire metagame on top of the core hatching loop that keeps veteran players engaged long after they've explored every world.

Game passes range from affordable quality-of-life upgrades to premium options that fundamentally change how the game feels. The Auto Tap and Auto Farm passes let you earn coins passively, turning extended sessions from active clicking into inventory management, trade browsing, and strategic planning. The VIP pass provides permanent perks. The monetization is more aggressive than most simulators, but the free-to-play path through every world and every pet species remains genuine.

Progression — How Fast Does It Hook You?

BGSI hooks you with novelty. The bubble-blowing mechanic means your first thirty seconds feel different from every other simulator you've played on Roblox. You hold, the bubble grows, you release, and currency rains down. Within two minutes you've hatched your first pet, and within ten you've probably redeemed a handful of codes that catapult your progress past the slow early grind that plagues many new simulators. The code system acts as an on-ramp — players who do their homework before loading in start with resources that would normally take hours to accumulate.

The mid-game stays compelling because of the pet index depth. With 1,497 pets in the game, you're constantly discovering new species even after dozens of hours. That discovery cadence matters. Where some simulators plateau once you've seen every pet variant and the only goal left is farming duplicates for fusion, BGSI keeps pulling new creatures out of its hat. Each world introduces exclusive pets you genuinely haven't seen before, which gives world progression a collecting dimension that smaller rosters can't match.

BGSI's average session time of 37.95 minutes tells a story about retention. Players aren't logging in for quick five-minute check-ins — they're settling into sessions that suggest genuine engagement. The 96.86% approval rating reinforces that. Players who try BGSI tend to like what they find, and they stick around long enough to reach the mid-game systems that reward investment.

Pet Simulator 99 hooks you through raw speed and spectacle. Your first pet hatches within sixty seconds. Every egg crack triggers flashy animations, rarity reveals, and the ever-present possibility of hitting something rare. BIG Games understands dopamine engineering — the visual feedback on every hatch is calibrated to make even common results feel momentous, while legendary and mythic pulls erupt with screen-filling effects that justify the grind.

The mid-game sustains engagement through world progression that constantly moves the goalposts. Just when your earnings plateau in one zone, the next world opens with bigger numbers, shinier eggs, and pets that make your current lineup look modest. Enchanting and fusing add incremental power gains that stack on top of world progression, so there's always something to optimize between major milestones.

Where Pet Simulator 99 has a genuine advantage is the trading metagame. Once you've progressed deep enough to own pets with real market value, the game transforms. You're no longer just hatching — you're evaluating, negotiating, and building a portfolio. That shift gives veteran players a reason to log in that has nothing to do with world progression, and it creates a self-sustaining engagement loop that doesn't depend on content updates to stay interesting.

Edge: BGSI for collection depth and code-powered onboarding. Pet Simulator 99 for instant feedback and the trading-driven endgame. If you want the biggest pet index to chase and a generous code system that rewards new players, BGSI delivers. If you want the fastest hook and a social economy that extends playtime indefinitely, Pet Simulator 99 has the edge.

Pet Collection and Variety

This is the category where Bubble Gum Simulator INFINITY makes its strongest case. 1,497 pets is a number that's hard to argue with. That's not padding with minor reskins — the pet index spans common creatures, rare finds, legendary pulls, mythic-tier trophy pets, and event exclusives that only appeared during limited windows. The breadth of the collection means every play session has a realistic chance of adding something new to your index, even after you've logged dozens of hours.

The variety matters for engagement in a way that raw numbers alone don't capture. When you approach an egg machine in BGSI, the possible outcome space is wide enough that anticipation stays high. You're not cycling through the same twelve possibilities hoping for the one you don't have — you're rolling against a pool deep enough that surprises remain common. For players who are motivated by the "gotta catch them all" impulse, BGSI's roster is one of the most compelling on Roblox.

Pet Simulator 99 has a smaller but carefully curated collection that grows with each update. BIG Games Pets adds new species through world expansions, seasonal events, and exclusive promotions. The roster doesn't match BGSI's raw numbers, but each pet feels individually designed with distinct visual identity and stat profiles. The enchanting and fusion systems add layers on top of the base collection — a golden enchanted pet is functionally and visually distinct from its standard version, which multiplies the effective variety within a smaller species count.

The trade-off is straightforward. BGSI gives you more pets to discover. Pet Simulator 99 gives you more to do with each pet you find. Players who measure satisfaction by index completion and discovery frequency will prefer BGSI. Players who care about optimizing, upgrading, and trading individual pets will find Pet Simulator 99's approach more rewarding per pet.

Edge: Bubble Gum Simulator INFINITY, clearly. Nearly three times the pet count gives it an undeniable advantage in collection variety. If the size of your pet index is what keeps you logging in, BGSI wins this category by a wide margin.

Codes and Free Rewards

Rumble Studios treats codes as a core feature rather than an afterthought, and it shows. Bubble Gum Simulator INFINITY has over 50 active codes that players can redeem for gems, coins, luck boosts, hatching speed multipliers, and exclusive pets. New codes drop regularly through Twitter announcements, Discord milestones, YouTube celebrations, and in-game events. The volume and value of BGSI's code system is genuinely unusual for a Roblox simulator — most games in the genre offer five to fifteen active codes at any given time. BGSI triples that and keeps the pipeline flowing.

For new players, this code library is transformative. Redeeming the full stack of active codes before your first real play session gives you enough resources to skip the earliest grind entirely. Luck boosts from codes improve your hatching odds immediately. Gem payouts let you access egg machines that would normally require hours of currency farming. It's one of the most generous new-player experiences on the platform, and it creates positive first impressions that contribute to that 96.86% approval rating.

Pet Simulator 99 takes a different approach to codes. BIG Games distributes codes through merchandise partnerships, special promotions, and periodic social media drops rather than maintaining a large active library. The codes that do exist are valuable — often providing exclusive pets or significant currency boosts — but there are far fewer of them at any given time. The game's economy is structured more around gameplay progression and game pass purchases than around code redemption as a regular reward mechanic.

Merch codes in Pet Simulator 99 deserve a specific mention. Physical merchandise like plush toys and figurines come with redemption codes for exclusive in-game pets that can't be obtained any other way. These pets carry significant trade value in the community economy, which means merch codes serve double duty as both collectibles and trading currency. It's a clever monetization strategy, but it does mean that some of the most desirable pets are locked behind real-world purchases rather than gameplay.

Edge: Bubble Gum Simulator INFINITY, decisively. The sheer volume of active codes, the generosity of the rewards, and the impact on new-player onboarding make BGSI's code system one of the best on Roblox. If free rewards matter to you, this isn't close.

Graphics and Audio

Pet Simulator 99 is a visual spectacle by Roblox standards. Every pet hatch triggers particle effects, light bursts, and rarity-specific animations that make even common results feel momentous. Worlds are individually themed with distinct color palettes, environmental details, and breakable object designs. The overall aesthetic is polished, playful, and intentionally over the top. BIG Games has the resources and experience of a franchise that's been refining its visual identity for years, and Pet Simulator 99 looks like the product of that investment.

Audio follows the same philosophy — coin collection creates rapid-fire chimes that build into a satisfying cacophony as your pet army shreds through objects. Egg hatches have dramatic sound cues that escalate with rarity. Background music shifts between worlds to keep things fresh during long sessions. The game is designed to feel exciting at all times, and the sound design reinforces that intention at every level.

Bubble Gum Simulator INFINITY brings its own visual personality. The bubble mechanics create a playful, colorful aesthetic that's distinct from the smash-and-collect look of most simulators. Bubbles inflating and floating upward add vertical motion to a genre that usually stays ground-level, and the particle effects on bubble pops create satisfying visual feedback. Worlds are themed with bright, varied environments that shift dramatically as you progress. The pet designs across 1,497 species range from cute to absurd to genuinely impressive, and the visual variety keeps the collection screen interesting in a way that smaller rosters can't.

Where BGSI's presentation shines is in personality. The bubble-blowing animations give the game a character that's harder to find in Pet Simulator 99's more polished but more conventional presentation. It feels like a game with a specific creative vision rather than a genre template executed at a high level.

Edge: Pet Simulator 99 for pure production polish. Bubble Gum Simulator INFINITY for visual personality and charm. Pet Simulator 99 is the game you'd show someone to demonstrate what a high-budget Roblox simulator looks like. BGSI is the game that surprises you with how much character a bubble-popping mechanic can carry.

Player Count and Community (April 2026)

Pet Simulator 99 holds the numbers advantage here with 2.3 billion total visits and consistently high concurrent player counts. The BIG Games brand carries weight — the Pet Simulator franchise has been one of the most recognizable names on Roblox for years, and version 99 inherited a massive audience. The community is large, vocal, and heavily oriented around trading. Discord servers dedicated to pet values run around the clock. YouTube content creators produce daily videos covering new updates, trading tips, and pet tier lists. The social infrastructure is substantial.

Bubble Gum Simulator INFINITY has 587 million visits — a strong number by any standard, even if it doesn't match Pet Simulator 99's scale. The more telling statistic is the 96.86% approval rating, which places it among the highest-rated simulators on the platform. Players who discover BGSI tend to approve of what they find, and that satisfaction translates into a community that's enthusiastic rather than just large. The original Bubble Gum Simulator built a significant following, and the INFINITY relaunch has been recapturing that audience while bringing in new players.

Community culture differs between the two. Pet Simulator 99's community moves fast — update drops change the meta, shift trading values, and generate waves of content within hours. BGSI's community is more discovery-oriented, sharing code lists, pet index progress, and world exploration tips. Both communities are welcoming to newcomers, but the type of engagement you'll find reflects the games themselves: trading and market analysis in Pet Simulator 99, collecting and code sharing in BGSI.

Edge: Pet Simulator 99 for raw size and social infrastructure. BGSI for player satisfaction rate and community warmth. If you want the biggest possible pool of trading partners and content creators, Pet Simulator 99 is the clear pick. If you care about joining a community that genuinely loves the game it's playing, BGSI's 96.86% rating speaks for itself.

Game Passes and Monetization

Pet Simulator 99 offers a wider range of game passes at higher price points. The VIP pass at 400 Robux provides permanent perks. The Lucky pass at 175 Robux improves hatching odds. Auto Tap and Auto Farm passes transform the gameplay from active clicking to passive collection, which many players consider essential for longer sessions. The most expensive passes reach up to 3,250 Robux. The monetization is more aggressive than most simulators, but BIG Games maintains a genuine free-to-play path through every world and every pet species. Nothing is locked behind a paywall — the passes accelerate progress and reduce grind.

Bubble Gum Simulator INFINITY takes a lighter approach to monetization. Game passes exist for quality-of-life upgrades and boosted progression, but the pricing stays moderate and the free-to-play experience doesn't feel deliberately friction-heavy to push purchases. The 50+ code system functions as a parallel reward track that's entirely free — new players who redeem codes get resource boosts that rival what game pass buyers receive in the early game. That balance between paid passes and free codes creates a monetization model that feels generous by Roblox simulator standards.

The philosophical difference is noticeable during extended play. Pet Simulator 99 is designed so that game passes feel like natural upgrades you'll want — the gap between active tapping and auto-farming is significant, and watching other players progress faster with passes creates visible incentive. BGSI is designed so that codes and regular gameplay provide enough momentum that game passes feel optional rather than aspirational. Neither approach is wrong, but they appeal to different spending temperaments.

Edge: Bubble Gum Simulator INFINITY for free-to-play friendliness and value. Pet Simulator 99 for variety of paid options. If you prefer spending nothing and never feeling behind, BGSI's code system and lighter monetization make it the safer bet. If you don't mind spending Robux on passes that genuinely improve the experience, Pet Simulator 99 offers more customization through purchases.

Trading

Pet Simulator 99 has one of the most developed trading economies on Roblox, and it's the single biggest differentiator between these two games. Every pet has a community-driven value based on rarity tier, limited availability, and current demand. Exclusive pets from past events, merch codes, and seasonal hatching windows create genuine scarcity. Experienced traders track value lists updated daily, negotiate in dedicated servers, and build portfolios worth thousands of Robux in equivalent trade value. The trading interface includes confirmation steps to help prevent scams, and the social aspect of finding partners and reading market trends adds an entire gameplay dimension that exists outside the hatching loop.

Bubble Gum Simulator INFINITY supports pet trading, and with 1,497 pets in the game, there's no shortage of things to exchange. Rare and exclusive pets carry real demand within the community, and the trading scene is active and growing. That said, the trading infrastructure isn't as mature as Pet Simulator 99's established ecosystem. Community value lists exist but aren't as granular or frequently updated. Dedicated trading servers are emerging but haven't reached the scale of Pet Simulator 99's trading community. For a game that's still building its player base, the trading foundation is solid — it just needs time to develop the depth that comes with a larger, more established economy.

Edge: Pet Simulator 99, clearly. If player-to-player trading and market dynamics are a major part of why you play Roblox simulators, Pet Simulator 99 offers one of the richest trading experiences on the platform. BGSI's trading scene has potential and is improving, but it doesn't match the depth or activity level yet.

Replay Value — Will You Still Be Playing Next Month?

Bubble Gum Simulator INFINITY's replay value is anchored in the size of its collection goal. With 1,497 pets, completing the index is a project measured in months rather than weeks. Rumble Studios keeps the target moving by adding new pets, worlds, and codes through regular updates. The code pipeline alone creates a reason to check in regularly — missing a limited-time code means missing free resources, which creates a gentle pull that keeps players returning without the aggressive FOMO of event-exclusive content that disappears forever.

The average session time of 37.95 minutes suggests that individual sessions are substantial and engaging. Players aren't bouncing after five minutes — they're settling in for meaningful progression blocks. The 96.86% approval rating indicates that the experience holds up over time rather than front-loading excitement that fades after the first few hours. Rumble Studios has built a game that respects long-term investment.

Pet Simulator 99 maintains replay value through rapid update cadence and the self-sustaining trading economy. BIG Games pushes new content frequently — new worlds, egg machines, limited-time events, and exclusive pets arrive at a pace that keeps the game fresh. Each update reshuffles part of the trading market, creating new opportunities for engaged players. The trading metagame generates organic replay value because pet values shift constantly, rewarding regular engagement even when you've explored every world.

The risk with Pet Simulator 99's approach is content treadmill fatigue. When a game relies on constant additions to stay interesting, missing a few updates can make you feel behind. Limited-time pets create FOMO that motivates some players and exhausts others. BGSI's replay value feels more sustainable because the collection goal is so large that you're never "caught up" — there's always more index to fill, more codes to redeem, and more worlds to explore at your own pace.

Edge: Both games deliver long-term value through different mechanisms. BGSI's massive pet index provides a personal collection goal that sustains months of engagement. Pet Simulator 99's trading economy creates a social engagement loop that refreshes itself with every market shift. Pick the style that matches how you play.

Earning Potential — Free Robux While You Play

If you use Earnaldo to earn Robux alongside your gaming sessions, both Bubble Gum Simulator INFINITY and Pet Simulator 99 create natural windows for multitasking. The key is identifying idle moments where you're waiting rather than actively playing, and using those gaps to complete quick tasks on Earnaldo's earn page.

Bubble Gum Simulator INFINITY creates these windows in several ways. While your bubble inflates to maximum size, you've got a few seconds of downtime. Between egg hatches, while currency accumulates, and during world transitions, there are natural pauses that add up over a session. BGSI's 37.95-minute average session means you're playing long enough for those pauses to translate into meaningful earning time on Earnaldo. The rhythm of blow-collect-hatch-repeat creates a predictable cadence that makes it easy to slip earning tasks into the gaps without losing progress.

Pet Simulator 99 offers similar opportunities, especially for players with Auto Tap or Auto Farm passes. When your pets grind coins passively, you can switch to Earnaldo and complete tasks without any in-game penalty. Even without those passes, natural breaks between world transitions, after clearing an area of breakables, and during server-hopping for trades provide earning windows. The trading phase itself — browsing listings, evaluating offers, waiting for trade partners — often involves enough downtime to multitask.
