7 Ways to Get More Pets in Pet Simulator 99 That Actually Work

May 5, 2026

11 min read

The fastest way to get more pets in Pet Simulator 99 is to rank up consistently, hatch eggs in the highest world you can access, and run the Daycare passively while you play. Combine those three habits with targeted minigame sessions, smart Trading Plaza deals, and understanding the real reward systems (not fake code lists), and your collection will grow significantly faster than grinding a single method alone.

Here is everything that actually works, broken down by what stage of the game you are in — updated for May 2026.

Why Most Players Stay Stuck With Too Few Pets

The biggest mistake players make in PS99 is spreading effort across everything at once. They hatch low-tier eggs in early worlds, ignore the Daycare, skip minigames, and waste hours testing fake codes from YouTube. Meanwhile, the game’s progression system is built around compounding — each improvement you make multiplies the returns of your other activities.

Ranking up doesn’t just feel good. It directly unlocks more permanent pet equip slots, which increases how much gem income you generate every second. More gems mean faster egg hatching in better worlds. It is a loop. Break into it correctly, and getting more pets stops feeling like a grind.

PS99 Codes Reality Check (May 2026)

Before we dive into pet farming methods, let’s clear up the biggest time-waster in the community: codes.

Are There Any Working Public Codes Right Now?

No. As of May 2026, the developers at BuildIntoGames have not released any free public promo codes for Pet Simulator 99. The in-game redemption system exists, but there are zero active codes that any player can redeem for free gems, boosts, or pets .

Expired & Fake Code List (Do Not Waste Your Time)

Every code you see on YouTube videos and copy-paste websites is expired or fabricated. Here are the most commonly circulated fake codes that will fail if you try them:

The Only Codes That Actually Work: Merch Codes

The only confirmed working codes in PS99 come from official BIG Games merchandise — physical plushies, toys, and collectibles sold through the BuildIntoGames store . Each merch code is single-use and tied to a specific item. Once redeemed, it becomes permanently invalid.

Sad Cat Plush	Titanic Electric Werewolf
Dino Cat Plush	Titanic Ancient Dragon
Blobfish Plush	Titanic Inferno Dominus
Monkey Plush	Titanic Inferno Dominus

Important: Pets obtained from merch codes have a 7-day trade hold — they cannot be traded immediately after redemption.

How to Redeem Codes (Desktop Only)

As of Update 4, code redemption only works on PC/Desktop:

Launch Pet Simulator 99 on Roblox (PC only).
Click the Shopping Cart icon to open the Exclusive Shop.
Scroll all the way to the bottom past Robux bundles and eggs.
Click the large green “Redeem” button.
Enter your merch code exactly as it appears (case-sensitive).
Click redeem to claim your exclusive pet/item.

Preston’s Super Secret Shop (Area 35)

After reaching Area 35, you will find Preston’s Shop with a prompt for a “Super Secret Code.” Despite rumors and fake YouTube videos, no valid public code has been discovered for this feature yet . Do not trust anyone claiming to have it.

How to Get More Pets in Pet Simulator 99: 7 Methods That Work

1. Rank Up to Unlock Permanent Equip Slots

This is the foundation. Every time you rank up, you permanently unlock additional pet equip slots, meaning more pets actively generating gems for you around the clock. No other method replaces this one.

Prioritize ranking up even when newer worlds look tempting. Players who rush to new areas before ranking up often find themselves under-powered and earning gems slowly. Completing rank requirements in your current world before moving on is almost always the more efficient path.

You can also purchase extra equip slots directly from the in-game shop using gems, which is worth doing once you’ve stabilized your ranking progress.

Pro Tip: Do not spend gems upgrading equip slots in the shop until you’ve ranked up as far as your current world allows. Shop slots are expensive; rank-based slots are free.

2. Always Hatch in the Highest World You Can Access

Pet power scales with the world where you hatch eggs. A rare pet from World 10 will outperform a legendary from World 3 in most cases. This matters because stronger pets mean faster area clearing, which means more gems, which loops back into faster hatching.

When specialists test egg hatching efficiency across PS99 worlds, the difference in gem multipliers between a mid-game world and the latest world is typically substantial enough to make early-world hatching a significant time waste past a certain progression point. Push to the latest accessible world, then hatch there exclusively.

May 2026 Update Context: With World 4 and the Grow Rainbow Pets update now live, hatching in the latest Fantasy World zones provides significantly higher base stats than legacy worlds

3. Use the Daycare for Passive Pet Gains

The Daycare is one of the most underutilized features in PS99 for newer players. Deposit pets there regularly and the system generates returns passively, including chances at huge pet rewards over time.

The typical failure point here is depositing weak pets and never checking back. Deposit your stronger pets when you can spare them, and check the Daycare consistently. Passive income in PS99 compounds over time, and the Daycare is essentially free progress running in the background while you do everything else.

Pro Tip: The Daycare has a soft cap on how many pets benefit simultaneously. Spreading deposits across sessions often outperforms a single large deposit.

4. Run Minigames: Chest Rush and Advanced Digsite First

Not all minigames pay off equally. Chest Rush and the Advanced Digsite offer some of the best reward-to-time ratios for farming pets, including chances at rare huge variants. The Jungle Obby, Minefield, and Claw Machine are worth visiting too, but treat Chest Rush as your primary rotation.

Common mistake: players try to complete every minigame every session and burn out. Pick two or three high-value ones and run them consistently instead.

5. Use the Huge Machine and Combine Machine

The Huge Machine converts exclusive pets into Huge Machine Eggs, one of the more reliable paths to huge pets outside of pure luck-based hatching. It requires specific pet types, so check which exclusives are currently accepted before grinding for them.

The Combine Machine lets you craft huge pets from smaller combinations. When game specialists test crafting efficiency, combining mid-tier pets intentionally rather than waiting for lucky hatches often produces faster results for players who are consistent about resource management.

6. Visit Secret Rooms Regularly

Secret rooms appear across multiple areas in PS99 — the Minefield, Atlantis, and Jungle Obby among them. These locations offer free pet chances, including huge pet opportunities that cost nothing but time.

They reset on a schedule, so building a quick rotation into your session habit pays off consistently. It is not flashy, but free huge pet chances add up over hundreds of sessions.

Pro Tip: Secret rooms in Atlantis have historically offered better huge pet odds than equivalent rooms in earlier areas. Verify this remains true in the current update cycle, as room odds shift with patches.

7. Buy Directly from the Trading Plaza

If you’re targeting a specific pet and RNG hasn’t cooperated, the Trading Plaza is the most direct solution. Players list pets at varying prices, and with enough gems you can fill collection gaps immediately rather than waiting on hatching luck.

Check the plaza regularly for underpriced listings. Active players often sell pets quickly to fund upgrades, and deals appear frequently.

Trading Safety Warning: Never trade off-platform. Scammers frequently promise to “double” pets or “verify” codes — these are all scams. Stick to the in-game trading system only

Pro Tips: What Most PS99 Guides Skip (May 2026 Edition)

From testing these methods across multiple progression stages and current updates:

Don’t chase codes. There are no working public codes right now. Every minute spent testing YouTube code lists is a minute not spent ranking up or hatching.
Auto-hatch and auto-tap settings are legitimate efficiency multipliers. Running them while AFK isn’t a shortcut; it’s how the system was designed to be used.
If Trading Plaza prices seem high for a target pet, wait 24-48 hours. Supply fluctuates heavily after update cycles and event conclusions.
World 4 Time Trial chests now offer competitive rewards (including Rainbow Shiny Gargantuan chances) without requiring any codes.
Diamond inflation is real. Smart traders buy Series 3 mystery eggs when prices dip and hold them until they become legacy items.
Group Rewards from the BIG Games Roblox group provide free boosts — this is currently the only legitimate “free” boost source outside of gameplay.

FAQ: Pet Simulator 99 Pet Questions

How do you unlock more pet equip slots in Pet Simulator 99? Rank up consistently — ranking is the primary permanent source of equip slots. You can also buy additional slots from the in-game shop with gems, but shop slots are significantly more expensive per slot than rank-based ones.

What is the fastest way to get huge pets in PS99? The Huge Machine and Combine Machine offer the most reliable paths. Minigames like Chest Rush and secret room visits add free chances on top of that. Pure egg hatching for huge pets involves significant RNG. Merch codes are the only guaranteed method but require real-money purchases.

How does the Daycare work in Pet Simulator 99? You deposit pets into the Daycare and receive them back after a set period, along with reward chances that include huge pets. The longer and more consistently you use it, the better the cumulative returns.

Can you get free pets without spending Robux in PS99? Yes. Secret rooms, minigames, the Daycare, Time Trial chests, and the Mailbox (claiming gifts from friends) all provide free pet opportunities. None of them require Robux.

What eggs should I focus on hatching in Pet Simulator 99? Always hatch in the highest world you can access. The pet power difference between early and late worlds makes hatching anywhere else a poor use of gems past mid-game.

Is trading the best way to get rare pets in PS99? For specific targeted pets, yes. The Trading Plaza is faster than relying on RNG. For general collection growth, combining regular hatching, Daycare, and minigames produces better overall variety.

Why do PS99 codes never work? Because there are no active public codes. The only working codes are single-use merch codes from physical products. Any “free code” you see online is either expired, fake, or already redeemed.

Your Next Steps (Action Plan)

Right now, open PS99 and check three things:

Your current rank requirements.
Whether your Daycare has pets deposited.
Which world you are currently hatching in.

Those three items alone will tell you where your biggest efficiency gap is.

After that:

Identify the highest world you haven’t fully cleared yet and set that as your next hatching target.
Build a daily session habit around Chest Rush and one secret room rotation.
Use the Trading Plaza only for pets you’ve been hunting specifically.
Stop testing codes — bookmark the official BIG Games Discord for the only legitimate source if public codes ever release.
