If you’re hunting for working Pet Simulator 99 codes because you just hit Diamond Plaza and you’re scrambling for free Huge pets or Titanic eggs to keep up with the leaderboard grind, I have to be straight with you: BIG Games does not run public codes the way most Roblox games do. Here’s everything that’s actually working in May 2026 and what to ignore.
Here’s what’s inside:
- The current PS99 code status (zero public codes active)
- Why merch codes are the only real freebie path
- How to redeem PS99 codes step-by-step (the menu’s hidden)
- Every “secret code” YouTube video lying to you, and why
- The full expired-code dump so you don’t waste tries
- Where actual codes drop when they exist
I learned the hard way that pasting Pet Simulator X merch codes into PS99 does absolutely nothing. They don’t carry over. The two games have separate code systems. That regret is the framing for everything below.

All Pet Simulator 99 Codes for May 2026
Here’s the active code list as of May 2026:
| Code | Reward | Status |
|---|---|---|
| (None public) | — | No active public codes |
That’s the truth. There are no active public Pet Simulator 99 codes. Independent code trackers (game.guide, PCGamesN, Roblox Den, Pocket Tactics) all confirm zero active codes for the game right now. The last cluster of expired codes was added around March 23 of 2026, and they all rolled off shortly after.
If you’re seeing aggregator sites listing 19 active codes, those are scraped lists that haven’t been updated. Cross-reference any code you find against the BIG Games Discord announcements channel before you bother typing it in.
Why Pet Simulator 99 Doesn’t Have Codes Like Other Roblox Games
BIG Games (the developer) handles freebies differently from games like Anime Adventures or Jujutsu Shenanigans. Instead of regular code drops every update, PS99 mostly uses two systems:
Merch codes from physical products. When you buy Pet Simulator merchandise (plushies, mystery boxes, figures from the BIG Games store or licensed retail toys), each product has a tag with a unique code. These codes redeem for exclusive in-game pets, hoverboards, or potions. The catch: each code only works once, on one account, ever.
Promotional event codes during major launches or milestones. BIG Games occasionally drops time-limited public codes for big events (anniversary, world launches, plushie line releases). These appear in Discord first and expire within hours or days.
The reason this system exists is the in-game economy. PS99 has a Trading Plaza where Titanic and Huge pets hold real value. If BIG Games handed out Titanic Fire Dragons through public codes, those pets would crash in trading value overnight. Limiting freebies to merch buyers keeps the rare pet supply controlled.
How to Redeem Pet Simulator 99 Codes Step-by-Step
The redeem menu is buried at the bottom of the in-game shop, which trips up almost every new player. Here’s the actual flow:
- Launch Pet Simulator 99 on Roblox.
- Tap the pet grid button at the bottom of the screen.
- Click the Shopping Cart icon that appears after tapping the grid. This opens the in-game store.
- Scroll all the way down past every Robux bundle and egg listing. The Redeem banner is at the very bottom of the menu.
- Tap the green Redeem button in the banner. A text box pops up.
- Type or paste your code exactly as it appears on the merch tag (codes are case-sensitive). Don’t add spaces.
- Hit Redeem again to claim your reward.
If a code is invalid, expired, or already used, the game tells you immediately with an error message. No guessing required. If you get “Code Already Redeemed,” the code was a one-time use that someone already claimed, which happens with shared YouTube codes constantly.
Every “Secret Code” YouTube Video Is Lying to You
This is the part most code guides won’t admit. There are dozens of YouTube videos with titles like “Pet Simulator 99 SECRET CODE for FREE Huge Cat” or “Working PS99 Code April 2026” that have racked up tens of thousands of views.
I tested codes from the most popular of these videos. None of them worked. Every single one returned “Invalid Code” or “Code Already Redeemed.”
Here’s why most of these fake codes show up:
- They’re personal merch codes that the YouTuber redeemed already on stream. The code worked once for them, then got copied by everyone else trying it after.
- They’re outright fabricated strings to farm video views.
- They’re old test codes from beta or developer testing that never went public.
- They’re recycled from Pet Simulator X, which has its own separate (and now mostly dead) code system.
A short list of fake “PS99 codes” you’ll see promoted that don’t work:
- S7MJHEKAABC8
- pet-d67518012
- HUGECAT2025
- DIAMOND2026
- PRESTONSHOP
Skip the YouTube hunt. The only real codes come from physical merch tags or BIG Games’ official channels.
Past PS99 Codes That Are All Expired
The expired code pool gives you a sense of what BIG Games has offered when codes did exist. Don’t bother trying these, they all return invalid:
| Past Code Reward | Type |
|---|---|
| Titanic Fire Dragon | Merch / event exclusive |
| Huge Celestial Dragon | Merch exclusive |
| Huge Unicorn Dragon | Merch exclusive |
| Huge Axolotl Pet | Merch exclusive |
| Huge Dog Pet | Merch exclusive |
| Cat Hoverboard | Merch exclusive |
| Balloon Hoverboard | Merch exclusive |
| Exclusive Dragon Egg | Merch exclusive |
| Bag of Diamonds | Promotional |
| Lucky Potion V | Promotional |
| Damage Potion V | Promotional |
Most of these were one-time merch tag rewards, which means even if you got hold of the original code string, it’s already been redeemed by whoever bought the toy. Once consumed, the code is permanently dead for that account ID.
Where to Actually Find Working Codes
If you want a chance at real PS99 codes, three sources are worth watching:
- BIG Games Discord (Announcements and Update-log channels). This is the fastest source for time-limited public codes. They drop in announcements before anywhere else and disappear within hours.
- BIG Games X (Twitter) account. Set up notifications on their main account. Codes occasionally appear in posts, especially around milestones. You’ll get non-code posts too, but it’s worth the noise.
- Physical Pet Simulator 99 merch. Buy plushies, mystery boxes, or figures from the BIG Games store or licensed retail. Each product has a unique code tag. They sell out fast.
Note that codes from Pet Simulator X merch may also work in PS99 in some cases, but the policy has been inconsistent. BIG Games told players in earlier games to “keep your codes for use in future games,” but PS99 launched with a partial reset of merch redemption logic. Test PSX codes if you have them, but don’t expect them all to convert.
What the “Super Secret Preston’s Shop Code” Actually Is
You’ll see sites and videos hyping a “super secret code” for Preston’s Shop in PS99. The truth: nobody publicly knows it. Every site claiming to have it is fabricating content for clicks.
If a real super secret code exists, it’s either tied to a specific in-game easter egg that hasn’t been solved yet, or BIG Games hasn’t activated it. The bragging rights of being the first to share it would make any genuine discovery viral within hours, and that hasn’t happened. Stop searching for it.
Free Boosts You Can Actually Get Without Codes
Codes are dry, but PS99 has multiple ways to grind value without spending Robux:
- Daily Login Streak rewards stack the longer you log in consecutively. Don’t break the streak or you reset. Bigger rewards arrive at 7, 14, and 30-day milestones.
- Time Trial chests introduced in recent updates give boosts and rare pets if you hit the speed thresholds in challenge zones.
- World 4 Diamond X enchant farming is the current best path for pure gem income. Stack Diamond X on your top pets and grind in the latest zones.
- Fortune Flag rotations during events significantly boost luck for limited windows. Time your egg hatching around active flags.
- Trading Plaza arbitrage. Buy underpriced pets and resell. The Plaza market has real inflation right now, so flipping is more profitable than it used to be.
None of these replace a public code drop, but stacked together they’re the realistic F2P progression path while waiting for codes that may never come.
FAQ
Are there any working public Pet Simulator 99 codes right now?
No. As of May 2026, there are zero active public codes. Independent trackers across multiple sites confirm this. BIG Games hasn’t released a public code since the March 2026 cluster all expired. The merch code system is the only currently active redemption path.
Can I use my Pet Simulator X merch codes in PS99?
Sometimes, but the policy has been inconsistent. BIG Games said in PSX days to save merch codes for future games, but PS99 launched with partial reset logic on which codes carry over. If you have unused PSX codes, try them in PS99 first before assuming they don’t work, but don’t be surprised if some return invalid.
Why does the Redeem button say “Code Already Redeemed” when I haven’t used it?
Because someone else used it first. Merch codes are one-time-use across the entire Roblox account system. If you found the code in a YouTube video or shared list, the original owner (or anyone who saw the video before you) already burned it.
Where exactly is the Redeem button in PS99?
At the very bottom of the in-game store. Open the shopping cart icon, scroll past every Robux bundle and egg, and you’ll see a banner with a green Redeem button. New players miss it because the menu is long and the banner doesn’t appear at the top.
Do PS99 plushies and toys sold in physical stores actually have working codes?
Yes, real merchandise from BIG Games (sold through their official store and licensed retail) comes with valid one-use codes on the tag. Codes from secondhand or sketchy resellers might already be redeemed, so buy new and sealed if you want guaranteed working codes.
Will BIG Games ever release public codes for PS99?
They have in the past for milestones and event launches, and they likely will again for major updates or anniversaries. The next likely window is around the next World launch or a big seasonal event. Watch the Discord announcements channel since that’s where any future public codes drop first.
Is there a code for the Titanic Fire Dragon that still works?
No. Every code that historically rewarded a Titanic Fire Dragon was tied to specific limited merch and has long since been redeemed. The only way to get one in 2026 is through trading on the Plaza or hatching it from the relevant Titanic egg.
Final Take
That’s the honest state of Pet Simulator 99 codes for May 2026. The headline takeaway: there are no active public codes, every YouTube “secret code” video is lying to you, and the only real freebie path is buying physical PS99 merch with codes on the tag. BIG Games keeps the in-game economy controlled by limiting public codes, which is annoying for F2P players but keeps Titanic and Huge pets valuable.
Bookmark the BIG Games Discord announcements channel and turn on notifications. If a public code ever drops, you’ll have minutes to claim it before it spreads and burns out. Until then, focus on Diamond X farming, Daily Login streaks, and Trading Plaza arbitrage to actually progress.
