There is no public Pet Simulator 99 promo code from BIG Games right now. We checked BIG Games’ own pages, the game’s Roblox page and its official event listings on November 5, 2026 at 20:05 UTC, and none of them shares a code anyone can type in. Pet Simulator 99 does have a code box, but BIG Games only uses it for merch codes and for promo codes it gives out through creator campaigns.
The good news is that this week’s Halloween Games update (Update 100) is packed with free Huge pets you can earn by playing. Most of them disappear when Update 101 arrives on Saturday, November 7 at 17:00 UTC, so this page lists every one, with end times.

Quick answer
- Working Pet Simulator 99 codes: none confirmed by BIG Games as of November 5, 2026, 20:05 UTC.
- Where codes go: the Exclusive Shop. Promo codes work once per account after you have played for at least 5 minutes, according to BIG Games’ FAQ.
- Free Huge this week: the Huge Guard Bat at Tier 4 of the Season Pass. The official “FREE HUGE!” listing ends Saturday, November 7 at 16:55 UTC.
- More free Huges: three from the Forge, one from the last zone egg, one from Midnight Gifts and the Huge Witch Cat from PSX Classic’s Cursed Egg.
- Deadlines: Halloween Leaderboard scoring ends November 6; the Halloween Games listing ends November 7 at 17:00 UTC, when the next update is due.

Are there any Pet Simulator 99 codes right now?
No. BIG Games has not posted a public promo code for Pet Simulator 99 on its site, its Roblox game page or its event listings. Its FAQ explains why the code box exists anyway: “Pet Simulator 99 has merch codes, which come with official BIG Games merch, and promo codes, which we share through campaigns with creators.” The same answer warns that sites promising free codes for pets or diamonds are not BIG Games’, and tells players never to type a password or download anything to get a code.
Two kinds of codes exist, and neither is a giveaway for everyone:
| Code type | Where it comes from | Where you enter it | Limits |
|---|---|---|---|
| Promo code | Campaigns with content creators (BIG Games FAQ) | Exclusive Shop | Once per account, after 5 minutes of play |
| Merch code | Official BIG Games merch | Exclusive Shop, Official Merch, Redeem | Once, on one account; computer only, not phone or tablet |
The merch side has changed too. The BIG Games Merchandise FAQ says online store orders no longer come with DLC. Digital rewards now come from buying merch inside the game through the “Official Merch” button next to the Exclusive Shop, and only US-based players aged 13 or over (18 in Texas) can buy there. If a recent Classic Plush Pack, Tech Plush Pack or Pet Rug order came with a printed code that doesn’t work, the FAQ says that code “is not meant to be used and is inactive”.
What about the codes on other code sites?
Code trackers don’t agree. Pocket Tactics (updated April 29, 2026) and PCGamesN (updated June 7, 2026) both say there are no Pet Simulator 99 codes. Bloxodes (checked November 5) lists one code, HACK777, for a Random Gift, added October 20, and Roblox Den (checked November 5 at 19:55 UTC) lists the same code as active, plus several pet-name strings marked “Check”. We could not find HACK777 or any of those strings on any BIG Games channel, so we don’t list them as working. If a code ever asks you to log in somewhere outside Roblox, it is a scam.
How to redeem a Pet Simulator 99 code
When BIG Games or a creator campaign does hand out a code, here is how BIG Games says to use it:
- Play Pet Simulator 99 for at least 5 minutes on the account you want the reward on.
- Open the Exclusive Shop.
- For a promo code, type it into the code box in the Exclusive Shop. For a merch code, go to Official Merch, press Redeem and type the code.
- Redeem merch codes on a computer. BIG Games says merch redemption doesn’t work on phones or tablets.
- If a merch code fails, BIG Games points you to Epic Drops’ DLC help desk, not to its own Discord staff.
Free Huge pets in Pet Simulator 99 this week (Update 100)
Update 100, Halloween Games, went live on October 31 at 16:00 UTC. You climb the haunted door steps to join a match, then try to survive 6 minigames in a row against 40 players. The longer you last, the more Treats and Midnight Gifts you win. We covered the launch time in our Pet Simulator 99 Halloween Update 100 start time guide. Here is every Huge the official notes list, and how you get each one:
| Huge pet | How to get it (BIG Games notes) | Costs Robux? |
|---|---|---|
| Huge Guard Bat | Reach Tier 4 of the Season Pass | No |
| Huge Guard Elephant | First Huge from the Forge | No |
| Huge Trick Or Treat Piggy | Second Huge from the Forge | No |
| Huge Bedsheet Giraffe | Third Huge from the Forge | No |
| Huge Guard Rhino | Hatch the last zone egg (chance) | No |
| Huge Neon Skeleton Dino | Open Midnight Gifts (chance) | No |
| Huge Witch Cat | The Cursed Egg in PSX Classic (chance) | No |
| Huge Frankenpet Monkey | Finish 1,004th to 10,000th on the Halloween Leaderboard | No |
| Huge Butler Penguin, Huge Chrome Axolotl, Huge Chrome Monkey | Forever Pack and Exclusive Chrome Egg | Yes |
Season Pass Week 4: the Huge Guard Bat
The official Roblox listing “🧡 FREE HUGE! 🖤” (Season Pass Week 4) promises “a FREE mystery HUGE PET”, a new booth and hoverboard, diamonds, boosts and potions, and warns that the rewards are “available only this week”. The Update 100 notes name the mystery pet: reach Tier 4 for a free Huge Guard Bat, plus the Treat Booth and Treat Hoverboard. You earn Season Tokens by finishing event quests. The listing runs from October 31, 16:05 UTC to November 7, 16:55 UTC.
The Forge: three Huges, then a Titanic roll
At the Forge you brew pets into Huge pets. The notes list the order: Huge Guard Elephant first, Huge Trick Or Treat Piggy second, Huge Bedsheet Giraffe third. After that you roll for the Titanic Neon Skeleton Cat and the Gargantuan Butler Penguin. Spirit Shards, which you earn by surviving games, add luck to the roll. BIG Games says only 3,000 Titanics come out of the Forge, “a few every hour”.

Zone eggs, Midnight Gifts and PSX Classic
- Zone eggs: the haunted farm has 5 zones, each with a new egg you hatch with Candy Coins from breakables. The last egg holds the Huge Guard Rhino. Every zone hits harder, so bring your strongest team.
- Midnight Gifts: winning a match gives “a big stack” and finishing near the top still pays a share. They contain Treats, Candy Coins, Tricks and the Huge Neon Skeleton Dino.
- PSX Classic: the 2021 Halloween world is back for a limited time behind the spooky door in Town. Its Cursed Egg hides the new Huge Witch Cat, and every one you hatch also comes home to PS99.
Halloween Leaderboard and Ender Clan Battle prizes
You climb the Halloween Leaderboard by winning the most Treats in the games. The notes say scoring ends on November 6, without a time, so don’t leave it to the last evening.
| Halloween Leaderboard place | Prize |
|---|---|
| #1-3 | Gargantuan Butler Penguin |
| #4-6 | Rainbow Shiny Titanic Trick Or Treat Hippo |
| #7-13 | Golden Shiny Titanic Trick Or Treat Hippo |
| #14-103 | Rainbow Titanic Trick Or Treat Hippo |
| #104-253 | Shiny Titanic Trick Or Treat Hippo |
| #254-503 | Golden Titanic Trick Or Treat Hippo |
| #504-1,003 | Titanic Trick Or Treat Hippo |
| #1,004-10,000 | Huge Frankenpet Monkey |
The Ender Clan Battle runs for 6 days. Clans earn points by farming Treats and more in the Halloween Games. The top clan wins the Gargantuan Warrior Wolf; places 2-50 get Titanic Ender Goats (Rainbow for 2-3, Golden for 4-10), and places 51-250 get the Huge Ender Bunny. Every member of a winning clan gets the prize.
What to do first before Saturday
- Finish the Season Pass to Tier 4 for the Huge Guard Bat before November 7, 16:55 UTC.
- Brew your three Forge Huges (Elephant, Piggy, Giraffe) and keep the Spirit Shards you earn from surviving games for the Titanic roll.
- Push the leaderboard before November 6 if you’re near the top 10,000.
- Turn on the new Security PIN in Settings. Update 100 added it: once set, unlocking or boxing a locked pet needs your PIN, and setup can lock every Huge, Titanic and Gargantuan in one tap. A reset takes 3 to 14 days. “Never share your PIN. Staff will never ask!”
- Plan your trades: Halloween Games pets stay untradable until November 7.
| Deadline | UTC | US Eastern (EST) | US Pacific (PST) | UK (GMT) |
