All Pet Simulator 99 Codes — Free Diamonds & Boosts

Searching for Pet Simulator 99 codes? You have probably already seen dozens of YouTube videos and blog posts listing codes like TitanicFireDragon and BagOfDiamonds. We tested every single one of them. None of them work.

Here is what most sites refuse to tell you: BIG Games has never released free public promo codes for PS99. Not once. Every “working code” floating around the internet is either completely fabricated, an already-redeemed merch code, or straight-up clickbait designed to waste your time.

But do not close this tab yet. This guide covers everything that actually matters — the only real codes that exist (merch codes), exactly how to redeem them, the fastest diamond farming strategies, and a full best pets tier list. We update this page regularly because we actually play PS99, and we refuse to lie to you.

Pet Simulator 99 Codes — Full Status

Let’s get the code situation laid out clearly so you know exactly where things stand right now.

Active Working Codes

That is the entire list. There are zero free public promo codes for Pet Simulator 99. The only active codes are unique single-use codes that come bundled with official BIG Games merchandise. Each code is tied to one account and cannot be shared.

We check for new codes daily. If BIG Games ever decides to release free public codes, this table will be the first place we update.

Why There Are No Free Codes

This surprises a lot of players because most popular Roblox games hand out free codes regularly. Blox Fruits gives out codes every update, Anime Vanguards drops them for milestones, and even smaller games use codes as a marketing tool.

BIG Games does things differently. Their revenue model focuses on in-game purchases and official merchandise sales. Free promo codes would undercut both of those revenue streams, so they have never offered them. Multiple trusted sources — Game Rant, PCGamesN, Pocket Tactics, and The Gamer — have all independently confirmed this.

So if you see a website listing ten or more “working PS99 codes,” that website is lying to get your clicks.

Fake Codes You Should Avoid

These codes appear on clickbait sites constantly. We tested all of them. Every single one is fake or expired:

Codes starting with pet- followed by a string of letters and numbers (like pet-d67518012 or pet-45a33a2dca) are real merch codes — but they have already been redeemed by whoever originally purchased the merchandise. They are single-use. Once claimed, they are dead forever.

Similarly, codes like S7MJHEKAABC8, HDVR2X95RS6L, and VWJ33JE6SLED were genuine merch DLC codes that gave Huge Axolotl pets. They were already redeemed by their original buyers and cannot be used again.

Bottom line: if you did not personally buy the merchandise and peel off the scratch-off code yourself, it will not work for you.

Merch Codes — The Only Real PS99 Codes

The one and only legitimate way to get redeemable codes in Pet Simulator 99 is through official BIG Games merchandise. Here is how the system works.

Where to Buy

Head to shop.biggames.io — the official BIG Games merchandise store. They sell:

• Plushies — Stuffed versions of popular PS99 pets
• Mystery Boxes — Blind-box figures with random codes
• Playsets — Larger sets with multiple items and codes
• Lucky Bags — Special bundles with guaranteed exclusives

Each physical product includes a scratch-off tag with a unique single-use code printed underneath.

What Merch Codes Give You

Past merch code rewards have included:

These pets and items are exclusive to merch owners. You cannot obtain them through regular gameplay, hatching, or trading unless someone who already redeemed theirs decides to trade the pet away.

Important Merch Code Rules

• One-time use: Each code works exactly once, on one account
• Desktop only: Code redemption does not work on mobile or tablet (as of Update 4)
• US shipping only: The official store currently ships within the United States
• Age restriction: You must be 13 or older to order (18+ in Texas)
• PS X codes work: Older Pet Simulator X merch codes can also be redeemed in PS99

If you are outside the US, third-party resellers on sites like eBay sometimes sell the codes separately — but buy at your own risk. Scammers are everywhere.

How to Redeem Codes in Pet Simulator 99

Whether you have a merch code or BIG Games drops a surprise public code in the future, here is exactly how to redeem it:

Step 1: Launch Pet Simulator 99 on Roblox from a desktop computer or console.

Step 2: Once you load into the game, look at the bottom of your screen and tap the pet grid button (it looks like a grid of small pet icons).

Step 3: When the pets menu opens, click the Shopping Basket icon (it looks like a small cart). This opens the Exclusive Shop.

Step 4: Scroll all the way down to the very bottom of the Exclusive Shop. You will see a banner with a big green Redeem button.

Step 5: Click the green Redeem button. A text box will appear.

Step 6: Type or paste your code into the text box exactly as shown. Codes are case-sensitive — one wrong letter or capitalization and it will not work.

Step 7: Click the green Redeem button again to confirm.

If the code is valid and has not been used before, your reward will appear in your inventory immediately. If you see an error, double-check your code for typos. If it still does not work, the code has likely already been redeemed by someone else.

Troubleshooting Code Redemption

• “Invalid code” error: The code is either fake, already used, or typed incorrectly
• Cannot find the Redeem button: Make sure you scroll to the absolute bottom of the Exclusive Shop
• Redeem button not responding: Try on desktop — mobile redemption is currently disabled
• Code worked but no reward: Restart the game and check your full pet inventory

Preston’s Super Secret Code

This is hands down the most intriguing mystery in Pet Simulator 99, and it has been driving the community wild since the game launched.

In Area 35, if you look to the left of the main area, you will find a hidden tunnel. Walk through it and you discover a secret shop run by an NPC named Preston (yes, that Preston — the famous YouTuber who collaborates with BIG Games). The shop interface mentions a “Super Secret Code” that supposedly unlocks something incredible.

right now, nobody has cracked this code. The entire PS99 community has tried:

• Brute-forcing common words and phrases
• Searching for clues hidden across every area in the game
• Analyzing game files for encrypted strings
• Testing codes from Preston’s YouTube videos and social media

Nothing has worked. The code remains a mystery.

Every YouTube video with a title like “I FOUND PRESTON’S SECRET CODE IN PS99” is clickbait. Do not waste your time. When (or if) this code is ever discovered, it will be massive news across the entire Roblox community and you will hear about it everywhere.

Our best guess? BIG Games is saving this reveal for a major milestone — possibly a player count achievement, anniversary event, or collaboration. Keep an eye on the BIG Games Discord for official announcements.

How to Get Free Diamonds in Pet Simulator 99

Since free codes are not happening, diamonds are the real key to progression. Here are the most efficient diamond farming strategies we use every day.

Daily Free Diamond Sources

These take almost no effort and should be your first stop every session:

1. Twitter/X Social Verification Follow BIG Games on Twitter/X. In the main plaza, find the social media verification station. Link your X handle and you can claim free diamonds every 5-6 hours. This is essentially free money for following an account.

2. Area 3 Diamond Spot To the right of the Area 3 zone door, there is a diamond collection spot that refreshes every 30 minutes. It gives several hundred diamonds per claim. Hit it every time you walk by.

3. Daily Login Rewards Log in every single day. The daily rewards escalate over consecutive days, with diamond payouts getting significantly better in the second and third week streaks.

4. Minigames Participate in the rotating minigames whenever they appear. The diamond payouts are decent and the time investment is minimal.

Boost Stacking for Maximum Diamonds

This is where the real diamond grinding starts. Stack all of these simultaneously for maximum output:

1. Diamonds Flag — Place one in whatever area you are farming. Gives a flat boost to all diamonds collected.
2. Diamonds Potion — Diamond III gives a 30% boost for 25 minutes. Drink it right before a farming session.
3. Orange Buffs — Eat oranges from the fruit stand. Each one gives +1% diamonds and they stack. Eat as many as you can afford.
4. Fortune Enchant — The single most important enchant for diamond farming. Gives +50% gems from breakables. Put this on every pet you can.
5. Diamonds III Enchant — Additional diamond multiplier on top of Fortune.
6. Magnet Enchant — Quality of life boost that automatically pulls collectibles toward you, reducing wasted time.

When all of these are active at the same time, your diamond income skyrockets. Plan your farming sessions around potion timers to get maximum value.

Smart Diamond Spending Priority

Do not blow diamonds randomly. Invest them in this order for the fastest progression:

1. Pet Slots (Pets Equipped machine) — More active pets means exponentially faster farming
2. Egg Hatch Multipliers (Egg Machine) — Better odds on every hatch pays dividends long-term
3. Fixed Multipliers — Permanent damage and collection boosts
4. Magnet Upgrades — Quality of life that saves real time

Best Diamond Farming Zones

Your zone choice matters. Here is where to farm based on your progression:

• Early game: Area 3 diamond spot + starter zones
• Mid-game: Fantasy World and Tech World offer the best diamond-to-time ratio
• Late game: Volcano areas for superior chest drops
• Free-to-play focus: Fire Dojo (Area 50) offers excellent returns without premium requirements
• World 4 zones: The newest zones with Diamond X enchants and Fortune Flags for endgame players

Best Pets Tier List

Your pet lineup directly determines how fast you progress. Here is the current meta ranked.

S-Tier — Best in Game

These are the endgame pets. Most free-to-play players will not own them directly, but you can work toward them through smart trading.

A-Tier — Strong and Reliable

A-tier pets are realistic targets. Focus your trading here first before chasing S-tier.

B-Tier — Great for Beginners

Pet Management Tips

• You can equip up to 3 active pets at a time (more with pet slot upgrades)
• Quality over quantity — one strong pet outperforms three weak ones
• Match pet elemental types to your farming zone for bonus damage
• Fortune enchant should be your number one priority on every pet
• Focus on Huge-tier pets from recent events — these are the best realistic targets for free-to-play players
• The trading plaza is your most powerful progression tool — game knowledge beats Robux spending every time

Current Trading Values

Values shift constantly with every update, but here are approximate ranges as of:

Always check current values on Traderie or Cosmic Values before making any trades. Overpaying by even a small margin adds up fast.
