Looking for the latest Build a Zoo codes to jumpstart your zoo empire? You’ve landed in the right place! I’ve been playing Build a Zoo since it launched, and I know exactly how valuable these codes are for getting rare eggs, coins, and exclusive pets without spending hours grinding.
In this comprehensive guide, I’ll share every working code for October 2025, show you exactly how to redeem them, and give you insider tips to build the most impressive zoo on your server. Whether you’re just starting out or already have a thriving animal collection, these codes will give you a significant advantage.
Let me cut straight to what you came here for the active codes that actually work right now. I’ve personally verified each of these codes, and I update this list multiple times per week to ensure you’re always getting accurate information.

Pro Tip: Always redeem codes as soon as you see them! Build a Zoo developers release codes frequently, but they also expire them without warning. Some codes like CE8CWQDFZSH have limited redemptions (only 50,000 uses), so speed matters.
Not all codes are created equal. Here’s what each reward type means for your zoo:
Hyper Eggs: These are among the rarest eggs in the game. When hatched, they can give you legendary tier animals that generate significantly more coins per hour. The pets from Hyper Eggs can earn you anywhere from 5,000 to 50,000 coins depending on their rarity mutation.
Prismatic Eggs: These special eggs have a rainbow sheen and contain high value pets. I’ve hatched several Prismatic Eggs and consistently gotten Epic and Legendary pets that help accelerate my coin generation massively.
Tickets: The newest currency introduced in recent updates. Tickets can be used in the premium shop for exclusive items, limited edition eggs, and cosmetic upgrades for your zoo that aren’t available anywhere else.
Coins: The fundamental currency. You need coins for everything buying new eggs from the conveyor, expanding your zoo plots, upgrading your collection capacity, and purchasing special items from the shop.
I keep track of expired codes so you don’t waste time trying codes that no longer work. Here are the codes that have been deactivated:
| Code | Previous Rewards | Expired Date |
|---|---|---|
| BugFix829 | Pet and Rewards | September 2025 |
| SurpriseGift | Pet and Rewards | September 2025 |
| UPD18DINO | Pet and Rewards | September 2025 |
Redeeming codes in Build a Zoo is straightforward, but there’s a catch you must complete the tutorial first. Don’t worry, it only takes about 2-3 minutes. Once you’ve finished that, follow my step by step guide below.
Step 1: Launch the Game Open Roblox and search for “Build a Zoo” or use this direct link to the official game. Make sure you’re playing the correct version by Century Farmers there are copycat games, so double check the developer name.
Step 2: Complete the Tutorial If this is your first time playing, you’ll need to go through a quick tutorial. The game will guide you through:
This tutorial is mandatory and unlocks the code redemption feature. You cannot skip it, so just follow along it’s actually helpful for understanding the game mechanics.
Step 3: Open the Shop Menu Look at the left side of your screen. You’ll see several circular buttons. Click on the Shop button it has a shopping cart icon and is usually the second or third button from the top.
Step 4: Locate the Code Redemption Section Once the Shop menu opens, scroll down. You’ll pass through several sections showing eggs for purchase, premium items, and special deals. Keep scrolling until you reach the bottom where you’ll find a section titled “Enter Code” or “Redemption Code”.
Step 5: Enter the Code Click inside the text box. Here’s where you need to be careful Build a Zoo codes are case sensitive! I recommend copying the code directly from my list above rather than typing it manually. This eliminates any chance of typos.
Important: The codes use a mix of uppercase letters, lowercase letters, and numbers. For example, CE8CWQDFZSH must be entered exactly as shown. Even one wrong character will cause the code to fail.
Step 6: Click Redeem After entering the code, click the Redeem button. If the code is valid and hasn’t expired, you’ll immediately see a notification pop up showing what rewards you received. The items will be automatically added to your inventory.
Step 7: Check Your Rewards Your coins will be added to your balance automatically. If you received eggs, check your inventory by clicking the backpack icon. The eggs will be there waiting for you to place them in your zoo.
“Code Invalid” Error: This usually means the code has expired or you’ve already used it. Each code can only be redeemed once per account. Double check my active codes list above for the latest working codes.
“Code Not Found” Error: You’ve likely made a typing error. Remember, codes are case sensitive. Try copying and pasting the code instead of typing it manually.
Code Box Not Appearing: You probably haven’t completed the tutorial yet. The redemption feature unlocks after you finish the initial tutorial sequence.
Limited Usage Codes: Some codes like CE8CWQDFZSH have a maximum number of redemptions across all players (50,000 uses). If you see “Code Limit Reached,” unfortunately, you missed this one. This is why I always tell people to redeem codes immediately when they see them.
Build a Zoo is a Roblox pet collection simulator developed by Century Farmers that launched in early 2025. Unlike many generic “grow a farm” games, Build a Zoo focuses specifically on creating and managing a zoo filled with exotic animals, mythical creatures, and even fantasy beasts.
The gameplay loop is satisfying and addictive. Here’s how it works:
The Conveyor System: At the center of your zoo is a conveyor belt that continuously produces eggs. These eggs vary in rarity from Common (white) to Legendary (rainbow with special effects). You purchase eggs from the conveyor using coins, and the conveyor can be upgraded to offer rarer egg types.
Hatching and Collection: Once you buy an egg, you place it on one of your plots. After a brief incubation period (usually 5-15 seconds depending on rarity), the egg hatches into an animal. These animals generate coins passively over time. You can either collect coins by clicking on them or let them accumulate automatically if you have the idle collection feature unlocked.
Zoo Expansion: You start with just a few plots, but as you progress, you can purchase additional plots to expand your zoo. Each plot costs coins, and the price increases with each purchase. A fully expanded zoo can house 50+ animals simultaneously.
Rarity Tiers: Animals come in different rarity tiers that affect their coin generation:
Mutations and Special Variants: Some animals hatch with mutations special visual effects or stat bonuses that increase their value. For example, a Shiny Lion might generate 2x the coins of a regular Lion. Elemental variants (Fire, Ice, Electric) also exist and are highly sought after.
Build a Zoo receives frequent updates, and staying current with changes is crucial. Here’s what’s new in October 2025:
Update 25 (October 2025): The developers teased a major update coming in October that will introduce new seasonal content, limited edition eggs, and potentially a trading system. While full details haven’t been released, the community is buzzing with excitement.
Season One Content: The game recently introduced seasonal content with exclusive pets and eggs only available during specific time periods. The Season One theme focused on aquatic animals and introduced the popular Lionfish egg available through the ZooFish829 code.
Big Pet Update: Recent patches added “Big Pets” massive versions of existing animals that take up multiple plots but generate significantly more coins. These are obtained through special Rainbow Eggs and limited time events.
Fishing System: A fishing minigame was added that lets you catch fish pets to add to your collection. This provides an alternative progression path beyond just buying eggs from the conveyor.
Album Collection System: New collection tasks in the Album feature give you goals to work towards. Completing albums rewards you with exclusive pets, coins, and cosmetic items.
After spending hundreds of hours in Build a Zoo, I’ve developed strategies that helped me build one of the top zoos on my server. Let me share these insider tips with you.
Not all eggs are worth your coins. Here’s my priority system:
Early Game (0-100k coins): Focus on Prismatic Eggs and Hyper Eggs from codes. Don’t waste coins on the conveyor yet use your free code eggs to build a foundation. Each Prismatic or Hyper Egg pet will generate enough coins to buy multiple Common eggs from the conveyor later.
Mid Game (100k-1M coins): Start selectively buying from the conveyor, but only when you see Epic or higher rarity eggs. The conveyor cycles through different eggs, so patience pays off. I typically wait for the purple or gold glow before purchasing.
Late Game (1M+ coins): At this stage, focus on Mutated Eggs, Fire Eggs, and Electric Eggs. These special variant eggs consistently produce the highest value animals. A single Fire Dragon can generate more coins per hour than 20 Common pets combined.
Managing your zoo plots efficiently is crucial for maximizing coin generation:
The 80/20 Rule: Keep 80% of your plots filled with your highest earning animals and use 20% for hatching new eggs to potentially find better pets. This ensures consistent income while still allowing room for upgrades.
Pet Rotation Strategy: When you hatch a new animal, compare its coin generation to your lowest earning current pet. If the new pet earns more, sell the old pet and replace it. This constant optimization compounds over time.
Plot Expansion Timing: Don’t rush to buy all plots immediately. Expand your plots only when you have animals ready to fill them. An empty plot is wasted potential coins that could have been invested elsewhere.
The conveyor belt can be upgraded to increase the quality of eggs it produces. Here’s the optimal upgrade sequence:
Upgrade 1 (50k coins): Increases the chance of Uncommon eggs appearing Upgrade 2 (250k coins): Adds Rare eggs to the rotation Upgrade 3 (1M coins): Adds Epic eggs to the rotation Upgrade 4 (5M coins): Adds Legendary eggs to the rotation Upgrade 5 (25M coins): Adds Mythical eggs and Rainbow variants
I recommend saving for Upgrade 2 before anything else. The jump in egg quality from Uncommon to Rare provides the best return on investment.
While trading isn’t officially implemented yet, dataminers have found code suggesting it’s coming in Update 25. When trading launches, here’s my planned approach:
Focus on collecting duplicates of high demand pets (Fire Dragons, Electric Lions, Shiny variants) to trade for pets you’re missing from your collection. Pets with visual effects will likely have the highest trade value.
Codes are released irregularly, but there are several reliable sources where they appear first:
Build a Zoo Discord Server: The official Discord (https://discord.com/invite/6J4Upm2qKk) has a dedicated codes channel where developers post new codes immediately upon release. Join the server and enable notifications for the #codes channel to get instant alerts.
Century Farmers Roblox Group: Join the Century Farmers group on Roblox. Members sometimes receive exclusive codes not available anywhere else. Additionally, group members get access to special in game rewards like free rare pets just for being a member.
Game Updates and Milestones: Developers frequently release codes when the game hits milestones. For example, when Build a Zoo reached 100 million visits, they released multiple codes. Follow their social media to catch these announcements.
Roblox Game Page: Sometimes codes are hidden in the game description or update logs on the official Roblox game page. I check this every time there’s an update.
I personally update this guide at least 3-4 times per week, often more during major updates. I’m active in the Build a Zoo Discord, so I typically add new codes within hours of their release. Bookmark this page and check back regularly I’ve got your back!
Let me share some advanced techniques that most players don’t know about:
Even though Build a Zoo requires you to click animals to collect coins, there’s an idle collection mechanic that many players miss. If you join the Century Farmers Roblox group and verify in game, you unlock passive coin collection that automatically gathers coins from your animals every 5 minutes, even when you’re offline.
To activate this:
This feature alone can double or triple your coin generation over time, especially if you play casually and aren’t online constantly clicking animals.
Here’s a technique I discovered that maximizes your egg investment: Don’t hatch all your eggs immediately. Instead, buy multiple high quality eggs (Epic or Legendary) when they appear on the conveyor, then hatch them all at once.
Why does this work? When you hatch multiple rare eggs simultaneously, you increase your chances of getting at least one exceptional pet with good mutations or special effects. It’s essentially batch processing your RNG luck instead of being disappointed one egg at a time.
Through extensive testing and community data analysis, these are the top performing pets by tier:
Legendary Tier:
Epic Tier:
Special Variants:
Selling pets is sometimes necessary, but do it strategically:
Never Sell: Legendary and Mythical pets unless you have duplicates Always Sell: Common pets once you have better options in every plot Consider Selling: Epic and below if you need quick coins for a major upgrade
The selling price is typically 50% of a pet’s total value, so you lose money on every sale. Only sell when the immediate coin injection will help you make a significant upgrade that will pay back the lost value quickly.
Understanding the update schedule helps you plan your gameplay and know when to expect new codes.
Century Farmers releases updates approximately every 2-3 weeks. These updates usually include:
Major content updates arrive monthly and bring:
Based on developer teasers and community speculation, Update 25 will likely feature:
Trading System: Player to player pet trading has been the most requested feature. Code snippets found in the game files suggest this is nearly ready.
Seasonal Battle Pass: A progression system with free and premium tiers offering exclusive rewards as you play. This is standard in most popular Roblox games now.
New Mythical Pets: At least 3-5 new Mythical tier animals, including rumored Halloween themed creatures since October is typically when spooky content releases.
Zoo Customization: Ability to customize your zoo’s appearance with decorations, themes, and special effects.
Guild System: Team up with other players to complete group challenges for better rewards.
Build a Zoo stands out in the crowded Roblox simulator space. Here’s how it compares:
Grow a Garden focuses on plant collection while Build a Zoo centers on animals. Grow a Garden has more complex breeding mechanics, while Build a Zoo emphasizes straightforward collection and progression. Both games share similar code redemption systems and update frequencies.
Pet Simulator X has been around longer and has more content, but Build a Zoo offers a more focused experience. PSX can feel overwhelming with hundreds of pets, while Build a Zoo’s curated selection makes collection goals more achievable. Build a Zoo also has better graphics and performance optimization.
Unlike Animal Crossing clones on Roblox, Build a Zoo doesn’t focus on social features or island decoration. It’s purely about pet collection and income generation, which appeals to players who prefer min maxing and optimization over creative building.
The Build a Zoo community is active and helpful. Here are the best places to connect with other players:
The Build a Zoo Discord (https://discord.com/invite/6J4Upm2qKk) has over 111,000 members and includes:
While there isn’t an official Build a Zoo subreddit yet, discussions happen in r/roblox and r/RobloxSimulators. The community shares tips, trading guides, and code findings.
Several YouTubers create Build a Zoo content:
Following these creators gives you another avenue for finding new codes quickly.
No, Build a Zoo codes only provide in game items like eggs, coins, pets, and tickets. No legitimate Roblox game can give away Robux through codes anyone claiming otherwise is running a scam. Robux can only be obtained through official Roblox purchases or the Premium subscription.
Code expiration varies significantly. Some codes last for weeks, while limited use codes (like CE8CWQDFZSH with only 50,000 redemptions) can expire within days if the game is popular. I recommend redeeming all codes immediately when you see them to avoid missing out.
Yes! Build a Zoo codes are limited to one redemption per account, not per player. If you have multiple Roblox accounts, you can redeem the same code on each account. This is useful if you want to test different strategies or play with friends.
Based on my testing and community data, Mutated Eggs consistently produce the highest value pets. If you can’t find Mutated Eggs, Fire Eggs and Electric Eggs are your next best options. These special variant eggs have significantly better pets than standard eggs of the same rarity tier.
Unfortunately, no. The developers haven’t created an official Trello board or Wiki yet, which is unusual for popular Roblox games. Players have requested this feature extensively, but there’s no timeline for when (or if) it will be added. For now, the Discord server and community guides (like this one) are your best information sources.
There are several common reasons:
Absolutely not! Codes are officially released by the developers and are intended to be used by all players. Using codes is completely safe and won’t result in any penalties. However, using exploits, hacks, or third party programs can get you banned stick to legitimate codes only.
Yes! Build a Zoo codes work identically on all platforms PC, mobile (iOS and Android), Xbox, and any device that runs Roblox. The redemption process is the same regardless of your platform.
Currently, the rarest pet is the Galaxy Dragon, a Mythical tier animal with special particle effects. It’s extremely difficult to obtain and requires either exceptional luck with Rainbow Eggs or completing specific collection achievements. Only a small percentage of players have successfully hatched one.
While some players claim “secret codes” exist, these are usually just regular codes that haven’t been widely shared yet. The developers don’t typically create true secret codes. All codes are eventually posted on the official Discord, so your best bet is monitoring that channel for new releases.
Egg prices vary based on rarity:
Special variant eggs (Fire, Electric, Mutated) typically cost 2-3x the standard price for their rarity tier.
Not yet, but trading is expected to be added in Update 25 (October 2025). When trading launches, you’ll likely need to reach a certain level or play time requirement before unlocking the feature to prevent exploitation.
Build a Zoo has quickly become one of my favorite Roblox simulators, and for good reason. The combination of straightforward gameplay, gorgeous visuals, and frequent updates creates an addictive experience that respects your time while still offering depth for dedicated players.
The codes I’ve shared above will give you a significant head start, but remember that Build a Zoo rewards consistency. Logging in daily, strategically managing your zoo, and staying updated with new codes (by bookmarking this page!) will help you build an impressive collection.
