Build a Zoo codes for September 2025

Build a Zoo is a Roblox tycoon game inspired by Grow a Garden (and its many clones). In Build a Zoo, you’ll hunt for rare eggs on a conveyor belt, wait for them to hatch into adorable blocky creatures, and then let them hang out in your zoo and earn you some cash for more eggs.

You’ll earn plenty of cash and new eggs as you play, but if you’re in a hurry, you can use Build a Zoo codes for some rare eggs and plenty of cash, which can be especially useful early on in the game. Development team Century Farmers usually shares new codes in Build a Zoo’s official Discord server, but we’ve done all the hard work for you by rounding up all the current and expired codes as well as instructions on how to redeem codes in Build a Zoo to save you some valuable egg-hatching time.
