Build a Base and Steal runs on a tight loop. You roll for pets that generate cash, stack that cash into upgrades, then raid other players to grab their best earners before they raid you back. Everything happens on small six-player servers, so every steal and every defensive choice lands on someone specific.
Quick answer: Roll pets for free at the Egg Mystery station on your base, keep your rarest pets to build passive income, spend that income on Pet Luck and stronger blocks, and steal higher-tier pets from rivals using a bat while defending your own with tall, layered, maze-like walls.
Roll pets at the Egg Mystery station
Pets are the engine of the whole game, and they all come from your home base. Climb the platform and press the red button in front of the Egg Mystery hologram to spin for one.
Rolling itself is free. When the hologram stops on an animal, whether you actually get it depends on how much cash you have on hand. The rarer the pet, the more money it produces once it is placed in your base, so the goal is to keep landing on higher tiers.
That is where the Pet Luck Multiplier comes in. Investing cash into it raises your odds of hitting good pulls, which matters far more over time than a single lucky spin. Early on, roll to see what you have, mark which pets are worth defending, then start funneling money toward luck instead of spamming low-tier rolls.
How money generates, offline earnings, and rebirth
Money is simple in concept. The more pets you own, the more cash you generate per second. Because both rolling and stealing cost nothing, your income is really a function of how many high-earning pets you can keep alive in your base.
Your pets do not stop earning when you leave. Offline income keeps ticking, so logging back in usually hands you a lump sum. Placement and defense still matter here, since anything left exposed can be stolen while you are away.
Rebirth is the long-term multiplier. Click the Rebirth icon on the left side of the screen and meet the listed requirements to reset. It wipes your progress, which stings, but the pace of the game means you climb back quickly with a permanent boost that makes every future run faster.
Tip: Do not sit on a rebirth you have already earned. The bonus compounds with every cycle, so the sooner you reset once you qualify, the sooner your income curve steepens.
How to steal pets from other bases
Stealing is the fastest way to jump ahead. Instead of grinding rolls for a rare, high-earning pet, you take one that a rival already rolled. It costs no cash, only risk.
On six-player servers, targets are limited and personal, so expect retaliation. Do not leave your own base wide open while you are off raiding someone else’s.
Base defense that holds up to raids
The further you progress, the more often you get invaded, so a strong base is the single most important investment you make. Spend a healthy chunk of currency rolling for blocks. Rare blocks are the hardest to destroy, but a smart layout built from regular blocks can still turn raiders away.
Four layout principles do most of the work:
| Defense | Why it works |
|---|---|
| Double-layered walls | Forces thieves to break through twice, doubling the time you have to catch them. |
| Maze-like interior | Confuses invaders trying to reach the pets stored in the center. |
| Tall structure | Stops raiders from simply jumping in to grab a pet. |
| Traps and weapons | Buy everything available in the shop and booby-trap the approach paths. |
Keep your highest-earning pets deep inside the maze, never near the entrance. The point of the layout is to buy time. If a thief needs long enough to reach the center, you can reach them first and knock them back before they escape with anything.
Codes and confirming the right game
There are no verified active codes right now. If a code page or promo pops up after a major update, that is the moment to check, since redeemable rewards tend to arrive alongside patches rather than between them.
One thing worth double-checking before you sink hours in. Several Roblox experiences share very similar names in this brainrot-tycoon space, so make sure you are loading the game you actually mean to play. You can jump straight to the correct listing on the official Build a Base and Steal Roblox page.
Once you have the loop down, the game rewards balance. Roll and rebirth to keep income climbing, defend the pets that carry your earnings, and pick raids you can actually get away with. Do all three and you climb fast, even after a reset.
