I remember the first time I hit the Rebirth button in Build a Base and Steal. I had stacked up a decent base full of pets and a chunk of cash. Hitting that button felt like throwing it all away. Within minutes I was building it all back, but this time with a 2x luck bonus that made every drop feel twice as rewarding. That moment is what this Build a Base and Steal rebirth guide is built around.
If you have been grinding pets and stacking cash without rebirthing, you are leaving permanent upgrades on the table. Rebirthing resets your progress in exchange for bonuses that stack forever. In this guide I walk through every one of the 16 rebirth levels, what each one asks for, what you get back, and the best strategy I have found after dozens of rebirths.
You will find the full requirements list, the complete rewards breakdown, a step-by-step on how to rebirth, and a few strategy tips the community swears by. Let us get into it.

What Is Rebirth in Build a Base and Steal?
Rebirth in Build a Base and Steal is a progression mechanic that resets your money, pets, and base upgrades in exchange for permanent bonuses. Every time you rebirth, you start fresh, but you keep stacking luck boosts, extra pet slots, defense blocks, and gear that make the next run faster and more rewarding than the last.
Think of it as a prestige system. You trade short-term progress for permanent multipliers that affect every future run. The first rebirth only requires 50k in-game money plus a Cat and Chicken. By the sixteenth rebirth, you are trading millions of cash, multiple rare pets, and even Golden pets earned through the pet mutation system.
Here is what you lose when you rebirth: every pet sitting in your base, all your in-game money, and any unlocked base slots above the starting count. Here is what you keep: every reward from previous rebirths, your cosmetics, your account level, and any gear you have purchased from the shop with Robux. The trade-off almost always favors rebirthing sooner rather than later.
All Build a Base and Steal Rebirth Requirements
Below is the complete list of every Build a Base and Steal rebirth requirement from Rebirth 1 through Rebirth 16. Each level asks for a specific cash amount plus a set of pets you must own at the moment of rebirth. The pet list grows longer as you climb, and starting at Rebirth 13 you will need Golden mutated pets.
| Rebirth | Money Required | Pets Required |
|---|---|---|
| Rebirth 1 | 50k | Cat, Chicken |
| Rebirth 2 | 250k | Dog, Cat, Chicken |
| Rebirth 3 | 750k | Bunny, Dog, Cat, Chicken |
| Rebirth 4 | 2M | Deer, Bunny, Dog, Cat, Chicken |
| Rebirth 5 | 5M | Fox, Deer, Bunny, Dog, Cat, Chicken |
| Rebirth 6 | 10M | Bear, Fox, Deer, Bunny, Dog, Cat |
| Rebirth 7 | 25M | Wolf, Bear, Fox, Deer, Bunny, Dog |
| Rebirth 8 | 50M | Tiger, Wolf, Bear, Fox, Deer, Bunny |
| Rebirth 9 | 100M | Dragon, Tiger, Wolf, Bear, Fox, Deer |
| Rebirth 10 | 250M | Raccoon, Dragon, Tiger, Wolf, Bear, Fox |
| Rebirth 11 | 500M | Red Fox, Raccoon, Dragon, Tiger, Wolf, Bear |
| Rebirth 12 | 1B | Phoenix, Red Fox, Raccoon, Dragon, Tiger, Wolf |
| Rebirth 13 | 2B | Golden Phoenix, Phoenix, Red Fox, Raccoon, Dragon, Tiger |
| Rebirth 14 | 5B | Golden Dragon, Golden Phoenix, Phoenix, Red Fox, Raccoon, Dragon |
| Rebirth 15 | 10B | Golden Tiger, Golden Dragon, Golden Phoenix, Phoenix, Red Fox, Raccoon |
| Rebirth 16 | 25B | Golden Phoenix, Golden Dragon, Golden Tiger, Golden Wolf, Phoenix, Red Fox |
Notice how the money requirements scale aggressively after Rebirth 10. Going from 250M to 25B is a hundred-fold jump. The pet list also shifts from common creatures to Golden mutated versions starting at Rebirth 13. That is intentional. The game forces you to engage with the pet mutation system and farm events to push past the mid-game wall.
Across all 16 rebirths you will need 29 unique pets if you count the Golden variants. That is a lot of farming, and it is the main reason most players stall around Rebirth 8 or 9 without a focused strategy.
Rebirth Rewards List
Now for the fun part. Every rebirth hands out a bundle of permanent rewards. The Build a Base and Steal rebirth rewards fall into five categories: luck bonuses that double your chance at rare drops, one-time cash prizes, extra max pets, defense blocks that protect your base from raids, and gear that gives you an edge during steals. Here is the full list.
| Rebirth | Luck Bonus | Cash Bonus | Max Pets | Defense Blocks | Gear |
|---|---|---|---|---|---|
| 1 | 2x | +5k | +2 | +3 | Steel Bat, Speed Coil |
| 2 | 2x | +10k | +2 | +3 | Iron Bat, Speed Coil |
| 3 | 2x | +50k | +2 | +3 | Speed Coil, Jump Potion |
| 4 | 2x | +250k | +2 | +3 | Steel Bat, Speed Coil |
| 5 | 2x | +1M | +3 | +4 | Iron Bat, Speed Coil, Magnet |
| 6 | 2x | +5M | +3 | +4 | Speed Coil, Jump Potion, Magnet |
| 7 | 2x | +10M | +3 | +4 | Steel Bat, Speed Coil, Magnet |
| 8 | 2x | +25M | +4 | +5 | Iron Bat, Speed Coil, Jump Potion |
| 9 | 2x | +100M | +4 | +5 | Speed Coil, Magnet, Jump Potion |
| 10 | 2x | +250M | +5 | +5 | Steel Bat, Speed Coil, Magnet, Jump Potion |
| 11 | 2x | +500M | +5 | +6 | Iron Bat, Speed Coil, Magnet |
| 12 | 2x | +1B | +6 | +6 | Speed Coil, Jump Potion, Magnet |
| 13 | 2x | +2B | +6 | +7 | Steel Bat, Speed Coil, Magnet, Jump Potion |
| 14 | 2x | +5B | +7 | +7 | Iron Bat, Speed Coil, Jump Potion |
| 15 | 2x | +10B | +7 | +8 | Speed Coil, Magnet, Jump Potion |
| 16 | 2x | +25B | +8 | +8 | Steel Bat, Iron Bat, Speed Coil, Magnet, Jump Potion |
After all 16 rebirths you walk away with a permanent 32x luck multiplier from stacking 2x per rebirth, 169B in lifetime cash bonuses, 67 extra max pets, 77 extra defense blocks, and a full gear loadout. That is the Build a Base and Steal max rebirth reward ceiling, and it is what every player is grinding toward.
One thing I want to highlight: the +2 Max Pets bonus early on is what lets you actually hit the pet count for Rebirth 5 and beyond. Without those extra slots you physically cannot hold the pets you need to rebirth. The same applies to defense blocks. More blocks mean less likely raids wipes your base between rebirths.
How to Rebirth in Build a Base and Steal
Rebirthing is a one-button process, but doing it at the wrong time can hurt your progress. Here is the exact step-by-step I follow every time.
Step 1: Reach the money requirement. Open your base and check the cash counter. You need the exact amount listed for your target rebirth sitting in your wallet, not in pets or upgrades. The Rebirth UI tells you exactly how much you have versus how much you need.
Step 2: Confirm you have every required pet. Walk through each pet slot and verify the right creatures are in your base. If you are short one pet, the rebirth will be blocked. Pets walking to your base mid-rebirth do not count, so wait until every slot is filled and stable.
Step 3: Move any pets you want to keep to a backup. This is critical. Pets in your base at the moment of rebirth are deleted. If you have a Legendary or Secret pet you cannot bear to lose, transfer it to an alt account first. I will cover this strategy in the next section.
Step 4: Click the Rebirth button. The Rebirth button lives on the left side of the screen. Press it once to open the confirmation menu. Read the rewards one more time so you know what you are gaining, then confirm.
Step 5: Watch your rewards drop. The luck bonus, cash bonus, extra pet slots, defense blocks, and gear all apply immediately. Your base clears, your money resets to zero, and you start the climb toward the next rebirth.
The whole process takes about 10 seconds. The grind to meet the requirements is what takes hours or days, depending on where you are in the rebirth ladder.
Rebirth Strategy and Preparation Tips
Timing and preparation are the difference between an efficient rebirth ladder and a frustrating one. Here are the strategies I have picked up from the community and from grinding rebirths myself.
Rebirth as soon as you hit the requirements. Holding off does not give you a bonus. If you have the money and the pets, rebirth now. The 2x luck bonus from your next rebirth will speed up the climb to the level after that far more than hoarding pets for a few extra hours ever will.
Hit Rebirth 2 and Rebirth 10 early. These two thresholds unlock extra base floors, which dramatically increase your income per second. Rebirth 2 is essentially free, and Rebirth 10 unlocks the second-floor bonuses that pay for themselves within a single farming session.
Back up rare pets to an alt account. The biggest pain point in the community is losing Legendary and Secret pets during rebirth. Players who run a secondary account can transfer pets over right before rebirthing, then trade them back after. If you do not have an alt account, at minimum let other players steal your rarest pets before rebirth so they do not disappear.
Farm events for rebirth pets. Several limited-time events drop the rare pets required for Rebirths 9 through 12. Red Carpet events in particular spawn high-tier pets at a faster rate. Running a private server during these events lets you control spawns and stock up without competition.
Understand the Golden pet requirement. Rebirths 13 through 16 require Golden mutated pets, which only drop through the pet mutation system. If you have not started chasing Golden pets, you will hit a hard wall around Rebirth 12. Start farming mutations as soon as you clear Rebirth 10.
Use defense blocks wisely. Extra defense blocks only help if you place them around your strongest pets. Spread them out across the base rather than clustering them in one corner. A balanced defense prevents total wipeouts when a raid hits.
Do not rebirth during a steal in progress. If another player is mid-raid on your base, wait for them to finish or fail before clicking Rebirth. Pets in transit during rebirth can cause glitches, and you risk losing the rewards from a successful defense.
These tips will save you dozens of hours over the course of climbing to Rebirth 16. The grind is real, but with the right strategy it is much shorter than going in blind.
What do you need for rebirth in Build a Base and Steal?
You need a specific amount of in-game cash plus a set list of pets sitting in your base. The requirements scale with each rebirth. Rebirth 1 only needs 50k cash, a Cat, and a Chicken. By Rebirth 16 you need 25B cash plus multiple rare pets including Golden mutated versions of Phoenix, Dragon, Tiger, and Wolf.
How much money do you need for the 16th rebirth in Build a Base and Steal?
The 16th rebirth requires 25B in-game cash plus six pets: Golden Phoenix, Golden Dragon, Golden Tiger, Golden Wolf, Phoenix, and Red Fox. You also need to have completed Rebirth 15 first to unlock it.
What are the requirements for Rebirth 7 in Build a Base and Steal?
Rebirth 7 requires 25M in-game cash and six pets: Wolf, Bear, Fox, Deer, Bunny, and Dog. All six pets must be sitting in your base at the moment you click the Rebirth button. The reward is a 2x luck bonus, 10M cash bonus, 3 extra max pets, 4 extra defense blocks, plus Steel Bat, Speed Coil, and Magnet gear.
What are the requirements for the 14th rebirth in Build a Base and Steal?
Rebirth 14 requires 5B cash plus Golden Dragon, Golden Phoenix, Phoenix, Red Fox, Raccoon, and Dragon. You need both Golden and base versions of the high-tier pets. The reward includes a 2x luck bonus, 5B cash bonus, 7 extra max pets, 7 extra defense blocks, and Iron Bat, Speed Coil, and Jump Potion gear.
Is rebirth worth it in Build a Base and Steal?
Yes, rebirth is worth it for any player who wants to progress efficiently. Each rebirth stacks a permanent 2x luck bonus, increases your max pet slots, adds defense blocks, and pays out a one-time cash bonus. The trade-off of resetting your base is more than offset by the permanent upgrades, especially once you hit Rebirth 5 and beyond where the luck bonus noticeably improves rare pet drop rates.
Final Thoughts on Build a Base and Steal Rebirth
The Build a Base and Steal rebirth system is what turns a casual base builder into a long-term grind. Every reset feels painful for about ten minutes, then the new luck bonus kicks in and you realize you are earning twice as fast as before. That compounding loop is what makes reaching Rebirth 16 feel genuinely rewarding.
If you are just starting out, focus on hitting Rebirth 2 and Rebirth 10 as fast as possible. Those two thresholds unlock the base floors that make every future rebirth easier. Once you clear Rebirth 10, shift your attention to the pet mutation system so you have Golden pets ready when Rebirth 13 unlocks.
Use this guide as your reference whenever you are about to push for the next level. Check the requirements, verify your pets, back up anything you cannot bear to lose, and hit that button. The permanent bonuses are waiting on the other side.
