Base defense is the part of Build a Base and Steal that new players struggle with most. The walls look simple, the traps look intuitive, but the actual mechanics are layered, and a base that "looks" defended can be raided in seconds by an experienced attacker. This FAQ covers the most common questions about base defense, with practical answers that will help you stop losing pets to raids.
How Do I Protect My Pets?
Pet protection in Build a Base and Steal is purely structural. Pets generate income regardless of where they are placed, but they can only be stolen by a raider who reaches their physical location in your base. The two defensive layers are walls (which block raider movement) and traps or turrets (which damage or kill raiders). The best bases combine both: walls to slow raiders down, and traps to punish them for taking specific paths.
The third layer is pet storage, which most players do not consider. Pets in your inventory (not in your base) cannot be stolen. The smart play is to keep your most valuable pets in storage most of the time, and only place your mid-tier pets in the base to bait raids. This way, even if a raid succeeds, the attacker walks away with disposable pets rather than your best assets.
Do Walls Stop Raiders Completely?
No. Walls slow raiders down but do not stop them permanently. A raider with a hammer can break through any wall, and a raider with enough time can break through any trap. The goal of defense is not to make your base unraidable; it is to make your base expensive enough to raid that attackers move on to easier targets.
A base with two layers of walls and three traps is significantly harder to raid than a base with one wall and no traps. The cost to the attacker, in both time and gear, is the only thing that matters. If you can make the attacker spend more resources raiding you than they would earn, you win the defense.
How Many Walls Do I Need?
There is no fixed answer, but a reasonable rule of thumb is to have at least twice as many walls as your highest pet count. If you have 10 pets in your base, you want at least 20 walls. The ratio of 2:1 keeps the attacker in your base long enough for trap damage to add up and for backup players (or automated turrets) to engage.
The shape of the walls matters as much as the count. A long single-layer wall is easier to break than a short double-layer wall, because the attacker has to break through the same wall twice. Concentric defenses (walls in nested rings) are stronger than linear defenses (walls in a single line) for the same total wall count.
Where Should I Place Traps?
Traps should be placed at chokepoints, not in open areas. A trap in the middle of a wide floor section is easy to jump over, but a trap in a narrow hallway is unavoidable. The classic chokepoint is a doorway between two walls: the attacker has to walk through the doorway to proceed, and the trap catches them in the bottleneck.
The second-best place for traps is at corners. Raiders tend to slow down at corners while they check for additional threats, which gives trap damage more time to apply. Open floor traps are nearly useless, because most raiders will see them and route around.
What Are Turrets and Are They Worth It?
Turrets are automated defense structures that fire at raiders within a certain range. They cost more than walls or traps but provide constant damage without requiring the attacker to trigger them. A single well-placed turret can make a section of your base effectively unraidable, because the attacker will be shot continuously while they try to break through the wall.
Turrets are worth it once you have a stable income and a base worth defending. New players should not buy turrets; the cost is better spent on walls and traps. Mid-game players should buy one or two turrets and place them at their most critical chokepoints. End-game players typically have four to six turrets arranged in overlapping fire zones, which is enough to repel all but the most organized raids.
What Happens When a Raid Succeeds?
When a raid succeeds, the attacker steals up to three pets from your base. The pets they can steal are the ones physically present in the base, not the ones in your storage. The attacker chooses which pets to take, so they will obviously take your most valuable ones.
There is no warning when a raid is about to succeed. The attacker simply walks into your base, breaks through your walls, picks up your pets, and leaves. The game's raid log shows you which pets were stolen and when, and the stolen pets are gone permanently unless the attacker later puts them up for trade and you can negotiate a return.
Can I Get My Pets Back After a Raid?
Only through trade. Once a pet is stolen, it belongs to the attacker and can be sold, traded, or stored on their account indefinitely. There is no "reclaim" mechanic, and there is no in-game insurance for raided pets. The closest thing to insurance is the Premium Pass pet-protection feature, which reduces the chance of your highest-rarity pets being stolen by 50 percent. It is not a guarantee, but it is the only built-in protection.
The psychological impact of losing a pet to a raid is one of the main design features of the game. The developers want players to feel the loss, because the loss motivates them to invest in better defenses, which in turn makes the game's economy more interesting. Do not rage-quit after a raid; use the loss as motivation to rebuild.
Should I Build a Big Base or a Small Base?
Both work, but for different reasons. A big base is harder to navigate and easier to defend with traps, but it costs more to build and is more obvious to attackers. A small base is cheaper and more discreet, but it is easier to clear out in a single raid. Most experienced players settle on a mid-sized base of 20 to 30 walls, which is enough to create meaningful chokepoints without becoming a target.
The "decoy base" strategy is popular with veteran players. They build a small, lightly defended base that looks valuable, and they keep their real base in a different account or in a private server. When attackers raid the decoy, they walk away with disposable pets, and the real collection remains safe. This strategy is borderline within the game's terms of service, so check the current rules before relying on it.

Additional Strategic Context
Reading further expands on the practical considerations that experienced players apply when using the strategies outlined above for the faq area of faq. The content here is drawn from community testing, observed high-level play patterns, and the documented interactions between faq mechanics and other game systems. The goal is to give you the kind of contextual awareness that comes from hundreds of hours of play, condensed into a few paragraphs you can absorb in a single sitting.
The first thing to understand is that every choice in Build a Base and Steal has opportunity cost. When you spend cash on rolling, you are choosing not to spend it on wall upgrades, trap purchases, or storage expansion. When you place a pet in your outer ring, you are choosing to expose it to raids in exchange for income. When you join an event team, you are choosing to coordinate with strangers instead of playing solo. None of these choices are objectively correct, and the right answer changes as your collection, your base, and the meta evolve.
The second thing is that faq has a feedback loop with the rest of the game. A stronger base leads to more successful defenses, which leads to more retained pets, which leads to higher offline income, which leads to faster progression, which leads to a stronger base. The opposite feedback loop is also true: a weak base leads to lost pets, slower progression, and weaker defenses. The early-game decisions have outsized impact because they determine which loop you enter.
The third thing is that the meta shifts with each patch, and the strategies that worked last month may not be optimal this month. The most resilient players are the ones who build a deep understanding of the underlying mechanics, not the ones who memorize specific pet rankings or wall layouts. When the meta shifts, a player who understands the mechanics can adapt their strategy in a day. A player who memorized the old strategy has to relearn everything.
Common Pitfalls and How to Avoid Them
New players in the faq area of Build a Base and Steal tend to make a predictable set of mistakes, and most of these mistakes are not obvious until you have made them a few times. This section lists the most common pitfalls and explains how to avoid each one.
Pitfall one: rolling without a target. The temptation is to rolling randomly produces random results. The result is that the intended goal is not achieved. The fix is to Pick a target pet or family before you start rolling, and stop when you reach your budget. Random rolling is the slowest path to a strong collection.
Pitfall two: letting storage overflow. The temptation is to pets and items that overflow your storage cap are lost. The result is that the intended goal is not achieved. The fix is to Set up a recycling routine that runs at the end of every session. A clean storage is a useful storage, and the discipline prevents the bloat that traps many players.
Pitfall three: missing event windows. The temptation is to limited-time events offer 5-10x the normal rewards. The result is that the intended goal is not achieved. The fix is to Keep a calendar of upcoming events and plan your rolling and trading budget around them. The events are where the largest single-session gains come from.
Pitfall four: ignoring the trading economy. The temptation is to trades can give you access to pets you cannot easily roll. The result is that the intended goal is not achieved. The fix is to Build a small reserve of tradeable pets and learn to read the market. Even a few successful trades can fund weeks of rolling.
