First steps in the lobby

Step

In short Spend a few minutes in the lobby before any match so you enter with working attackers and free rewards already claimed.

When you load into the game, the lobby is where you collect play-time rewards, check daily and weekly quests, and summon units. Reading quest conditions before a match lets you knock out multiple objectives in a single run. Aim to have at least three attack-capable units ready before you start.

Collect rewards open your play-time rewards and grab any cash or crates waiting for you.
Read quests check daily and weekly quest conditions so one match can count toward several at once.
Summon attackers use Basic Summon with cash to fill out your roster with at least three units that can actually attack.
Hold off on farmers add farm-type units only after your attack lineup is solid.
Save gems gems are also spent at the Merchant, so do not blow them all on Premium Summons right away.

Summons, crafting, and duplicates

Table

In short Match the currency to the right system and never throw away duplicate units before checking the crafting recipes.

There are two summon types and two ways to build your roster. Basic Summon costs cash and is your main tool for getting early attackers. Premium Summon costs gems and targets rarer units. The Merchant also accepts gems in exchange for materials or special units, so plan before you spend. The Craft station lets you pick a recipe and produce a specific unit, and duplicate low-rarity units can serve as crafting materials.

Basic Summon	spends cash, best used to quickly build an early attack lineup.
Premium Summon	spends gems, aimed at pulling higher-rarity units.
Merchant	spends gems for materials or special units outside the summon pool.
Craft station	uses a chosen recipe to produce a targeted unit rather than a random one.
Duplicate units	check crafting recipes before selling or discarding any extras.

Choosing your first map and difficulty

Check

In short Start on Base with Normal difficulty until ten-wave clears feel comfortable, then raise only one variable at a time.

Base on Normal is the right starting point. It runs ten waves. Once that feels routine, move up in only one direction — harder difficulty on the same map, or the same difficulty on a new map, never both at once.

Pick the Base map from Brainrot Bases for your first match.
Set difficulty to Normal.
Clear all ten waves without losing before moving on.
Raise either the map or the difficulty, not both at the same time.

Playing through the ten waves

Step

In short Place cheap attackers at the entrance first, add a farmer only after the first few waves are comfortable, then shift all investment to combat units before the final wave.

Open with attackers near the entrance, earn some stability, then layer in economy and upgrades. Stop spending on new farmers entirely before the last wave and put that cash into your fighters.

Wave 1 setup place two cheap attackers near the entrance to handle the first enemies safely.
Waves 1–3 stable if enemies are dying well before your base, add one farmer unit to a spot off the path.
Mid-game focus upgrade your best attacker rather than placing more weak units.
Group threat if a cluster of enemies slips through, upgrade your area-damage unit first.
Single tough enemy if a high-health enemy is surviving, move investment to your single-target unit.
Final wave prep stop building new farmers and put all remaining cash into combat upgrades.

Placing units effectively

Tips

In short Corners and switchbacks give your units the most attack time, so treat them as top-priority placement spots.

When you select a unit before placing it, the game shows a circle representing its attack range and highlights the enemy path in red. You want that circle to overlap the path for as long as possible, not just clip it.

Tips worth knowing

Choose spots where the range circle covers a long stretch of the enemy path, not just a brief crossing.
Corners and switchbacks in the path are the highest-value placement spots because enemies spend more time inside your range there.
Place area-damage units closer to the entrance where groups of enemies are densest.
Place single-target units further along the path where tough, high-health enemies arrive.
Put farmer units on open ground away from the path so they do not block combat unit placement.
Keep at least one defender near your base as a last line in case something slips through.

Diagnosing a losing run

Check

In short Pin down exactly where and how enemies broke through, then change only one thing before you try again.

Change one variable per attempt so you can actually tell what fixed it.

Losing around wave 5 check whether you placed a farmer before your attack lineup was ready.
Groups of weak enemies reaching the base add or upgrade an area-damage unit.
One tough enemy surviving every wave check whether your single-target unit can see that section of the path.
Collapsing in the final waves check whether you stopped upgrading your main attacker mid-game.
Repeated failure at the same wave: change exactly one thing one fewer farmer, one extra attacker, or one more upgrade — so the cause is clear.

Safety and spending habits

Warn

In short Set a limit on gems and Robux before you start playing, and never share personal details in chat.

Summons and crates involve randomness, and some items cost real Robux or gems. Decide on a cap before you play. The chat in any Roblox game is public — keep personal information completely out of it. If another player is causing problems, use the block, report, and server-switch options.

Worth watching out for

Never type your real name, address, school, phone number, or social media contact into chat.

If someone is harassing you, block them, report them, and move to a different server.

Decide how many summons or how much real money you will spend before you open the game, not while you are in it.

Take breaks between matches, especially during long sessions, and watch for your device overheating.

Common questions

FAQ

What map and difficulty should I start with?

Pick Base from Brainrot Bases and set the difficulty to Normal. That combination runs ten waves. Once you can clear it comfortably, raise either the map or the difficulty — not both at the same time.

When should I place my first farmer unit?

Wait until waves one through three are clearly under control before you drop a farmer. In the final waves, stop adding new farmers entirely and put your money into combat upgrades instead.

Can I throw away duplicate units?

Not before checking the crafting recipes. Duplicate low-rarity units can be used as materials at the Craft station to build specific units you actually want. Check what recipes are available first, then decide whether the duplicate is worth keeping.

How many players can join one room?

Up to 20 players can be in the same room.

Where do I enter redeem codes?

There is a code input field inside the game. Codes can expire or have a limited number of uses. The game's community server is where new codes are announced.
