01

Getting started with rolls and placement

Step
In short Rolling for plants and placing them immediately gets your defenses up before the first enemies arrive.

When a match begins, Brainrot enemies start closing in on your base right away, so you need plants on the field quickly. Use the gacha roll to get your first plants, then set them around your base to intercept incoming attackers.

  1. Roll the gacha to pull a random mutant plant.
  2. Place your plant around your base to attack approaching enemies.
  3. Check your base gauge to see how much damage your base has taken.
  4. Roll again to build up more plants.

Merging plants to grow stronger

Tips
In short Merging identical plants is the core way to power up your defenses.

The merge system turns two plants of the same type into one more powerful version.

Tips worth knowing
  • Combine two identical plants to evolve them into a single, stronger plant.
  • Collect duplicates — rolling the same plant twice lets you merge.
  • Upgrade your base to increase how much punishment it can absorb before the game ends.
03

Surviving the Brainrot waves

Check
In short Balancing plant placement and base upgrades keeps you alive through increasingly tough waves.

Different Brainrot enemies push through different parts of your base area. Upgrading your base itself buys extra time when plants alone are not enough.

  • Watch the damage gauge for each area of your base and reinforce whichever zone is taking the most hits.
  • Upgrade your base to increase how much punishment it can absorb before the game ends.
04

Taking on the World Boss with a team

Tips
In short The World Boss is far stronger than any standard wave enemy and requires multiple players cooperating.

Up to five players can share a room, and the World Boss is far stronger than any standard wave enemy.

Tips worth knowing
  • A team where each player grows different plant types covers more weaknesses than players running identical lineups.
  • Up to five players can participate in the same room for the World Boss challenge.
05

Redeem codes for free rewards

Step
In short Codes are single-use and expire, so enter them as soon as you find them.

The game has a code redemption screen. Each code can only be used once, and some codes stop working after a set period.

  1. Find the code entry screen in the game.
  2. Type the code exactly.
  3. Each code is single-use, so once it is redeemed you will need a fresh one.

FAQ

How many players can join one room?

Up to five players can be in the same room at once.

What happens when my base takes too much damage?

Do codes expire?

Some codes have expiry dates, so you should enter any code you find as soon as possible. Each code can only be redeemed once, meaning you cannot use the same one twice.

What does the Premium bonus do?

Premium status gives you a twenty percent boost to Gmes.
