You've finally hit level 1100. You're standing in the Cold side of the Hot and Cold island in the Second Sea, staring at those four monitors in the secret lab. You want that Fragment grind to start. You want to awaken your fruit. But honestly? Most players just stand there clicking buttons randomly because they forgot the Blox Fruits raid code or they’re looking at an outdated wiki.
It’s annoying.
The code isn't some secret password you type into a chat box. It's a color-based sequence you have to input on the monitors to open the secret door leading to the raid lobby. If you get it wrong, nothing happens. If you get it right, a passage opens up in the wall nearby, leading you to the mysterious invisible ladders that take you to the Scientist NPC.
Getting the Blox Fruits Raid Code Right Every Time
Basically, the sequence is a static pattern. It doesn't change based on your level, your fruit, or the time of day. Some people think it rotates. It doesn't.
To unlock the raid lab, you need to press the buttons under the four monitors in this specific order: Red, Blue, Green, Blue.
That’s it.
You walk up to the monitors in the laboratory—which is located inside the large mechanical structure on the snowy side of the island—and tap them until they show those colors from left to right. Once the screens match that pattern, a door opens on the right side of the room.
Why the Sequence Matters for Your Fragments
Fragments are the lifeblood of the mid-to-late game. You can't just rely on Sea Beast hunting or random chests if you want to fully awaken something like Dough or Phoenix. You need thousands of them. Raids are the most efficient way to get them, but you can't even start a raid without getting past those monitors first.
Once you’re through that door, you’ll find the Mysterious Scientist. He’s the guy who sells you the Raid Chips. You need a chip to actually start the process. You can buy one every two hours for 100,000 Beli, or you can trade any physical fruit to him if you don't want to wait for the cooldown.
Most people just buy them. Beli is easy to come by; time isn't.
The Most Common Mistakes Players Make in the Lab
I’ve seen people spend ten minutes jumping around the lab because they think the door is glitched. Usually, it’s one of three things.
First, they’re hitting the buttons too fast. The game’s hit registration can be a bit wonky, especially if you’re playing on a high-ping server. You click red, it stays black, you click again, and suddenly it’s blue. Slow down. Make sure the color actually registers on the screen before moving to the next one.
Second, they’re in the wrong place. The Blox Fruits raid code only works on the monitors in the Second Sea (Hot and Cold). If you’re in the Third Sea looking for a keypad in the Sea of Treats, you’re in for a bad time. In the Third Sea, the raid access is handled differently, primarily through the secret area in the Castle on the Sea or the specialized NPC for the Dough raid.
Third, and this is the big one: they forget you actually have to be level 1100 to host a raid. You can join a raid at any level if someone else starts it, but if you want to be the one punching in the code and buying the chip, you’ve gotta have the levels. If you aren't 1100, the scientist basically tells you to get lost.
Decoding the Color Pattern Logic
There isn’t a deep lore reason for Red-Blue-Green-Blue, but it has become a bit of a rite of passage. It's the moment the game shifts from "click bandits for hours" to "coordinate with a team or get wrecked."
Raids are hard.

If you’re going in solo because you just unlocked the door, you’re probably going to lose. The NPCs in raids have massive health pools and can stun-lock you into oblivion. Most seasoned players recommend having at least one person with a fully awakened Buddha fruit to act as a "tank" while the others deal damage. If you don't have a Buddha on the team, the final island boss will likely one-shot you before you can even get your transformation off.
Advanced Tips for Raid Success
Once you use the Blox Fruits raid code and get upstairs, don't just jump into the tubes. Check your inventory. Do you have a decent fruit equipped? Are your stats distributed correctly?
If you have 500 points in everything, you’re going to struggle. Raids require specialized builds. Most players go full "Glass Cannon" with max stats in Melee, Defense, and either Blox Fruit or Sword.
- Bring a healer: If you have someone with the Phoenix or Love fruit, keep them in the back.
- Time management: You have a 10-minute timer. If you spend too much time on the first four islands, you won't have enough left to kill the boss.
- Fragment yield: The faster you finish, the more Fragments you get. A perfect run usually nets you around 1,000 Fragments. If you finish with only a few seconds left, you might only get 300-500.
It’s also worth mentioning that some raids are "Advanced Raids." You can't just walk up and start a Dough raid. You have to unlock it by defeating the Dough King and getting a Red Spikey Coat or a Sweet Chalice to craft a Cake Scientist's invitation. The standard Red-Blue-Green-Blue code gets you into the basic raids (Flame, Ice, Quake, Light, etc.), but the endgame stuff requires extra steps.
What Happens if the Code Doesn't Work?
If you've entered Red-Blue-Green-Blue and the wall hasn't moved, look at the floor. Sometimes a tiny pixel of an NPC or a stray projectile from a fight outside can interfere with the "zone" trigger. Reset your character or change servers. Usually, a fresh server fixes any interaction glitches with the monitors.
Also, make sure you aren't trying to enter the code while in combat. If you have the "Combat Tag" active, the game sometimes restricts environmental interactions to prevent people from "clipping" out of fights.
Moving Past the Lab
The Blox Fruits raid code is really just the beginning of the "real" game. Once you start farming raids, the power scaling of your character goes through the roof. An awakened Light fruit or Magma fruit is significantly better for grinding than their unawakened versions.

Don't stay in the Second Sea longer than you have to. Once you hit level 1500, the Third Sea opens up, and that's where the real gear—like the Cursed Dual Katana or the Soul Guitar—resides. But you'll always need to come back to these raids to stock up on Fragments for stat resets and race rerolls.
Keep a screenshot of the code on your phone or just memorize it: R-B-G-B. It’ll save you a lot of tab-switching.
Actionable Next Steps
To make the most of your raid experience, stop trying to solo them as soon as you hit level 1100. Instead, head to the Blox Fruits Discord or join a public server and look for "Raid Hosts." Many high-level players will host raids for free just because they need the Fragments themselves.
Before you enter the code, make sure you have a clear plan for which fruit you want to awaken first. Don't waste Fragments on a fruit you plan to swap out in two days. Focus on a "Grinding Fruit" like Buddha or Magma first, then move on to the PvP fruits once you have a stable way to farm.
Check your Beli balance, head to the Cold side of the island, and punch in that sequence. The lab is waiting.

- Reach level 1100.
- Go to Hot and Cold island (Second Sea).
- Find the secret lab in the snow mountain.
- Input Red, Blue, Green, Blue on the monitors.
- Climb the invisible ladders in the secret room.
- Buy a chip from the Scientist for 100k Beli.
- Stand in the dark blue tube to start.
Once you’ve mastered the basic raid loop, start saving your Fragments. You’ll need at least 14,500 Fragments to fully awaken most top-tier fruits. It sounds like a lot, but with a fast team and a solid Buddha tank, you can knock that out in an afternoon of consistent raiding. Just don't forget the code when you’re rushing back to buy the next chip.
