In Free Fire, your gun skill determines if you get the kill. But your Gloo Wall skill determines if you survive to loot the box. It is the single most unique mechanic in the Battle Royale genre. In games like PUBG or COD Mobile, if you get caught in an open field, you die. In Free Fire, you build a castle instantly.
However, watching a pro player deploy walls is very different from doing it yourself. They look like they are dancing. Their walls appear before the bullet even hits them. How? Is it a macro? Is it PC only? No.
It is pure muscle memory and HUD optimization. In this massive guide, I am going to break down the physics of the “Sit-Up Gloo Wall,” the finger placements for the “360 Wall,” and the psychological warfare of using walls to confuse enemies in a 1v4 situation.
Part 1: The Physics of “Sit-Up” (Why Crouch?)
Every tutorial tells you to crouch (sit) before placing a wall. But very few explain why. Understanding the “Why” will help you fix your mistakes.
Reason 1: The Spawn Distance
When your character is standing, the game logic calculates the Gloo Wall spawn point based on your camera angle. If you are looking straight ahead (at the enemy), the wall spawns about 2-3 meters in front of you.
The Problem: A wall 3 meters away leaves a gap. If the enemy is on high ground, or if they rush you, they can shoot over the wall or shoot your feet under the gap.
The Fix: When you crouch, the game logic pulls the spawn point closer to your hitbox. The wall spawns literally touching your knees. This creates a seal. No bullets can pass under or around it.
Reason 2: Animation Cancelling
Free Fire has an “Exit Fire” animation. After you drag up to shoot, your character’s hand stays up for a split second. This is called recovery frames.
Pressing the “Crouch” button interrupts this animation instantly. It forces the character model to reset, allowing you to perform the next action (placing the wall) faster than if you waited for the standing animation to finish.

Part 2: The 3-Finger Setup (Mandatory for Speed)
If you are playing with 2 thumbs, you have a speed limit. Your right thumb has to do too much work (Aim -> Shoot -> Drag Down -> Tap Wall -> Tap Place). That is 5 actions for 1 thumb.
To reach “God Speed,” you need to offload work to your Left Index Finger.
The “Triangle” HUD Layout
- Left Index Finger: “Left Fire Button” (Always On). Place this in the top-left corner.
- Left Thumb: Movement Joystick + Gloo Wall Button. Place the grenade slot near the joystick.
- Right Thumb: Aiming + Jumping + Crouching + Weapon Switch.
The Execution Flow
With this setup, the “Sit-Up Wall” becomes a fluid motion involving 3 fingers simultaneously:
- Right Thumb: Drags Up (Shoot) -> Drags Down (Aim at feet).
- Right Thumb: Taps Crouch.
- Left Thumb: Taps Gloo Wall button.
- Left Index Finger: Taps Fire (To place).
Because the “Select Wall” and “Place Wall” actions are done by the Left Hand, your Right Hand is free to focus purely on aiming the wall placement. This is how pros place walls instantly.
Part 3: The 360-Degree Gloo Wall (The Turtle Shell)
The 360 wall is the ultimate defense. You are running in an open field, and suddenly a full squad shoots you from North, South, East, and West. A single wall won’t save you. You need a bunker.
Sensitivity Requirement
You cannot do a 360 wall with low sensitivity. Your “General” sensitivity must be 100. If you are on a low-end device, you might even need to increase your DPI (as discussed in previous guides).
Step-by-Step Execution
- The Crouch: Sit down immediately.
- The Grip: Hold the “Left Fire Button” with your Left Index Finger. Do NOT let go.
- The Spin: With your Right Thumb, swipe horizontally across the screen as fast as possible.
- The Result: Because you are holding the fire button while spinning, the game will “paint” Gloo Walls in a circle around you.
Common Mistake: Spinning too slow. If you spin too slow, you will place walls inside each other, wasting them. You need a violent, fast swipe.
Part 4: Offensive Gloo Walls (The “X” Rush)
Walls aren’t just for defense. Aggressive players use them to close the distance.
If you run straight at an enemy, they will drag-headshot you. You need to Zig-Zag with walls.
The “X” Pattern
- Run diagonally Right.
- Jump -> Turn Camera Left -> Place Wall.
- Run diagonally Left (through the wall).
- Jump -> Turn Camera Right -> Place Wall.
You are essentially creating a staircase of cover as you rush. This forces the enemy to constantly readjust their aim. They can’t lock onto you because you are constantly cutting the line of sight.
Part 5: 1v4 Mind Games (Separating the Squad)
When 4 players rush you, walls are your only tool to separate them.
The “Back Wall” Trick
If you are running away into a house, place a Gloo Wall to block the door behind you. This buys you 5 seconds to heal or reload while they break it.
The “Cage” Trick
If an enemy rushes you recklessly, you can sometimes place a Gloo Wall behind them, trapping them between you and your wall. They will panic. They can’t back up. This guarantees an easy kill.
The “Fake Peek”
Place a wall. Run to the right side of it, but stop just before you are visible. The enemy will see your movement and pre-fire. Wait for them to stop shooting, then jump out and kill them.

Part 6: Troubleshooting Your Wall Speed
If you feel slow, check these three things:
- Button Size: Is your Gloo Wall button at 100% size? If you miss the button by 1mm, you die. Make it huge.
- Transparency: Lower the transparency so it doesn’t block your view, but keep the hitbox large.
- Ping: If your ping is 150ms+, your walls will always have a delay. This is server-side lag. In this case, you must place walls earlier (pre-firing walls) rather than reacting.
Conclusion
The Gloo Wall is what makes Free Fire skill-based. Anyone can aim, but only a master can build. Don’t go into Ranked until you spend 10 minutes in the Training Ground “Gloo School.” Practice the Sit-Up motion until your thumb hurts. Then practice it some more. When it becomes instinct, you will feel invincible.
