New to Fortnite? If you're an entirely new player or you tend to play Zero Builds, you may be confused about all the building techniques. "Crank 90s" refers to rapidly building an upwards tower using ramps, walls, and floors in a specific way. We'll show you everything you need to know about cranking 90s in Fortnite.

What is Cranking 90s in Fortnite?

Cranking 90s in Fortnite refers to a building technique that creates a tower as you move upwards. It involves building a ramp, three walls, a floor, and then a new ramp before it repeats. This technique can be done rapidly with enough time and practice.

Crank 90s is a Fortnite term that describes the building technique used to create a tower quickly and efficiently. The maneuver is as follows: ramp, walls, floor, and repeat. On the next ramps you build, you'll need to turn your character 90 degrees before continuing the next set of walls and floor. Some players will skip the floor and just jump before placing the next ramp to get a height advantage quickly, but be sure to place down floors here and there.
- "Cranking" refers to the rapid building, and "90s" refers to the 90-degree angle you turn as you build upwards.
- While it can take some time to get the movement down, you'll be able to master it just as well as any other Fortnite maneuver.

Build three walls in a clockwise, circular motion. The easiest way to do this is to start the wall at the top of the ramp, and then drag your mouse to the right, and then down. This builds a wall at the top of the ramp, a wall to the right of the ramp, and then a wall below that one.
- You should now be looking in the direction of the last two walls built.
- This effectively creates a 90-degree wall.
Prepare to build a floor and a new ramp. This must happen while you're in the air.
The new ramp should now be facing 90 degrees from where you began.

Run to the top of the ramp and repeat. You'll need to build three more walls in a circular motion. Jump, and then place a new floor and ramp.
- You can do this as many times as you can, but keep in mind that you may get jumping fatigue. To prevent this, you can alternate between regular 90s and infinite 90s.
