Game Is Hard Level 213 Walkthrough: Fix the Plane

Level 213 shows a Cartesian coordinate plane (an X-Y grid) with “fix this” as the instruction. The quadrants have incorrect sign labels, and your job is to set the correct signs: the top-right quadrant is (+, +), top-left is (-, +), bottom-left is (-, -), and bottom-right is (+, -).

A Cartesian plane with the wrong signs — correct each quadrant. Prefer YouTube? Watch it there →

⚡ Quick Answer

Set each quadrant’s two signs correctly: top-right + +, top-left - +, bottom-left - -, bottom-right + -. This matches the standard Cartesian convention.

Game Is Hard Level 213 Breakdown

What You See

A cross-shaped coordinate plane divides the screen into four quadrants, each with two sign placeholders (plus or minus). The instruction says “fix this,” implying the current signs are wrong.

The plane is the standard X-Y axis: x increases to the right, y increases upward. Each quadrant should be labeled by the signs of x and y in that region — and the current labels are scrambled.

Why You're Stuck

I got confused about which quadrant gets which sign, mixing up top-left and bottom-right. I knew the plane convention, but the on-screen labels made me second-guess whether x was horizontal or vertical.

The convention is: top-right is (+, +), top-left is (-, +), bottom-left is (-, -), bottom-right is (+, -). Once I anchored on “top-right is all positive,” the rest followed from flipping signs as you cross each axis.

The Answer

Fix the four quadrants to the standard Cartesian signs: top-right (+, +), top-left (-, +), bottom-left (-, -), bottom-right (+, -).

How to Beat It

  1. Anchor top-right. Set it to (+, +) — both x and y positive.
  2. Top-left. Set to (-, +) — x negative, y positive.
  3. Bottom-left. Set to (-, -) — both negative.
  4. Bottom-right. Set to (+, -) — x positive, y negative.

Troubleshooting

  • Quadrant signs feel reversed: remember: the first sign is x (horizontal), the second is y (vertical). Top-right is (+, +), bottom-left is (-, -).
  • Mixing up left and right: x is positive on the right, negative on the left. y is positive on top, negative on the bottom.
  • Not sure which is the default: standard convention: top-right (+, +), top-left (-, +), bottom-left (-, -), bottom-right (+, -).

Why It Works

The level is a math-literacy check disguised as a “fix it” puzzle. It assumes you know the Cartesian plane convention — x positive to the right, y positive upward — and asks you to correct scrambled quadrant labels. The challenge is purely in mapping the abstract (x, y) sign rules onto the four visible quadrants without transposing the axes. Once you lock in one quadrant, the others are symmetric flips.

The Rule to Carry Forward

On a coordinate grid, x is horizontal (right = +) and y is vertical (up = +) — label each quadrant with its (x, y) sign pair, anchoring on the top-right (+, +).

  • First sign is x (horizontal), second is y (vertical).
  • Top-right is (+, +); flip each axis sign to get the neighbors.
  • Bottom-left is (-, -) and top-left is (-, +), bottom-right is (+, -).
Pro tip:

Start from top-right (+, +) and flip one sign at a time as you move across each axis.

Common mistake:

Transposing x and y or mislabeling the left/right quadrants. Anchor on top-right (+, +).

Which axis is x in Game Is Hard Level 213?

X is horizontal (right is positive), and y is vertical (up is positive). The first sign is x, the second is y.

Why are my signs wrong in Game Is Hard Level 213?

Check you haven’t transposed x and y. Top-right is (+, +), and each neighbor flips one sign.
