Coordinate art
Plot points on a grid and connect the dots to draw a picture. Every spot has an address — an (x, y) pair.
How to play
Click anywhere on the grid to plot a point. The line connects them in order. Try a preset, or design your own.

How coordinates work
Every point on the grid has two numbers: the first is its position left/right (the x), and the second is up/down (the y). The middle of the grid — where the two heavy axes meet — is (0, 0), called the origin.
- (3, 2) means: 3 right, 2 up.
- (−4, 1) means: 4 left, 1 up.
- (0, −5) means: don't move sideways, 5 down.
Try a preset
Tap House, Star, or Diamond to see how a few points and the line connecting them is enough to draw a shape. Then start over and design your own.
Why this matters
The whole field of coordinate geometry — and most of computer graphics — is built on this one idea: turn shapes into lists of points, then turn the points back into shapes. Even the characters on this screen are drawn that way.
