Every square has a number — color them to find the hidden picture!
What it does. A paint-by-number puzzle where every square is labeled with a number, and coloring in the matching color for each number reveals a hidden picture underneath.
Why it's built this way. The first eight pictures use only 0 and 1, the same two values a computer actually uses to store an image, so filling in the grid is a hands-on preview of how a bitmap image works before anyone hears the word "binary." Later pictures open up into full color once the pattern clicks.
It's just a fun puzzle too. No score, no timer, no pressure, color it, see the picture, color the next one.
