Symmetrical Pixel puzzles

Play with symmetry and explore how computers store pictures with this Pixel puzzle.

Computers store pictures as numbers. They break the image up in to lots of small squares, called pixels. A number giving the colour of each pixel is stored.

With symmetrical puzzles you only need half as many numbers to recover the original picture. Use symmetry to fill in the rest.

Compressing an image just means finding a way to store it as fewer numbers like this. Ideally you want ways that work for any image though.

Colour in the squares in the puzzles below using the colours from the colour key to reveal the original pictures.
