Solve simple colour-by-number and logical thinking puzzles and gain a deeper understanding of image representation and compression.
Pixel puzzles turn the ways images are represented as a series of numbers representing pixels into puzzles.
They come in various forms from a simple variant of colour-by-numbers to more complex puzzles based on compression where images are represented by fewer numbers so take up less storage – but can you get them back!
Each representation needs its own algorithm to follow to get the image back.
Colour the grids or make them from Lego, or even use them as needlepoint/tapestry patterns!
