PixelQuiz is a fun picture-guessing game where you need to guess the prompt for computer-generated pixel images themed on video games, movies, etc. (I exclusively played the video game categories)

It's weird trying to interpret a "mind's eye" vision of what a game looks like, but surprisingly often you can see what looks like an unstructured mess of colourful pixels and your brain immediately says "Ah yes, this is obviously Crash Bandicoot."
