Click on any two tiles at a time and they will flip over and each reveal their objects. If the objects are matching, then that means you guessed correctly. If the objects are different, then they will flip back over. Get all the matching pairs to win. You will need a lot of concentration and a good memory (and luck will help) to win with the least amount of guesses.
Most of the art was from the Scratch costume library, but all of the code was by me.
