POGs were a popular game during the mid ‘90s. Players make a stack of pogs, also known as milk caps, and take turns dropping a heavier "slammer" object onto it, causing the caps to scatter. Each player keeps any face-up caps and is to restack the face-down caps, repeating the process until none land face down, at which point the player who collected the most caps wins the game. POGs also happen to take the same circular shape of a POAP.
