Squid Game's Gong-Gi

Gonggi, also known as the squid game, is a popular Korean cultural game played with five stones. The game begins by throwing stones from the palm of your hand into the air onto a surface. From there, you can only pick up one stone at a time by tossing it into the air and catching it with the same hand. Repeat this process until no colored pebbles remain on the surface.
