In order to play, you must use the arrow keys to cross the bridge (green) to go faster in the red to get to the win circle (yellow) also evade the defender, if he tags you, you go back to start. >:( But that's how it works. Go to the bridge starter (right pink circle) to move across the bridge. then get to to left pink circle. If you don't do this then you will be slow in the red.
yes this is a Korean schoolyard game. And the way the film crew at Netflix's Squid Game did not play it how it actually works. Hope you enjoy!
