This Android game was inspired by the South Korean survival drama television series Squid Game. 

In Squid Game, hundreds of contenders who are in deep financial hardship accept an offer to participate in children's games for an enticing prize, but the consequences are potentially lethal. Players are required to wear green tracksuits and are constantly monitored by masked guards in pink jumpsuits, with the games overseen by the Front Man, who wears a black mask and a black uniform.

In this mobile version, players must maintain their focus in order to stay alive and win the game. When the light is green, the players can walk towards the line; however, when the light turns red, they must stop moving in order to avoid the penalty.
