El joc vol imitar, amb les limitacions que imposa la pantalla, la pantalla Tip Toe del joc Fall Guys. En la primera fase del joc, un dels contrincants dissenya un camí entre la part inferior de la pantalla i la superior; en la segona part, l'altre jugador ha de trobar el camí i torna a l'origen si no l'encerta.
El programa és el següent:
