On the signal to begin players jump one rung at a time till the opposing players meet.

Players that meet play a game of rock-paper-scissors.

The winner jumps towards their opponent's end.

The loser goes to the back of their line and the next player jumps to meet the other team's jumping player.

Play RPS again....

When one player wins RPS at the very last rung their team scores a touchdown. That player returns to the end of their team's line and the first player in each line jump and play continues...
