Mark a rectangular grid of lanes on the ground, with one guarding player stationed on each dividing line.

Guards can only move forward and backward or side to side along their own line, never leaving it.

Runners from the other team try to dash through every lane from the start line to the far end and back.

Being touched by a guard, or stepping on a line rather than crossing it cleanly, puts a runner out.

After a set number of attempts the teams switch roles; whichever team gets more runners safely through wins.
