This is a simple target practice game, good for honing in on accurate passes. The game implies that you have some good trees within close proximity of your practice field, but if not then find an adequate substitute (trash cans, benches, water fountains, flagpole, etc.) or just go with cones.
Let your players know what the target is (a decent distance away), and the goal is to hit it by using the fewest number of passes.
To add variety, set up a multi-hole course, or add obstacles (around the port-a-pot, through the gate, over the fence, etc). Also mix in using the opposite foot and outside of the foot.
This game doesn't involve much running, but is good to use in between other more active exercises.
