Two teams pass the ball to their team mates with an overarm throw which must bounce only once and then must be caught.
Using the throws to advance towards the opposition's grid players must not step inside the grid. When they get close enough they can throw at the stumps. If they miss a team mate can run around the back of the stumps to catch the ball.
If caught that team can have another shot, if the opposition catch the ball they then move back up the field to the opposition's grid.
