Divide players into 2 uneven teams e.g. 7 attackers (Blue Team) and 3 defenders (Yellow Team)
The grid can be wider at the start of the game e.g. 30m x 30m but as the players get more efficient at finding space and decision making the grid can be narrowed to challenge them or extra players given to the defence
Each player who receives the ball in the game has a decision to make on where the space and their team mates are.
The object of the game is to get players to look at the defence and then make a decision on what to do next.
The defence only has to touch the player with the ball and that player must stop and pass to another team mate.
The attacking team score by running over the try line
