The goal is to score. The player who scores stays in the game, while the player who misses or the goalie who stops the ball is out of the game.
The team with 1 or more players remaining last wins.
The player who has been goalkeeping makes sure the balls are returned to the coach until players are finished. After that, those players take over.
In groups A through D, players must shoot the ball in front of the 16-yard line. Beyond is off. For groups E through J, the line is halfway between the 5-meter area and the 16-meter line.
One group starts with goalkeeping, in this case red.
The trainer plays the ball in and the player from blue runs in and shoots directly at the goal. Don't assume first, then you're off.
If he hits, he goes goalie and rejoins his group. If he misses, he goes to goal and then collects balls.
When a player has shot at goal, hit or miss, the next ball from the opponent goes to goalkeeper.
