It had some name such as 'Time Bomb' or 'Grenade' you may have seen it. Divide the group into two equal teams. Find a suitable playing field about the size of a soccer field, with an area to be used as an end zone. The play starts with a jump ball. The object is to move the ball down the field to score points.
Players throw the ball to their teammates, or run with the ball.
Players may not take more than five steps while carrying the ball. If they do, the ball is handed to the other team, who throws it in from the sidelines. Points are scored when the ball is thrown to a teammate in the opposing team's end zone, and caught. The ball must be thrown from outside the end zone into the end zone and caught by a teammate. If the ball is missed or dropped, the opposing team gets a chance to move it out of their end zone.
