As Dodge Ball. Play using a largish ball (volleyball or English football (soccer) sized ball works well). One or two players start as the ‘taggers’ and using the ball they have to tag the other players by hitting them below the knee with the ball. Players once tagged join in with the tagging until only one or few players remain in.
A variant rule to keep the game moving quickly: throwers/taggers must throw the ball within 5 seconds or they face a penalty, possibly that the others get to nominate back into play a player who has already been knocked out.
