Just put the ring with the tumbling flaps around the existing hole. In a Quiccup game the flagstick always stays in the hole and may be hit by the ball without penalty.
If the ball is inside the Quiccup it is considered as ‘holed’. One or more balls do not need to be removed before another player putts.
Around and on the green, there is no order of play, when all the balls have a chance to be holed and no player has requested to mark a ball. When you are ready you may putt.
If the ball comes to rest on the outer flap just add one stroke and lift the ball to avoid damage tot he Quiccup.
If the ball comes to rest on the not completely tumbled flap on the inside of the Quiccup the ball is considered as ‘holed’.
