Abstract: A scoreboard system for use in tournament play such as in golf, tennis and trap and skeet shooting events, which includes a plurality of scoreboard panels which are portable so as to be selectively moved between an outdoor support system and an indoor support system and wherein at least two of the scoreboard panels include two different player grid portions permanently displayed on the front and rear surfaces thereof for accommodating different types of tournaments having differing numbers of players and wherein the panels are reversible with respect to their support systems whereby, when the front surfaces are mounted in display relationship with respect to one another, a first grid pattern is established, and wherein, when the rear surfaces thereof are oriented in a display relationship, either a second or third grid pattern is created.
