If you watch professional golf on TV or you even play golf occasionally, you probably have seen a golf scorecard littered with circles and squares on it, and you've probably wondered what those shapes mean in golf.
Golfers use circles and squares on a scorecard to indicate their scores against par, giving them an easy way to tally up their score instead of adding the numbers together.
A circle around a number on a scorecard indicates a score under par. So, for a birdie, a player puts one circle around the score. For an eagle, a player puts two circles around the score. And in the event of the very rare albatross (incorrectly called a double eagle), a player could put three circles around the score.
A square around a number on a scorecard indicates a score over par. So, for a bogey, a player puts one square around the score. For an double bogey, a player puts two squares around the score. And it goes on like that.
Typically, especially when golfers' scorecards are shown on TV, there will never be more than two squares around a number, even if a player makes worse than double bogey on a hole. This is also true for the albatross or even a condor, and that's because it looks a bit unwieldy to have so many circles or squares surrounding a number. Then again, if any of us made an albatross or condor, we'd probably put stars and exclamation points around it before we framed the scorecard.
By using circles and squares instead of adding numbers to get a score, a golfer just has to keep track of a count that starts at zero. The idea of to have more circles than squares on the card. Then, with that number at the end of nine holes, a player can add that number to the par for the side and get their nine-hole score.
