It’s Friday. Let’s have some fun. Now, a warning: Today’s Friday Fun does involve math. It’s called Plupon, as in, “What a lovely game … to Plupon.” The object is to click on three descending number bubbles that add up to either 10 or 20. If they add up to less than 10, they form a new number bubble. There are six levels, and my high score so far is around 107,860. But I’m going back in for more.
