I don’t need to move any coins, or change the orientation. I simply add 18 coins to make the triangle point downwards (albeit creating a larger triangle).
When you’re trying to change something or influence someone, you have to move a lot of balls in order to make a difference.
One blogger likes this. The answer was hinted at in my reply to the puzzle, 3 seconds.. 3 moves. Just turn your monitor, or walk to the other side of the table. Then you need to move 0 coins… I like this answer. If the triangle is flat on a table then it doesn’t point downwards, wherever you stand
