Make it a regular hexagon

Imagine pens that hold one animal each, and think about building them with 12 matchsticks. We tend to try making them as squares, but let’s shift that thinking. A triangular pen only needs three matchsticks, so… with a clever combination, you can form a regular hexagon. It’s a surprisingly tricky puzzle!

Move the rightmost matchstick to make “ONE.”

When you're told to “make a 1,” you’d naturally think you have to create the actual shape of the numeral “1,” right? But if you think about 1 in different ways—like “hitotsu,” “first,” “one”—your thoughts start to wander and then you go, “Aha!” That’s why it works. It’s a bit tricky for people who don’t know how to spell the English word ONE.

Move the two vertical matchsticks at the top to the left and right, and move the horizontal matchstick in the top center downward.

Since you only need to make three squares, it seems like there could be infinitely many answers, but if you want a neat arrangement with no surplus or shortage, there’s only one solution. Because there are no constraints regarding the leftover matchsticks, that might be the tricky part of this problem. Please try it with the mindset of “Let’s make exactly three squares with no more and no less!”
