This was always one of my favourite puzzle games growing up. I had a plastic copy of it that I would spend hours rearranging.

For those who aren't familiar with this puzzle, the goal is to take the 12 pieces and make a 10x6 rectangle. The 12 pieces are known as Pentominos, and each one is a unique arrangement of 5 squares connected on the edges. There are more than 2000 different ways to arrange the pieces into a 10x60 rectangle.

It's a lot of fun!
