Can you solve the 12 dot puzzle? There is a popular version of this puzzle with only nine dots, but this one upps the ante. Start with a grid four dots by three dots, evenly spaced. The challenge is to connect every dot with five straight lines. However, each line must connect to the last (think about a pen you cannot pick up from the paper). The twist to this is that the last line must end at the beginning of the first line. The end result will have no clear beginning or end. Did you come up with the crazy shape that connects every dot?
