I recently got an email from the creator of a puzzle called Hexa-Trex. As the name suggests the puzzle involves hexagons. The hexagons are laid out in a pattern chosen by the puzzle designer and each has either a digit or an arithmetic operator inside. The goal is to find a path through all of the hexagons exactly once to create a valid mathematical equation. New puzzles are posted every couple of days and the range from very easy to quite challenging. Enjoy.
