The deck consists of numbered hexagonal cards in three colors and the wild card. The number of ways to play is limited only by your imagination. The game comes with a set of rules outlining several different games you can play with the Hax deck and once you've familiarized yourself with the game feel free to develop your own rules and post them online on the Hax forum for others to play. Hax is a great way for teachers to have their students learn mathematics while having fun doing it and is a lot of fun playing with your friends and family too!
