Hexaflexagons are the ultimate paper puzzle, and this app helps you design and make them. What is a hexaflexagon, you ask? It's a paper puzzle that has a front side, a back side, plus hidden sides. It's fun to give them to your friends to see if they can find the hidden sides. Hexaflexagons are great for sending secret messages. Or as photo gifts. Or birthday cards. You can customize your own hexaflexagon or start from one of our designs. Please note that after a limited trial, a $3.99 unlimited use upgrade is required in order to have the app send you designs that you can print and fold at home.
