Análisis de la app Hexaflexagons para 16 de mayo

Hexaflexagons are the ultimate paper puzzle. This app helps you design them so that you can print and fold them at home. What is a hexaflexagon, you ask? It's a hexagonal paper puzzle that has a front side, a back side, plus hidden sides that you can reveal if you flex the paper in just the right way. 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. Pricing: After printing 5 hexaflexagons for free, a $3.99 in-app purchase buys you unlimited access to have hexaflexagon designs emailed to you so that you can print, fold, and solve them. For the hexaflexa-pros: Yes! This app lets you make both tri-hexaflexagons and hexa-hexaflexagons.
