This game struck testers at first as looking like a cross between Tetris and Jenga. With a recommended age of 4 and up, they were more than a little skeptical. That was until they let their children spend a little time with QUADEFY. Almost every parent told us that they were surprised how quickly their children picked it up and began demonstrating their understanding of geometric patterns. The game itself is sturdy and durable thanks to the wooden pieces and base. Getting started is simple, in fact it is quite easy to learn. It pushes the capabilities of a child’s mind and allows them to explore strategic thinking, creativity and problem solving.
