This plastic card building system uses patented, diagonally scored, lightweight, thin panels with a tab/slot interlocking system. It allows for bigger, fuller building with high-intensity graphics. The set gives children step-by-step model instructions for creating a 3.5' tall T-Rexerator, and includes a limited edition 1st Series Collector Trading Card model picture. It presents a “new way to build” and includes 300 plastic cards that measure 3.5” by 3.5”. Other sets include the X-Cycle and ShipVenture.
— “Cardtivity builds simple because of its patented 'one card' design. Most of the major brand construction gifts for kids, ages 7+, have brilliant model playsets, but the number of different-sized pieces and their gazillion-page instruction booklets can be mind boggling to figure out,” Chief Imaginologist Jamie Greenberg of Cardtivity told TDmonthly. Launch date: Fall 2007.
