The Modular Dice Tower model is comprised of four dice cups. Individually, the dice cups can serve the quartet of gamers in their quest. No more running after a runaway die or crawling under the table searching for the game piece that jumped off the edge. Just put your dice inside a small cubical box and give it a good shake. Put your dice cup back on the table and simultaneously push the buttons on the sides. This will release the bottom of the box with your dice sitting in it. Now it is time to make your move!
