Features: Isn't it too tiring to row Domino one by one? Line them up with the help of your domino train and start the chain reactions! By simply pressing the quick-load domino magazine on to the domino, your colorful blocks go up into the holder and stay until your train releases them as it travels over the floor or table, leaving a perfect row of Domino just waiting to be knocked down. Either way, it is fun and helps develop color recognition, cognitive abilities, spatial relationships, and teamwork.
