Though basically a children's roll-and-move (or "pop-and-move," seeing as how the game comes with two pop-o-matic devices) there is a bit of thinking here for young minds. Specifically, you can block access to an inner ring by parking one of your marbles on the inner edge of a bridge. Such tactics may frustrate very young players while at the same time introducing them to the "take that!" concept of game play. However, there is no "sending-a-player-back-to-start" rule, which probably helps ease a bit of frustration.
