The twisting, turning tunnel maze race! Break through the grid block in this 3-D tunnel-making game. Your challenge is to create a twisting, turning (or straight) tunnel from one side of the cube to the other, while preventing your opponent from doing the same. Strategically insert blocks, constructing your tunnel while preventing your opponent from taking the lead. The uniquely designed blocks stay firmly in place so you can tilt the cube to any angle while planning your route. Think you have the advantage? Just when you think you're at the finish line, your opponent might push your blocks out of the way! It's a frenzy of challenging, multi-angled strategy for everyone. Includes Tunnelz cube, 16 blocks, and game guide. For two players.
