Finally, a race track not only protects them, but is an absolute blast for kids and adults of all ages! The C4 (Criss Cross Collision Course) is 75 ft long. The game can competitively accommodate 2 zorbies at a time, and is filled with loads of obstacles and varied terrains. For an added splash, the C4 has four water traps that can be filled with a couple of inches of water that add a whole new dimension to the game! You see, when the player transitions from the dry track to the water trap, they hydroplane over the water and can lose traction allowing them to slow down and even lose total momentum, causing them to spin without gaining any ground for a short time. This can be all that is required for the other player to catch up and pass the other player. The game operator as well as spectators can stand near the middle of the game and have a clear view of the players as they race to victory lane. Hours and hours of fun!
