Tug-of-war is a traditional game in which two teams pull on opposite ends of a ROPE in an attempt to gain control of the ROPE. The item used for this game is a ROPE, which is typically made of a strong material such as hemp or nylon. The ROPE is usually around 10-20 meters long and is secured at both ends with a knot. The ROPE is also often marked with a center line to indicate the middle of the ROPE. The goal of the game is for one team to pull the ROPE so that the center line passes over the other team's side.
