The one thing that is not allowed is any kind of physical contact with the frog. each frog is given 15 seconds to jump three times.once a frog has made its three jumps,an official measures the distance from the center of the pad to the spot where the frog landed on its third jump. naturally,the winning frog is usually the one that jumped in the straightest line rather than zigzagged around.some frogs frustrate their "jocker" by jumping back toward the launching pad after a spectacular first or second jump.
