The white panther is 10% faster than the players and can also turn invisible. Its ability to turn invisible will stump most people, but not Kelvin. He had too many means to find it.
He could sense it with his Life Domination ability, Mind Overseer, and Extraordinary Perception. So the white panther of the third obstacle wasn't that much different from the second obstacle.
He destroyed the third obstacle easily and moved on. For his efforts, he gained 9 game points, so he had earned a total of 18 game points.
Others didn't have things so easily. Almost everyone passed the second obstacle with only one elimination.
So 37 players reached the third obstacle. But many of them were eliminated at this junction.
The problem was the invisibility of the white panther. It stumped many players and rendered most of their abilities useless.
