In Chapter 16 of Where the Red Fern Grows, what does the hunter mean when he says, "We should have a jackpot for the winner?"

Back at the camp, another hunter describes seeing the dogs chase the coon through the camp last night. No one skins three coons the last night of the first round, leaving just three teams for the championship runoff. The camp puts together a jackpot for the winner. One of the teams Billy is up against has won four gold cups.
