Since the game has only 9 paylines and there is no free spin, the main attraction of the gameplay is to win the grand prize. Captain's Treasure has a jackpot, meaning that players may receive unlimited caps: it increases the jackpot pool whenever any player bets a game anywhere. If the correct combination is present, those with a dollar ball side bet feature can add this further and have a chance to win the jackpot. The jackpot can also be won in part, and the provider places a "seed" so that even if the jackpot is just won, the player is determined to have a chance to get a good result.
