There are 20 fixed paylines in the Adventures of Doubloon Island slot game, and all wins must go from left to right. By activating the Win Booster, you can increase the size of your wager by 1.5x. While this won't alter the payouts for regular wins, it does increase the jackpot sizes and the cash value of the HyperHold symbols.

  • Coins and How Betting Works: There is a wide selection of betting options, beginning with the $0.10 minimum bet and extending all the way to a $40 max bet. However, all regular wins are based on the line bet, which you can calculate by dividing the total bet by 20. The jackpot and scatter payouts are based on the total bet.
  • Symbols: There are four pirate-themed high-value symbols. The captain, in a red circle, is the top paying symbol. He is followed by his first mate, a parrot, and a pair of crossed swords. The four low-value symbols are playing card symbols; spade, heart, club, and diamond.
  • Wild: The female pirate is the wild, and she can appear as a single, double, or triple stacked symbol. It can substitute for any of the regular symbols to create a win.
  • Scatter: The treasure chest is the scatter, and it starts paying out a win when there are at least 3 anywhere on the reels. Additionally, it will trigger the Free Spin feature.
  • Bonus Symbols: There are gold coin symbols with a cash value that can show up on the reels. These are the HyperHold symbols. If there are at least six on the reels at once, it will trigger the HyperHold feature.

  • Bonus Features: To activate the Free Spin feature, you will need 3, 4, or 5 scatter symbols on a single spin. The number of free spins is based on how many scatters you have and can be either 10, 15, or 20, respectively. The scatter symbol remains on the reel during the feature, and you can win additional free spins.

    The HyperHold feature is triggered when you have 6 or more HyperHold symbols on the reels. The HyperHold symbols will remain locked on the reels, and you'll receive three free spins. If any new HyperHold symbols appear during the spins, the count will reset at three. A special Golden Skull HyperHold symbol is added to the reels as well. The feature ends when the entire reel is filled with these symbols, or three spins occurred without any new HyperHold symbols. Each symbol will reveal either a cash prize or one of the four jackpots. At the end of the feature, you will collect all prizes shown on the reels.
