There are 3 bonus features available in the Adventures of Doubloon Island slot game. These 3 bonuses are free spins, the HyperHold, and the Win Booster. The Treasure chest Scatters are the key to the free spins. They will trigger when 3, 4, or 5 land on the Adventures of Doubloon Island reels, awarding 10, 15, or 20 free spins respectively when this happens. Triple Edge Studios added another special touch to this feature by removing all the low-paying icons. Only the premium-pay online slots icons will land, and the free spins can be retriggered. Land another 3, 4, or 5 Scatters and you’ll get another 10, 15, or 20 free spins. Adventures of Doubloon Island also has HyperHold symbols, named after the feature they trigger. You’ll be awarded with 3 spins when at least 3 land on the reels and the triggering icons will then lock into position. Whenever another one appears, the spins will reset and this part of the game ends when either the spins run to 0 or all the reel positions get filled. Whichever outcome occurs, the HyperHold online slots symbols will transform as the feature closes, revealing cash prizes of between 1X and 50X the active bet if the Win Booster is not active. If it is, this potential prize money increases to between 2X and 100X the total wager.
These HyperHold slot machine icons may also reveal 1 of the 4 jackpots, the Mini, Minor, Major, and Mega. Worth 25X, 100X, 500X, or 2 000X the active wager if the Win Booster function is off, their value increases to 33.33X, 133.33X, 666.67X, or 3 333.33X the triggering bet if the Win Booster is in play. The Win Booster is an optional game function that increases the value of your Adventures of Doubloon Island online slot bet by 1X5 if you activate it. While it doesn’t alter standard game payline wins, it does improve any payouts incurred during the HyperHold feature. Cash prizes swell by 3X and jackpots get a boost of 2X and 2.5X. The Win Booster can be turned on or off at any point during play.
