Bonus Island Online Slot UK

This slot isn’t exactly subtle about its theme. There’s a bearded pirate on the loading screen, a lagoon in the background, and a jaunty soundtrack that will have you wanting to hoist up the Jolly Roger and go sailing for booty. You don’t have to sail very far, though, because this superb pirate-themed online slots game is right here waiting for you. Even the reel set looks like a treasure map, so that makes it a fine place to go looking for treasure!

Bonus Island Developer - Inspired Gaming

If you've been around UK slots for a while, you'll probably have played Centurion. It's generally seen as the best of all the many Roman-themed online slots and remains Inspired Gaming's biggest hit years after it was launched. It hasn't stayed that way for want of trying, though - Inspired has released dozens of slots since then and scored big hits with them. Big Spin Bonus, Jungle Falls UK Slot, and Super Hot Fruits are all very popular - it's just that Centurion Online Slot is such a big deal that it's hard for anything to top it! When Inspired Gaming isn’t hard at work making online slots, the company is busy adding to its Virtual Sports platform. It’s the most popular platform of its kind in the world, which is a fantastic achievement for them.

As pleasant as the lagoon backdrop is to look at, it’s nothing compared to the impressive sight of the enormous reels. They’re a square-shaped 6*5 arrangement, upon which the least valuable symbols are represented by our old friends J, Q, K, and A. They’re as near-worthless as they always are, but they’ve been decked out in gold to make them more attractive to aspiring pirates. Every symbol above them is theme-related, including anchors, cutlasses, cannons, treasure maps and (of course) pirates. Given the modern presentation of the slot, you'd probably expect there to be wild symbols to play with. Surprisingly, there isn't one. To get any bonus action in this slot, you're going to need to string avalanche wins together. Read all about that in the bonus features section. 

Bonus Island Slot Features

Avalanche Wins

This might not be a Megaways slot, but it does have a familiar Megaways feature in the shape of avalanche wins. Each symbol in your winning lines will disappear after it's been counted, and new ones will take their place. If they react with the existing symbols to create more wins, you get more avalanches. The more avalanches you can string together, the more the "Epic Meter" to the left of the reels fills up. That's your way into the slot's most spectacular bonus offerings.

Mystery Symbols

One or more “blank” symbols might land on any spin. They’re indicated by wooden planks with a white line painted across them. These symbols are worthless unless a bomb symbol lands on one of them, in which case the blank symbols explode to be replaced by either matching base game symbols or special coin symbols. The combined value of all the coins is immediately collected, and you move up one step on the “Epic Meter.”

Bonus Island

This is the slot's star attraction. Make it to at least four avalanche wins, and you'll be taken to a new treasure map screen. What happens on that screen depends on how many consecutive avalanches you scored. For four avalanches, you get a prize picker feature that invites you to open treasure chests and win free spins, cash prizes, or a combination of the two. For five avalanches, you get the same prize picker feature, but all the prizes are boosted compared to what you get for four. For six avalanches, every option on the prize picker screen is a powerful free spins prize. You could choose not to enter free spins by accepting a cash offer from the pirate, which is made to you before the round begins. This offer is made before you see the contents of your treasure chests, so it’s a bit like playing “Deal or No Deal.”
