Bonus Island Slot Review
Inspired Gaming transports you to Bonus Island in this 6x5 pirate-themed slot, with 15,625 ways to win and a top payout of 25,000x your bet. In our Bonus Island review, we’ll explore the diverse bonus features (e.g. Mystery Boost and the Free Spins Bonus), RTP, and much more!
Bonus Island
Bonus Island RTP and Wagering
Bonus Island uses 6 reels, 5 rows, and up to 15,625 ways to win. The minimum bet is £0.20 and the maximum is £20.00.
To create winning combinations, you need to land at least three identical symbols across adjacent reels. Bonus Island includes cascading reels: all winning symbols disappear and new ones drop in to replace them. Cascades can help you win more than once on a single spin, and they can trigger the Bonus Island feature (which we’ll get to later).
Bonus Island has medium volatility: payouts may be fairly small and regular, but there’s still the potential to win big prizes.
Unfortunately, Bonus Island’s Return to Player (RTP) is 95.78%, which is below the average for a slot (96%). It’s not the lowest RTP we’ve seen, but there are still plenty of other slot games out there with a much higher RTP.
Still, the biggest win available is far bigger than you might expect — 25,000x your bet. Most symbols only award modest payouts, but the bonus features offer good opportunities to take your winnings higher.

Bonus Island Symbols and Audio & Video Design
Bonus Island features cartoony graphics and animations that bring the tropical setting to life. The reels are surrounded by a peaceful sandy beach, with water lapping at the shore while clouds drift across the crisp blue sky. The exciting music suits the pirate theme well, too.
There are 10 standard symbols in Bonus Island. These include the Pirate, Anchor, Pistol, Sword, Treasure Map, Telescope, Ace, King, Queen, and Jack. The Pirate awards the biggest prize: between 2x and 10x your bet.
Other symbols include the Mystery symbol, Transform symbol, and Coin symbols. Unlike most slots, Bonus Island has no Wild symbols.

Bonus Island Mobile Features
Bonus Island is compatible with mobile devices, as it was developed with HTML5 technology. You can play it on a smartphone or tablet as well as on a computer. The game looks great on a smaller screen, and it was made to be played in both portrait and landscape mode.
Bonus Island Bonus Features
Bonus Island includes a strong range of bonus features that adds depth to the game and brings you more chances to rack up wins. Let’s find out how they work.
Mystery Boost
Mystery symbols can land on any reel, but only become activated when Transform symbols appear too. The Transform symbols explode and turn all Mystery symbols into identical standard symbols or Coin symbols.
Coin Bonus
The Coin Bonus starts when Transform symbols turn Mystery symbols into Coins. Those Coins have cash prizes and spin on the reels where the Mystery symbols landed. When Coins stop spinning, their cash values are awarded. Coins then cascade and put one position on the Cascade Meter.
Bonus Island Feature
You can trigger the Bonus Island feature by getting four or more consecutive cascades in one round. Each cascade fills one position on the Cascade Meter. The number of consecutive cascades determines how many cash prizes and free spins will be on the map during the feature.
The Bonus Island is played on a map of the island, and you need to choose three chests across multiple rounds until just two chests remain. After you complete a round, the pirate captain makes a cash offer. Accept it to claim the prize offered or reject it to keep playing.
In the final round, you’ll pick one of the last two chests. It will either contain free spins or a cash prize. If it’s free spins, you’ll trigger the Free Spins Bonus!
Free Spins Bonus
The Free Spins Bonus includes an unlimited win multiplier, which increases with each cascade. Mystery symbols may appear and can trigger the Coin Bonus, which awards cash prizes and extra free spins.
You can also gamble any free spins and cash prizes from the Bonus Island feature for extra free spins.
Spin Chance
Spin Chance allows you to bet your remaining credit to potentially win an extra spin at your current wager.
Bonus Island Final Thoughts
Bonus Island is a fantastic pirate-themed slot with fun visuals and a varied mix of bonus features.
Plus, the cascading reels mechanic can lead to consecutive wins on a single spin, and there are more than 15,000 ways to win. The high maximum win of 25,000x your bet is another positive point.
The only real drawbacks are that the standard prizes are fairly small without multipliers, and the RTP is lower than average (95.78%).
Rating: 8.5
