Game overview<\/strong><\/h2>\n\n\n\n

Inspired Entertainment\u2019s Bonus Island takes you to an idyllic beach on a faraway atoll washed by the ocean waves and filled with chests of buried treasure. The game loads to reveal a 6×5 symbol grid populated by cascading symbols with pirate themes such as swords, muskets, treasure maps, and ship anchors, with the pirate captain as the top-paying symbol. The game moves along at a fast pace to a jaunty soundtrack that reminds you of pirate movies. Unlock the bonus feature to discover what makes this specific game stand out from other online slots<\/a>!<\/p>\n\n\n\n

All in all, here you have yourself a cheerful, colorful slot that boasts 15,625 ways to win, with a maximum potential payout of 25,000x and an RTP (return to player) of 95.78%. In other words, on average, it should award you with small but consistent wins.<\/p>\n\n\n\n

How to play<\/strong><\/h2>\n\n\n\n

Any time you play slots online, it\u2019s a good idea to check out the paytable to familiarize yourself with the paylines and symbol values. Once you\u2019re done with that, use the buttons above and below the coin button to raise or lower your bet amount in line with your bankroll and your budget. Press the coin button to see all the bet options available to you.<\/p>\n\n\n\n

Now you\u2019re ready to play. You can press the \u201cSpin\u201d or select Autoplay and enter the number of spins you\u2019d like as well as your loss limit. Like most casino slot games, the aim is to land winning combinations of three or more matching symbols on adjacent reels, starting from the left. Every winning combination triggers cascading reels. When this happens, the winning symbols pay, then disappear, and new ones land in their places, which multiplies the winning possibilities.<\/p>\n\n\n\n

Graphics<\/strong><\/h2>\n\n\n\n

When Inspired crafted Bonus Island, they went all in to create a fun mood without being too goofy (after all, there\u2019s always the chance of serious wins!). The graphics fit the gameplay perfectly. It\u2019s easy to imagine you\u2019re on the beach of a real desert island, with rocky cliffs and ocean waves providing an engaging sense of movement. The symbols on the reels are bright, bold and quirky, with satisfying explosions that tell you when you\u2019re about to have a Mystery Boost.<\/p>\n\n\n\n

Features<\/strong><\/h2>\n\n\n\n

The Mystery Boost feature is what makes Bonus Island one of the best online slots we\u2019ve seen in a while. It\u2019s simple but effective and it really drives the game. Look out for symbols that look like three planks of wood with stripes painted on them. These are the mystery symbols, and they\u2019re your ticket to go treasure hunting. That said, they do nothing on their own \u2013 but if you land a bomb symbol, all the mystery symbols explode and identical paying symbols or coin symbols land in their place.<\/p>\n\n\n\n

If these new paying symbols form more winning combinations, the reels keep cascading. If a mystery symbol is replaced by a coin, it triggers the Coin feature: Coins spin on the reels until their cash values are revealed and added to your win. Then the coins cascade to other positions on the grid.<\/p>\n\n\n\n

Bonuses and jackpots<\/strong><\/h2>\n\n\n\n

Many casino slot games have cascading reels, but the cascades in this slot go one better. Every time you set off a cascade, you go up a level on the cascade meter left of the reels. Achieve four, five or six cascades in a row, and you\u2019re awarded the Bonus feature, the Mega Bonus feature or the Epic Bonus feature.<\/p>\n\n\n\n

In the Bonus feature, a treasure map appears with 20 treasure chests you can select from. The chart below the map shows all the possible prizes. You select a chest and a pirate flag marks that it\u2019s yours, but you don\u2019t get to see the contents. Then you select three more treasure chests to eliminate. They reveal their prizes, but you can\u2019t keep them. Instead, they gray out on the chart.<\/p>\n\n\n\n

Eliminate three boxes and the pirate captain offers you some cash. If you turn the offer down, you have to eliminate three more chests and choose again. This continues until there\u2019s only one chest left, as well as your original mystery chest with the flag. Which chest will be your final choice?<\/p>\n\n\n\n

Once you\u2019ve decided, you have one more choice to make. A gamble wheel appears, like something out of casino table games<\/a>, and you can either keep your prize or spin the wheel and hope for more. The gamble: You lose some of your prize if you fail.<\/p>\n\n\n\n

The Mega Bonus works the same, but with bigger rewards. The Epic Bonus is different. You only have 10 selectable treasure chests instead of 20, but they contain different amounts of free spins. Every cascade during free spins increases the no-limit win multiplier.<\/p>\n\n\n\n

In free spins, the Mystery Boost symbol changes to a barrel with a skull that randomly transforms into a symbol or a coin that activates the Coin Bonus feature. Here, coins award cash prizes and free spins while setting off cascades and increasing the win multiplier.<\/p>\n\n\n\n
