Bonus and jackpots for Bonus Island (Rating of 3.5/5)

Bonus Island has one of the most complex bonus mechanisms around, with one feature directly affecting the next.

Cascading symbols

The symbols in a winning pay-line are removed and replaced with the symbol directly above them or by new symbols if they’re on the top row.

Money boost

When a cannonball symbol appears, it shoots the mystery symbols with the white lines and transforms them into one of the paying symbols or coins for cash awards.

Cascade tracker

The cascade tracker to the left of the reel set has three arrows plus the Bonus, Mega, and Epic levels.

Four or more cascades take you to Bonus Island, which gives you one choice from 20 chests that contain cash awards or free spins. If you reach the Mega level, you’ll choose from 20 enhanced chests, and the Epic level has 10 chests that only contain free spins.

Bonus Island

You’re first asked to choose a chest with unknown contents. From there, you eliminate the other chests to reveal their rewards three at a time.

Cash award offer: You’re intermittently given offers to trade your chosen chest for a cash amount that’s based on the value of the remaining displayed possible rewards. Once you’ve accepted the offer, you go to another screen for a chance to trade your cash offer for free spins.

Free spins offer: You can choose to keep the cash reward or trade it to spin a wheel for a chance for free spins. If you choose to keep the cash award, the feature ends. If you spin the wheel, you’re awarded free spins if the needle lands in the green areas.

Free spins

You return to the reel set and start with a 1x multiplier that increases with each cascade. The amount the multiplier can reach has no limit.

Bonus buy

You can pay a flat rate to go directly to one of the three bonus levels.

We would give the bonus round a higher rating if the instructions were clearer.

Bonus Island graphics and visuals (Rating of 3.5/5)

The game is set against a background that depicts a sandy beach with lazy waves gently lapping the shore. In addition to the typical card symbols, the higher-paying symbols are a spyglass, anchor, musket, cutlass, treasure map, and pirate. The reel set is rustic, with reel positions made from wood planks and metal. Although the graphics are decent, they look more like cartoons than the artistic, detailed graphics found on other modern games. Regardless, the visuals fit the theme and add to the overall game experience.

Bonus Island gameplay (Rating of 3.5/5)

Bonus Island is fairly complicated and takes some time to understand how everything works. The game tells you what to do but doesn’t really explain why you’re doing it. For this reason, you have to go through the bonus a number of times and see what happens if you reject or accept offers at different levels to understand the consequences. Once you’ve figured it all out, it’s a lot of fun to play, especially the bonus round.

Overall rating for Bonus Island by Inspired Gaming (Rating of 3.5/5)

Bonus Island is feature-packed, exciting to play, and an overall fun slot. While the graphics could be improved and it’s a shame you can lose your bonus winnings by making a risky choice with the offers, the free spins round is thrilling once you get to it due to the progressive multipliers. Give Bonus Island a try and see if you can master the bonus-offer strategy. Weighing out the pros and cons, we give Bonus Island a rating of 3.5/5.
