Fuel for Action Review of Amber Island Slot Machine, Including Gameplay Enhancement SpinPlay Games’ Amber Island slot machine, playable at Microgaming-powered online casinos, became live in May of 2023.

The slot’s fiery/volcanic theme turns up the heat, turning random reveal lava symbols into winning combinations as you spin the reels.

Free spins with varying features and a maximum award of 5,000x the wager may be triggered by collecting gem symbols hidden within the reveal symbols with the help of the three volcanoes perched above the gameboard.

Style of Slots

Fuel for Action When not in a free spins bonus, the Amber Island online slot’s 5 reels, 4 rows, and 20 fixed paylines are expanded to 6 reels, 4 rows, and 40 fixed paylines.

The slot has a medium volatility and an RTP of 96.39%.

The slot is suitable for a broad variety of gamers because to its large betting range (0.20-$50.00 each spin).

It takes a lot of clicks to alter the stake using the + and – buttons (bottom left) that are standard across SpinPlay Games’ slots.

We discovered a tiny solution a while back, and that was to use the Autoplay menu, which can be accessed by clicking the plus sign next to the Spin button over on the right.

The total wager may be adjusted using a straightforward slider in this menu; just drag it to the correct amount and the change will be saved even after you shut the window.

Next to the Autoplay button, you’ll find Quick Spin nestled within the plus sign.

The right-most menu just offers two options, mute and payline, so we can’t silence only the music or just the sounds if we want to.

The graphics are excellent, with detailed symbols and fluid animations, but this is par for the course for slots from this developer.

Slot Functions

The feisty female symbol acts as the game’s Wild, replacing all icons save the Gem icon, and appearing stacked on any reel.

You should be prepared to encounter these regularly, despite the fact that the rewards are generally unremarkable.

The Random Reveal Lava Symbol appears often, and when it does, it reveals either a gem symbol or any other symbol in the game (with the exception of wilds).

A bonus cash reward can be won during free spins if the reveal symbol reveals a volcano symbol.

During Action BoostTM Free Spins, the corresponding volcano at the top of the gameboard will gather a gem in the appropriate color whenever the Random Reveal sign exposes one. You increase your odds of triggering an event by collecting more data. The eruption of more than one volcano can occur simultaneously.

Green Gem’s Power-Up in Action The green gem-shaped volcano on the left side of the screen activates free spins. You get 5 free spins to use in this bonus before the board size increases to a 5×6 grid with 40 fixed paylines. During this bonus round, the Volcano icon will be hot, leading to random cash payouts.

High rewards are possible in this feature if you manage to land many Wilds, which will nudge throughout the full reel. In all, this feature paid out almost 43 times the wager.

The red gem volcano in the middle of the screen activates the red gem action boost free spins bonus. You get 10 free spins to get started, and there are four progressive jackpots to win: a 10x mini, a 50x minor, a 500x major, and a 5000x mega. Each jackpot will be symbolized by a certain color of gem, and winning that jackpot will require collecting a predetermined number of that color.

To win the Mini jackpot, as seen in our screenshot, you need to gather three green gems. After a jackpot is won, the gems associated with that prize are reset to zero. Only in the Volcano Symbols will you find the jewel symbols.

Free games with a purple gem action boost are activated when the correct volcano shows up. There are a total of 5 free spins available at the start of the feature, with a multiplier of between 2x and 5x. During this bonus round, the Volcano icon might trigger additional spins.

In general, the 5x multiplier would be quite uncommon, whereas the 2x and 3x multipliers would be more common. We were awarded an extra four spins, but the feature’s total payoff was only about 26x our wager.

Multi-Gem Action Boost Free Spins: It’s possible for many gems to activate at once, awarding you with not one but two or three benefits all at once. You’ll get 10 free spins if the red gem is part of the trigger, or five if it isn’t. The multiplier function does not increase the jackpot rewards and only applies to the cash prizes and line winnings.

Here, we hit the free-spins bonus by getting the red and purple gems, which awarded us 10 free spins and an x2 multiplier on our lines. We received three further spins and hit the Mini-jackpot twice while in the bonus round. After 13 spins, the total reward was close to 40x.

When we used a green and purple gem together, we activated the multi-gem function for the second time, which resulted in an enlarged playing area and a random multiplier. The Wilds nudging throughout the bonus round and having their wins increased by the feature’s multiplier made for a potent combination. The final payoff was almost 81 times what we put in.

You may look forward to this as a possible pairing.


Action Boost Amber Island is a fantastic slot, and we enjoyed it much.

The Action Boost function, which awards free spins along with various bonuses, is proving to be very well received by players.

We were pleasantly delighted to find that the multi-gem option activated more frequently than we had anticipated.

Six of the seventeen triggers we hit were multi-gem triggers, each with its own unique set of benefits that paid out rather well for a medium-volatility slot machine.

Both Action BoostTM Amber Island and the brand new Action BoostTM Gladiator Slot can be found at Yukon Gold Casino, and we urge players to check them out.
