Action Boost Amber Island (SpinPlay Games) – Review & Demo Play

Action Boost Amber Island Slot Information

SpinPlay Games sets Action Boost Amber Island on a volcanic island with three active peaks above a 5x4 grid. It wasn’t love at first sight for me, yet the system pulled me in. The gameplay runs on 20 lines in base play, rising to 40 lines in specific features. Random Reveal symbols tie into gem collection that can spark the Action Boost Free Spins. The max win is 5,000x, volatility sits in the medium camp, and the presentation is tidy if a bit generic.

How to Play Action Boost Amber Island Slot

I hit the dark circle to spin the 5 reels with 4 rows. Tapping the plus sign opens autoplay with up to 100 rounds and a quick-play option via the lightning bolt. The chip icon sets stakes from 0.2 to 50, which covers casual spins and testing higher bets. Three lines open the paytable and audio. It’s all clean and responsive on mobile or desktop, and the layout keeps the jackpots visible above the grid.

Wins land by matching 3 or more symbols on 20 fixed paylines in the base game. The Random Reveal symbol appears on every spin, which gives each round a shot of suspense as it can flip into matching pay symbols or gems. Those gems feed the volcano meters. When I’m learning a slot, I like to start with short autoplay sets, toggle quick-play for tempo, then scale stakes once I see how often the features tease and trigger.

Symbols and Payouts in Action Boost Amber Island

The low-paying set is 9 to A, paying 0.1x to 1x for five of a kind. High-paying animal symbols step it up: Dragonfly and Lizard pay 0.25x to 2x, Frog and Toucan pay 0.25x to 2.5x, while the Jaguar tops the set at 0.5x to 5x. The lava-haired goddess is the Wild. It substitutes for all pay symbols except gems, and it can stack. Land 3 to 5 Wilds for 1x to 10x wins on a line.

The Random Reveal symbol is a dark stone with lava. In base play it reveals a matching pay symbol or a gem (green, purple, red). In features it can also reveal a Volcano. That Volcano can count as both a gem and the revealed symbol, which helps lines as well as collections. The paytable is straightforward, and the Wild being the highest payer fits the way stacked and nudging behaviour appears during specific free spin modes.

Action Boost Amber Island Bonus Features

Random Reveal symbols hit on every spin. When gems appear, they collect in the 3 volcano meters above the grid. Any collection gives a chance to trigger Action Boost Free Spins, and you can start with one, two, or all three gem features active. During features, Random Reveal can show a Volcano symbol that awards prizes or jewels and can count as both a gem and the revealed symbol. This ties the line wins and collections together in a neat loop.

Green Gem awards 5 free spins. Each reel gains 1 extra row, so the game runs on 40 lines with 6 symbols per reel. Any Wild that lands nudges to cover the reel, which is a strong look when combined with extra lines. Volcano reveals pay bonus credit prizes here, and the extra height helps those stacked Wilds land fully. Purple Gem also starts with 5 spins, and the Volcano reveals add 1–2 spins or a cash prize.

Purple Gem gives a random multiplier of 2x, 3x, or 5x on every spin that applies to line wins and Volcano prizes. Red Gem grants 10 spins. Volcano reveals can pay a cash prize or a jewel. Collect 3 green, 4 blue, 5 purple, and 6 red jewels to land Mini, Minor, Major, and Mega jackpots of 10x, 50x, 500x, and 5,000x. Trigger multiple gems at once for combined features; the multiplier won’t apply to jackpots, but it lifts everything else nicely.

RTP & Volatility in Action Boost Amber Island

The RTP clocks in at 96.39% with medium volatility and a hit frequency around 36.59%. The top prize is 5,000x, reachable through stacked Wilds, multipliers, and the jackpot path in the red feature. Stakes run from 0.2 to 50. I’d flag the presence of adjustable RTP ranges across releases, so I always check the paytable info where I play. Fixed jackpots (Mini, Minor, Major, Mega) add a clear ladder, and the 20-to-40-line shift keeps the maths model lively.
