Mine Island 2

Mine Island 2 Slot Review

A kangaroo in a Hawaiian shirt waits on a wooden platform while sea mines drift across an orange sunset sea and a volcano smoulders on the horizon. Mine Island 2, a crash game from SmartSoft Gaming, makes a bolder promise than almost anything it shares a lobby with: 98% back on every round, no strings attached to which volatility you pick.

It runs at 98% RTP across every volatility setting, with stakes from 0.10 to 1,000.00 and a maximum coefficient of 10,000x the bet. Two additions to the classic Mine Island mechanic, a Boost that inflates the remaining ladder and a Portal that can rescue a falling kangaroo, give this sequel its own character. Both are doing real work on a ladder this steep.

Jumping the Islands

Mine Island 2 is a single-player crash game rather than a reel spinner. There are no symbols and no paylines; instead you guide a kangaroo as it jumps from one floating island to the next, and every island you land on carries a fixed winning multiplier. The further you climb, the higher the multiplier, and the greater the risk that an island crumbles before you cash out.

A round runs in five steps, and none of them takes long to learn:

• Choose a volatility: Easy, Medium or Hard, which sets the multiplier ladder and the round’s risk
• Set your bet with the plus and minus buttons
• Press Jump to send the kangaroo to the next island and lock in that step’s multiplier
• Keep jumping, or press Collect to secure your winnings
• Take the outcome: collected wins are credited, then you can replay

Your win is always your bet multiplied by the current island’s coefficient. Collect works at any stage and ends the round on the spot. It’s the one button that matters, and the whole game is built around when you choose to press it.

There’s a soft landing at the start. The very first island never cracks, never drops the kangaroo and never triggers a Portal event, so the opening jumps carry no risk at all. The smallest multiplier sits right there, which means a safe Collect is available from the very first decision you make.

The ladder climbs from there, with ten winning steps in every volatility, each carrying its own fixed base multiplier. Replaying is instant: once a round ends, whether through a Collect or a fall, the next one starts from the first island again with whatever volatility and stake you’ve set.

The Boost

The Boost is the main new feature layered onto the classic Mine Island mechanic. After certain jumps, one or more islands can be awarded a Boost multiplier, and from that island onward every remaining multiplier on the ladder is multiplied by the Boost value.

How it works:

• The Boost value is random between 1.5x and 2.0x, in steps of 0.1
• It applies to all remaining multipliers from the island where it lands onward
• Each Boosted result is rounded down to one decimal place
• A round can contain zero, one or two Boosts

The rounding always works against you, never for you. Any Boosted value that works out past the first decimal is cut back to it, so the fraction of a multiplier you’d have gained on a fair round quietly disappears. It’s a small shave on each value, and on a ladder this steep it can add up.

The Boost matters most at the top of the ladder. Hard volatility’s base ceiling is 2,500x, but with Boosts stacked on the top steps the maximum coefficient rises to 10,000x the bet.

A Boost landing late in a Hard run changes the arithmetic of every jump that follows it, because the values still ahead of you have all been lifted before you decide whether to keep going. Two Boosts in one round is the best case the format allows, and it’s the only route to that top coefficient.

The Portal

At random steps you can land on a cracked island. It starts breaking apart the moment the kangaroo arrives, though the jump itself survives. Sometimes the island collapses completely and the kangaroo falls towards the water, taking your accumulated multiplier with it.

The Portal is the second chance. At the last moment it can appear, catch the falling kangaroo and return it to the same island it fell from, so the multiplier you thought you’d lost is preserved and the round continues.

It’s a rescue with no conditions attached: the island is restored, and the choice to jump or collect comes straight back to you. Not every fall gets rescued, and a collapsed island without a Portal ends the round with nothing.

That’s the mechanic in full, and it colours every jump past the first island. The further you climb, the more a fall would cost and the less you can do about it.

Volatility Levels

Before a round begins, you choose Easy, Medium or Hard. This isn’t a settings afterthought; it’s the single biggest decision you make, because it sets the multiplier ladder and how risky the round plays.

Each level is its own ten-step ladder with its own set of base multipliers, so Easy and Hard are genuinely different rounds rather than the same one wearing a different label. Lower volatility means smaller top prizes but reached more often; higher volatility means rarer but far larger top prizes, with Hard’s ladder running all the way to that Boosted 10,000x ceiling.

The return doesn’t move: the RTP is 98% whichever level you pick, so the choice is purely about the shape of the ride.

That 98% figure deserves a moment, because it’s high. Most online slots sit in the mid-96s, and crash games live or die on their return. On a game where the house edge is this thin, the volatility choice is where your money’s experience is actually decided.

Our Honest Verdict

Overall Rating: 7.8/10

Playing this is a series of ten-second dramas in a lovely sunset: jump, hold your nerve, and decide whether the multiplier in front of you is enough. The reason to pick it over any other crash game is that it hands you the risk dial yourself, and then quietly returns 98% however you set it. That’s a rare combination, and the kangaroo makes it easier to like than it needs to be.

The Boost is the strongest thing here, because a late one genuinely changes what the rest of a run is worth rather than just decorating it. The weakest is the emptiness between rounds: nothing carries over, nothing builds, and after twenty minutes you’ve seen every screen the game owns.

This suits players who enjoy the cash-out decision for its own sake and don’t need reels or bonus rounds to feel they’ve had a game. Anyone who plays slots to unlock things will find these islands bare. For the rest, the sea’s warm and the edge is thin, which is about as good as this format gets.

• How does the Boost work in Mine Island 2?

  After certain jumps, an island can be awarded a Boost multiplier of between 1.5x and 2.0x. From that island onward, all remaining step multipliers are multiplied by the Boost value, with results rounded down to one decimal place. A round can contain zero, one or two Boosts.
• What does the Portal do in Mine Island 2?

  If a cracked island collapses and the kangaroo falls, a Portal can appear at the last moment and rescue it, returning it to the same island it fell from. Your multiplier is preserved and the round continues. Not every fall is rescued, though.
• Is the first island in Mine Island 2 safe?

  Yes. Cracked islands, falls and Portal events only become possible once you’ve moved past the first island, so your opening jumps can’t end the round. The smallest multiplier sits on that first step, so a safe Collect is there from the start.
