Gemstone Mine - Review, Demo Play, Payout, Free Spins & Bonuses

Gemstone Mine slot review

Gemstone Mine is one of the slots created by game designer Stakelogic. The base game opens on a six-reel, six-row grid, but more cells on the grid can be created.

We are mining for the gems that appear as the seven standard winning symbols and pay out when clusters of at least five appear connected horizontally or vertically. When this occurs, the winning symbols are removed from the grid and replaced via an avalanche mechanism. This designer encourages us to think bigger, and this is one of the slots that allow us to do so as new opportunities open up.

Players benefit from a scatter symbol that triggers free spins when at least four land anywhere. Up to 30 free spins can be awarded and the feature can re-trigger. A win multiplier can be hidden on the first and eighth reels and the bottom two rows, with winning combinations adjacent to these blocks revealing them. Win multiplier values range from 2x to 500x and are applied to subsequent wins.

Our comprehensive Gemstone Mine slot review follows:

Theme

As the title suggests, this is another mining game. We are chiselling away at multipliers hidden behind the stone to try and increase our jewelled prizes, but the twist is that we are inside a tomb with stone blocks hiding the special symbols.

Symbols

The winning symbols are colourful precious stones mined from the stone-filled grid. There are seven colourful symbols, which can add to your balance by appearing on the six rows of reels two to seven.

Soundtrack

A tune that would not be out of place in an explorer-themed movie plays in the background.

How to win at Gemstone Mine

Gemstone Mine bonuses 

Let’s examine a few of the Gemstone Mine bonus features in more detail:

Free spins

The dynamite is the bonus symbol and when four appear anywhere on the reels, they trigger ten free spins. Five or six of these symbols award 15 and 30 free spins respectively. Five additional free spins can be won during the cascades if three or more scatters appear. During this phase, multipliers are added together and applied to the total win. Multiplier positions that have been revealed don’t reset.

Multiplier symbols

These are hidden behind reels one and eight and rows seven and eight. Adjacent wins can reveal these. The first adjacent win reveals the multiplier, while the second applies it. The revealed position then becomes available for regular symbols to land. The value of the multiplier ranges from 2x to 500x.

Max-win 7,500x

Volatility Medium

Top RTP 94%

Gemstone Mine review summary 

Here is a recap of our Gemstone Mine slot review:

Design

There are plenty of mining slots on the market, but this one has a bit of a twist. The game is set in an underground tomb, where we chip away at the structure rather than wield picks against a rockface. This makes a pleasant change.

Features

The game has the usual free spins; in addition, there are multipliers that can reach 500x.

Overall

We found the game to be an interesting change from the usual mining slots.
