It's been a few weeks since a decent grid slot came onto my radar, so I'm looking forward to digging down and seeing what Gemstone Mine has to offer. Free spins, hidden multipliers and a decent max win should be enough to spur me on as I chip away at this latest creation from Stakelogic.
This grid slot uses a Cluster Pays mechanic and this means no win lines. Instead, you'll need groups of matching symbols to be joined horizontally or vertically with a five-strong combo being the minimum.
The top paying symbol in this scenario pays you 0.6x. But never fear as these payouts get bigger as the combo grows. The lowest paying gem will award you 15x for a group of 15+ symbols, but the most powerful is worth 150x.
Winning symbols disappear from the grid with new ones making their way into place. This sequence of events can produce several wins if everything keeps falling in the right place. Speaking of the right place, where you want these combos to land is along the edges of the grid. Behind these blocks that fence in the game area are multipliers of up to 500x.
The first winning combo that lands along the edge will partly remove the block and reveal a section of the multiplier. New symbols drop down and if another win takes place there, the multiplier is yours.
After the wins receive their multiplier figure, there's space for new symbols to drop down into the multiplier slot as well. In effect, the size of this grid ebbs and flows with your winning sequences. When a spin doesn't produce a win, the multiplier resets and the grid goes back to its normal format.
The dynamite sticks are scatter symbols and between 4 and 6 of these will award you 10 to 30 free spins. You can get extra free spins during the bonus round when more bonus symbols land in place.
Multipliers continue to appear as you land wins along the edge of the grid and the great news is that the multipliers are now progressive and don't reset when losing spins occur. The grid remains open for additional symbols to land where multipliers once were.
Players outside the UK might have the option to buy directly into the free spins game at the cost of 100x. Alternatively, you can pay 250x to get the super bonus. You'll get more free spins and all of the multiplier blocks are already partially open, so just one win along the edge is needed to bring the multiplier into play.
The outer edges of the grid are solid blocks, but behind them awaits a multiplier. Land a winning combo next to a block and the multiplier partly reveals - the second time brings the multiplier of up to 500x into play. The multiplier space is also available for extra symbols to drop in.
Up to 30 free spins can appear, depending on the number of Scatters - you can also get more during the bonus. Multipliers are now progressive and the blocked positions won’t reset after a losing spin.
To see some fantastic wins, you will need those winning clusters to grow as big as possible. I was lucky enough to have them land and create a prolonged sequence whilst also triggering the multipliers along the edges. If you can manage a decent run as I did, the payouts are pretty splendid! I witnessed over 100x during one winning sequence. The free spins bonus will add to your balance thanks to the persistent multiplier figure and it could help you towards the 7,500x max win. Keep an eye on your bankroll as the high volatility will mean a run of spins without a win and then a good payout every so often. The RTP it's just under 96%.
This Gemstone Mine is deep underground so don't expect any bright lights and wide open spaces. Naturally, valuable gems are scattered all around and the symbols represent the same. I tried this game out on my Android device and even on a smaller mobile screen, I was pleased with the results. The sound effects are fairly standard and the soundtrack builds a suitable amount of tension to keep you gripped.
Gemstone Mine approaches multipliers and expanding reels with a little ingenuity that many fans are going to like. It's a shame that you have to hit the blocks twice to bring the multipliers into play but you can't have everything! There's a good chance that some players will get to that max payout thanks to the progressive multiplier figure during the bonus game and some decent wins available with large gem clusters. If you're new to grid slots, this is a great place to start and even if you're not, there's still more than enough here to keep you satisfied.
