Cascading Wins
Like many cluster pays slots, Gemstone Mine is a cascading wins game. That means after each winning spin, winning symbols are removed from the grid, remaining symbols and new ones from above drop down to fill the spaces. If more clusters form then the process repeats until no more wins are triggered.
Multiplier Symbols Up To 500x
Gemstone Mine brings multipliers into play using an interesting mechanic. The multiplier values are displayed behind stone blocks on reels 1 and 8 and rows 1 and 2 at the bottom of the grid).
To unlock the power of the multipliers, a cluster must form adjacent to it. First time round this will partially reveal the multiplier. The second time a cluster forms adjacent to the multiplier, it is completely revealed and its value is applied to the total win for that spin.
If more than one multiplier is revealed during a spin and subsequent cascades then their values are added together before being applied to the win.
But your multipliers don’t last – they are covered over again once the spin is completed.
And finally, you’ll notice that once a multiplier is revealed its value is stored to the left of the grid, meaning the space it vacated is now free for pay symbols to land on in subsequent tumbles. Effectively, the grid is growing in size!
Free Spins Bonus Round
Look out for the bonus symbols represented by the dynamite sticks. These are like scatters – they trigger the free spins round as follows:
- 4 Bonus Symbols – 10 free spins
- 5 Bonus Symbols – 15 free spins
- 6 Bonus Symbols – 30 free spins
NOTE: You can extend the round by a further 5 spins by landing 3 more scatters at any time during a free spin and subsequent cascades.
Now the game changes in your favour. Because during the round ALL multipliers are added to a global win multiplier which will be applied to your total free spins win at the end of the feature. That gives you potential to build a big, big multiplier!
And … after multipliers are revealed on the outer reels and bottom rows these positions do NOT re-set between spins, so your grid just keeps growing, giving you more chances to create bigger clusters.
Super Stake
With Super Stake you can add 0.25x to each bet you make to increase the odds of triggering the free spins round by adding more bonus symbols to the reels.
