When you click the game tile and launch the game, you’ll be transported deep underground, where the stone game grid sits in a cavern filled with glittering gems, fires burning to either side and the control console sitting beneath.
When you’re ready to play, use the plus and minus buttons to first set your wager, then click the spin button to start the reels spinning. If you hit a winning spin, your payout will flash on the screen as the winning symbols explode and new ones tumble down from above.
There are two tiers of pay symbols on the grid: low-paying gemstones partially embedded in the rock and premium gems that have been fully excavated. The highest payer is the blue gemstones symbol, which offers a 150x payout for clusters of 15 or more symbols.
Bonus symbols consist of two multiplier symbols, one gold and one diamond, and a TNT scatter symbol that leads to the free spins bonus.
The cluster pays mechanic works by awarding prizes for connecting clusters of 5 or more matching pay symbols on a single spin. Symbols forming the cluster must all be identical and touching along one of their four sides.

This multi-feature slot offers plenty of opportunities to boost your wins:
A tumble sequence can be triggered any time you land a winning spin during the base game. All symbols involved in the winning cluster explode from the reels, allowing new symbols to tumble into place.
If another winning cluster is formed following a tumble, the sequence repeats.
If exploding winning symbols touch blocked positions on reels 1 and 8 or rows 7 and 8, they break some blocks away to expose hidden multiplier symbols. A second explosion will fully expose the multiplier symbol, the value of which is collected before the gem explodes to open the position for regular pay symbols.
Multiplier values can range between x2 and x500 and blocked positions reset between each base game spin.
You need 4 or more dynamite scatter symbols to trigger the game’s free spins bonus, earning free spins as follows:
You can also earn additional free spins during the bonus game by landing 3+ scatters.
During the bonus, blocked positions with multiplier symbols don’t reset between spins, and all multiplier values are collected and applied to your win total at the end of the round.
The Super Stake is an ante bet that gives you the choice of doubling your chances of triggering the free spins bonus for a fee of 0.25x the bet. The Super Stake function increases your bet size per spin but does not increase the paytable.
