Hot Gems has a Collapsing Reels feature that remains active throughout the base game. Every time you secure a winning payline, the symbols in that line will disappear and new ones will fall into place from above. If these new symbols form another winning payline, the process will repeat and will keep repeating until there are no more wins.

The Hot Gems Logo plays an important role in this feature as you only need two of them to trigger a win. You will also want to keep your eyes peeled for the symbol of the Miner, who is glaring excitedly at a nugget of gold. You will need three of these symbols to trigger a win, but if five of them appear then a payout of 5,000x will trigger.

Play for Fun

If you’re new to Collapsing Reels or want to try your hand at this slot game’s main feature, take a spin in demo mode. You will need to sign up for a Slots Heaven account, but you don’t need to have any money in that account. This mode is offered on many of our slot games and is available to all players.

Play for Real Money

Once you’re ready to take a real money spin, simply visit the Cashier, make a deposit using a multitude of secure payment methods, and confirm your amount. It should only take a few seconds, after which you’ll be ready to return to this page and start playing for real money.


The Miner symbol returns the biggest payout, going as high as 5,000x for a full payline. This means that a $/€1 payline bet will return a win of $/€5,000. And that’s just one spin! With the introduction of the Collapsing Reels feature and the free games, it’s possible to go much higher than this.


  • Coin Sizes: Alter the “Line Bet” amount to change how much you wager per spin, with the minimum going as low as $/€0.20 per spin and the maximum as high as $/€500. You can’t adjust the paylines so you will always play the full 25.

The big golden free games symbol triggers a total of 15 free games when it appears on the first, third, and fifth reels. The Collapsing Reels feature remains active during all of these 5 spins, and there is also a rolling multiplier. Every time the symbols explode, the multiplier jumps by 1x and it continues to increase in this manner until the wins stop or the multiplier reaches 5x.

When you take a new spin, the multiplier resets and will only grow again if there is another winning payline. The Hot Gems logo and the free games logo can also form part of a winning symbol during the feature and will explode when they do so.
