Back in the early days of mining and prospecting, a man can make his fortune with an oil lamp, a pick axe and a cart. It is a far cry from today, where all you need to make a fortune is to play online slots. Hot Gems by Playtech, harks back to the days when a dark and foreboding mineshaft can reveal treasures from the earth.

Hot Gems is a 5 reel, 25 payline slot game that can be played for real money using MasterCard, Skrill account etc. Players can make wagers on these paylines that range between 0.20 and 20. The maximum possible wager is 500 in total, per spin.

This slot makes great use of its collapsing reels bonus feature to add multipliers during the free spins bonus game. A jackpot win of 5000x your line wager is available to lucky players.

The Precious Stone Collection

The Hot Gems slot symbols are related to the hardworking miner and the treasure he finds on the deep dark recesses of his mine. The miner is in fact the highest value symbol in the game, with a jackpot value of 5000x.

Next in value is his trusty oil lamp that helps him locate the glittering gems embedded in the rock face. His rusty pickaxe is the next in value symbol. Strangely enough, a mine cart filled with gems is worth less than these other two items.

The gems themselves make up the rest of the standard symbols. They have lower prizes than the other symbols but you will make combinations with them more often.

The Game Logo is Wild

The Hot Gems wild icon does exactly what it says. It will be a substitute for any of the standard symbols as long as it is on the same payline as an almost complete combination.

The wild will not substitute for the scatter or bonus symbol and it doesn’t offer any casino prizes by itself.

Stand your Ground with the Collapsing Reels

Hot Gems features a popular bonus called the Collapsing Reels feature. Players may have encountered a similar feature in other slot games.

Basically whenever you form a winning combination with matching symbols, each symbol that formed part of the combination will explode, leaving the icons above to collapse down into the empty slot.

If this collapse forms a new winning combination, you will retrigger the event. Not only does this effect look great but it can mean some big wins for the player.

Free Games and More Collapsing Reels

The Hot Gems free games feature is activated, surprisingly enough, by the free games icon. This symbol appears on reels 1, 3 and 5. As soon as you land three of these symbols in view, the free spins game will start, granting you 15 free spins.

The Hot Gems collapsing reel feature really comes into its own during the free spins game. Now, each collapsing reel trigger will add a win multiplier to the reels.

You will start the free spins round with a 1x multiplier active, but each winning combination formed by the collapsing reels will add another multiplier up to a maximum of 5x.
