Released: 20 Nov 2020

Sparkly gems, picks, lanterns and lots of dynamite is what it takes for Playtech's WaysBoost system slot to raise the roof of the mine. Players can land multiple reel modifiers and a free spins bonus towards the game's big payout potential. It all takes place on six reels and initial 4096 ways to win that can rise many times that number. This game is sequel to the rather mundane-looking Hot Gems slot, which was hot to play nevertheless.

Hot Gems Extreme Slot Online

Playtech has made a mighty mining game come to live with the help of that company's original payout system - WaysBoost. The game takes place inside a cavernous mine that hides precious, shiny gems that are worth cash prizes. 

About Hot Gems Extreme Slot

Perhaps Hot Gems Extreme slot isn't the only game with a mining theme released in 2020 but it surely is among the top ones. This is due to the WaysBoost system which starts each spin with 4096 potential ways to win. 

A thrilling lining in the gameplay is made possible by reel modifiers that can blast away symbols, colossal symbols, expanding reels and rows, and more. Overall, Playtech has made a game that is fun to play so we'll give it a full review. 

Design, Symbols and Graphics 

The layout of symbols and the events on the reel set can combine to create a reel adventure that is in constant motion. Enjoying the game as it had been intended may warrant trying out the autoplay feature because that enables you to play Hot Gems Extreme hands-free while getting a good look at the shifting vaults of this slot mine. 

There is some animation as part of the action and it involves the reel modifiers rather than the symbols themselves. Speaking of, the paytable consists of various gems and the tools of the mining trade, such as picks, lanterns, wagons and the character who does the diggin' - the foreman. 

In terms of payouts, Hot Gems Extreme slots has a wide range of values. The gems are low-paying symbols that can bring in between 1x and 12x multiplied by the bet stake. The high-paying category of symbols can pay between 2x and 75x. These values are for winning outcomes between three and six symbols. The only exception is for the foreman (the miner) whose symbol can pay for two of a kind also. 

RTP, Variance and Payouts for Hot Gems Extreme Slot

Playtech has equipped their production with a value for the RTP of 95.81%. This is only slightly below the 96.00% average which has been the industry's standard for online slots, however, 2020 seems to be a turning point where RTP values are lower but the mathematical models seem to be more inclined to generate more frequent payouts. 

Our experience with Hot Gems Extreme and its WaysBoost system has had us pretty surprised with the payout rate. Although we don't know the variance level, it feels like the game shifts between the lower end of medium and the first footstep into high. 

Players who are into online slots for the thrill of playing high variance, high-payout game will feel at home here because Hot Gems Xtreme has 10,000x as its maximum potential that can occur from a single spin.

Gameplay and Features on Hot Gems Extreme Slots

A feature of itself is the expanding of the reel set which can occur with successive wins. It can all start from a single win outcome because the game continues to add rows and symbols on the reels with subsequent winning outcomes. 

Few features can increase your chances for getting the most out of the WaysBoost system. These are the dynamite, the Walking Mystery, the colossal symbols and the free spins bonus.


A dynamite symbol can land at random anywhere on the reels and turn into a wild symbol that causes multiple symbols to explode and become removed from the playing field. 

Walking Mystery

This modifier comes in the shape of a flame that moves about the reel set and spreads symbol positions. The number of moves is random, but the fire can spread pretty far and wide. When it's ready to settle, the affected positions will turn into one of the regular paying symbols of the same kind.

Colossal Symbols

The big symbols are not only primed to link with a greater number of matching symbols, but they can also crush the smaller symbols that are below them. Regular symbols can come on in 2x2 and 3x3 size. 

Free Spins Bonus

The bonus symbol is represented by a shuttered mine vault and it can land on three, four, five, six or more positions on the same spin. The number of free spins is as follows: 10, 12, 18 and 25. Each winning outcome during the free spins raises the so-called Safety Level higher, which means the rows up to that level will remain active. The Hot Gems Extreme bonus feature can retrigger with three or more symbols. 

Hot Gems Extreme on Mobile

Playtech makes mobile-friendly games and this is true for the game at hand. Players can see the full marvel of this mining adventure on iOS and Android devices, both mobile and tablets, just make sure that you keep the device in vertical mode in order to get a full view of the rising rows. 

Is there a Jackpot on Hot Gems Extreme 

Players who are looking for an instant jackpot win aren't going to find it in this game. Instead, there is a rather sizable win maximum that can occur in the free spins bonus by way of multiple retriggering events and lots and lots of reel modifiers that influence high-paying symbol wins. 

Other Playtech Slots 

The company and all of its partner studios is prolific when it comes to releasing games. Sure, they have a lot of releases but most are rather decent to good and some are great, such as the present game. We'd like to point out a few other exciting titles that were released in 2020: Rubik's Cube slot, Legacy of the Tiger and the Infinity Dragon slot

Slotswise Verdict

Our impressions from the game are quite positive. In a few words - Hot Gems is entertaining, has a good ratio between payouts and win frequency and has amazing extra events, such as the reel modifiers, that can trigger quite frequently. Overall, it's one of the best Playtech games in a while and the maximum 262,144 ways to win are just part of the whole package.
