Home » Slots » Hot Gems Xtreme ™

The paylines of the online casino game are 4096, and there are 4 rows to it as well as 6 reels, which is why there are possible ways of winning for up to two hundred and sixty two thousand one hundred and forty four. The variance level is high while Playtech states that the RTP is 95.81 per cent. It’s a follow-up to Hot Gems, which occurs in a diamond mine located in Old West. Some of its features include scatters, wilds and free spins.


After eight years and so many Playtech free slots, this company went public. Then it released the new enhanced version of Hot Gems. It still has the free spins bonus round from the old game but also adds some extra features. Maybe we will see another successful title update like Playtech’s Great Blue slot one day.

A 6-reel, 4-column grid and a total of 4096 pay lines are the main features of Hot Gems Xtreme. Bet amounts range from a minimum of 0.20 to a maximum of 240.00.

Theme, graphics and soundtrack

Hot Gems, I have to say, has better graphics than Hot Gems. Its mine is much more detailed and the animation used in it is also smarter. Although it still has lots of noisy sound effects and a soundtrack that is stuck in banjo-land, this makes the game generally nice looking.

Hot Gems Xtreme bonus features

Growing Reels Feature

Growing Reels feature works throughout the main game and Free Games feature. The basic size of a grid is 4×6. Following every winning stage, grid sizes increase by one row and the ways through which one can win are enhanced. When winning symbols pay out, they cause non-winning symbols above to fall off and be replaced with new ones from above.

TNT Symbol

Every time the TNT symbol lands, it stays on the reels after all wins have been paid and a collapse happens with no new win. Besides Wild, Bonus, Big and Walking Mystery symbols, adjacent symbols to TN symbols are converted into wilds and they will explode soon enough. After the explosion of TNT symbol in the reel, it will grow as new signs fall down giving more chances for winning.

Big Symbols

All symbols except Wild, Bonus, TNT, and Walking Mystery can appear as 2×2 or 3×3 big symbols in this game. Whenever a large symbol lands on the reels, it falls and destroys every symbol underneath except Wild, Bonus, TNT, Walking Mystery or ones of equal dimensions.

Walking Mystery Symbols

There are no TNT symbols on the reels, a collapse results in no new wins, and it stays on the reels after all wins are paid whenever the Walking Mystery symbol lands.

Once the walking mystery symbol has been triggered, it will move and stop on a random position. After the walking mystery symbol finishes its movement, all other mystery symbols turn into any of the reel one’s symbols apart from Wilds, TNT or Bonus.

All Mystery symbols will turn into a random symbol, except for Wild, TNT or Bonus symbol in case a Walking Mystery sign lands on reel 1 or moves to it. In case the Walking Mystery sign goes over a big one it immediately turns all the big symbol into a mystery one.

Free Games

Playing with the slot machine, when you land on three or more symbols that say bonus anywhere on the reels, it will automatically unlock a free game. This is how bonus works in this game: if you get 3 bonuses, you are going to obtain ten free games; if you get 4 bonuses, you will have twelve; for five of them, there will be eighteen and so on.

Hot Gems Xtreme review: our verdict

Hot Gems Xtreme takes Hot Gems up a notch or two in terms of complexity. This means: instead of getting tired quickly, you will be more involved. The Walking Mystery Symbol is very fascinating to the players. It’s a bit of laugh.
