Hot Gems Xtreme Slot Game Overview

The game has 6 reels, 4 rows and a minimum of 4,096 ways-to-win. Bets range from £0.20 up to £5 per spin online on Wizard Slots casino. 

The design of the slot is pleasant. The player is taken to a mine full of small railroads, wooden ladders, and gemstones. There is an American feel to the music, particularly if the Free Games feature is activated; there it goes completely, hillbilly. Similarly, the graphics and the backing track are properly created and fit this slot’s theme well. On the whole, the design is awesome!

You can find 8 lower-value jewel symbols, a pickaxe, a lamp, and a cart filled with stones. The highest-paying symbol is the grizzly-type miner. If a combination of 6 matching symbols land, you can win up to 70x your wager. 

The wild is the diamond, and it can replace all non-special symbols. There are also ‘Bonus’ and TNT symbols that can potentially activate some good add-ons.

Several features are offered in the game, including the Way Boost game mechanic that can add extra rows into the gameplay, which can boost the number of potential winning ways.

Watch out for flaming ?s that are mystery symbols, and sticks of TNT that can activate exploding reels. There are also colossal symbols and a free spins bonus feature.

Growing Reels feature

This feature can be activated if you land a win. Then, an explosion occurs. The successful symbols are removed from the reels, and new symbols come in to substitute them. These explosions can continue so long as new wins continue to form.

Also, every win unlocks an additional row of symbols. This consequently can boost the total number of ways to form a winning combination. If you hit a winning streak and extend the grid to its full 8-row height, you can get up to 262,144 ways to form a win:

Number of Rows


Number of Ways to Win



4,096 ways to win



15,625 ways to win



46,656 ways to win



117,649 ways to win



262,144 ways to win

The reels can return to their original 6 reels, 4 rows, and up to 4,096 ways to win size if you do not land a win.

TNT Symbol 

If a TNT symbol lands, it can stay on the reels until after any potential wins have been paid out, or it can result in a collapse, and no wins are awarded. The TNT symbol can then change into a wild. Next, every standard symbol around it can explode and a new row can be added.

Big Symbols 

All the standard symbols in the game can look like single, 2×2 or 3×3 Big Symbols. If the Big Symbols are visible, they can fall down to the bottom side of the grid and can take out every standard symbol on their way.

Walking Mystery Symbols

The Waking Mystery symbol is the flaming ? symbol. If one of these is activated, it can move to a random position, transforming any symbols it walks over into additional Mystery Symbols. When the movement halts, the Mystery Symbols all change to a standard symbol that is present on reel 1. However, it cannot transform wild, TNT or bonus symbols.

Free Spins Bonus Feature

The bonus symbol is the wooden gate. If 3 or more wooden gate symbols land on any position on the reels in the same spin, it will activate this feature. The greater the number of bonus symbols, the greater number of opening free spins you can receive:

  • 3 Bonus Symbols – 10 free spins
  • 4 Bonus Symbols – 12 free spins
  • 5 Bonus Symbols – 18 free spins
  • 6 Bonus Symbols – 25 free spins

Every time a reel falls or a TNT explosion happens, 1 additional row can be attached. Distinct from the base game, this may not return to the original grid arrangement after a winless fall. The extra row can remain triggered all the way through the bonus round. If you manage to land more wins, it can lead to more extra rows - up to an 8-row max. This results in up to 262,144 ways to potentially win.

If 3 more Bonus symbols land, it will add extra 3 free spins to your total. You can also potentially land Big symbols and Walking Mystery symbols in the free spins round. Lastly, there is no limit on the total number of extra free spins you can possibly win.

Hot Gems Xtreme RTP

Return To Player (RTP): 95.81%

The RTP is a theoretical value and is shown as a percentage. It’s used to describe the percentage of money wagered a particular casino game may pay back to players over a certain period of time.

For example, if a game had a RTP of 92%, in theory, this would mean that for every £100 wagered, the game could return £92 back to players in potential winnings. However, it is important to note that winnings are completely random, and players are not guaranteed to receive this.

Our Thoughts

The Hot Gems Xtreme slot offers up to a maximum of 262,144 ways-to-win, which is significantly higher than most Megaways slots that typically only offer 117,649 win ways. The Growing Reels Feature works similarly to an Avalanche or Cascading Reels feature, and if you manage to hit a winning streak, the grid can expand. Unlike most other slots, this can occur during both the base game and the free games bonus round.

It also offers multiple special symbols, including Big Symbols and Walking Mystery Symbols. The main bonus game can trigger up to a staggering 25 free spins with the potential for re-triggers!

And let’s not forget to mention the high RTP rate of 95.81% and a top potential prize of up to 10,000x your wager!

All of this, along with a fun and entertaining mining theme, are our reasons for giving the Hot Gems Extreme: Ways Boost slot a 9/10 rating, yeehaw!
