Forge of Gems Slot Review

The Forge of Gems slot was created by Play‘n GO the software developer, and is played on a 5×3 reel. It’s one of the casinos online slots with dynamic PayWays, which means that your paylines change as you go. You start with 243 ways to win, which could increase up to 36,288.

To play this steampunk/gemstone themed slot, you have to place your bet between £0.10 minimum to £100 maximum. The Forge of Gems slot is the 4th part of a gemstone slot series from Play’n GO, which started with Perfect Gems, followed by Frozen Gems, and then Prism of Gems. 

When playing the Forge of Gems slot online, look out for the Cascades feature because that is where the likelihood of unlocking the potential max win of up to  20,000x your stake could occur.

Theme and Graphics

The Forge of Gems slot by Play’n GO is made around the medieval/gemstone theme. Everything about this slot has that icy feeling, which ties perfectly with gemstones. But, the background has a golden lit furnace-like structure that was popular in the medieval times.

You could surmise that the gemstones were formed in the furnaces. The A, Q, J, K and 10 royals are made of flat steel and are the lower value symbols. The highest paying symbols are the green, blue, orange, and pink gemstones. 

How to Play the Forge of Gems Slot

The Forge of Gems slot is created using HTML5 technology, which means that it is compatible with mobile devices such as iPhones and Android devices. 

To begin playing, you have to set your bet using the long panel with arrows on either end at the bottom of the reels. You can place your wager between £0.10 to £100.

Once you are satisfied with your bet, you can hit the Spin button. You have to land 3 or more matching symbols on consecutive reels to form a winning combination, starting from the first reel. 

The gems are the higher paying symbols compared to the royals. For example, if you land 5 matching gemstones along an active payline, you could potentially win up to 1x your stake. On the other hand, 5 matching royals could potentially award you up to 0.5x times your stake. 

The diamond wilds will substitute for any symbol, except the scatter, to form a winning combination and could award you up to 3x your stake if you land 5 or more. In addition, the red jewel scatter symbol triggers one of the 3 bonus features, the Gembox feature.

Forge of Gems Bonus features

The Forge of Gems online slot has 3 bonus features: cascades, the Forge Reel with its range of modifiers, and free spins. The cascades activate the Forge Reel, which in turn produces special symbols.

With these, you could get wild reels and rows, split symbols that increase your chances of winning, and multipliers that could increase the value of your potential winnings. For example, you could win up to 20 free spins through the Gembox feature. 

The richer the reels with diamond wilds and gemstones, the more opportunities for potential big wins.


The Cascades feature is triggered when you land a winning combination. The winning symbols are then removed and the gaps they left are filled through a cascading motion.

This feature provides the opportunity for multiple wins from a single spin and it can continue endlessly, as long as you keep forming winning combinations. 

Forge Reel

The cascades activate the Forge Reel feature. Every spin with the cascading mechanic, the Forge Reel, the horizontal reel on top of the grid, slides in new special symbols with multipliers. When the Forge Reel feature is active, any of the following could happen:

  • Multiplier symbol – This will increase your win value by +1, but it will reset after every winning round.
  • Vertical wilds – These will turn all the symbols on the same reels into wilds, except for scatter symbols.
  • Horizontal wilds – Activating the horizontal wilds will convert all matching symbols on the same row into wilds.
  • Vertical splitter -This feature will split your matching symbols on the same reels into two pieces, activating more win ways by expanding the reels.
  • Horizontal splitter – This would be a wild and will split all symbols into two, with the exception of scatters.
  • Blank symbol – This is just an empty symbol with no particular action, and it is removed through the cascade feature. 

These parts of the Forge Reel can help you form more win ways and potentially more winning combinations. The multipliers could even go up to 37x your stake! If you’re lucky, the reels could be arranged with 9, 9, 8, 8 and 7 symbols (in any order) to give you up to 36,288 ways to win in total. 

That’s why the Forge of Gems slot is part of the Dynamic PayWays games. 

Gembox Feature

The Gembox Feature is activated when 3 jewel scatter symbols land on the reels during the Cascading feature. The Gembox Feature then activates either a spin leading to an instant cash prize or the bonus free spins round.

Free Spins Feature

As part of the bonus round, the forge reel is free of blank symbols, and a multiplier symbol will always appear on the forge reel during the free spins. If you have accrued multipliers while playing the base game, they will be carried over to the bonus round, and the multipliers will never reset.

As we have mentioned, 3 or more jewel scatters will activate free spins mode or a prize. 

  • 3 scatter symbols will award either 8 or 10 free spins or up to 20x your stake.
  • 4 scatters will award either up to 30x your stake or 10 to 15 free spins.
  • 5 scatters will award either up to 40x your stake or 10 to 20 free spins.

Forge of Gems Slot Review Summary

The Forge of Gems slot is considered the hottest game at the moment. In the reels, you will find unique symbols that will enhance the grid by creating splitting symbols, offering the chance to form unique symbol combinations.
