How to Play

The 5-reel, 3-row playing field provides up to 36,288 ways to win, and there is also a top sliding reel that awards 5 unique modifier symbols. The game is based on the Cascading Wins mechanic, which means that winning combinations are removed from the playing field and new symbols land on empty spaces. To create a combo you need to land 3 to 5 matching symbols from left to right on 1 of the lines.

To start forging real gems you need to:

  • Load Forge of Gems at your chosen casino
  • Remember the rules and bonus features
  • Check the symbol value
  • Select a bet: from €0,10 to €100
  • Set the reels in motion by pressing the spin button!

Forge of Gems RTP and Volatility

8 
Forge of Gems is a video slot with high volatility and variable RTP.

Hopefully you can take the heat, because Forge of Gems comes with high volatility, meaning that it will be harder to land a winning combination, but the payoff will be quite good. Fortunately, there is a Cascading Wins mechanic that will help you create more prize combos.

The theoretical default return is variable, with 94.2% being the default but it can also be 84.20%, 87.20%, 91.20%, and the highest of 96.20%. Please check the actual return of the slot before playing it!

Theme

9 
When you first open the game, you can see the vault opening, and then you’re taken to the main scene. All actions take place against the background of the forge, accompanied by the appropriate and weirdly soothing sounds. It is heavily shattered and when you activate the bonus feature, a very strong red glow comes from it. In the foreground is a 5x3 iron playing field and above the playing field is a sliding gold top reel. The game looks good and gets a really epic look during the bonus features!
 

A gold-framed gem, a glowing gem, and orange, green, and pink gold gems are standard premium symbols, and the paytable also features A-10 playing card suits, which are low-paying icons.

By the way, the Gem in a golden frame is also a Wild symbol that can replace all the usual ones. The Red Jewel is a Scatter and you need 3 in the same cascading sequence to activate the Gembox feature.

Bonus Rounds & Free Spins

9 

Forge Reel

There is Forge Reel above the playing field - this is a special reel that will show special modifier symbols with each spin. You need to trigger cascades to remove the symbols below and thus make those modifiers fall on the playing field.

Here is a summary of what you should expect from modifiers:

  • Multiplier: Increases the multiplier by +1, but resets between each spin (paid spin)
  • Vertical Wilds: Turn all symbols on reel 1 wild (all but scatters)
  • Horizontal Wilds: Turns all matching symbols on row 1 into Wilds
  • Vertical Splitter: Divides all matching symbols on 1 reel into 2 parts. Thus, he expands the row and increases the number of ways to win.
  • Horizontal Splitter: Acts like a Wild and separates all symbols on the 1st row (all but Scatters)
  • Empty Symbol: Does nothing, removed when the cascade is triggered

Gembox

Once you land at least 3 Red Jewel symbols in the same cascading sequence, the slot will activate the Gembox feature. This feature awards a spin that can lead to an instant prize or a bonus round. Here is what you can get for a certain number of trigger symbols:

  • 3 Scatters: 20x prize or 8 or 10 free spins
  • 4 Scatters: 30x prize or 10 or 15 free spins
  • 5 Scatters: 40x prize or 10, 15 or 20 free spins

During the bonus round, no empty symbols appear on the special Forge Reel and 1 multiplier symbol is guaranteed to appear on the Forge reel for every free spin. Any multiplier you were able to create in the cascading trigger sequence carries over from the base game, and the multiplier never resets during the bonus round.

Max Win

9 
Forge of Gems allows you to win 20,000x the bet.
The maximum you can win here is 20,000x the bet and that's a solid max win potential for a high-risk game. The modifiers are smart enough and can work together to give you some pretty solid wins in the base game however given the low symbol values (in our humble opinion) you will likely need a Free Spins Bonus Round to unleash that massive max win potential.

Overall Rating

8.7

The visual representation of this Play'n Go slot looks cool but it also feels too cold and general. The gameplay works like a well-oiled machine when you turn on the turbo mode. The modifiers are smart and can work together to give you some pretty massive base game prizes, but you'll likely need a multiplier to make that happen since the paytable payouts are low.

Free Spins feature with a non-resettable progressive multiplier can pay up to 20,000x the bet is a big max win potential that will definitely attract high-risk players.

Slots about is my guilty pleasure, lol. I play all of them! And couldn’t pass a one from Play’n Go.
A max win of X20,000 sounds great, and I see ways to achieve such win. It’s a multiway cascading slot with additional multiplier that can be activated during both base and free spins.
The slot’s heart of the matter is vertical reel that bring wilds, multipliers, and other enhancers. The problem is that all those features don’t guarantee you massive wins from the get go. It may take time!
