Theme – fire up the furnace

Theme: Medieval/Gemstone

High Value Symbol: Blue Gemstone

Compatibility: Mobile, Tablet, Desktop

forge-of-gems-slot-base-game

Part of Play ‘n GO’s Gem series, the Forge of Gems series has a medieval/gemstone theme. With a furnace forming the backdrop, it has an olde worlde feel to it visually. The story is these precious gems have been forged by the intense heart of the furnace. Visually reminiscent of IGT’s Da Vinci Diamonds, it looks like the game took place during the Renaissance period.

Symbols on the reels include A, K, Q, J and 10 royals. The higher value symbols are represented by gemstones (blue, orange, green and pink). The blue gemstone is the best paying symbol with 3, 4 or 5 in combination paying 0.3, 0.6 or 1 x your total stake.

The diamond is the wild symbol and substitutes for all symbols above. Landing 5 in sequence will result in a 5 x bet award. There are also red flower jewel scatter and Forge Reel symbols which are described in more detail below.

Forge of Gems Mobile

forge-of-gems-mobile-slot

Created using HTML5 technology, Play ‘n GO allow for users to play Forge of Gems on mobile, laptop, PC and tablet devices. Perfectly suitable for play on mobile devices including iPhones and Androids, I would personally opt for a desktop device, especially when you can create up to 36,288 ways to win.

Forge of Gems Bonus Features

The Forge of Gems slot has 3 bonus features. Cascades lead to the Forge Reel being activated which in turn brings special symbols into play. These can give you wild reels and rows, split symbols for more ways to win and increase the multiplier. This applies in the Gembox feature where up to 20 free spins can be won. With richer reels, this can lead to red hot wins.

Cascades feature

When you land a winning combination, the Cascades feature is triggered. Winning symbols are removed and the Forge Reel is then active (the top horizontal reel). Symbols from the Forge Reel cascade with empty positions refilled on all reels to potentially create new winning combinations. The process repeats itself as long as new wins are created.

Forge Reel feature

forge-of-gems-slot-forge-reel-feature

When the Forge Reel is active, symbols appearing the top horizontal reel come into play. Known as the Forge Reel feature, here’s what to expect:

Vertical Wild Turns all symbols (except scatter) into wilds on the reel
Horizontal Wild Turns all matching symbols on the row into wilds
Vertical Splitter Splits matching symbols on the reel giving you more ways to win
Horizontal Splitter Splits symbols (except scatter) on a row and is also wild
Multiplier Increases the multiplier by 1 (it resets between each base game spin)
Blank This is removed when cascading

The multiplier can increase up to 37x if you’re lucky. The vertical and horizontal splitter symbols will lead to more symbols appearing on the reels. This will give you more ways to win. It’s possible to have the 5 reels displayed 9, 9, 8, 8 and 7 symbols (in any order) to give you 36,288 ways to win in total. This is known as Dynamic Payways:

9x9x7x8x8 = 36,288 ways to win

Gembox feature

forge-of-gems-slot-gembox-feature

Look out for the red flower jewel scatter which can appear on all 5 reels or cascade from the Forge Reel. 3 or more scatters will trigger the Gembox feature. Here, there are instant prizes and/or free spins:

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

Unlike the base game, there are no blanks on the Forge Reel. Furthermore, a multiplier symbol is always guaranteed. If you trigger the feature with a multiplier, it will be carried over into the free spins. The multiplier can increase infinitely but no additional free spins can be won.

Originality








The 3rd in the Gem series, the Forge of Gems slot is the best game so far. High action and red hot, Play ‘n GO has added more extras than in its predecessors.

Visually, it has a retro feel which will appeal to players who like certain Las Vegas classics. It’s not about that though. The key to everything is the Forge Reel which brings in various symbols into play. The Vertical and Horizontal wilds will give you wild reels or rows which is a nice additional.

You want to land the Vertical and Horizontal splitter symbols as this increases the number of symbols and ways to win. If you get enough consecutive cascades, you could benefit from 36,288 ways to win at best.

That said, the most lucrative Forge Reel symbol is the multiplier, which combined with splitter symbols and plenty of cascades will give you the best chance of achieving 20,000 x stake max wins. The multiplier can reach up to 37x.

In the free spins (Gembox feature), it’s pretty much as in the base game but any multiplier carried through will give you a leg up once you start increasing it. Furthermore, no blanks appear meaning richer reels and potentially bigger rewards.

In summary, Forge of Gems is an enhanced version of the previous Gems series slots. The max win potential is also significantly higher, 20,000 x stake, and is double that of Frozen Gems and quadruple the number in Perfect Gems. Saying that, Prism of Gems is a tad simpler but offers the biggest win potential of 30,000 x stake per spin.

If you want splitting symbols, Nolimit City have a few slots using the xSplit mechanic such as Tombstone RIP. This controversial and brutally volatile game comes with 300,000 x bet max wins.

Pros
  • 20,000 x bet max wins
  • Splitting symbols offer up to 36,288 ways to win
  • Free spins with richer reels
Cons
  • Very high volatility
