Forge of Gems by Play n Go

This April Play n Go, recently granted a license to supply games in Ontario, release the fourth instalment in their Gems series. Forge of Gems follows on from Perfect Gems, Frozen Gems and Prism of Gems and viewing the game for the first time, our team at The Casino Heat can report it’s another super-cool slot from one of Sweden’s best developers.

Forge of Gems doesn’t rest on its laurels – this is a slot that takes the best bits of the previous Gems games and adds further intricate gameplay including expanding paylines, win multipliers and free spins.

But it’s the high volatility that will be most appealing to fans of high-risk slots in Canada. The variance here is set at 10/10 according to Play n Go, and it comes alongside a 20,000x top payout and a 96.2% RTP.

Those numbers make Forge of Gems a true high variance slot with the potential to drive the kind of winning sequences that made popular classics like Bonanza by Big Time Gaming and San Quentin xWays by No Limit City such huge hits.

The setting for Forge of Gems is a fiery furnace in which gemstones of various colours are smelted and bent into shape. Aside from the 5-reel by 3 row grid there is a 5×1 Forge Reel that runs across the top of the main game grid.

Play n Go have clearly borrowed from some of their rivals – namely No Limit City – in creating the feature list for Forge of Gems. It utilises a splitting cells function, found in games like San Quentin xWays, to trigger symbols on the reels to split into two, potentially increasing the win ways from 243 up to 36,288.

In our testing session what we liked most about Forge of Gems was the combination of Cascading Wins and Forge Reel Modifiers that regularly dropped.

In Win Cascades, winning symbols are removed from the reels to be replaced by ones from the Forge Reel. If more wins occur, the process repeats. Whilst this is a regular feature in many Play n Go games, here it is given a twist. The Forge Reel contains special symbols that trigger modifiers like Multipliers, Vertical Wild Reels and Vertical Splitters, where all matching symbols on a reel split into two.

And of course, being a high-risk game, Forge of Gems has a potentially HUGE free spins round up its sleeve as well.

The bonus is triggered by red jewel scatters that give up to 20 free spins if you land five at once. Pla n Go have upped the stakes for the bonus round as multiplier symbols are GUARANTEED to appear on the Forge Reel and if they drop onto the reels then they remain throughout the round, never re-setting.


Play n Go’s Forge of Gems is already available in some real money casinos in Canada as it’s release date was the second week of this month. And by our reckoning it will already be getting a lot of play time. It’s a fiery slot in every respect, from the graphics and theme to the gameplay, features and maths model.

But whilst we believe it will be a hit, it’s worth mentioning too that Forge of Gems will appeal to a particular type of slots player – those that enjoy high risk action and are prepared to sit through a long period of dry spins before a wild ride of intense wins kicks in, triggered by high value multipliers in the free spins round.

So, if you like games like Book of Dead and Reactoonz from the same provider, then we recommend that you give this one a try too.


April is proving to be a big month for slot games in Canada. As well as this gem from Play n Go, we’re also seeing some interesting new games from NetEnt – Funk Master – and Relax Gaming – The Great Pigsby Megapays™. And celebrating the opening of Ontario’s new gaming market, Microgaming have produced a special version of their Mega Moolah Progressive, called Maple Moolah (of course!).
