Forge of Gems

Forge of Gems by Play’n GO doesn’t just dust off the familiar gem slot theme—it takes players deep into a red-hot underground forge, where stones are transformed into sparkling jewels amid sparks and roaring flames. The moment the reels load, you’re greeted by a rich steampunk-inspired design, all iron frames and glowing embers, with jewels that shine all the brighter against the moody, industrial background. There’s a certain restrained confidence in the sound design, too: just the clink of stones and rumble of furnaces, letting the spins and shatters stand out without an intrusive soundtrack. Under all this style lurks serious substance—a high volatility slot, clocking in at 96.20% RTP, that can yield big wins for those with the patience and nerve to keep forging ahead.

Symbols and Payouts

If you’re checking the paytable, the first thing you’ll notice is how Forge of Gems layers its symbols. The basics—10 to Ace card symbols—cover the low-paying end, blending in well enough with the metallic backdrop without distracting from the real action. Things get interesting with the mid-tier and high-paying symbols: colored gems that catch the light beautifully. Blue, green, yellow, red, and purple stones can drop in, with the blue gem leading the pack and offering the best payout among them. Land five of these blue beauties, and you'll earn 1.5x your stake, which seems modest but can quickly ramp up thanks to the slot’s cascading mechanic and bonus features.

The real star, though, is the wild diamond. Landing five diamonds can award you 4.5x your bet, but wilds do far more than just pay—they substitute for all regular symbols, dramatically boosting your chances for full-screen wins, especially in combination with splitting and expanding symbol mechanics. The red jewel scatter has its own role, unlocking the slot’s biggest bonus moments. Every piece of the symbol set fits the theme—no distracting characters here—making the experience feel cohesive but maybe a bit impersonal for those who crave narrative or mascot-driven slots.

Bonuses and Free Spins

Forge of Gems stacks up the features in a way that might seem overwhelming at first, but once you’re spinning it’s easy to get hooked on the interplay between the main grid and the unique Forge Reel. Here’s how it works: every spin is powered by a 5x3 grid, with an extra Forge Reel perched on top. When a win triggers a cascade, symbols drop away and new ones fall down. The top Forge Reel introduces special symbols into the cascade, each with its own function. Multipliers can stack with every cascade, adding extra excitement to longer win chains. Vertical and horizontal wilds can convert entire reels or rows into wilds, and splitters (both vertical and horizontal) duplicate symbols on their lines, dramatically boosting the potential number of ways to win—up to a staggering 36,288 on a single spin.

When you manage to land three or more red jewel scatter symbols, that’s when the real fireworks start. You trigger the Gem Box feature, which can award either instant cash or a set of free spins—and the more scatters you land, the bigger the rewards. For example, three scatters grant you either an instant 20x your bet or 8 to 10 free spins; bumping up to four or five scatters increases both the payout and the number of possible free spins (up to 20). During the free spins round, the bonus reel never goes blank—every cascade drops a special symbol, usually a multiplier, and most importantly, the win multiplier doesn’t reset between spins. This makes the bonus round where high-volatility dreams can turn into reality, as multipliers can keep climbing. However, you can’t retrigger extra free spins within the bonus—so it’s all about making each one count.

There’s no progressive jackpot in Forge of Gems, but with potential wins of up to 20,000x your stake, there’s plenty of high-end upside for those chasing big hits.

Getting Started

The Forge of Gems slot interface sticks with the familiar Play’n GO setup, so you’ll feel at home if you’ve played their other releases. Bet settings are always right under the reels; just slide the arrows to pick your stake anywhere between €0.10 and €100 per spin. The green spin button sits front and center—it’s as simple as clicking it to get going. For longer sessions or if you just want to watch the features unfold, use the autoplay to set up a queue of spins. There’s also a turbo option if you want to cut straight to the outcomes with less waiting between spins.

Unlike classic slots with defined paylines, Forge of Gems uses a ways-to-win system; starting at 243 ways, it expands with splitters to a wild 36,288 ways in peak moments. Want to check payouts or see what each symbol or Forge Reel feature does? Tap the ‘i’ button to browse the paytable—it’s all laid out clearly. There’s no gamble feature here, and paylines aren’t adjustable—the focus is on stacked features and big, cascading moments.

If you’re curious but not quite ready to play with real money, the Forge of Gems demo is a perfect way to see the mechanics in action. It looks and feels identical to the main game, so you’ll get the full experience risk-free before you jump in.

Is Forge of Gems Worth Playing?

Forge of Gems stands apart from many gem-themed slots thanks to its mechanical depth and darkly industrial visual style. The variable ways to win, cascading system, and the innovative Forge Reel steer this game firmly toward those who like intricate features and a bit of unpredictability. Every spin can quickly escalate, especially in the bonus, and the lack of a progressive jackpot is offset by the 20,000x max win potential.

This slot is a natural fit for players who enjoy high-volatility action—the ones who appreciate patience and a well-timed bonus hit. Fans of simpler or traditional slots might find the feature set a bit much, especially if they prefer more straightforward paylines or a less mechanical atmosphere. The design can feel a touch cold at times, with no characters to warm things up, but the satisfying animations and slick interface make up for it.

Overall, Forge of Gems is a must-try for those craving depth and excitement in a slot, especially if you like the high-risk, high-reward play style. The Forge of Gems free play option is great for testing the waters. With a solid RTP, transformative features, and cascading fun, it deserves a spin from anyone looking for a new gem in their rotation—just make sure you bring a bankroll and a bit of nerve.
