Gem Fire Frenzy Details, RTP and Volatility

The Gem Fire Frenzy slot from Hammertime features a grid of five reels and four rows. Released in October 2023, this medium-volatility slot offers a maximum RTP of 96.00%. However, be warned – lower rates of 94.00%, 92.00% and 86.75% also exist.

To spin, you must place a bet between $0.10 and $30, which can produce a maximum potential payout of 7,500x. Three or more identical symbols must land on any of the 1,024 paylines to form a win.

Card icons, plus yellow, blue and purple gems fill the grid during the Gem Fire Frenzy base game, following an $83.50 win.

Theme & Graphics in Gem Fire Frenzy

In the Gem Fire Frenzy slot, Hammertime transports us to a fiery cave that’s filled with glistening red gems. In addition, a purple, gold-rimmed grid hosts gems of different shapes and colors.

Filtering through your speakers as you spin is a slow-paced, medieval-style tune that grows faster and more dramatic during the bonus round. This combines nicely with the game’s playing card icons, which feature a Gothic-style design.

Gem Fire Frenzy Slot Features

The Gem Fire Frenzy slot is simple yet engaging, as you’re about to discover. In this section of our review, we’ll run through the game’s features.

Regular Symbols

Gem Fire Frenzy features 12 regular symbols. The low-paying set are gold-colored, medieval-style playing card icons, ranging from 9 to A. These pay from 0.10x to 2x whenever you land three, four or five on a payline.

Purple, blue, green, yellow, gold and red gems offer bigger rewards, ranging from 3.2x to 6x for five-of-a-kind. However, you only need to match three of each to secure returns of 0.4x, 0.5x or 0.6x.


Look out for the game’s logo, with its fiery purple glow, because this serves as the wild symbol. It can replace all other symbols except the scatter.


This game’s scatter is a silver plate with a hammer imprinted on it. Land five or more on the grid simultaneously to trigger the free spins bonus, which we’ll describe later in our Gem Fire Frenzy review.

Rolling Reels

Gem Fire Frenzy boasts a cascading reels mechanic known as Rolling Reels. This activates after every win, removing winning symbols so that new ones can roll in to replace them. The feature continues until no more new wins are formed.

Synced Reels

This occurs randomly during the base game, and for every play during the free spins round. When active, the feature causes two, three or four reels to synchronize and land matching symbols. 

In addition, if the Rolling Reels feature comes into play on any synchronized reels, these will also produce identical symbols.

Free Spins

Landing between five and ten scatters will trigger ten, 12, 15, 18, 20 or 25 free spins. However, you can choose between two different bonuses: Growing Multiplier Free Spins and Rolling Multiplier Free Spins. 

The former begins with a 1x multiplier that increases up to 50x with each spin. However, in Rolling Multiplier Free Spins, the multiplier starts at 2x and increases by two with each roll, stopping at 20x. This value also resets after every spin. 

Both of the Gem Fire Frenzy slot bonuses retrigger if one or more scatters appears on each reel. This results in three three extra spins.

Buy Free Spins

The easiest way to access the bonus games is through the Buy Free Spins feature. You can purchase 15, 18, 20 or 25 free spins for 80x, 120x, 160x or 250x your bet, respectively.

Five Hammer scatters pop off the grid during Growing Multiplier Free Spins, with a 3x multiplier and seven free spins left.

How to Play Gem Fire Frenzy Online

Many new slots stick to a classic formula, and Gem Fire Frenzy is no different. Start by selecting a bet using the casino chip button, then spin with the red “Play” icon.

As highlighted earlier in this Gem Fire Frenzy review, landing three or more identical symbols on a payline results in a win. Further, matching symbol combinations are only valid if they land on adjacent reels.

Gem Fire Frenzy Review – Our Final Verdict

With its Gem Fire Frenzy slot, Hammertime Games has reinforced the idea that casino games can be simple but entertaining. They’re certainly not reinventing the wheel here, yet this is a reasonably enjoyable game to play. 

A 7,500x maximum win isn’t the biggest, but it still offers solid appeal. While the optimal RTP of 96.00% is neither amazing nor terrible. Free spins with multipliers, cascading symbols and synced reels are anything but new inventions. And gem-themed games are a dime a dozen. Everything so far is decidedly ordinary, including the medium level of volatility.

We did, however, enjoy the choice of free spins bonus. They’re not wildly different, but the ability to pick your preference is one of the game’s nicer touches. 

Overall, this is a fairly middle-of-the-road slot that’ll most likely appeal to casual gamers and newcomers. Especially given the game’s low betting limits.
