Full Rules & Information About the Dark Forge Online Slot

Dark Forge has a 4-5-5-5-4 grid with 2,000 paylines and an RTP of 96.02%. Paylines pay left to right, and wilds substitute for all symbols except for scatters.

Unlike most games at the top online slot casinos, Dark Forge features an Avalanche mechanic. When you make a match, winning symbols drop, and new ones fall down to replace them. The multiplier meter resets at the beginning of a new game round.

Two special A-shaped symbols can also appear on the middle three reels. The Lightning symbol removes upcoming multiplier steps from the Multiplier Meter, creating a shortcut to higher values. The Gold symbol, when part of a win, converts into a wild.

Stakes vary from £0.20 to £5, and the Xtra-Bet option increases your stake by 50% to make free spins 2.6x more likely to trigger. Burst Mode is also available if you prefer a faster pace.

Dark Forge Symbols & Payouts

Dark Forge’s paytable features 12 symbols. There are four royal card ranks (J, Q, K, A) as lower-paying symbols, and the high-paying hammer, mace, axe, sword, and demon. Scatter (silver skull), Super Scatter (golden skull), and a wild (W letter) are also available.

Landing five of a kind pays 0.25x for royals and between 0.4x and 2x for premium symbols. Wilds substitute for all except scatters, while the special A-shaped Lightning and Gold symbols can appear on the middle three reels.

Super Scatter symbols trigger the Super Scatter Free Spins.

• All symbols: 12
• Highest-Paying Symbol: Demon
• Wilds: Yes
• Paylines Pay: Left to Right
• Maximum Win: 20,000x

Dark Forge Bonuses & Features

Match 3, 4, or 5 scatter symbols to activate the free spins bonus. If a Super Scatter appears, you’ll unlock Super Free Spins. During this round, all symbols on the middle reel appear as Lightning or Gold, which increases your winning potential.

You can get up to 12 free spins by landing 5 scatters.

On top of that, you can use Xtra-Bet to increase your chances of triggering free spins. You can also click the Fast Track button to buy them directly.

Dark, Loud, and Seriously Metal

Dark Forge targets a specific audience – heavy metal and dark fantasy fans. But if you’re neither, don’t skip it – I’m sure the 20,000x potential payout appeals to everyone. I loved the avalanche mechanics, which make the base game entertaining.
