Tempered Steel

Tempered Steel, developed by Yggdrasil, is a video slot that immerses players in the atmosphere of a blacksmith's forge, featuring a 5×3 reel setup with 20 paylines. The game's aesthetic is dominated by dark, fiery visuals, highlighting metallic symbols and weapons crafted in flames, including hammers, swords, axes, and daggers. The blacksmith himself serves as the Wild symbol, which can replace all paying symbols except for the scatter symbol, referred to as "Bonus."

In the base game, players may trigger three bonus features at random: Lock and Spin, Bonus Frenzy, and Forge Your Weapon. During the Lock and Spin feature, if a stack of wilds lands, the reel with the wilds locks in place while the other reels respin; locking multiple reels grants additional respins until more wild stacks appear or all reels are locked. Bonus Frenzy adds extra scatter symbols to the reels, increasing the likelihood of entering the free spins round. The Forge Your Weapon feature allows players to break three rocks, revealing a weapon that can then stack on one or more reels.

Tempered Steel distinguishes itself with its "unlimited" free spins feature: when players collect at least three scatter symbols, the free spins round activates with forges beneath each reel. Each spin can trigger one or more forges that create a wild stack on the corresponding reel. The wild stack ascends one position with each spin until it exits the screen, extinguishing the forge; the game ends when all forges are off, but they can randomly reactivate, potentially enlarging the wild stacks if they haven't reached their maximum size.

When permitted by regulations, a Buy Bonus option is available, allowing players to instantly access the free spins round for a cost of 100 times their bet, ensuring at least three scatter symbols. This high volatility game emphasizes symbol combinations, stacked wilds, and the excitement of bonus reels, delivering a thrilling gaming experience.
