Tempered Steel (Yggdrasil Gaming) – Review & Demo Play

Tempered Steel Slot Overview

I step into a blacksmith full of lethal weapons in Tempered Steel from Bulletproof Games. It runs on 5 reels, 3 rows and 20 paylines, with high volatility and an RTP set at 96% in the best model, though lower RTP builds exist. Bets go from 0.20 to 100, the max win reaches 10000x, and about one spin in four lands as the hit frequency is 24.4%. Bonus Frenzy, Lock and Spin, and Forge Your Weapon fire in the base, while free spins are theoretically unlimited.

Tempered Steel Slot Information

I like the dark grid and the kiln glow in Tempered Steel. Chains hang either side, the logo mixes stiff grey steel and melted yellow, and the reel frame is shiny steel. Wins pay left to right across 20 lines, starting from reel one, and you need three to five of a kind. It all runs smoothly on desktop, notepad and mobile. The setup gives a mystical and exciting feeling that suits the blacksmith theme and the hammering pace of the base game.

The lower paying symbols are clubs, spades, hearts and diamonds cast in semi melted steel. Higher paying symbols are a crossbow, two daggers, a hammer, a sword and a two headed axe. The wild symbol is a bald and bearded blacksmith holding a hammer. It substitutes all paying symbols and appears in stacks up to three positions in the main game, and up to five in free spins. The scatter is melted steel pouring on a BONUS sign and it triggers the feature.

Tempered Steel Slot Features

I rate the Wild Symbol in Tempered Steel because stacked wilds make a difference. In the base it can land up to three high, while the free spins raise that stack to three, four or five based on whether I triggered with 3, 4 or 5 scatters. Landing at least three Scatter Symbols is enough to activate the free spins. That mix sets up the climbing stacked wild action that drives the feature and the better starts.

Lock and Spin in Tempered Steel triggers at random in the base game. Reels run an extended spin with stacked wilds of three positions. Any reel covered by a full stack locks while the other reels respin, and the process repeats until no new stack lands. Forge Your Weapon also arrives at random. I pick one of three hidden weapon symbols and a bunch of extra copies of that symbol drop in for the next spin, which can set up tidy line hits.

Bonus Frenzy in Tempered Steel adds extra Bonus Scatter Symbols to the reels on a random base spin, which raises the chance of hitting the feature. In free spins, kilns under each reel can light and release a climbing stacked wild that moves up one position each spin until it leaves the grid. Each reel can award one. When all fires are out the bonus ends, unless a reactivation relights them and expands any 3 or 4 high stacks by one. The Bonus Buy costs 100x.
