How to Play

Here is a step-by-step instruction to start playing the Tempered Steel online slot:

  1. Find the game in the catalog of an online casino
  2. Start the slot and wait until the end of content loading
  3. Click to continue on the main board
  4. Select a stake in the special section of the control panel. The min bet is €0.2, while the max bet is €100
  5. Start playing. You spin the slot manually or with an auto-play

Tempered Steel has a classic 5x3 grid with 20 fixed playlines. The winning line pattern is traditional, as you need to land a similar symbol on 3 consecutive cells starting from the leftmost side to get a win.

The game offers 3 random features in the main game and a separate FS round. You can also buy free spins at a fixed price of 100x.

RTP and Volatility

The slot’s RTP is 96%, while its volatility is high.

The high volatility of Tempered Steel is the result of 3 random features and high-paid symbols. The difference between winnings of two consecutive spins can be huge. Despite the high variance, durable empty streaks don’t happen that often. The hitting rate of the slot is 1:4.

The level of payback is about the industry’s average. But don’t ignore the fact that RTP covers over potential wins from random features and free spins. So, it’s better to play the slot for longer sessions.



Tempered Steel

Tempered Steel brings back to the times of brutal muscular blacksmiths somewhere in the Middle Age. Those guys were spending hours in inhuman conditions producing all kinds of weapons for future wars. And you can see those weapons like swords, knives, and axes.

The atmosphere around the slot is very brutal due to the tense soundtrack and the background of a flaming factory. The game is total masculinity!

A total of 11 symbols are present in the game. The package is usual with regular elements, wild and scatter. There is also a classic group of card-suit symbols but stylized ones. The high-paying symbols are: mechanism, knifes, hammer, sword, and axe.

The wild symbol substitutes regular elements on winning lines and has the highest odds. Three scatter symbols trigger free spins.

Bonus Rounds & Free Spins


In Tempered Steel, you can trigger free spins with at least 3 landed scatter symbols or get a random main game feature. Let’s learn every special mode of the slot.

Random features

During the base game, you can get the following random features:

  • Bonus Frenzy. At least one bonus symbol will appear, increasing your chances of triggering the FS round.
  • Lock and Spin. At least one locked stack of wilds will appear. It can be a full reel or the reel with 1 or 2 wilds. The round continues as long as you get an additional locked reel (or reels) or until all 5 reels are locked with wilds.
  • Forge your weapon. The game will offer you to smash one of 3 rocks. Click 3 times on the rock to reveal the stack of high-paid symbol. Right after, one or a few stacks of reels of the revealed high-paid element will appear on the reels.

Free spins

Getting at least 3 bonus symbols in view triggers free spins with moving wild reels. The conditions of the FS round depend on the number of landed bonus symbols:

  • 3 – the height of the wild stack will be 3 symbols;
  • 4 – the height of the wild stack will be 4 symbols;
  • 5 – the height of the wild stack will be 5 symbols.

You can see 5 forges below each reel at the start of free games. A wild stack appears on the corresponding reel when the forge is lit. For starters, you’ll see the only wild symbol in a view. But with each spin, the wild stack will be moving upwards by one row until it disappears. So, if you got a stack of 3 wilds height, it will be in a full view on the 3rd spin after activating the forge.

The activation of forges is totally random. All of them can be active simultaneously, or you can wait for 10 spins between activations. The best part is that free spins continue until the disappearance of all stacks from the playing field.

Another good news is that free spins can be randomly re-triggered right after the disappearance of the last tack. What’s even better is that the height of stacks will be increased by 1. The only exception is when the FS round was previously triggered by 5 scatter symbols. In that case, the stack height remains at 5 symbols.

A slot with classic free spins round and additional perks. The free spins are really generous and trigger often. As for other features, I hadn't had such an amazing experience. One works as a double chance for triggering free spins round, other two usually bring not very high payouts. I mean my hit in forge your weapon round was 15x while in free spin I had 130x. My opinion is positive, I think this one worths a try especially if you like classic 5x3 games
