Tempered Steel is a slot developed by Bulletproof Games with an engaging visual design. The game features a 5-reel, 20-payline layout with an RTP of 94% and very high volatility, offering impressive win potential for players of all experience levels.
The RTP of 94% is below the industry average of ~96%. This is common for older slots or those with special features. The lower RTP may be offset by unique mechanics or higher maximum win potential.
Very high volatility delivers the most extreme payout profile — long dry spells punctuated by potentially massive wins. Only recommended for experienced players with substantial bankrolls and high risk tolerance.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Tempered Steel features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
3.0 / 5 — Good
