Sound Of Steel Hold And Win by 1spin4win is a slot with a steel-themed battle setting, centred on the conflict between Masahide and Koniro near Mount Fuji. The game uses nine letter-scrolls on the reels, while the Wild symbol substitutes for all symbols except Coins, helping to build standard wins across the 27-payline layout.
The main feature is the Hold and Win round, which starts when three or more Coins land. In this mode, Coins lock in place and respins continue until no new Coin appears. Players can choose an ally before the duel begins, and the Buy Bonus option is available for immediate entry into the bonus feature. Special Coins include a Mini Jackpot Coin linked to a x100 Minipot prize.
Collecting all nine Coins in the Hold and Win round awards the x1,000 Megapot. The slot is listed with high volatility and an RTP of 97.1%, with bets from 0.01 to 50. The demo version is available to play for free, which lets users practice before playing for real money.
