Set out on a nightmarish adventure and go through hell to strike gold. The game sports crisp graphics and an atmospherically menacing soundtrack, constantly reminding you of the danger lurking in the dark. Four Wild symbols, Multiplier boosters, cascading symbols and two Bonus rounds are some of the surprises in store for you. With a little help from Lady Luck, you could go home with 55,200x your stake.
The royals from 10 to A are low-end symbols, awarding you 1.4x-2.8x the stake. Five different characters are premium symbols, granting you 3.2x-20x for a six-of-a-kind win, Kapitanleutnant being the most generous icon. A Radar represents the Scatter symbol that triggers the Silent Hunter Free Spins (by landing three) and the Wolf Pack Free Spins (for landing four Scatters). Four Wild symbols appear in the game, replacing all other icons, except for Scatters. Red and blue Medals activate xNudge Wild and xWays boosters on the middle reels, with the Charge symbol triggering xBomb Wild Multiplier Booster.
You can place various bets, ranging from $0.2 to $100, and you can set the number of autospins in the game menu. The autoplay feature allows you 10-1000 autospins, and you can adjust other parameters.
You need to land three to six matching icons on neighboring reels from the left to collect a win. There are multiple winning chances, with six-of-a-kind wins paying the best in the base game.
The four middle reels contain boosters triggered by Medals (xWays and xNudge) and Charge symbol (xBomb). If more than a single Multiplier is active, all the generated wins are multiplied together. xWays boosters appear on reels two and five, revealing a random higher symbol, always matching if both are active simultaneously. xNudge Wild boosters appear on reels three and four, filling the reel with four Wild symbols, with each nudge increasing the Win Multiplier by x1. The Charge symbol randomly triggers the xBomb, which explodes and removes all non-winning icons, letting the new ones fall into their place.
During the eight Silent Hunter Free Spins, a Periscope Wild replaces the standard xNudge Wild on reel three. If the first two symbols match, a torpedo launch sequence occurs, increasing the Multiplier by x1. If it hits the boat, the Periscope covers the reel, and if not, it remains a single Wild. For the eight Wolf Pack Free Spins, Torpedo Wilds can hit the four middle reels. Each hit drops an xWays symbol, increasing the Multiplier up to x9. When you fill all the positions, the torpedo launches out of the way, revealing xWays symbols. They are regulars on the reels two and five and Wilds on three and four. Each Scatter landed in both Bonus rounds is worth two extra spins.
