Das xBoot Slot Game Review

The original German film 'Das Boot' from 1981 has inspired numerous memorable movies. NoLimit City has successfully captured the intense underwater atmosphere of this classic in their slot game, Das xBoot. The distinctive "ping" sound when a Sonar Display scatter symbol appears can evoke claustrophobic feelings, reminiscent of films like 'The Hunt for Red October' and 'Crimson Tide'. This submarine is 'rigged for red', featuring a comprehensive and complex array of features. You will join the German crew on a typical World War 2 submarine, where you can 'run silent and deep' for a period, before sudden feature triggers lead to substantial payouts. The Silent Hunter bonus round allows you to sink battleships with torpedoes, and the top-tier Wolf Pack feature centres on completing xWays loaded torpedoes.

This is another highly impressive offering from a developer that, for now, surpasses all others. The game immerses you in the role of the submarine crew, with the five premium symbols representing different members: the chef, radio operator, engineer, periscope operator, and the Kapitanleutnant. The Kapitanleutnant is the highest-paying symbol, offering 20 times your stake for a win of six symbols. Other premium symbols provide payouts ranging from 3.2 to 10 times your stake for the same combination. The xNudge Wild symbol is stacked four rows high and always nudges into place fully when it lands. Each nudge increases the wild multiplier by +1. This symbol appears exclusively on reels 3 and 4 in the base game. If multiple multiplier wilds are part of a win, their multipliers are combined before being applied. You will encounter xWays symbols on reels 2 to 5, which reveal two to three instances of a randomly chosen regular pay symbol. All xWays symbols that land on the same spin will reveal the identical random symbol, thereby increasing the number of available win ways, which can be tracked on the meter above the grid.

When an xBomb Wild symbol lands, the global win multiplier increases by +1. The xBomb symbol then explodes, removing all non-winning pay symbols. The xBomb itself transforms into a regular wild symbol and drops to the lowest possible position, along with other symbols that were not removed. A new set of symbols will then fall from above to fill the gaps. The win multiplier is carried over if you trigger a bonus round.

Das xBoot Slot Free Spins

You can land the Sonar Display scatter symbol on reels 2 to 5 only. Landing three of these symbols triggers the Silent Hunter Bonus Round, which awards eight free spins. During this round, reel 3 expands into a periscope reel that is eight rows high. If you land matching symbols on reels 1 and 2, combined with a Periscope Wild on reel 3, you activate the Torpedo Launch feature. You will observe enemy ships through the periscope, and a torpedo is launched towards one of them. If you successfully sink the target, the Periscope Wild expands to cover reel 3 entirely. The global win multiplier increases by +1 for each torpedo attack triggered, and the periscope wild multiplier increases by +1 per nudge before the full reel is covered. If you miss the target, the wild remains at its 1x1 size. You receive +2 extra spins for each scatter symbol you land.

The top-tier Wolf Pack Bonus Round is triggered by landing four Sonar Display scatters. Below reels 2 to 5, a torpedo tube will appear. Landing torpedo wilds on reels 2-5 causes a metallic xWays symbol to drop down, assisting in completing the torpedo. Each starts with a value of x2, which increases by +1 for each new torpedo wild drop-down, up to a maximum of x9. Completing a torpedo by filling all four positions triggers a torpedo launch, revealing the accumulated xWays symbols. The positions on reels 2 and 5 will transform into the number of xWays Symbols you have collected, while positions 3 and 4 will transform into the applicable number of xWays Wilds. Each torpedo launch increases the win multiplier by +1, and scatter symbols grant +2 extra spins whenever they land.

The Bonus Buy feature is available, though not in all jurisdictions. For eligible players, the Silent Hunter Free Spins can be purchased for 75 times your stake, and the Wolf Pack feature costs 350 times your stake. In these instances, the RTP increases to 96.57% and 96.58%, respectively.

The 200 Spins Das xBoot Experience

You will experience a brief introduction to the base game before the Silent Hunter Bonus Round is triggered. During this feature, at least one ship is sunk, followed immediately by the triggering of the Wolf Pack Free Spins. You can view the gameplay by playing the provided video.

Review Summary

Capturing the claustrophobic atmosphere of a World War 2 submarine so effectively in a video slot is a remarkable achievement. The underwater sound effects and the ominous soundtrack blend seamlessly, immediately drawing you into the action. The game also offers a glimpse inside the 'rigged for red' periscope deck when the xBomb symbol removes symbols. Every element has been masterfully crafted to enhance the theme, from the expanded periscope reel in the Silent Hunter round to the torpedo launch feature in the Wolf Pack feature. The retro comic book visuals are perfectly suited to this game, making other developers' current offerings seem rudimentary in comparison to the intricate and impactful creations NoLimit City consistently produces.

• xWays symbols on reels 2-5
• xBomb Wild increases win multiplier
