Das xBoot 2 (Nolimit City) – Slot Review

Das xBoot 2 by Nolimit City continues the studio’s signature dark, militaristic naval warfare theme, placing players aboard a German U-boat during World War II. The game is heavily inspired by the classic submarine film Das Boot, with a grim, high-tension atmosphere built around stealth, combat, and survival beneath the ocean’s surface.
The visuals are industrial and oppressive, dominated by cold steel, periscopes, torpedoes, binoculars, and uniformed crew members. Alarms, sonar pings, explosions, and mechanical sound effects reinforce the sense of danger, making every spin feel like a tactical manoeuvre rather than casual gameplay. The tone is deliberately serious and intense, reflecting Nolimit City’s preference for raw, uncompromising themes.
Compared to the original Das xBoot, the sequel retains the same core setting and aesthetic but significantly amplifies the scale and chaos. While the first game introduced players to submarine combat with torpedoes, periscopes, and xWays mechanics, Das xBoot 2 expands on this foundation with more complex systems, larger reel structures, escalating multipliers, and layered bonus modes that simulate full-scale naval warfare. The sequel feels more cinematic and relentless, turning isolated encounters into prolonged battles with compounding risk and reward.
Das xBoot 2 features a dynamic reel layout that can expand from 2-3-4-4-3-2 up to 2-4-8-5-4-2, offering 576 paylines. This is a high-volatility slot with an RTP of 95.94% and an exceptionally high maximum win of 59,999x. Bets range from £0.20 to £100.
Das xBoot 2 Symbols & Pay Table

The game includes 14 symbols in total. Five low-paying symbols are represented by the card ranks 10, J, Q, K, and A, while five premium symbols depict character portraits with blue, green, purple, red, and yellow backgrounds. The yellow character is the highest-paying regular symbol, awarding 5x for six of a kind. Additional special symbols include the Wild, xWays, xBomb, and Bonus symbols.
Das xBoot 2 Features & Mechanics

xNudge Wild and xWays
The xNudge Wild is a four-row-high Wild that always nudges into full view when it lands, increasing a Wild multiplier by +1 with each nudge. It can appear only on reels 3 and 4, except during the Periscope Up! feature, where it is limited to reel 4. All Wild multipliers stack and are applied to the final win.
The xWays symbol appears exclusively on reels 2 and 5, revealing a random regular symbol in sizes ranging from two to three positions. If multiple xWays symbols land, they all reveal the same symbol, increasing the number of winning ways.
xBomb Feature
The xBomb Wild substitutes for all symbols except Bonus symbols and detonates to remove all non-winning symbols from the grid, excluding Wilds and Bonuses. After the explosion, symbols collapse and refill the reels, while the xBomb increases the win multiplier by +1. Any xBomb multiplier gained during feature triggers carries over into the major bonus modes.
Torpedo Builder and Golden Torpedo Builder
In the base game and Silent Hunter Spins, landing a full boat in the binocular above reels 5 and 6 triggers the Torpedo Builder. A torpedo tube appears beneath reels 2–5, while reels 1 and 6 close. Players have three spins to collect four torpedo parts. Parts landing on reels 2 and 5 add xWays values, while parts on reels 3 and 4 add xWays Wild values. Once completed, the torpedo launches, splitting symbols into multiple ways or Wilds based on the collected parts.
Landing a golden boat instead triggers the Golden Torpedo Builder, where torpedo parts carry significantly higher values of +8 or +88.

Periscope Up!
During Periscope Up!, reel 3 expands to eight positions and introduces the Periscope Wild. When it connects symbols across reels 1 and 2, a torpedo is fired. A successful hit causes the Periscope Wild to nudge through the reel, adding a multiplier for each nudge. If the target is missed, it acts as a standard Wild. This feature can trigger randomly in the base game and Wolf Pack Spins and remains permanently active in Silent Hunter Spins and Battle of the Atlantic Spins.
Bonus Features
Bonus symbols can land on all reels and trigger three distinct bonus modes. Three Bonuses award 8 Silent Hunter Spins, four trigger 9 Wolf Pack Spins, and five activate 10 Battle of the Atlantic Spins.
Silent Hunter Spins keep Periscope Up! active on every spin. Periscope nudges build a persistent multiplier, while each xBomb adds +1 to the multiplier for the remainder of the feature. Additional Bonus symbols award +2 spins.
Wolf Pack Spins focus on the Torpedo Builder mechanic. The torpedo tube starts pre-loaded with xWays and xWays Wilds, and torpedoes can be launched repeatedly whenever a full boat lands. xBomb multipliers persist throughout the feature, and extra Bonus symbols again award +2 spins.
Battle of the Atlantic Spins combine both Periscope Up! and Torpedo Builder mechanics, creating the most explosive feature set. All multipliers stack additively, xBombs continue to increase the multiplier, and Bonus symbols award extra spins.
Conclusion
Das xBoot 2 is a brutal, uncompromising slot that fully embodies Nolimit City’s extreme design philosophy. The layered mechanics, escalating multipliers, and multiple bonus modes create relentless tension, while the dark naval warfare theme enhances the sense of danger on every spin. Its massive win potential is balanced by punishing volatility and a complex rule set that won’t appeal to casual players. However, for those who enjoy high-risk gameplay and deep, feature-heavy slots, Das xBoot 2 stands as one of Nolimit City’s most ambitious and intense releases.
