Das xBoot 2 Online Slot Review

4.5 /5

Jumping into a real session with Das xBoot 2 (or Zwei) instantly brings that signature Nolimit City pressure. Every spin feels tense, like you’re navigating a submarine in hostile waters, especially when xNudge Wilds start shifting into place and pushing multipliers upward. The way the reels expand, tighten, and tease bigger ways-to-win keeps each round unpredictable, while torpedo-style features and sudden symbol upgrades create those “hold your breath” moments that only this studio can deliver. When everything aligns, the hits feel explosive and deeply satisfying.

The free spins ramp things up even further, embracing the game’s extreme volatility. Wins may come in waves, but the build-up, the suspense, and the sudden bursts of underwater chaos make the gameplay unforgettable—perfect for players who love playing high-intensity games at top online slot casinos. Keep reading my full review to discover how the features, mechanics, and long-session swings truly play out in Das xBoot 2.

Graphics, Sounds and Animations

4.5 /5

The online slot throws you straight into a tense, deep-sea war zone with gritty visuals and a cold, industrial submarine environment. The metallic interiors, radar screens, oxygen gauges, and torpedo tubes are rendered with impressive detail, giving the slot a dark, cinematic feel. Symbols like crew members, sonar charts, and submarine equipment fit perfectly into the theme, while the animations — especially xNudge Wild movements and sudden screen distortions — add intensity without overwhelming the gameplay. Every action feels deliberate and helps build that constant sense of pressure.

The sound design completes the immersion. A low, rumbling atmospheric track plays underneath echoing sonar pings, warning beeps, and mechanical submarine noises. Bonus triggers and high-impact hits burst with dramatic audio cues, making big moments feel explosive and memorable. The combination of gritty visuals, sharp animations, and atmospheric soundscapes makes Das xBoot 2 feel like a fully immersive underwater mission every time you spin.

RTP, Payout and Volatility

4.5 /5

Das xBoot 2 runs with an RTP that varies between 95.94% and 96.07%, depending on which features are active, with high volatility. My personal session reflected that perfectly. I played 6 spins at €10 each and 2 spins at €5 each, making a total stake of €70, and my final winnings amounted to just €11. This kind of return is very common in a high-volatility Nolimit City slot — the game can feel dry for long stretches until the features, multipliers, and wild nudges all line up at once.

Even though the payout wasn’t in my favor this time, every spin carried that trademark submarine tension. xNudge Wilds, expanding ways, and torpedo-style features constantly teased big outcomes, keeping the excitement alive despite the losses.

Das xBoot 2 is clearly built for players who enjoy high-risk gameplay, deep volatility swings, and the thrill of chasing that massive 59,999× max win — not for casual players, but perfect for adrenaline-seekers who love to experience explosive moments while playing slots at the latest online casinos.

Features

4.5 /5

When I played the game at SiGMA Play, I saw that it centres on a complex mix of xNudge Wilds, xWays, xBomb multipliers, and several escalating free spin modes that build tension with every spin. The game layers Torpedo Builder, Periscope Up!, and three distinct free spin rounds, all of which can carry multipliers forward for explosive, high-volatility payouts. Extra paid spins after bonuses further extend hot streaks, appealing strongly to aggressive bonus hunters.

xNudge Wild

The xNudge Wild is a 4-high wild that always nudges to become fully visible, increasing its win multiplier by 1 with every step. It can land on reels 3 and 4 in most modes (reel 4 only during Periscope Up!), and all wild multipliers stack before the final win is calculated.

xWays

xWays symbols land on reels 2 and 5, revealing 2–3 matching regular symbols and boosting the number of ways to win. When more than one xWays symbol appears, they all reveal the same symbol type, making it easier to connect across the grid for larger hits.

xBomb

xBomb symbols substitute for all regular symbols except scatters and other wilds, then explode to remove non-winning symbol types and refill the grid. Each explosion increases the global win multiplier by 1, and any multiplier active when features trigger is carried into Torpedo Builder and all free spin modes for sustained pressure.

Periscope Up!

Reel 3 can extend up to 8 positions, allowing a special Periscope Wild to land and trigger a torpedo sequence. If the torpedo hits its target, the Periscope Wild expands to the top and nudges down, adding a multiplier for every step, while in Silent Hunter Spins and Battle of the Atlantic Spins this feature remains constantly active.

Torpedo Builder

Landing a full 2-symbol-wide boat in the Ocular above reels 5–6 activates Torpedo Builder in the base game and Silent Hunter Spins. A Torpedo Tube appears under reels 2–5, where Torpedo parts drop xWays and xWays Wild values that are collected, then revealed as split symbols and split wilds once the torpedo finally launches.

Golden Torpedo Builder

In the base game and Silent Hunter Spins, landing a golden boat in the Ocular triggers the Golden Torpedo Builder. Here, collected Torpedo parts only carry premium +8 or +88 values, creating a much more potent torpedo launch when all sections are complete.

Silent Hunter Spins

Landing 3 scatters awards 8 Silent Hunter Spins, where Periscope Up! is always active for the entire round. A persistent multiplier begins at 1x after the first Periscope Wild nudge, then increases with each further nudge and any xBomb hits, while extra scatters add +2 spins to keep the round alive.

Wolf Pack Spins

Hitting 4 scatters in the base game triggers 9 Wolf Pack Spins, introducing a Torpedo Tube under reels 2–5 where Torpedo parts fall. The tube starts preloaded with xWays and xWays Wilds of size 2, with each Torpedo part boosting these values before the torpedo launches to unleash upgraded splits and wilds on the reels.

Battle of the Atlantic Spins

Landing 5 scatters unlocks 10 Battle of the Atlantic Spins, where both Periscope Up! and Torpedo Builder are active simultaneously. Every xBomb hit increases a persistent multiplier for the rest of the feature, extra scatters grant +2 spins, and fully built torpedoes can repeatedly relaunch for chained wins.

Extra Spin

After any free spins bonus finishes, players may be offered the chance to buy one extra spin, depending on the total win and current feature state. Existing multipliers and Torpedo Tube progress are preserved, and the extra spin is only offered if its cost is less than or equal to the amount already won, making it a calculated, value-based gamble.
