Das xBoot 2wei

Das xBoot 2wei Review

Developer Nolimit City has already dipped into the war-themed slot niche several times, with WW2 being a recurring point of reference – and they clearly have no intention of leaving it behind. One of those earlier attempts was Das xBoot, released in 2021, a tense and uncompromising slot that placed players aboard a German submarine on a hostile deep-sea mission.

Four years later, Das xBoot 2wei (or Zwei – meaning ‘two’ in German) revisits that same setting. We’re once again locked inside a U-boat, tasked with hunting down Allied ships and turning the tide of war in the Axis’s favour. In this review, we are going to see how Das xBoot 2wei builds on its predecessor, where it stays familiar, and where it pushes the formula further. Time to submerge.

Dive, dive, dive! The crew has been submerged for over 4 years. Clearing sea mines, dodging enemy patrols and picking off destroyers is all in a day's work for the sub crew. The submarine has gotten a few upgrades since its last deployment. It’s become stealthier and deadlier than ever before.

The mission never changes... hunt prey and don’t get spotted!

The Das xBoot 2 slot machine runs on a 2-3-4-4-3-2 reel layout, delivering 576 default win ways before any modifiers come into play. Sitting above reel three is a Periscope that can significantly extend that column during play, and above reels five and six, an Ocular tracks passing enemy ships, with clear sightings acting as the trigger point for one of the game’s main features.

Das xBoot 2wei Slot – Base Game

Wins are formed by landing at least three identical symbols on adjacent reels, starting from the leftmost. The paytable features ten regular symbols, split evenly between low and high. The lower section consists of themed card ranks, which pay between 0.6x and 0.9x the stake for 6-of-a-kind. The premium lot is represented by five members of the crew, including the cook, the radioman, the mechanic, the lookout, and the captain himself, awarding from 1x to 5x the stake for combinations of six.

Bet sizes range from €0.20 up to €100 per spin, which is a standard NLC range that should suit both casual players and high rollers. From a numbers standpoint, the Das xBoot 2wei online slot sits firmly at the harsher end of Nolimit City’s portfolio. The game is shipped with three RTP configurations – 95.94%, 94.02%, and 92.03%. Volatility is labeled as ‘extreme’, rated at the maximum 10 out of 10.

The overall hit rate is 21.75%, meaning wins should occur roughly in 1 out of 5 spins, while the free spins feature tends to pop up once every 273 spins on average. Compared to the original game, Das xBoot 2wei offers a slightly higher top-end potential, now capped at 59,999x the stake, and the odds of hitting that mouthwatering figure are more than twice as high. With the top RTP setting, that outcome is mathematically expected roughly once every 25.3 million spins.

Bonuses And Special Features

Just like the original, Das xBoot Zwei is packed to the brim with features and modifiers that never let you have a dull moment during sessions. Some mechanics return in familiar form, others are tweaked to one extent or another, and a few new additions make an appearance as well. Below, we’ll break down every feature in the game one by one and explain what each one does in practice.

Periscope Up!

Das xBoot 2wei Slot – Periscope Up!

Occasionally, reel 3 can grow to 8 positions high, and a Periscope Wild symbol may land on it. Whenever it does, a torpedo launch sequence is initiated – a target will appear in the periscope and a missile will be fired. If it hits, that Periscope Wild will grow all the way to the top and then nudge down to fill the 3rd reel entirely. Meanwhile, each nudge increases the Multiplier by +1x.

In the base game and Wolf Pack Spins, this feature is entirely random. During the two other bonus modes, namely Silent Hunter Spins and Battle of the Atlantic Spins, Periscope Up! is active on each spin. Finally, Periscope Wild won’t nudge over the symbols revealed from the Torpedo launch.

xSymbols

In true Nolimit fashion, the Das xBoot 2wei slot comes loaded with a bunch of trademarked mechanics, each represented by a special symbol. These are the following:

• xNudge – a 4-position high Wild symbol that always nudges until it’s fully visible. For each nudge, this symbol’s multiplier grows by +1x. Available on reels 3 and 4, or reel 4 only during the Periscope Up! feature.
• xWays – sort of a mystery symbol that reveals a randomly selected regular symbol. If more than one appears, all instances in view always reveal the same symbol. They come in sizes of either 2 or 3 symbols and are available on reels 2 and 5 only.
• xBomb – acts as a Wild symbol and explodes whenever it drops on the reels, removing all other symbols except winning, Bonus, and other Wilds. After the explosion, the total multiplier grows by +1x, the remaining symbols fall down, and then a cascade proceeds, with new symbols filling the empty spaces. If an xBomb coincides with a feature trigger, it will be carried over to the respins or the free games.

Torpedo Builder

Das xBoot 2wei Slot – Torpedo Builder

During the base game or the Silent Hunter Spins bonus, landing a full boat in the Ocular above reels 5 and 6 launches the Torpedo Builder mini-game. Once activated, you get 3 respins to accumulate enhancements for the torpedo, which appears under the four middle reels.

A special grid is used during respins, where only torpedo parts can appear. Reels 2 and 5 can drop only +1, +2, or +3 xWays symbols, while reels 3 and 4 can bring in +1, +2, or +3 xWays Wild symbols. If you manage to collect at least one part on each reel and complete the torpedo, it launches, and all gathered xWays and xWays Wilds unleash. On reels 2 and 5, they are transformed into a random regular symbol and split in the number of ways that were collected. On reels 3 and 4, they convert into Wilds, which also split into an amount equal to the number of collected parts.

Should you have sight of a golden boat in the Ocular, then a Golden Torpedo Builder will be launched instead. In this mode, all torpedo parts come in values of either +8 or +88.

Das xBoot 2wei Free Spins

Here, players will benefit from 3 different types of free spins. They all trigger by landing Bonus, a.k.a. Scatter symbols, on the reels during the base game – the more you manage to catch, the more powerful the bonus round.

• 3 Bonus symbols – activate 8 Silent Hunter Spins.
• 4 Bonus symbols – activate 9 Wolf Pack Spins.
• 5 Bonus symbols – activate 10 Battle of the Atlantic Spins.

Silent Hunter Spins

In this mode, the Periscope Up! feature is persistent, so free spins are played with the expanded 3rd reel. More than that, Periscope Wild nudges award a sticky multiplier that does not reset between spins.

Each time an xBomb lands, it increases the total multiplier by +1x for the remainder of the feature. Every Bonus symbol that appears during free games awards +2 extra spins.

Wolf Pack Spins

During this type of Das xBoot Zwei free spins, a Torpedo Tube appears under the four middle reels, and torpedo parts become available on those reels. This tube is preloaded with xWays and xWays Wild of size 2 at the beginning, and they can be improved as you collect additional parts, just like in the Torpedo Builder feature. When collected, torpedo parts leave a single Wild symbol in their place.

Any time a full boat lands in the Ocular, the torpedo is launched in its current state. Don’t worry, it’ll return back in place in the next spin so you can enhance it further. Similar to Silent Hunter Spins, each xBomb adds up to a total multiplier, and each Bonus symbol awards +2 additional free spins.

Battle of the Atlantic Spins

This one combines the perks of Silent Hunter and Wolf Pack modes. That means that both Periscope Up! and Torpedo Builder features are always active during the round. Again, each xBomb increments the total multiplier value by +1x, and Bonus symbols grant +2 extra spins.

Das xBoot 2wei Slot – Free Spins

Extra Spin

When you run out of free spins, you have the opportunity to purchase one extra spin for an offered price, which will be determined on the current state of the bonus, such as accumulated multipliers or the Torbedo Tube progress. Extra Spin is only offered when that price is less or equal to the total win of that round.

Nolimit Booster/Bonus

For those not willing to wait around for the features to trigger naturally, Das xBoot 2wei bonus buy/bonus bet menu can come in handy, allowing players to activate any of the above-mentioned features immediately for a certain cost.

• Bonus Booster – for a 1.5x increased bet, a Bonus symbol is guaranteed on each spin.
• Periscope Booster – for 8x the bet per spin, the Periscope Up! feature is guaranteed.
• Torpedo Booster – for 20x the bet, a full boat is guaranteed to land in the Ocular.
• Golden Torpedo Booster – for 4,500x the bet, a full golden boat is guaranteed in the Ocular.
• Silent Hunter Spins – 80x the bet triggers the bonus round.
• Wolf Pack Spins – 250x the bet triggers the bonus round.
• Battle of the Atlantic Spins – 750x the bet triggers the bonus round.
• Lucky Draw – 290x the bet awards a 50% chance to activate Silent Hunter Spins and 25% chance for Wolf Pack Spins and Battle of the Atlantic Spins each.

Theme & Graphics

Das xBoot 2wei sticks to Nolimit City’s gritty, comic-book art direction and uses it to sell the WW2 submarine setting from the first second. The reels sit inside the boat’s hull, wrapped in metal plating, gauges, and exposed machinery, while the periscope and the Ocular at the top keep the ‘hunt’ idea present even during standard spins. Backgrounds shift between cold underwater blues and alarm-red battle states, and the UI elements – multipliers, ways counters, and ship sightings – are built into the scene rather than feeling like overlays. Add in the stressed-out crew portraits and the worn, industrial card ranks, and the whole presentation keeps the tone heavy and claustrophobic, exactly as the theme demands.

Pros And Cons Of Das xBoot 2wei Slot

Final Thoughts

After reviewing Das xBoot 2, I can say it delivers exactly what I wanted from a sequel. It keeps the core identity of the 2021 original intact – the gritty setting, the constant sense of pressure, the way features can flip a dead spin into something chaotic – but it doesn’t feel like a simple rerun. The upgraded feature set gives the game more routes to escalate once everything starts connecting.

What we get in practice is the good ol’ Das xBoot, just meaner and bigger. The volatility is unapologetic, the feature triggers aren’t handed out, and the ceiling is there for players who can stomach long stretches of nothing before the reels finally cooperate. When it does turn, though, the sequel has that familiar Nolimit City habit of stacking mechanics on top of mechanics until the screen barely looks like the base game anymore.

Overall, I’d call Das xBoot 2wei a strong follow-up that respects what made the first game memorable while adding just enough new tools to justify the ‘2wei’ in the title. If you enjoyed the original’s structure, this one feels like the same mission with a larger payload – definitely worth your attention.
