Das xBoot 2 Zwei is a new video slot from NoLimit City released on 16 December 2025. Players are once again plunged into the icy depths and in control of a German U-boat prowling the ocean depths. A sequel to NoLimit’s popular 2021 release Das xBoot, it extends the studio’s World War II catalogue, alongside Pearl Harbour and D Day.
The core mechanics remain intact, but mechanics that were previously reserved for the bonus rounds now dominate the base game. Periscope Up! and the Torpedo Builder are active throughout the entire game, and during the Free Spins round, they combine to create a destructive finale.
Technical Features
Das xBoot 2 has a distinct reel structure that immediately sets it apart. It plays on six reels arranged in a 2-3-4-4-3-2 row formation, creating 576 ways to win, similar to Megaways slots. Wins are formed by landing at least three matching symbols on adjacent reels from left to right. Bets range from 20p to £100 per spin, so suitable for all types of budgets. The default RTP is 95.94%, a touch below the industry average. Combined with extreme volatility and a max win of 59,999x the bet, Das xBoot 2 Zwei is firmly placed in high-risk territory.
Nolimit City’s original Das xBoot is one of their most successful releases to date. It became an instant hit with players thanks to its unique submarine design, innovative mechanics, and explosive win potential.
Design and Symbols
Das xBoot 2 Zwei is similar to its predecessor, with the action taking place in a cramped submarine steel shell, where every inch of the control room is pressed against the reels. Metal panels flank the grid, pipes snake across the walls, and the gauges overhead flicker as the periscope and targeting controls loom above the action.
Wins are created by landing three to six matching symbols on adjacent reels from the left, and the paytable is split into two groups. The lower-paying symbols are the 10, Jack, Queen, King, and Ace, each etched onto thick steel plates. Six matching symbols award between 0.6x and 0.9x the bet. The higher-paying symbols are crew members: the cook, radio operator, mechanic, navigator, and captain. Landing six matching symbol awards between 1x and 5x the bet.
Special symbols include the familiar xNudge Wilds appearing as red-ribbon war medals, while xWays symbols are the blue-ribbon version of the same design. xBomb symbols are naval mines, and the Bonus symbol is a sonar display, but more on these later in the review.
Das xBoot 2 Zwei Features
The slot has an abundance of features available in the base game and bonus rounds:
xNudge Wilds
The xNudge Wild is a four-stacked symbol and has a very specific place on the reels. During a spin, it only lands on reels 3 and 4. During the Periscope Up! feature, it is restricted to reel 4.
When an xNudge Wild lands, it nudges until it fills the entire reel. Each nudge increases its multiplier by one. When a win involves more than one xNudge Wild, their multipliers are combined before being applied to the payout.
xWays
xWays symbols only land on reels 2 and 5. When it lands, each xWays symbol on the grid reveals two or three instances of a single paying symbol.
xBomb
The xBomb symbol functions as a standard Wild and substitutes regular symbols to help form winning combinations, but it explodes after wins are calculated. All symbols on the grid are removed apart from Wilds and Bonus symbols. A new set of symbols fills the empty spaces, potentially creating new winning combos. Each explosion increases the multiplier by 1.
Periscope Up
The Periscope Up! triggers randomly on any spin, increasing reel 3 to eight positions. If a Periscope Wild lands, a torpedo launch triggers. A direct hit causes the Wild to rise upwards before nudging back down to cover the full reel. The multiplier increases by 1 for each step, but if the shot goes rogue, it acts as a standard regular Wild.
Torpedo Builder
A two-symbol position sits above reels 5 and 6. If a full boat lands in those positions, the Torpedo Builder triggers. You start with 3 respins with only reels 2 to 5 active, supported by a horizontal Torpedo area beneath them. Only xWays and xWays Wilds appear. Each one drops directly into the corresponding position in the Torpedo area and has a value worth +1, +2, or +3.
When the respins conclude, and all four Torpedo positions are filled, the collected symbols transform into xWays symbols and Wilds. They each reveal the respective number of instances accrued during the feature.
If a golden boat appears in a position above the grid, the Golden Torpedo Builder round triggers. Any symbol in the Torpedo area receives values of +8 or +88.
Silent Hunter Spins
Silent Hunter Spins trigger when three Bonus symbols land anywhere on the grid, awarding eight spins. Throughout the free spins, the Periscope Up! remains active. Any multiplier gained through Periscope Up! or xBomb remains active.
Wolf Pack Spins
The Wolf Pack Spins trigger when four Bonus symbols land in the same spin, awarding nine free spins. At the beginning of the round, the Torpedo area beneath the reels is active and filled with all four missile components, each worth 2. These values can be raised further by landing matching symbols on their corresponding reels, following the same logic used in the Torpedo Builder feature.
A launch is initiated when a boat appears in a position above the reels. All symbols in the Torpedo area transform into xWays symbols and Wilds, each revealing their assigned number of instances. All values accumulated in the Torpedo area remain in play for the duration of the feature, and any multipliers from xBomb explosions increase throughout the round.
Atlantic Spins
Landing 5 Scatters on a single spin triggers the Atlantic Spins, awarding ten Spins. The features from previous Free Spin rounds are active, plus the multiplier. Each additional Scatter landing during the feature awards an extra 2 Free Spins.
Nolimit Booster
The Nolimit Booster menu provides several ways to modify the base game:
⭐ 1.5x = Guarantees one Bonus symbol on every spin.
✅ 8x = The Periscope Up!
⚡ 20x = The Torpedo Builder feature.
➡️ 4,500x = The Golden Torpedo Builder feature.
Feature Buy
Those who prefer to jump directly into the features can purchase the bonus rounds.
⭐ 80x = 8 Silent Hunter Spins.
✅ 250x = 9 Wolf Pack Spins.
⚡ 750x = 10 Battle of the Atlantic Spins.
➡️ 290x = Triggers a Lucky Draw, with a 50% chance of triggering Silent Hunter Spins and 25% for each of the remaining bonus modes.
⚠️ Note: Bonus Buy options are not available to UK players.
Verdict
Nolimit City set the bar high with Das xBoot, but the sequel surpasses it. Das xBoot 2 Zwei demonstrates how Nolimit City understands the concept and popularity of the original and has tweaked it enough to gain a whole new audience of dedicated enthusiasts. The expanded feature set gives it a broader rhythm, and the increased max win of 59,999x more than matches the intensity level.
The abundance of features extends beyond the bonus rounds, making it a clear win in our view. It’s a challenging slot, yet its depth and volatility make it appealing to those who prefer slots that push boundaries. The abundance of features is not limited to the bonus rounds, which is a definite advantage. For players who prefer more demanding gameplay, this sequel is a no-brainer!
