Das xBoot 2wei! online slot game
Das xBoot 2wei! marks Nolimit City’s long-awaited return to the depths of World War II submarine warfare. Four years after the original, this sequel resurfaces with a darker tone, refined visuals, and even more tension-packed gameplay. The action unfolds inside a worn, claustrophobic U-boat, with mechanical details and eerie sound design perfectly capturing the desperation of life beneath the waves. True to Nolimit City’s style, the studio amplifies everything fans loved while keeping the core formula intact.
Das xBoot 2wei! Core Gameplay: Diving into xNudge, xWays, and xBomb Action
The game begins with a 6-reel matrix configured in a 2-3-4-4-3-2 setup, offering 576 default ways to win. Nolimit City has made strides in the gameplay by shifting much of the action from the bonus rounds to the base stage.
The pay symbols are split between military green Royals and higher-paying crew members, including the cook, mechanic, and captain. Landing six high-paying symbols grants rewards ranging from 1x to 5x the bet.
| Symbol | 6 Matches | 5 Matches | 4 Matches | 3 Matches |
|---|---|---|---|---|
 | 5x | 3x | 1.75x | 1x |
 | 3x | 2x | 1.25x | 0.75x |
 | 2x | 1.5x | 1x | 0.5x |
 | 1.5x | 1.2x | 0.8x | 0.4x |
 | 1x | 0.7x | 0.5x | 0.3x |
 | 0.9x | 0.65x | 0.4x | 0.25x |
 | 0.8x | 0.6x | 0.4x | 0.25x |
 | 0.7x | 0.5x | 0.35x | 0.2x |
 | 0.65x | 0.45x | 0.3x | 0.2x |
 | 0.6x | 0.4x | 0.3x | 0.2x |
The game relies heavily on Nolimit City's signature xMechanics to increase the game area and potential payouts.
- xWays: These symbols appear on reels 2 and 5, transforming into the same paying symbol and revealing 2 or 3 instances, which expands the grid size.
- xNudge Wild: Depicted as a war medal, this 4-stacked symbol lands on reels 3 and 4 (or reel 4 during Periscope Up!), nudging to cover the entire reel. Crucially, the multiplier increases by +1 for every step taken, and if multiple xNudge Wilds contribute to a win, their multipliers are added together.
- xBomb: This symbol, shown as a naval mine, explodes after initial wins are evaluated, removing all symbols except Wilds and Bonus symbols. This explosion brings down a new set of symbols and increases the current global win multiplier by 1.

Key Features: Periscope Up! and Torpedo Builder Mechanics
We were absolutely blown away by the meticulous way the game's features were seamlessly incorporated into the submarine theme.
- Periscope Up!: This feature may trigger at random, increasing reel 3 to 8 positions high, literally modeling a rising periscope. If a special Periscope Wild lands and a torpedo launch is activated, hitting the target causes the Wild to expand and nudge downwards, improving the multiplier with each move.
- Torpedo Builder: This intricate mechanism uses an ocular above reels 5 and 6. When a full boat appears, the feature begins a 3-respin mode on reels 2-5, during which xWays and xWays Wilds (with values of +1, +2, or +3) drop into a horizontal Torpedo area. Once the spins conclude, these collected parts transform into xWays and Wilds with the accumulated instances. The possibility of triggering the Golden Torpedo Builder, which charges symbols with values of +8 or +88, offers massive potential.
Free Spins Tiers: Silent Hunter, Wolf Pack, and Ultimate Carnage
The mission never changes: hunt prey and don’t get spotted. The path to the highest prizes lies through the three progressive free spins rounds, which are triggered by landing 3, 4, or 5 Bonus symbols (the sonar image).
- Silent Hunter Spins (80x Feature Buy): Landing 3 Scatters triggers 8 spins. During this mode, the Periscope Up! feature is always active, and all multipliers derived from nudges and xBombs remain persistent.
- Wolf Pack Spins (250x Feature Buy): Landing 4 Scatters triggers 9 spins. The Torpedo area below the grid is active from the start and pre-loaded with four parts (value 2), which can be increased by corresponding symbols. The collected Torpedo values, along with xBomb multipliers, grow persistently throughout the round.
- Battle of Atlantic Spins (750x Feature Buy): Scoring 5 Scatters grants 10 spins, merging the high-potential mechanics from both Silent Hunter Spins and Wolf Pack Spins. Nolimit City stated that this final bonus round is designed to 'unleash ultimate carnage' by combining all features.
We noted that in all bonus modes, landing additional Bonus symbols awards 2 extra spins.
Maximizing Your Wins: Nolimit Booster and Strategic Buy Options
Given the game's high volatility, we found in our testing that leveraging Nolimit City’s specific features is key to strategic play, though these features can come with steep costs.
We observed that the Feature Buy options give direct access to the most lucrative bonus rounds. While the Battle of the Atlantic Spins is expensive at 750x the bet, the merging of persistent features from both Silent Hunter and Wolf Pack modes gives us the best view of the 59,999x max win through the periscope. In our tests of the game, we found that Wolf Pack mode consistently gave us the most significant wins.
For players seeking guaranteed action without the highest risk, the Nolimit Booster menu offers several options, such as triggering the Periscope Up! feature for 8x the bet or the Torpedo Builder for 20x the bet. We also noted the possibility of triggering the Golden Torpedo Builder feature for 4,500x the bet.
Best Nolimt City Alternatives to the Das xBoot 2wei! Slot
- San Quentin xWays delivers brutal, high-volatility action with an RTP of 96.03%. Its xWays features can unleash huge bursts of wins, and if everything aligns, the slot can pay up to an enormous 150,000× your stake.
- Disorder by Nolimit City leans into the eerie theme of madness and a mid-twentieth century mental asylum. The slot has high volatility, a max payout of 66,666x, and an RTP of 96.08%.

Final Verdict: Is Das xBoot 2wei! Worth Enlisting For?
Das xBoot 2wei! is a powerful sequel that does what a proper follow-up should: it takes a proven formula and intensifies it. The studio has provided another fun release with a long list of modifiers to explore. The genius lies in seamlessly integrating the complex features (Periscope Up! and Torpedo Builder) into the WW2 submarine theme, making them feel integral to the gaming area.
We appreciated that key mechanics are now available during standard spins, injecting more non-stop action into the base game. Crowning this new arrangement, the Battle of the Atlantic Spins merges everything into one packed bonus round, offering unexpected wins and immense possibilities for chasing that top prize of 59,999x the bet. For fans of the original, Nolimit City’s signature brutal themes and highly volatile chaos, this slot is a strong recommendation.
