This Das xBoot 2wei! slot review covers every mechanic on board the most technically complex submarine NLC has ever built — because the original Das xBoot was already a deep dive, and the sequel pushes every system further. Released in 2026, Das xBoot 2wei! stacks xBomb®, xWays®, and xNudge® Wilds onto a dynamically expanding grid, surrounds them with Torpedo Builder and Periscope Up!, and then offers three distinct free spin tiers culminating in Battle of the Atlantic Spins — where both the Periscope Wild multiplier system and the Torpedo cycle run simultaneously. The max win sits at 59,999×, and the path to it is one of the most layered mechanical sequences NLC has built. This review charts it in full.
Das xBoot 2wei! — Quick Stats
Das xBoot 2wei! base game — the asymmetric 2-3-4-4-3-2 diamond grid. The xBomb sea-mine Wild removes non-winning symbols and adds +1 to the win multiplier before the collapse. That multiplier does not reset on feature trigger — it carries forward into every free spin tier. xNudge Wilds nudge to full visibility on reels 3 and 4, adding +1 Wild multiplier per nudge position.
Das xBoot 2wei! Slot Review — Four Years Later, Same Mission
The original Das xBoot built its reputation on a specific promise: a submarine slot that actually behaved like a tactical simulation. Multiple win pathways. A grid that breathed. Features that stacked rather than fired in isolation. The sequel makes the same promise and then significantly extends the scope of what keeping it requires.
The additions in Das xBoot 2wei! aren’t cosmetic upgrades — they are structural. Periscope Up! expands reel 3 from 4 positions to 8 and introduces a torpedo-targeting mechanic that adds win multiplier per nudge position. The Torpedo Builder gives the base game and Silent Hunter Spins a completely separate win event embedded within the main bonus: a four-part collection system that launches a grid-transforming torpedo when completed. And Battle of the Atlantic Spins puts both Periscope Up! and Torpedo Builder into permanent simultaneous activation for 10 spins, creating a free spin mode that has no equivalent in the NLC catalogue for mechanical density.
What connects all of it is the xBomb. Every xBomb explosion in the game — whether in the base game, during a trigger, or during any free spin tier — adds +1 to the win multiplier and that increment persists for the remainder of the session. There is no reset. A base game spin that produces an xBomb chain immediately before scatter symbols land carries that multiplier directly into whichever free spin tier triggers. In a Das xBoot 2wei! slot review written for bonus hunters, that sentence is the most important one on this page.
Theme, Visuals & Sound
The sub crew is back and they have not been living comfortably. Four years submerged — the game’s intro text specifies the duration — has produced exactly the kind of weathered, barely-functional tension that makes the original’s aesthetic so effective. The cast is deliberately grotesque: a commanding officer who looks like he hasn’t slept since 1943, a green-tinged crew member who is clearly not well, and supporting characters who communicate a very specific kind of wartime desperation without a word of dialogue.
NLC’s war-horror visual palette is darker and more textured here than in the original. The underwater environment feels genuinely claustrophobic — the lighting is green-grey, the surfaces corroded, and the sense of pressure is embedded into the art style rather than applied on top of it. The Periscope Up! sequence breaks the grid for a moment to show the targeting periscope, the crosshairs finding a destroyer, and the torpedo detonating — each launch is a mini-cinematic. Sound design throughout matches: the xBomb mine detonation, the torpedo charge sequence, the multiplier counter ticking up. Every sound cue is functional as information, not just atmosphere.
Grid, Payouts & Base Game Mechanics
The base game grid is 2-3-4-4-3-2 — an hourglass or diamond shape with 576+ win ways in standard configuration. The narrowed outer reels (2 positions each) act as entry and exit points for ways-to-win combinations, with the widest coverage on reels 3 and 4 (4 positions each). This layout changes during Periscope Up!, where reel 3 expands to 8 positions, shifting the grid to 2-4-8-5-4-2 and dramatically increasing the ways to win through the third reel specifically.
The symbol hierarchy runs from card royals at the low end through submarine crew members and equipment up to the five character symbols. Winning combinations require matching symbols on adjacent reels from left to right. The xNudge Wild stacks 4-high on reels 3 and 4, always nudging to full visibility and contributing a multiplicative Wild multiplier — each nudge position adds +1 to the Wild multiplier, and multiple xNudge Wilds stack their multipliers additively before the win is calculated.
The base game hit rate — 1 in 4.35 spins — feels active. The xBomb triggers frequently enough to build multiplier context, and the Binocular above reels 5 and 6 creates a persistent reason to watch the right side of the grid. When a boat silhouette fills the Binocular, Torpedo Builder fires, and a sub-game within the base game begins.
Periscope Up! active — reel 3 expands from 4 to 8 positions, and the Periscope Wild enters from the top. If connecting symbols on reels 1 and 2 align with the Periscope Wild on reel 3, a torpedo is fired at the destroyer in the targeting scope. A hit sends the Periscope Wild nudging all the way from top to bottom, adding +1 to the win multiplier per nudge position — up to 8 increments if the full reel is traversed.
Features Explained
The X-Mechanic Trio
Periscope Up!
Reel 3 expands to 8 positions and a Periscope Wild symbol becomes available. When connecting symbols are present on reels 1 and 2 alongside a Periscope Wild on reel 3, a torpedo launch sequence initiates — a target appears in the periscope view. A hit causes the Periscope Wild to nudge from the top position all the way to the bottom, adding +1 win multiplier for each nudge position (maximum 8 on a full-reel traverse). A miss treats the Periscope Wild as a standard single Wild. In the base game and Wolf Pack Spins, Periscope Up! triggers randomly. In Silent Hunter Spins and Battle of the Atlantic Spins, it remains permanently active throughout. Note: the xNudge Wild does not land on reel 3 during Periscope Up! — only reel 4.
Torpedo Builder
Triggers in the base game and Silent Hunter Spins when a complete boat silhouette fills the Binocular above reels 5 and 6. A Torpedo Tube appears beneath reels 2–5, and only Torpedo parts can land on those reels for 3 spins (reels 1 and 6 close). Parts on reels 2 and 5 contribute xWays symbols of size +1, +2, or +3 to the torpedo. Parts on reels 3 and 4 contribute Wild symbols of size +1, +2, or +3. If all four parts are collected before the 3 spins expire, the torpedo launches — xWays symbols reveal on reels 2 and 5 at the collected size, and Wilds reveal on reels 3 and 4 at the collected size. Any xBomb multiplier active when the torpedo launches is carried forward into the resulting win calculation.
Golden Torpedo Builder
Triggered by a golden boat (rather than a standard boat) in the Binocular. The Torpedo Builder operates identically, but all parts can only have values of either +8 or +88 — no standard +1/+2/+3 parts are possible. A fully-loaded Golden Torpedo with four +88 parts launches a 352-position combined symbol event across reels 2–5. The Golden Torpedo Booster at 4,500× per spin guarantees this trigger — it is the game’s most extreme base-game bet mode and content territory for most players, but it establishes the theoretical upper range of Torpedo Builder outcomes.
Torpedo Builder mid-collection — the torpedo tube sits beneath reels 2-5 as parts drop in over 3 spins. Reels 2 and 5 contribute xWays parts (size +1/+2/+3) that transform into symbol clusters on launch. Reels 3 and 4 contribute Wild parts of equivalent sizes. In Wolf Pack Spins, the tube is pre-loaded and any full boat in the Binocular triggers an immediate launch, then reloads — producing multiple torpedo events within a single bonus session.
Das xBoot 2wei! Slot Review — The Three Free Spin Tiers
Three Scatter symbols trigger 8 Silent Hunter Spins. Four triggers 9 Wolf Pack Spins. Five triggers 10 Battle of the Atlantic Spins. The progression isn’t just spin count — each tier activates a different combination of the game’s feature architecture. Understanding what each tier runs and what it doesn’t is essential before choosing a buy.
Silent Hunter Spins — Periscope Dominance
Periscope Up! runs permanently. Reel 3 stays at 8 positions throughout all 8 spins. The Periscope Wild nudge builds a persistent multiplier: each successful torpedo hit adds multiplier increments that stay active for that specific spin (not carried between spins in this tier, unlike xBomb). An xBomb landing during Silent Hunter Spins adds +1 to the win multiplier for the remainder of the bonus — those increments do persist between spins. Additional Bonus symbols landing during the bonus award +2 extra spins.
Hunter’s note: In Silent Hunter Spins, the Periscope Wild nudge multiplier applies only to the spin where the hit lands. An 8-nudge Periscope Wild traversal adds ×8 to that spin’s multiplier — but the next spin starts from whatever xBomb multipliers have accumulated. The path to the highest Silent Hunter outcomes is therefore: multiple xBomb explosions building a persistent base, then a full Periscope Wild traverse landing on a high-symbol-value spin.
Wolf Pack Spins — Torpedo Dominance
The Torpedo Tube is pre-loaded with xWays and xWays Wilds at size ×2 at the start of Wolf Pack Spins. No waiting to collect parts — the tube is ready to fire immediately. Any time a full boat lands in the Binocular, the torpedo launches in its current state. Torpedo parts that land on reels 2–5 during the bonus detach from the reels (leaving a Wild in their place) and add to the tube’s current payload, enhancing the next launch. After each launch, an identical torpedo is loaded from scratch and can be further enhanced before its own launch. This means a 9-spin Wolf Pack session can deliver multiple torpedo events, each with an increasingly loaded payload if parts arrive quickly.
Battle of the Atlantic Spins — Both Systems, Simultaneously
This is the reason the 750× buy exists. Battle of the Atlantic Spins runs both Periscope Up! (permanent, as in Silent Hunter) and Torpedo Builder (cycling, as in Wolf Pack) at the same time for 10 spins. Every spin has reel 3 at 8 positions, the targeting scope active, and the torpedo tube loading simultaneously. An xBomb explosion adds +1 persistent multiplier. A Periscope hit adds its nudge multiplier to that spin. A torpedo launch adds its xWays/Wild grid transformation. These are not mutually exclusive — they stack on the same spin. A spin where an xBomb fires, the Periscope Wild nudges four positions through a hit, and a torpedo launches with a +3/+3/+3/+3 payload is a single game state that Das xBoot 2wei! is mechanically capable of producing.
The full Nolimit Bonus menu — three free spin tiers (80×, 250×, 750×) plus Lucky Draw at 290×. Below: four Nolimit Boosters covering different base-game enhancements. The Golden Torpedo Booster at 4,500×/spin is extreme content territory — the three standard free spin buys and the Lucky Draw are the practical options for bonus hunters.

🎯 Bonus Hunt Verdict
Why it earns Tier A+: Three mechanics that matter specifically in a hunt context: first, the xBomb multiplier carryover — any xBomb chain during the trigger spin enters free spins with an elevated baseline, giving natural triggers a genuine advantage over clean buys. Second, Wolf Pack Spins’ pre-loaded torpedo tube means every 250× buy starts with Torpedo-ready conditions rather than requiring parts to arrive before the first launch. Third, Battle of the Atlantic’s dual-system activation is the only mode in the NLC 2026 catalogue where two independent multiplier/way-expansion systems overlap — the ceiling difference between a well-loaded Battle of the Atlantic session and a standard free spin is categorical, not marginal.
Recommended buy: 250× (Wolf Pack Spins) is the hunt standard. The pre-loaded torpedo tube eliminates the cold-start problem that affects many collectors-style features, and the continuous reload cycle means even a bonus with modest Periscope activity still has multiple torpedo events. The 290× Lucky Draw is worth a dedicated slot in hunts where you want buy variance — you’re paying 40× more for a 25% shot at Battle of the Atlantic, which has a very different ceiling profile. On pure expected value per bet unit, the Lucky Draw is mathematically interesting in exactly the same way the Duck Hunters: Happy Hour 235× draw is.
The xBomb carryover angle: This is the Das xBoot 2wei! mechanic that most hunters underutilize when buying in. If you are spinning naturally — even with the 1.5× Bonus Booster running — watch for xBomb chains near a trigger event. An xBomb explosion that builds a ×3 or ×4 win multiplier in the base game, followed by scatters landing on the same or immediately subsequent spin, enters your free spins with that multiplier intact. A 250× Wolf Pack session that starts at ×1 versus ×3 is not the same session. Log the starting xBomb multiplier in each bonus — the Bonus Hunt Tracker notes field is the right place for this data across a series of hunts.
Extra Spin evaluation: Das xBoot 2wei! preserves not only multipliers but also the Torpedo Tube state (and its progress) when an Extra Spin is offered after Wolf Pack or Battle of the Atlantic Spins. If your bonus ended with a partially-loaded torpedo tube and an accumulated xBomb multiplier of ×4 or higher, the Extra Spin represents preserved strategic state, not just a free spin. Calculate before declining — this is one of the cases where the Extra Spin has genuine value beyond what the surface cost suggests.
Log xBomb starting multipliers, torpedo cycle counts, and full session ROI for Das xBoot 2wei! across your entire hunt history.

- Mechanical complexity is a learning curve — significant depth to understand before buying in blind
Das xBoot 2wei! Slot Review — Final Verdict
Four years submerged and the crew came back with something genuinely more dangerous. Das xBoot 2wei! isn’t a reskin or a ways-expansion of the original — it is a more mechanically complete game. Periscope Up! adds a mid-spin targeting event with a direct multiplier payoff. Torpedo Builder adds a collection mechanic with a variable-magnitude explosive outcome. Battle of the Atlantic fuses them. The xBomb multiplier carryover ties it all together with a mechanic that rewards hunters who pay attention to base-game spin state before triggering.
The 9.2/10 rating and Tier A+ designation reflect both mechanical quality and hunt-specific utility. The 250× Wolf Pack buy offers excellent value-to-ceiling ratio. The 290× Lucky Draw adds legitimate variance optionality. The 750× Battle of the Atlantic is the highest-ceiling buy in the NLC 2026 catalogue for the investment. And the Extra Spin mechanic — which preserves torpedo tube state in addition to multipliers — is the best-designed Extra Spin offer NLC has shipped.
For hunters who tracked the original Das xBoot: everything you knew still applies, and there is materially more to know now. This review covers the new mechanics exhaustively. The rest is in the sessions.

Das xBoot 2wei! — Frequently Asked Questions
What is the max win in Das xBoot 2wei!?
The maximum win is 59,999× the total bet — NLC calls this cap “Nein! Nein! Nein! Nein!” It is reached through Battle of the Atlantic Spins with both the Periscope Wild nudge multiplier and a fully-loaded torpedo launch combining under a high xBomb-stacked win multiplier carried forward from the trigger. Probability is approximately 1 in 25,300,000 spins at the 95.94% RTP version.
Does the xBomb multiplier carry over into free spins?
Yes — this is one of the most strategically significant mechanics in Das xBoot 2wei! Any xBomb multiplier built during the base game at the moment of scatter trigger is carried forward into the Torpedo Builder, Silent Hunter Spins, Wolf Pack Spins, and Battle of the Atlantic Spins. There is no multiplier reset on feature entry. An xBomb chain on the trigger spin directly improves every win calculation throughout the resulting bonus.
What is the best bonus buy in Das xBoot 2wei! for a bonus hunt?
Wolf Pack Spins at 250× is the recommended hunt standard — the pre-loaded torpedo tube provides immediate launch potential without requiring parts to collect first, and the continuous torpedo reload cycle provides multiple ceiling attempts per session. The 290× Lucky Draw is a strong alternative for variance, offering a 25% chance of the 750× Battle of the Atlantic tier. Battle of the Atlantic at 750× is the ceiling-hunter option for rescue plays.
What is the difference between the three free spin tiers?
Silent Hunter Spins (8 spins, 80×) runs Periscope Up! permanently — the Periscope Wild nudge builds a spin-specific multiplier on successful torpedo hits. Wolf Pack Spins (9 spins, 250×) runs the Torpedo Builder in continuous cycle mode with a pre-loaded tube — boats in the Binocular trigger immediate launches and reload. Battle of the Atlantic Spins (10 spins, 750×) runs both Periscope Up! and Torpedo Builder simultaneously, with xBomb providing a persistent +1 multiplier in all three modes.
What RTP options does Das xBoot 2wei! have?
Three RTP variants: 95.94% (standard), 94.02% (DX1), and 92.03% (DX2). The base/bonus split is extreme — 65.85% of return in base game and 30.09% in bonus mode, meaning the game’s value is heavily concentrated in the bonus rounds. Always verify the game information panel at your casino confirms 95.94% before playing. DX variants circulate widely across European operators.
How does the Extra Spin work in Das xBoot 2wei!?
An Extra Spin can be offered after any of the three free spin tiers end. Crucially, it preserves all existing multipliers for all bonus modes, and for Wolf Pack and Battle of the Atlantic Spins it also preserves the Torpedo Tube’s current state and progress. The Extra Spin is only offered if its calculated cost is less than or equal to the total win from the bonus. It is one of the best-value Extra Spin designs in NLC’s catalogue precisely because it locks in accumulated torpedo tube and multiplier state.
