Torpedoes in the Deep

Key takeaways

How Das xBoot 2wei! Works

Grid and ways

The grid runs 2-3-4-4-3-2 rows high, which creates 576 ways before any feature expansion. xWays symbols can split into 2 or 3 copies, and that raises the count during active spins. You can track the live total on the ways gauge at the left side of the screen.

The layout stays readable on desktop and mobile because the ways gauge, multiplier dial and Ocular remain visible around the reels. I like that choice, since Nolimit packs a lot of information into the interface. You don’t need to guess whether the ways count has changed.

Key Stat: The game starts at 576 ways, but xWays can push the count much higher during feature chains.

Wilds and symbols

The game has 16 symbols, including four Wild types. The regular Wild substitutes for everything except Bonus, while xNudge Wilds, xBomb Wilds and Periscope Wilds add extra jobs. You should treat Wilds as the main engine, not just helpers.

At a $1.00 bet, the captain pays $5.00 for six. The torpedo man pays $3.00, the porthole sailor pays $2.00, the radio operator pays $1.50 and the ship cook pays $1.00 for six. Low symbols pay less: A pays $0.90, K pays $0.80, Q pays $0.70, J pays $0.65 and 10 pays $0.60 for six.

The paytable tells you plenty about the game’s shape. Base wins can start small, but modifiers decide whether a spin matters. That design feels fair, though it can leave you staring at tiny returns for long stretches.

xNudge, xWays and xBomb Mechanics

Multiplier builders

The xNudge Wild lands only on reels 3 and 4. It stands 4 rows high, nudges until fully visible and adds +1 to its Wild multiplier with each nudge step. If more than one multiplier joins a win, the game adds them together.

The xBomb Wild also substitutes for everything except Bonus. When it joins a win, it removes symbol types outside the winning combination, adds +1 to the win multiplier before the collapse, then lets symbols drop and refill. That timing matters, because the multiplier improves the win before the board changes.

Around spin 35, an xBomb helped a small but useful $6.20 hit with a x2 multiplier. It lit up aces and jacks, then showed exactly why the mechanic can save dull base-game spins. Still, one neat collapse doesn’t hide how cold the base game felt.

Ways expanders

Theme & First Impressions

U-boat setting

A ways gauge sits on the left, and a dial shows the current multiplier. The Ocular above reels 5 and 6 looks like a lookout window, not just a feature meter. That visual choice helps you understand why boats, torpedoes and periscopes drive the game.

Das xBoot gives returning players the rough submarine identity, but this sequel feels denser and darker. The added feature pressure changes the mood from gritty to cramped. I prefer this version’s interface, though the screen can feel busy during feature teases.

Insight: The Ocular above the right reels acts like the submarine’s lookout point, which fits the torpedo-hunt setup.

Bonus atmosphere

Periscope Up!

Torpedo trigger

A Periscope Wild can land on reel 3 after the reel grows. Matching symbols must connect across reels 1 and 2 with that Wild on reel 3, then the torpedo launch starts. The setup sounds fussy, but the animation makes the requirement clear.

During my test, Periscope Up! fired at spin 37. The torpedo hit, the Wild grew up reel 3 and then nudged down. That sequence paid $11.84 with a x5 multiplier, which became one of the session’s few memorable base-game moments.

Hit or miss

Torpedo Builder

Building the tube

When the feature starts, reels 1 and 6 close. A torpedo tube appears under reels 2 to 5, and only torpedo parts can land there. You get 3 spins to build four parts before the launch decision.

Reels 2 and 5 can add +1, +2 or +3 xWays. Reels 3 and 4 can add +1, +2 or +3 xWays Wilds. If all parts fill, the torpedo launches and splits those reels by the collected sizes.

Torpedo Builder appeared several times during my 500-spin run. None of those results paid more than $19.20 on a single spin, so the feature felt more like a promise than a rescue. That’s a useful reality check if you expect every builder to explode.

Golden version

Bonus Rounds

Three bonus paths

Three Bonus symbols award 8 Silent Hunter Spins. Periscope Up! stays active, and each Periscope Wild nudge builds a persistent multiplier. Four Bonus symbols award 9 Wolf Pack Spins, with a pre-loaded torpedo tube under reels 2 to 5.

Wolf Pack parts leave Wilds behind as they detach. Every full boat in the Ocular launches a torpedo and loads another, which gives the round a much stronger pace. Five Bonus symbols award 10 Battle of the Atlantic Spins, combining both Periscope Up! and Wolf Pack-style torpedo features.

Strategy Insight: Battle of the Atlantic is the most loaded round on paper, but the $750 buy price needs a serious result before it feels comfortable.

Persistent multipliers

Bonus Buy Testing

Silent Hunter result

The buy menu priced Silent Hunter Spins at $80 on my $1.00 stake. It also showed Wolf Pack Spins at $250, Battle of the Atlantic Spins at $750 and Lucky Draw at $290. Boosters ranged from the $1.50 Bonus Booster to the $4,500 Golden Torpedo Booster.

I bought Silent Hunter once, and the card opened a pink activation window. The next spin charged $80, landed three Bonus symbols and showed the 8 Silent Hunter Spins screen. Several Periscope events appeared, which made the round feel busier than the payout suggested.

One torpedo hit grew the Periscope Wild up reel 3 with a x4 multiplier for an $8.00 spin. The round paid $35.20, then offered an Extra Spin for $15.00. I declined it, leaving a result under half the buy cost.

Wolf Pack result

Wolf Pack Spins cost $250, and this buy gave the guide’s strongest tested moment. The pre-loaded torpedo launched and split the middle reels into Wild stacks. That start immediately felt more promising than Silent Hunter, because the reels carried more active material.

On the second-to-last spin, launches and cascades climbed through 84, 120, 275 and past 414. One spin paid well over $400 across 332 ways. The full round returned $448.00 after I declined a $105.00 Extra Spin.

That result landed near 1.8x the buy price, which feels good but not outrageous for the cost. Nine to Five may appeal if you like Nolimit-style bonus-buy tension with a different setting, while this slot leans into layered submarine mechanics. I didn’t test Battle of the Atlantic, Lucky Draw or any booster.

Extra Spin Decisions

How it appears

The Extra Spin keeps multipliers and torpedo progress. It only appears when the cost is no more than the win, which makes the offer feel reasonable at first glance. You’ll notice the game framing it as one more chance with the same active setup.

The rules say the best return comes from declining it. That line matters more than the emotional pull after a tense round. I don’t mind the option existing, but I wouldn’t treat it as a default extension.

Warning: The Extra Spin can look cheap compared with the round total, but the game rules still point to declining as the best-return choice.

Why I declined

Silent Hunter offered one extra spin for $15.00 with the round total at $35.20. I declined because the round had already missed value, and adding cost didn’t fit the return logic. That choice felt dull, but it was clean.

Wolf Pack offered one extra spin for $105.00 after a $448.00 result. I declined again, even though the feature state looked more tempting. If you take the offer, you’re paying for hope at the most emotional point of the round.

RTP, Volatility & Our Test

Simulator projection

The SatoshiHero Slot Simulator ran at 95.94% return, very-high volatility and the 59,999x cap at my $1.00 stake. Its model used 1,000 spins per session. The simulated maximum payout frequency sat around 1 in 25 million rounds.

The median 1,000-spin session ended $107.20 down. The middle 90% of runs landed between $437.90 down and $669.50 up, which shows a wide session spread. About 14% of spins returned something, a feature-sized hit appeared roughly once every 54 spins, and a 100x win appeared about once every 816 spins.

Those figures don’t forecast your next session. They show how different session paths can look when the same math drives every run. I like the simulator here because it explains the cold streak better than any slogan could.

Warning: A very-high-volatility game can show multiple features and still finish sharply down if the bonus round doesn’t land.

Our 500-spin session

I played 500 spins at $1.00 in two autoplay runs of 250 with turbo on. My balance moved from $10,000 to $9,707.90, so the session finished $292.10 down. The graph looked close to a straight-line slide.

Base features did appear, but they didn’t rescue the run. Around spin 35, the xBomb helped a $6.20 hit. At spin 37, Periscope Up! hit for $11.84 with a x5 multiplier, and Torpedo Builder appeared several times.

No base feature exceeded $19.20 on a single spin. I never saw three Bonus symbols, which made the volatility feel harsh rather than thrilling. For a 59,999x ceiling, the dry base-game feel makes sense, but it won’t please players who need frequent reassurance from small wins.

The 95.94% RTP is the operator-published theoretical return, and one 500-spin live session doesn’t change that figure. Bonus-buy and booster RTPs sit slightly different from the base game by design, from 96.02% to 96.07% across those options. Simulator figures describe modelled session ranges, not guaranteed outcomes.

Final Verdict

Das xBoot 2wei! stands out because its submarine features link together with real mechanical depth. The drawback is clear: the base game can drain a balance while you wait for a proper bonus connection.

My Take

High-volatility slot regulars should expect long blank stretches, not steady comfort. The best moments came from Wolf Pack Spins, while the base game mostly showed how hard the math can bite. Keep stakes modest unless your bankroll can absorb several cold runs.

I like the way Periscope Up!, Torpedo Builder and xBombs share one harsh system. I don’t like how little the base game gave back across 500 spins, even with several feature teases. The $448.00 Wolf Pack result saved the testing mood, but it came from a $250 buy.

Das xBoot 2wei! is a strong pick when you want dense mechanics, not easy reassurance, and the numbers on this page are updated periodically.

Pros:

• 
  Deep Feature Engine: xWays, xBombs and torpedoes create meaningful reel changes.
• 
  Strong Wolf Pack Test: My $250 buy returned $448.00 through stacked Wild growth.
• 
  Clear Interface: Ways, multipliers and Ocular progress stay visible during play.
• 
  Distinct Theme: The rusting submarine setting gives every feature a clear purpose.

Cons:

• 
  Harsh Base Game: My 500 spins lost $292.10 without a bonus.
•

Best For: This slot fits patient bankroll managers, bonus-buy testers and Nolimit fans who enjoy complex, volatile engines. You’ll get the most from it if you can accept dry base stretches and judge features by real cost, not just animation noise.
