Back Under the Atlantic
This Das xBoot 2 slot review covers the sequel Nolimit City officially calls Das xBoot 2wei!, released in full on 16 December 2025 after a week of early access. The original Das xBoot arrived in 2021 and became a cult favourite. Its follow-up keeps the tense submarine setting and the brutal maths, then adds a lot more machinery.
The headline additions are a periscope that stretches one reel to eight positions and a torpedo you build piece by piece. Both feed into three free spins modes that get stronger as you land more Bonus symbols. The ceiling sits at 59,999x your stake.
It is a busy game, but the ideas connect well. Once you understand how the periscope and the torpedo work together, the whole thing starts to make sense, and it becomes one of the more rewarding Nolimit City slots to learn.
The Grid, Wilds and xMechanics
The six reels use a lopsided 2-3-4-4-3-2 shape, giving 576 ways at the start of a spin. Features can stretch the grid as far as 2-4-8-5-4-2, so the number of ways can climb quickly once things kick off.
The xBomb Wild substitutes for everything except the Bonus symbol and explodes to clear nearby symbols, raising the multiplier for the next collapse. The xNudge Wild is four rows tall and lands on reels three and four, nudging until it is fully visible. The xWays symbol only appears on reels two and five and reveals a stack of two or three matching regular symbols.
None of these are new to long-time Nolimit City players, but they fit this layout well. The narrow outer reels mean the middle of the screen does most of the work, which is exactly where the periscope lives.
Periscope Up! and the Torpedo Builder
Periscope Up! can trigger at random in the base game. Reel three grows to eight positions, and if connecting symbols sit on reels one and two, a torpedo launches. A hit makes the Periscope Wild grow to the top of the reel and nudge down, adding a multiplier with every nudge. A miss leaves a single Wild behind.
The Torpedo Builder triggers when a full boat appears in the Binocular. A tube opens under reels two to five, reels one and six close, and you get three spins to collect four torpedo parts. Finish the build and the torpedo launches, revealing and splitting xWays symbols across the grid.
A golden boat triggers the Golden Torpedo Builder instead, where parts are worth +8 or +88. That version is the base game moment to watch for. It is rare, but it is the closest thing this slot has to an instant spike.
Three Free Spins Modes
Three Bonus symbols trigger Silent Hunter Spins with 8 spins. Periscope Up! stays active the whole time, periscope nudges build a multiplier for that spin, and each xBomb adds +1 to a persistent multiplier that carries through the round.
Four Bonus symbols award Wolf Pack Spins with 9 spins. The Torpedo Tube is active from the start, pre-loaded with xWays and xWays Wilds. A full boat launches the torpedo, which then reloads an identical one, and xBomb multipliers persist. Periscope Up! can still trigger at random here too.
Five Bonus symbols unlock Battle of the Atlantic Spins with 10 spins. This mode combines the always-on periscope of Silent Hunter with the torpedo of Wolf Pack, and xBomb multipliers persist. Extra Bonus symbols in any mode add two more spins. This is the round built for the max win, and it plays like it.
Boosters, Bonus Buys and xTra Spins
Where they are allowed, Nolimit Boosters let you pay extra for specific outcomes. The Bonus Booster costs 1.5x the stake and guarantees a Bonus symbol. The Periscope Up! Booster costs 8x, and the Torpedo Booster costs 20x to guarantee the Torpedo Builder. At the top end, the Golden Torpedo Booster costs 4,500x and guarantees the golden version.
Direct bonus buys are also on the menu in markets that permit them, so check the in-game prices at your casino. At the end of a bonus round you may be offered an xTra spin, but only if its cost is no more than your total win, and your multipliers and torpedo progress carry over.
That last option is tempting after a good round. Our advice is to decide your limit before the bonus starts, because it is easy to give back a solid win chasing one more spin. The Das xBoot 2 demo is a good place to see how these choices play out.
Das xBoot 2 RTP, Max Win and Volatility
The Das xBoot 2 RTP is 95.94%, a touch below the 96% mark we usually like to see. Casinos can run different settings, so always check the info screen. Hit frequency is 21.75%, and free spins trigger about once every 273 spins on average.
The Das xBoot 2 max win is 59,999x your stake, and Nolimit City puts the odds at 1 in 25.3 million. Once the cap is passed, the round ends and the full amount is paid. Stakes run from 0.20 to 100 per spin.
Volatility is high, and Nolimit City rates it as extreme. Long cold runs are part of the experience. Slots are random and no system can predict a result, so keep stakes sensible, gamble responsibly and remember this game is for players aged 18+ only.
Our Das xBoot 2 Slot Review Verdict
Das xBoot 2wei! is a sequel that respects the original while giving it far more depth. The periscope and torpedo systems link together cleverly, the three bonus tiers feel clearly different, and the top mode has a real path to huge wins.
It earns our Masterpiece rating with a score of 9.8/10. The slightly lower RTP and the steep learning curve keep it from perfection, but for high-volatility fans it is one of the strongest Nolimit City releases of 2025. Try Das xBoot 2 free play in the demo on ReelRadar before you dive in for real.
Who should skip it? Players who want frequent, steady returns or a simple screen will find it hard going. Everyone else, especially fans of the first game, should give it time. The best moments here come from systems stacking on top of each other, and that takes patience to see.
