What Is Das xBoot 2wei!?

Four years after the original Das xBoot, Nolimit City's crew climbs back into their U-boat for a deeper, meaner mission. The wartime submarine setting, gritty crew characters and moody industrial audio all return intact, but the sequel pushes the underlying systems considerably further — this isn't a reskin, it's a genuine expansion of what made the original work.

The grid starts in an asymmetric 2-3-4-4-3-2 layout across 6 reels, producing 576 ways to win at base, but it's built to grow: as special modifiers land, the grid can expand all the way to a 2-4-8-5-4-2 configuration, dramatically increasing the number of active ways as the round develops.

xNudge, xWays and the Torpedo Builder

The xNudge Wild is 4 rows high and always nudges downward until fully visible, gaining +1 to its multiplier for every position it moves — land two in the same cascade and both multipliers add together before applying to the win. It normally appears on reels 3 and 4, though during Periscope Up! it's restricted to reel 4 alone. xWays symbols on reels 2 and 5 reveal additional matching symbols, expanding the number of active ways further still.

New to this sequel: the Torpedo Builder feature can now trigger directly in the base game, not just during free spins. Landing a full boat symbol in the binocular position above reels 5 and 6 starts filling torpedo parts, and once complete, the torpedo launches — with the improved Golden Torpedo Builder variant assigning each part a +8 or +88 value for a considerably larger payout when it fires.

Silent Hunter, Wolf Pack and Battle of the Atlantic Spins

Three free spins modes sit behind the scatter trigger. Silent Hunter Spins (3 symbols, 8 spins) keeps Periscope Up! permanently active throughout; Wolf Pack Spins (4 symbols, 9 spins) starts with a pre-loaded Torpedo Tube ready to fire; and Battle of the Atlantic Spins (5 symbols, 10 spins) merges both headline mechanics into what Nolimit City calls "ultimate carnage" — the mode most likely to produce the game's largest totals.

A wide Booster menu covers Bonus Booster, Periscope Up!, Torpedo Builder and Golden Torpedo Builder as direct buys, the latter costing a steep 4,500x for a guaranteed trigger. A 290x Lucky Draw weighs the odds 50/25/25 across the three free spins tiers.

RTP, Volatility and the 59,999x Ceiling

Default RTP is 95.94%, with 94.02% and 92.03% configurations also available — a slightly lower baseline than many recent Nolimit City releases, reflecting the concentration of return into the game's extreme top end. Volatility is rated the full 10 out of 10, and hit frequency of 21.75% translates to a win roughly every 4.6 spins, with free spins triggering naturally around once every 273 spins.

The max win — 59,999x, officially named Nein! Nein! Nein! Nein! — is a genuine step up from the original's 55,200x ceiling, and its published probability of roughly 1 in 25.3 million spins is, notably, more than twice as attainable as the original game's odds despite the higher headline number. Bets run $0.20 to $100 per spin.

Our Verdict

Das xBoot 2wei! is a confident, well-built sequel that respects what made the original memorable while genuinely deepening the systems underneath — bringing Torpedo Builder and Periscope Up! into the base game is a meaningful structural change, not just a cosmetic one, and Battle of the Atlantic Spins gives the bonus round a proper high point to build toward. The below-average 95.94% RTP is a real trade-off for that raised ceiling, and the dense mechanic stack will take genuine time to fully learn. For players who already enjoyed the original's submarine tension, this is a clear, worthwhile step up.
