Das xBoot 2wei Slot (Nolimit City)

The Das Boot 2wei slot initially begins with 6 reels and 576 ways to win, with a 2x3x4x4x3x2 layout/formation. 3 or more matching symbols from left to right, on successive reels and starting from the leftmost reel will constitute a winning combination. Only the highest win per way to win will be awarded though.

With a 20p minimum bet per spin, the maximum spin value is £5 a spin in the UK (or up to £2 if you’re under 25). Simply click/press the ‘Coins’ icon to see all available stake options. Outside the UK, you can opt for Turbo Mode (quicker spin speed) and Autoplay (up to 1,000 auto spins).

The Das Boot 2wei RTP rate is 95.94%, with 65.85% from the base game and 30.09% from the bonus features. NLC has created 94.02% and 92.03% alternative RTP settings so check within the Paytable at your chosen slot site. The the Das Boot 2wei demo above uses the highest RTP setting.

With extreme volatility, the hit frequency rate is 21.75%: this means a win will land every 1 in 4.6 spins on average. To trigger any of the free spins features, this happens every 1 in 273 spins (again, on average).

Finally, Das Boot 2wei benefits from 59,999 x bet max wins: known as ‘Nein! Nein! Nein! Nein!’, it is higher than the 55,200 x bet max win potential in the first game. The max win probability is 1 in 25.3 million spins with your chances of winning 100 x bet or higher at 1 in 734 spins.

With a war theme, the Das Boot 2wei slot is the sequel to Das xBoot (released in September 2021). In this instalment, you join a crew that has been submerged (in a submarine) for over 4 years. They’ve been clearing sea mines, dodging enemy patrols and picking off destroyers, according to Nolimit City.

Since their first deployment, they’ve got a few upgrades (i.e. weapons) to become stealthier and deadlier than ever. Das Boot 2wei continues the mission of hunting prey and not getting spotted.

With virtually the same graphics as the original slot game, you head underwater where the setting is at the back of the U-boat. I love the enthralling and harrowing soundtrack which really sets the tone.

On the reels, you’ll see low-value A, K, Q, J and 10 royals. Then you have 5 members of the crew including the chef, signaller, mechanic, lieutenant and captain: the captain is the best-paying symbol, awarding 5 x your total bet for 6 in combination.

Das Boot 2wei benefits from several special symbols: they including a gold medal xNudge Wild, silver medal xWays, xBomb Wild, Periscope Wild, boat, golden boat and ship radar Bonus symbol. Their functions are described below in the ‘Bonus Features’ section.

Das Boot 2wei Mobile

Nolimit City produce all slot games using HTML5 technology. This means that Das Boot 2wei is compatible with desktop, tablet and mobile devices, including iOS and Android smartphones (with the latter playing out in Portrait Mode). To experience the game in all it’s glory, a laptop or PC is recommended.

Like its predecessor, the Das Boot 2wei slot has xNudge Wilds, xWays and xBomb Wilds in the base game. NLC has added a Periscope Up! extra and Torpedo Builder feature (with a golden version) that can lead to huge win potential. There are 3 free spins features with the Battle of the Atlantic Spins combining the Periscope Up! from the Silent Hunter Spins and Torpedo Builder from the Wolf Pack Spins for an all-action war.

xNudge Wild

Look out for the gold medal xNudge Wild: it appears 4-rows high and always nudges to appear fully visible. Every nudge increases the wild multiplier by 1. Only landing on reels 3 and 4, it will only appear on reel 4 during the Periscope Up! feature. All wild multipliers add to each other with the win awarded after being subjected to the total multiplier.

xWays

With the silver medal xWays symbol lands on reels 2 and 5, it will reveal a random paying symbol. 2 to 3 symbols in size, multiple xWays symbols landing on the reels will see all xWays symbols revealing the same randomly chosen symbol. xWays symbols also increase the number of ways to win.

xBomb

xBomb Wilds substitute for all symbols except Bonus symbols. Exploding all symbols types that are not part of a winning combination (except the Bonus and other wilds), the remaining symbols fall down on the reels with new symbols collapsing in to fill the empty positions.

With the xBomb Wild increasing the win multiplier by 1 before the collapse, the win multiplier is carried through to the Torpedo Builder, Silent Hunter Spins, Wolf Pack Spins and Battle of the Atlantic Spins features during a feature trigger.

Periscope Up!

In the Periscope Up! feature, reel 3 grows to 8 positions with a new Periscope Wild symbol possibly landing. If a Periscope Wild lands on reel 3 as well as connecting symbols on reels 1 and 2, a torpedo launch sequence initiates: a target is identified in the periscope and a torpedo is fired.

If it hits the target, the Periscope Wild grows to the top position and nudges down to the bottom position. In the process, a win multiplier is added for each nudge. If the target is missed, the Periscope Wild acts like a single wild symbols.

The Periscope Up! feature can trigger randomly in the base game and Wolf Pack Spins feature. In the Silent Hunter Spins and Battle of the Atlantic Spins features, it remains active throughout. However, the Periscope Wild won’t nudge over symbols revealed from the torpedo launch.

Torpedo Builder

In the base game and Silent Hunter Spins feature, the Torpedo Builder feature will activate if a full boat lands in the 2 symbol wide binocular position (above reels 5 and 6).

With a torpedo tube appearing under reels 2-5, only torpedo parts will land on those reels (reels 1 and 6 will be closed). You then get 3 respins to build the 4 parts of the torpedo:

• Reel 2 and 5: the torpedo parts drop a +1, +2 or +3 xWays symbol to the torpedo area. They activate once the torpedo is launched.
• Reel 3 and 4: the torpedo parts drops a +1, +2 or +3 xWays Wild symbol to the torpedo area. They activate once the torpedo is launched.

If all torpedo parts are filled, the torpedo launch sequence begins and xWays symbols are revealed behind the torpedo in the size of the collected parts, on each reel. On reels 2 and 5, they transform into paying symbols and split in the number of ways that were revealed from the torpedo parts (i.e. 1, 2 or 3). On reels 3 and 4, they transform to a wild and split into 1, 2 or 3.

Golden Torpedo Builder

If you land a golden boat in the binocular position (above reels 5 and 6), you will trigger the Golden Torpedo Builder feature. Applying in the base game and Silent Hunter Spins feature, torpedo parts only have values or +8 or +88.

In Base Game and Silent Hunter Spins, landing a golden boat in the Binocular will trigger Golden Torpedo Builder, where the Torpedo parts will only have values of either +8 or +88.

Free Spins features

Das xBoot 2wei comes with 3 free spins features. They are all triggered by the ship radar Bonus symbol, which can land on all reels:

Silent Hunter Spins

In the Silent Hunter Spins feature, the Periscope Up! feature is always active. Additionally, the Periscope Wild nudge gives you a persistent multiplier: it begins at 1x after the first nudge and increases by 1 with every nudge. The multiplier applies to the free spin in which the Periscope Wild lands and when the target is hit.

When an xBomb symbol lands, an xBomb Multiplier is awarded: increasing the multiplier by 1 for the remainder of the feature. All multipliers are added together before wins are paid out. Any Bonus symbols landing will give you 2 extra free spins.

Wolf Pack Spins

In the Wolf Pack Spins feature, a torpedo tube appears under reels 2-5: torpedo parts can land on these reels. Preloaded with xWays and xWays Wilds (size of 2 to begin with), torpedo parts detech from the reels and leave a wild in their place.

• Reels 2 and 5: torpedo parts drop a +1, +2 or +3 xWays symbol to the torpedo area, which become active once the torpedo is launched.
• Reels 3 and 4: torpedo parts drop a +1, +2 or +3 xWays Wild symbol to the torpedo area, which become active once the torpedo is launched.

When a full boat lands in the binocular, the torpedo launches. On reels 2 and 5, symbols transform into paying symbols and split in the number of ways collected from the torpedo parts. On reels 3 and 4, they transform into wilds (and split in the number of ways collected from the torpedo parts).

Once the torpedo launches, an identical torpedo is loaded: it can be enhanced further in the coming free spins. When an xBomb symbol lands, an xBomb Multiplier is awarded: it increases the multiplier by 1 for the remainder of the feature. All multipliers are added together before wins are calculated. Every Bonus symbol landing gives you 2 extra free spins.

Battle of the Atlantic Spins

In the Battle of the Atlantic Spins feature, the Periscope Up! feature from the Silent Hunter Spins and Torpedo Builder feature from the Wolf Pack Spins are active together, for ultimate carnage.

When an xBomb symbol lands, an xBomb Multiplier is award and increases the multiplier by 1 (for the remainder of the feature. All multipliers are added together before wins are calculated. 2 extra free spins are won by landing Bonus symbols.

Extra Spins

When any of the free spins features end, the Extra Spins feature can come into play. Any existing multipliers and torpedo tube progress will be kept. The cost is determined based on this. It will only be an option if the cost of the Extra Spin is less than or equal to the total win.

Das xBoot 2wei Slot

Rating: 4.5/5

Das Boot 2wei builds on its predecessor with a new Torpedo Builder, an extra all-action free spins game and higher max win potential of 59,999 x bet.

Chris Taylor

With the original game being so well-liked, Nolimit City has a challenge on their hands with the Das xBoot 2wei slot. For starters, it is almost identical graphically: using the same symbols, soundtrack and animations. As far as slot sequels go, fans of the first outing will be pleased NLC kept to the original formula.

In the base game, the gameplay remains almost intact: this is true in the case of xNudge Wilds, xWays and xBomb multipliers. However, Nolimit City has made it possible to trigger the Periscope Up! feature in the base game.

The Torpedo Builder feature is new in Das xBoot 2wei. Triggered by landing a full boat in the binocular position above reels 5 and 6, the aim is to fill torpedo parts which in turn starts the torpedo launch. With xWays and xWays Wilds added on reels 2, 3, 4 and 5, this can lead to a huge increase in the number of ways to win as well as multipliers. With the Golden Torpedo Builder feature, torpedo parts have a +8 or +88 value, making it much more lucrative potentially.

With 3 free spins features, the Silent Hunter Spins and Wolf Pack Spins feature work like in the original Das xBoot game. Nolimit City has added the Battle of the Atlantic Spins feature: this combines the Periscope Up! feature from the Silent Hunter Spins and Torpedo Builder feature from the Wolf Pack Spins for an all-action experience.

With the new additions, Nolimit City has managed to make Das xBoot 2wei much more intense, whilst still keeping the main essence of the original intact. Offering 59,999 x bet max win potential, it tops the original game marginally (55,200 x bet max wins).

In summary, the Das xBoot 2wei slot game builds on its predecessor with new bonus features, more intense action, an extra free spins feature and increased win potential.

If you want to play more war-themed slots, Nolimit City has plenty of options including Remember Gulag, Pearl Harbor, D-Day and Tanked. If you want something a little more light-hearted, ELK Studios’ Rabbit Royale and Print Studios’ Uncle Profit are battles you don’t want to miss.
