Das xBoot is an online slot developed by Nolimit City that begins with 576 winning ways that can increase up to 75,712.

The game comes with a wide range of features, including xWays, xNudges, free spins and more – with a top prize of 55,200x available.

Theme and Graphics

This is the first time that Nolimit City has created a branded slot game – so, while it has the same general style as other Nolimit City slots, there is a bit of a twist.

Das xBoot is based on a 1981 German war film called Das Boot, so the aesthetic and bonus features are very appropriate.

Impressive Aesthetic

In the Das xBoot free play slot, the game takes place in a submarine with symbols that feature various members of the vessel’s crew.

There is a great attention to detail in this game, with scatters designed to be radars, all sorts of gauges surround the reels and an atmospheric soundtrack playing as you spin the reels.

xNudge and xWilds in Das xBoot

xNudge and xWays are two popular mechanics that appear in Nolimit City slots often. In Das xBoot, you’ll find them both:


In Nolimit City’s Das xBoot slot, the xWays symbol can appear on reels 2 and 5. It works in the same way as it does in slots like San Quentin, where the xWays symbol reveals either 2 or 3 random regular symbols in a single position.

If more than one xWays symbol lands, all of them will reveal the same symbol.

xNudge Wilds

During the base game and Das xBoot free spins bonus, you’ll encounter the xNudge Wild. This is a 4-symbol high expanded wild symbol that will always nudge into place. So, whenever this symbol appears, it will always take up an entire reel.

xBomb Wild Multiplier

The xBomb is a wild symbol that substitutes for all other regular symbols. When it appears, it will explode and destroy all of the symbols that aren’t involved in winning combinations.

Then, new symbols fall into the reels. This also increases the win multiplier. If you trigger the bonus round when there is an xBomb present, the win multiplier will be carried over.

Free Spins and Bonuses

There are two bonus games that you can trigger during Nolimit City’s Das xBoot free play slot.

Silent Hunter Free Spins

This feature is triggered when you land three scatter symbols. During this bonus, the third reel grows to become 8 symbols high – and, the new Periscope Wild will be able to appear on it.

If you land a Periscope Wild with connecting winning symbols, then you’ll trigger a “launch sequence”. A torpedo will be launched and if it hits the target, your win multiplier will increase for the bonus. This is a sticky multiplier.

This will also cause the wild will expand and nudge to fill the reel. For every nudge, the win multiplier will increase, as well. This is not a sticky multiplier and will only apply to the current win.

During this bonus, xBomb Wild Multipliers can also land. This will also cause the sticky win multiplier to increase.

Wolf Pack Free Spins

When you land four scatters, you’ll trigger the Wolf Pack free spins round. Here, torpedo wilds are active:

  • When Torpedo Wilds land on the second and fifth reels, they will drop a +1 xWays symbol.
  • When Torpedo Wilds land on the reels, they will drop a +1 xWays Wild symbol.

These symbols are then dropped to the bottom of the screen. If they fill all of the blank spaces at the bottom of the screen, the torpedo will be launched:

  • The collected xWays will increase the number of ways to win on the second and fifth reels.
  • The collected xWays Wilds will not only expand the number of ways to win but fill the reel with wilds

Increasing multipliers are also active during this round. Their value will rise whenever a torpedo is launched or an xBomb Wild lands.

Das xBoot Slot Review

Das xBoot is feature-rich, unique online slot that gives players plenty of opportunities to win big. It’s likely to become a classic Nolimit City slot like Punk Rocker.

Complex Features

While we really enjoy playing Nolimit City’s Das xBoot slot, it is an incredibly confusing game when it comes to the bonus features. In both the Silent Hunter and Wolf Pack free spins round, the paytable doesn’t do the best job of explaining what’s going on.

That isn’t Nolimit City’s fault, however. The bonus features are just very complicated, and you really have to trigger the bonus round to understand. Alternatively, you can read up on them further up in the Bonuses section of our Das xBoot slot review; we go into a lot of detail to make sure you exactly how it works.

Impressive Winning Potential

There is a great opportunity for players to land some amazing payouts while spinning the reels on Nolimit City’s Das xBoot slot. The grand prize is worth over 50,000x and players are given plenty of chances to win big.

During the base game, the xNudge Wild symbols and xWays symbols combine to give you the chance to land great winning combinations. Then, things only get better during the free spins bonuses.
