Das Boot is a film released in 1981 known worldwide for receiving excellent reviews from critics and fans and is considered one of the best and most expensive films ever made in Germany. It is based on the 1973 book written by Lothar Gunther Buchheim. Buchheim describes his experiences aboard the German submarine U-96 in the treacherous waters of the Atlantic Ocean during World War II. Now, based on the movie Das Boot, Nolimit City released the slot Das xBoot in September 2021. This game provider did an outstanding job in all aspects of the game. Moreover, the maximum prize can reach up to 55,200 times the placed bet. However, the possibility of obtaining such an outstanding win is balanced by a very high volatility.

The Das xBoot slot has 6 reels in a 2-3-4-4-3-2 configuration and offers 576 pay lines. Thanks to the game’s features, bettors can end up spinning for a maximum of 75,712 ways to win.

The submarine crew members are on display as the 5 premium symbols of this slot, along with the symbols 10, J, Q, K, and A. In the game, you will meet the chef, the radio operator, the engineer, the periscope operator, and the captain.

The latter is the top-level symbol, paying 20 times your bet for 6 appearances, while the other symbols pay between 0.88, 3, and 6 times your bet for the same number of appearances.


The xNudge and xWays mechanics are very popular and appear frequently in slots developed by Nolimit City. Das xBoot is no exception:

xWays – In Das xBoot, the xWays symbol can appear on reels 2 and 5. In this feature, 2 or even 3 randomly chosen paying symbols will be revealed. All xWays symbols that land on the reels will reveal the same random symbol, which in turn also increases the number of winning ways.

xNudge – The xNudge stacks 4 rows high and shifts into place each time it lands. The wild multiplier increases by +1, and the respective symbol will appear exclusively on reels 3 and 4 of the base game. So, every time this symbol appears, it will always expand on the whole reel.

xBomb – The xBomb symbol is a wild symbol that triggers the explosion of all the other symbols on the reels that are not involved in winning combinations. Afterwards, new symbols will land on the respective reels. This also increases the prize multiplier.


Sonar Scatters – Getting 3 or 4 Sonar Scatters activates 8 Silent Hunter Free Spins or 8 Wolf Pack Free Spins. Both rounds play out differently and allow players to expand the grid size and benefit from 2 additional Wild symbols for free spins.

In the Silent Hunter Free Spins, reel 3 grows 8 positions high (like a periscope). This allows new wilds to land on the fields. If matching symbols land on reels 1 and 2, with a Periscope Wild on reel 3, a torpedo launch sequence occurs, and the win multiplier increases by +1. Finally, any scatter in sight adds +2 additional free spins.

On the other hand, in the Wolf Pack Free Spins a torpedo tube appears below reels 2-5. When new torpedo symbols appear on these reels, an xWays symbol will be dropped in this area. These xWays symbols start at x2, increasing by +1 for each subsequent torpedo wild that hits thereafter, up to a maximum of x9. Similarly, scatter symbols award +2 additional free spins.

Silent Hunter free spins pay 75 times the bet and have an RTP of 96.57%, while Wolf Pack Spins pay 350 times the bet and have an RTP value of 96.58%.

The frequency and number of wins depends on the volatility of the game. Players tend to win much more often smaller prizes playing slots that have low volatility. On the contrary, if the volatility is high, players do not win often, but, when they do, they usually earn big sums.

We can say with certainty that Das xBoot is a high volatility slot, with an RTP of 96.05%, which in turn has a payout frequency of 22.07%.

As with many Nolimit City slot games, bets range from €0.20 to €100 per spin.

In Das xBoot, the game takes place in a submarine with symbols representing various crew members. One thing to note is that Nolimit City focused on minute details: The scatter symbols are radars, the reels are surrounded by all kinds of gauges and while you spin the reels an exciting soundtrack plays in the background.

Das xBoot is the team’s first example of a nautical-themed release. We think that they have done a fantastic job! With 3 main features in use (xWays, xNudge, and xBomb), Das xBoot does an impressive job of not being too busy.

The xBoot slot takes us to the depths of the sea, where the submarine lies hidden, lurking and searching for long-lost treasures. The sound effects give the game an unforgettable vibe.

The slot is based on the 1981 German movie Das Boot. This particular movie was nominated for 6 Oscars and has won countless international awards.

As the game can be a bit complicated to grasp at first, we would like to give you a small guide to start playing this excellent slot:

– First of all, you have the dollar sign “$”. By clicking on it, you can bet between €0.20 and €100 per spin.

– By clicking on the “Speaker” symbol, you can make sound adjustments.

– By clicking on the “Lightning” icon, you will be able to modify the speed of the game.

– The “Play” button will be very important while playing. In the autoplay menu you will be able to set the limits of losses and winnings.

Winning combinations are created by gathering three or more identical symbols. The game starts with 576 lines, but you can increase the number of them by getting xWays symbols.

The graphics of this Nolimit City title have a spectacular retro comic quality, representing, without a doubt, the German movie. Set at the bottom of the sea with the submarine in the background, the symbols look hand-drawn, which adds to the adventurous atmosphere. You will also notice the suspenseful soundtrack being very intense and even a bit creepy at times, which fits the war-like atmosphere perfectly.

The symbols on the reels include lower values A, K, Q, J, and 10. The highest value symbols are the 5 crew members.
