Das xBoot Slot

You find yourself on a typical submarine from the Second World War. The base game is filled with XNudge Wilds, Wild multipliers, and xWays symbols. You can activate the Silent Hunter Bonus Round and the Wolf Pack Bonus Round at any time. Don't want to wait? Use the Bonus Buy option. It is included as usual, but not in all jurisdictions.

To start playing, you need to do just a few simple things:

• Launch the game (in demo mode or for real money)
• Open the menu to view the paytable and read the rules
• Click on the “Bet” button to select the stake size: from €0.25 to €100

That's all. Enjoy intense gameplay filled with bonus features!

This is where you have to deal with high volatility. This means that your submarine can sail quietly and unnoticed for a while, but sooner or later you will find yourself on a series of major victories. You also have to deal with adjustable RTP ranges, which is not very cool. The game comes with 96.03% or 94.04% RTP.

The provider develops all of its games using HTML5. This allows them to open up and work well on a wider range of devices, including tablets, smartphones, and desktops. You don't need to worry about the operating system you are using as their slots work fine with all of them. Play Das xBoot anywhere!

Silent Hunter

You need 3 Scatters to trigger the Silent Hunter feature. This gives you 8 free spins and you will see the 3rd reel expand into an 8-row high periscope reel. Landing the same symbols on reels 1 and 2 and Periscope Wild on reel 3, you activate the Torpedo Launch feature.

You will see enemy ships, and a torpedo is fired into one of them. If you manage to sink the target, the Periscope Wild symbol will expand to cover the entire 3rd reel. The global win multiplier increases by +1 for each torpedo attack trigger, and the periscope multiplier increases by +1 per push before the entire reel is covered.

Wild will not change if you miss the target and you will win 2 extra free spins for each additional Scatter.

Wolf Pack

The Wolf Pack feature is triggered when 4 Locator Scatter symbols land on the playing field. The torpedo tube will appear under reels 2-5. When Wild Torpedoes land on reels 2-5, a metal symbol xWays drops to help complete the torpedo, and each starts with 2x as a value. The value increases by +1 for each new torpedo dropdown menu, up to a maximum of 9x. Completing the torpedo by filling in all 4 positions triggers the launch of the torpedo and this reveals the xWays symbols you created. Reels 2 and 5 will turn into the number of xWays symbols you have collected, and positions 3 and 4 will turn into the corresponding number of xWays Wild symbols. Each torpedo launch increases the win multiplier by +1, and Scatter gives 2 extra free spins upon landing.

Bonus Buy option

Here you can instantly go to the bonus feature using the Bonus Buy option. UK players cannot do this, but if you are eligible, go ahead! In the purchased feature Silent Hunter or Wolf Pack, RTP increases to 96.56% or 96.57%, respectively.

Not ready to play for real money? Nolimit City has taken care of the availability of a Demo mode. You can use it right on this page by clicking on "Play Demo"! In this mode, you can familiarize yourself with bonus features, rules and spin the reels for free, but you will not be able to win real prizes.

The maximum win here is 55,200x the stake. Is this a lot? Yes, even for a high-risk game. Nobody says that it will be easy to win, but there are enough bonus features here and they are triggered quite often. Most likely, you will unleash the potential in the Wolf Pack Bonus Round of the highest level with xWays symbols, a progressive multiplier, and free spins.

We are delighted with this release! Nolimit City has done an incredible job and provided us with a high-quality slot on an unusual theme. Its atmosphere is very tense, but this is what we expected from a war-themed slot, right?

We also love the variety of bonus features. The Silent Hunter feature with 8-row high periscope reel and Torpedo Launch feature and the top tier Wolf Pack feature can bring you up to 55,200x the stake, which is a lot even for high volatility. Are you ready to compete for big wins by dealing with high volatility? Then this slot is for you!
