Das xBoot

Plunge to the depths of the ocean in Das xBoot, the online slot from Nolimit City which dares to confront the psychological torment of the hit movie. You'll need nerves of steel to survive the claustrophobic conditions, surrounded by crewmates who don't have your best interests at heart. But there's an incredible prize waiting for those who have the courage to persist; a max payout of x55,200 will make it worth your while…

Players of a certain age will remember watching the gripping drama that captured the difficult conditions on a war submarine in excruciating detail. WIth some of the crew slowly descending into insanity and with supplies running low, it's a harrowing tale of the deep that enthralled more than just the usual war aficionados. But like many other film-themed slots, you don't need to have watched the movie to appreciate the gameplay. Surrender to the dark and gritty overtones, and take your place on the submarine as it hurtles into the deep.  

There are six reels on this slot which are laid out in a 2-3-4-4-3-2 configuration which is fluid depending on the stage of the game. There are no traditional paylines, but when the board is in its most basic form, there are 576 ways to win. This can increase to 75,712 ways to win when the board expands, so you'll need to be on your toes from the start! Play is accessible for low and high rollers with a betting range that runs from 0.20 to 100.00. Volatility is as high as you'll find anywhere, so you'll need to endure the conditions for a little longer if you want to claim the big wins. 

Lots of the game is set far below the surface of the water, where the rays of the sun are just a distant memory. With the industrial metal submarine in the background, and your grim-faced crewmates to accompany you, it's an epic mission that you're about to undertake. Some of the play is set above the waves, but the sights are no more welcoming. On the horizon, there are warships gunning for your elimination, and the sky's ablaze with a scorching red hue. 

The low pays are the playing card royals, a break from the submarine theme. The premium symbols are your crewmates, including a radio operator, chef, periscope lookout, engineer, and captain.

Submarines are notorious for not having much space, but there's an incredible amount packed into this vessel.  

The xWays symbol can land randomly on reels 2 and 5, providing up to 3 instances of the same symbol. If more than one ways symbol lands simultaneously, they'll all display the same one.  

The xNudge Wild is four rows high wild that not only substitutes for other symbols, but also nudges into view, so it's completely visible on the reels. Every nudge it takes pushes the wild multiplier up by +1.  

There is also an xBomb Wild, which increases the win multiplier by +1 before exploding to clear the reels of any symbols which aren't involved in a win. After explosion, the xBomb Wild converts to a simple wild, substituting for regular symbols. New symbols tumble onto the reels from above, filling the spaces and checking for new wins. 

The sonar scanner is the scatter, and if you land three on a single turn, you'll be rewarded with eight Silent Hunter Free Spins. Land four scatters, and you'll receive eight Wolf Pack Free Spins instead.  

Both of these free spins rounds include a myriad of fun features, including expanding reels, new wilds, win multipliers and more! There are so many different variations possible; the only way to discover exactly what's included is to play the game yourself! 

If you're desperate to get stuck into the free spins rounds but aren't having any luck landing the scatters, you can opt for the Bonus Buy feature instead. Silent Hunter Free Spins will cost x75, while Wolf Pack Free Spins cost x350 to play.

A war submarine doesn't sound like the most uplifting slot to play, but the theme is gripping and immersive. Even better, Das xBoot from Nolimit City has an incredible number of features that are guaranteed to keep every player addicted to the deep. With a substantial top payout and lots of bonus rounds, this is a slot that everyone should try whether you're a fan of the original film or not!
