Das xBoot Slot Review (Nolimit City)

Be prepared to test your grit in another extreme-graded Nolimit slot, Das xBoot!

The game is based on the 1981 West German war movie, Das Boot, which follows a crew on a submarine in the Battle of the Atlantic. With a whopping three of the studio’s mechanics featured in this game, the xNudge, xWays and the xBomb, plus up to 75,712 ways to win, it’s certainly not a game with a flat learning curve. But this ain’t no regular war-themed slot but one that can get you a medal of honour worth up to 55,200x bet. That’s certainly not less mental than their previous slot.

Das xBoot will be out from 14th September 2021 at recommended and tested Nolimit City slot sites like Mr Green.

Up to 75,712 Ways to Win

Das xBoot has an asymmetrical reel structure similar to Deadwood. It has 6 reels with 2-3-4-4-3-2 symbols to begin with. That’s 576 ways to win by default, which can increase all the way up to 75,712 with xWays.

xWays Symbol

The xWays mechanic is a signature feature of Nolimit that started 2021 with a bang following the release of San Quentin.

It appears among 10 other regular and stackable symbols, but only on reels 2 and 5. Each time you catch the xWays symbol, it will reveal a random regular symbol of 2 to 3 symbols high. Each regular symbol can pay up to 20x bet or more with the help of the xNudge Wild.

xNudge Wilds will always nudge to full reel.

Just like in Deadwood, the xNudge Wild symbol in Das xBoot is a 4-high Wild symbol that always nudges to full reel. Each nudge that will take it to cover the entire reel will increase the win multiplier by +1. But unlike Deadwood, in this submarine-themed slot, it can land only on reels 3 and 4. That is in the base game at least.

xBomb Wild Multiplier

Two xBomb Wilds means that all wins will be tripled.

Another way of getting some more juice from this marine slot is with the xBomb feature, which was first introduced in the Fire in the Hole slot. When the xBomb Wild appears, it explodes all symbols that are not part of a winning combo, except for the Bonus and other wild symbols. Each explosion also increases the win multiplier by +1.

Should you also get 3 or 4 Bonus symbols, the multiplier will be carried forward to one of the two free spin bonuses with 8 initial rounds each to start with.

Silent Hunter Spins Bonus

Enter Das xBoot’s most frequent bonus feature – Silent Hunter Free Spins.

For 3 Bonus symbols, you’ll get 8 spins and some special features to boot. Watch as reel 3 converts into a periscope by growing from 4 to 8 symbols high. Another way of looking at it is that the reel setup will turn from a fist look to a middle finger look, with an extra pinkie.

Periscope Wilds can reward big time.

With this new setup, a Periscope Wild symbol will become available, which can activate a torpedo launch. To initiate the sequence, you need matching symbols on reels 1 and 2, with the third reel turning into a hotspot for the special wild. If you manage to catch one, you’ll witness a torpedo launch with the exact percentage of a hit and miss. If you hit a warship, you’ll activate the Periscope Wild, which will nudge from as high as it appeared, increasing the multiplier with each drop like the xNudge Wild. This usually results in an oversized multiplier (see screenshot above) and a frequent big win. Likewise, you’ll get a +1 multiplier for the remainder of the bonus too.

For each Bonus symbol, you’ll also get +2 spins, which also holds true for the more advanced bonus, the Wolf Pack.

Wolf Pack Spins Bonus

Adding a better bonus on top of a regular one is a tradition that Nolimit City slots fans have come to like. Das xBoot is not an exclusion, hence for 4 Bonus symbols, you’ll earn yourself much grosser Wolf Pack Spins with a special torpedo under the reels 2-5.

Each time you land a Torpedo Wild, it will drop either a regular xWays symbol (reels 2 and 5) or an xWays Wild (reels 3 and 4) into the torpedo below. Only once the torpedo gets filled with these xWays symbols will it unleash them all at once. Depending on the xWays number, they will split up into up to 9 symbols each. This extends reels 2—5 and as a result can generate crazy wins that can end the bonus prematurely, at the maximum payout.

This can happen multiple times during the game, increasing the overall win multiplier by +1 along the way. That’s in addition to any xBomb symbols, which also add their own share to the main multiplier and +1 xWays if they happen to drop when the torpedo launch sequence is activated!

Bonus Buy

If you happen to play this game outside the UK then you’ll also have the chance to buy either one of the free spin bonuses for a fixed cost. That’s a 75x bet for the Silent Hunter Spins. Wolf Pack Spins are much rarer so the 350x price tag or at least 87.50 credits will be needed to activate them at your command. Go ahead and try both bonuses in free play to get a sense of their potential.

👍 Tip: The RTP increases from 96.03% to 96.57% in the Silent Hunter Spins and to 96.56% in the Wolf Pack Spins bonus.



Editor's rating:

Das xBoot is not a game that many players would relate to. But that doesn’t seem to bother Nolimit City even a little as they seem to be on a mission to stand out from the crowd with unorthodox themes and make fun of the traditional development approaches that permeate online casino games. The move away from charming graphics into the uncharted territory that no other developer dares to take go in the realm of slot themes is nevertheless an approach that I welcome and encourage. That is, as long as it’s done right, which so far Nolimit has not failed with its deliberate harsh artistic style of design.

Neither is it a fast slot to learn. It takes some practice to get hold of all the features and even then, bonuses tend to be short-lived and the base game is not exactly where you want to end up with. As for the fans of high-volatility slots who know the drill and are prepared to hold their breath as if in a silent running mission, the complexity which comprises three x-features and free spins may soon be greeted with “das gold des roter teufel”. For the less tolerant, feature buys will most likely be the only way of seeing what this Boot is really capable of.

Viel Glück!
