How Das xBoot Works

Ah..., a slot machine from Nolimit City, a cheerful, familiar world with simple features... or the exact opposite! Go to the depths and board the submarine from one of Germany's most famous feature films: Das Boot. Activate your sonar and fire your torpedoes to sink enemy ships, the Kapitanleutnant might just reward you with the jackpot!

The newest slot machine, Das xBoot, was released on September 10, 2021. You will find it in all online casinos offering the provider of the moment: Nolimit City. Its payout ratio (RTP) is quite high with 96.03% in base game and 96.57% when buying the bonus, but it is its volatility and especially its winning potential that are impressive. Like most of Nolimit City's slots, Das xBoot is extremely volatile, you can also win up to 55,200 times your starting bet. This maximum ratio is theoretically produced once every 60 million spins. The starting grid of Das xBoot has a rather special starting format with 6 reels consisting of 2, 3, 4, 4, 3 and 2 symbols respectively. This grid can be modified and enlarged thanks to the different features in the base game or during one of the free spins bonus. Indeed, several features are present in the base game of Das xBoot :

  • xNudge Wild: represented by a gold medal, in addition to replacing any other paying symbol, this Wild nudge (shifts) to occupy its entire reel. For each move, +1 is added to its multiplier;

  • xWays: Represented by a silver medal, the xWays symbol randomly turns into a pay symbol by multiplying its number of ways between 2 and 3. It can only appear on reels 2 and 5. If multiple xWays symbols appear on the grid at the same time, they all take on the same symbol;

  • xBomb Wild Multiplier: Represented by an underwater mine, the bomb explodes all symbols that are not part of a payline to create a cascade of new symbols. The win multiplier increases by +1 after each bomb explosion. After it takes effect, it reverts to a simple wild and replaces any symbol.

The different symbols in Das xBoot

In addition to the Wilds, xWays and the Sonar Scatter, there are 10 symbols in Das xBoot and they are classified into two categories according to their rarity:

  • High value symbols, otherwise known as premiums, are represented by the submarine crew. The Kapitanleutnant pays 20x the starting stake for 6 ways while the chef pays 3.2x the stake for the same number of ways;

  • Low value symbols are called common symbols. They are represented by the high values of a deck of cards (10-J-Q-K-A) and pay between 1.4x and 2.8x the starting bet for 6 ways.

Below are the potential payouts for a €1 bet.

The different connections in Das xBoot

There are many different ways to connect to the game at Das xBoot. Indeed, there are no predefined paylines in this slot machine. You have to line up identical symbols on adjacent reels. This way system is becoming more and more common and is quite simple to understand. Connections are made from left to right with a minimum of 3 reels having an identical symbol. On the starting grid, the number of ways is limited to 576 while it can reach up to 75,712 ways during the free spins bonus. The image below can help you understand this system of connections with examples that pay and examples without valid connections.

How the Das xBoot bonus works

Getting 3 or 4 Scatter symbols on a single pay spin triggers the Silent Hunter and Wolf Pack bonus symbols respectively in the Das xBoot slot. These bonus symbols can only appear on reels 2-5. During Silent Hunter Spins, the 3rd reel expands to 8 rows and a new Wild appears on the same reel: the Periscope Wild. If you manage to make a connection between reels 1 and 2 in addition to getting a Periscope Wild on the 3rd reel, an animation is triggered: you aim through the periscope and fire a torpedo at an enemy ship. Your chances of success are shown on the screen. If you succeed in sinking the target, the Wild Periscope nudges to occupy its entire roll. Its multiplier increases by +1 for each move. The total win multiplier increases by +1 for each target hit by your torpedo.

The win multiplier retains its value for the duration of the free spins after being enhanced by the xBomb Wild symbol. All the different multipliers are added together before multiplying the winnings. Each Scatter symbol that appears on the grid during the bonus grants you 2 additional free spins. Silent Hunter Spins can be purchased for 75 times the original bet with a maximum bet of €25 per spin. During Wolf Pack Spins, a torpedo is placed below reels 2-5 while the grid retains its basic format. Torpedo Wilds can then appear on these reels. When a Torpedo Wild appears on reels 2 and 5, it adds a +2 xWays symbol to fill the torpedo under the grid. Each new Wild Torpedo then adds +1 xWays to a maximum of 9 per cell. When a Torpedo Wild appears on reels 3 and 4, it adds a +2 xWays Wild symbol to fill the torpedo under the grid. Each new Torpedo Wild then adds +1 xWays Wild to a maximum of 9 per cell. When all parts of the torpedo are filled, it is then ejected, revealing the xWays and xWays Wild symbols and attaching them to reels 2, 3, 4 and 5.

On reels 2 and 5, the xWays turn into a random symbol with a number of ways depending on the collected Torpedo Wild symbols. On reels 3 and 4, the Wilds are cut to offer a number of ways depending on the number of torpedoes collected beforehand. Each time a torpedo is launched, the total win multiplier is increased by +1 for the remainder of the bonus. If an xBomb Wild symbol appears at the same time as a torpedo share, the torpedo share wins an additional +1 xWays. The various multipliers add up to a multiplier before multiplying the winnings. Also in this bonus, each Scatter that appears on the grid grants you 2 additional free spins. Wolf Pack Spins can be purchased for 350 times the original bet with a maximum bet of €25 per game round.
