One of the less-covered aspects of World War II was German submarine warfare. Countless subs silently stalked the Atlantic Ocean, sinking supply ships to prevent resupply. In Das xBoot 2wei (Zwei), Nolimit City takes us on another daring undersea raid. Do you have what it takes to survive and thrive beneath the waves, or will you end up as fish food?
We explore everything you need to know about the Das xBoot 2wei slot in this review. Keep reading to find out if it’s the right game for you.
Das xBoot 2wei Visuals
The art team has outdone itself in making this game. The reels are overlaid on the moving submarine, making it clear how cramped the crew would be. If that’s not stressful enough, you can see more than a few floating mines we’re just barely sneaking past. You might even spot a jellyfish or shark swim past, or bullets fired above the water sinking past your submarine and exploding.
Available symbols in this Nolimit City slot are a mix of playing card royals and crew members. Some look a bit more put together than others; personally, we wouldn’t want to try whatever the cook is preparing. Bonus icons include medal Wilds, medal xWays, xBomb Wilds, and radar Scatters.
Das xBoot 2wei Gameplay and Features
You play the Das xBoot 2wei slot on a six-reel grid with a 2-3-4-4-3-2 layout and 576 ways to win. To win, you need three or more matching symbols in adjacent positions, starting with the leftmost reel.

xNudge Wild
The xNudge Wild will always nudge up or down to be fully visible, covering the entire reel. Each nudge increases the Wild’s multiplier by one. This Wild can only appear on reels 3 and 4. If several multipliers are present, they’re added together first and then applied to the total win.
xWays
xWays symbols can only appear on reels 2 and 5. They pick a random symbol and turn into it, with each xWays icon containing two or three symbols. If two xWays icons land, they will both reveal the same symbol. Revealed icons must be regular, paying symbols.
xBomb Wilds
xBomb Wilds explode all symbol types that aren’t part of a winning combination except for Scatters and other Wilds. After the explosion, remaining symbols drop to the bottom while new icons fall from the top, filling the playing area. The multiplier will also increase by one. This multiplier is carried over to Torpedo Builder and all three free spins features.
Periscope Up!
The third reel expands, increasing its size to eight symbols. While expanded, a special Periscope Wild can land on this reel. If that happens, the captain orders a torpedo strike. If the torpedo hits its mark, the Periscope Wild expands to cover the entire reel and then nudges downwards. Each nudge increases the win multiplier. If the captain misses, the Wild does not expand.
Periscope Up! triggers randomly during normal gameplay and Wolf Pack free spins. However, it’s always active during the Silent Hunter and Battle of the Atlantic bonus rounds.
Torpedo Builder
During normal gameplay and Silent Hunter free spins, you can trigger the Torpedo Builder feature. It activates when the ocular above reels five and six locks onto a boat. This causes a torpedo tube to appear beneath reels two to five. Only torpedo parts can land on these reels while the first and sixth reels are closed.
You get three spins to assemble a torpedo. Reels two and five can land xWays symbols, while reels three and four will reveal xWays Wilds. These bonus icons become active when the torpedo fires, increasing your odds of success. However, the torpedo will only fire if all parts are filled.
If a golden boat appears in the ocular, you get an upgraded version of the Torpedo Builder feature with better bonus icons.
Free Spins
There are three types of free spins you can unlock based on how many Scatters appear on the reels.
- Three Scatters grant 8 Silent Hunter free spins
- Four Scatters award 9 Wolf Pack free spins
- Five Scatters unlock 10 Battle of the Atlantic free spins
Silent Hunter free spins have the Periscope Up! feature permanently active. The Periscope Wild also has a permanent multiplier, which grows by 1x for each nudge. Additionally, xBomb Wilds increase the multiplier by one each time they land.
During Wolf Pack free spins, the Torpedo Builder feature is permanently active. You start with an assembled torpedo and continue upgrading it with each spin. When a ship appears in the ocular, you fire the current torpedo while an identical copy takes its place.
Finally, Battle of the Atlantic free spins combine the bonus effects of the previous two bonus rounds, giving you the best odds of winning.
