“Dive, dive, dive! The crew has been submerged for over four years. Clearing sea mines, dodging enemy patrols and picking off destroyers is all in a day’s work for the sub crew. The submarine has gotten a few upgrades since its last deployment. It’s become stealthier and deadlier than ever before. The mission never changes… hunt prey and don’t get spotted!”

Theme, Gameplay & Payouts
Das xBoot 2 features a video slot design from Nolimit City with 6 reels arranged in a 2-3-4-4-3-2 layout, which can expand to 2-4-8-5-4-2. Each spin starts with a baseline of 576 ways to win, which can increase through features like Periscope Up! and xWays. The stake range allows bets from a minimum of 0.20 up to a maximum of 100. The game operates with a default RTP of 95.94%, slightly below the industry average, so players should be mindful of possible lower returns over time. Alternative variants with RTPs of 94.02% and 92.03% have been released, requiring players to verify the version before playing. Volatility is rated as high (extreme), making wins less frequent but potentially rewarding as the maximum win per spin is 59,999x the bet. Free spins occur roughly 1 in 273 spins, with wins exceeding 100x the bet happening at a rate of 1 in 734 spins.
Players will navigate another robust vessel equipped with various features surrounding the gameplay area. The submarine continuously moves through the deep, avoiding naval mines while searching for targets visible in the periscope. An intense atmosphere is built through foreboding music and the sounds of bubbling water, preparing players for the challenges ahead. The low-value symbols feature playing card icons, while high-value symbols depicting crew members include a cook, radio operator, mechanic, navigator, and captain. The game can be accessed on numerous modern devices, including desktops, smartphones, and tablets.
Wins can be achieved by landing between 3 and 6 matching symbols on adjacent reels starting from the leftmost reel. The low-value symbols are represented by 10, J, Q, K, and A on metal plates, paying between 0.6x and 0.9x the bet for six in a combination. The high-paying symbols yield between 1x and 5x the bet for a six-of-a-kind win. Additional symbols include xNudge Wilds represented by a war medal with a red ribbon, xWays symbols depicted as a war medal with a blue ribbon, and xBomb symbols which are visualized as naval mines, while Bonus symbols are illustrated by sonar imagery.

What features are available in the slot Das xBoot 2?
The available features include xNudge Wild, xWays, xBomb, Periscope Up!, Torpedo Builder, Silent Hunter Spins, Wolf Pack Spins, Battle of the Atlantic Spins, Nolimit Booster, and Feature Buy.
xNudge Wild
xNudge Wild symbols consist of 4 stacked symbols that can appear only on reels 3 and 4 during regular spins and only on reel 4 during the Periscope Up! feature. When they appear, the symbols nudge to occupy the entire reel, increasing their multiplier by 1 for each step moved. If multiple xNudge Wilds are involved in a winning combination, their multipliers are aggregated before being applied to the total win.
xWays
xWays symbols appear exclusively on reels 2 and 5. Upon landing, all xWays symbols on the grid transform into the same paying symbol, revealing 2 or 3 instances for each position.
xBomb
xBomb functions as a regular Wild, substituting for other standard symbols, and explodes after wins are calculated. This explosion removes all symbols except for Bonus symbols and Wilds, adding new symbols to the grid to create additional wins. Each explosion also contributes to the global win multiplier, increasing it by 1.
Periscope Up!
This feature can activate randomly on any spin, raising reel 3 to 8 positions high. During this spin, a special Periscope Wild may land, initiating a torpedo launch. If the torpedo hits a target, the Wild extends to the top of the reel and nudges down to cover it entirely, increasing the multiplier by 1 for each step taken. Should the torpedo miss, it functions as a standard single Wild.
Torpedo Builder
A 2-symbol wide ocular positioned above reels 5 and 6 activates the Torpedo Builder feature whenever a full boat appears. This feature initiates a 3-respin mode, using only reels 2 through 5 with a horizontal Torpedo area beneath. During these spins, only xWays and xWays Wild symbols can land, dropping to their designated positions in the Torpedo area. These symbols can hold values of +1, +2, or +3. When all spins are completed and all four positions are filled, they turn into xWays symbols and Wilds based on the collected instances during the feature.
If a golden boat is spotted in the ocular, the Golden Torpedo Builder feature triggers, charging active symbols with values of only +8 or +88.
Silent Hunter Spins
Landing 3 Bonus symbols anywhere on the grid activates 8 Silent Hunter Spins. Throughout this mode, the Periscope Up! feature is consistently active, and any multiplier increases from it and xBomb persist during the entire round.
Wolf Pack Spins
Triggering 4 Bonus symbols simultaneously in the base game awards 9 Wolf Pack Spins. Initially, the Torpedo area below the grid activates, preloaded with all four missile components, each valued at 2. Players can increase these values by landing corresponding symbols on the respective reels, similar to the Torpedo Builder feature. Whenever the ship appears in the ocular, the launch transforms the Torpedo area positions into xWays and Wilds with their assigned instance values. All values accumulate persistently during the game, along with the multipliers gained from the xBomb explosions.
Battle of the Atlantic Spins
Obtaining 5 Bonus symbols in the same base game spins rewards players with 10 Battle of the Atlantic Spins. This mode combines features from the previous bonus games along with a persistent multiplier from xBombs. Additionally, each Bonus symbol within the bonuses gives 2 extra spins.
At the end of any bonus, players may have the option to utilize the Extra Spin function, allowing them to purchase an additional round based on conditions achieved in the last free spin. This option will only appear if the cost of additional spins is less than or equal to the total wins attained from the bonus.
Nolimit Booster
Players can enhance their base game spins using options available within the Nolimit Booster menu.
1.5x = Bonus Booster, guaranteeing one Bonus symbol on every spin.
8x = triggers the Periscope Up! feature.
20x = initiates the Torpedo Builder feature.
4,500x = activates the Golden Torpedo Builder feature.
Feature Buy
Players can bypass the grind of the base game and trigger any of the bonus rounds instantly.
80x = awards 8 Silent Hunter Spins.
250x = grants 9 Wolf Pack Spins.
750x = rewards 10 Battle of the Atlantic Spins.
290x = Lucky Draw with a 50% chance for Silent Hunter Spins and 25% each for the other two modes.
Final Thoughts on Das xBoot 2
The original Das xBoot was a standout release, marking another bold claim from Nolimit City that they can create immersive experiences around any theme packed with innovative mechanics. The incorporation of the game’s features into the submarine theme was exceptionally well-executed, making them integral to the gameplay rather than just random pop-ups. The expanding reel resembling a rising periscope and the assembly of torpedoes enriched the overall experience. It appears that the developers adhered to the motto, ‘if it ain’t broke, don’t fix it’, as much of the same intensity is present in Das xBoot 2. While the imagery is largely recycled, the intense atmosphere reflects the realities of naval warfare, filled with determination and often desperation. The crew displays signs of wear as they cling to their sanity beneath the surface.
The gameplay has shifted significant action forms from the bonus rounds to the base game. Key features that were previously limited to free spins are now available during regular spins, allowing for exciting winning possibilities outside of mere Bonus symbols. While the original game had xNudge Wilds, xBombs, and xWays symbols to enhance engagement, the addition of Periscope Up! and Torpedo Builder during any standard spin introduces even more chances for unexpected victories. The ultimate highlight is the Battle of the Atlantic Spins, which amalgamate all features into a dynamic bonus round, offering players a glimpse at that coveted 59,999x maximum win. In summary, Das xBoot 2 successfully advances nearly every aspect of its predecessor while maintaining the unforgettable atmosphere that captured players in the first installment.
Das xBoot 2 returns with a formidable array of features, delivering yet another chapter of intense naval warfare filled with relentless action.
