Das xBoot (NoLimit City) – Review & Demo Play

Das xBoot - Now or Never!

Das xBoot throws you into a murky U-boat scene with a 6-reel 2-3-4-4-3-2 set-up that shifts with features. It starts on 576 ways and can swell to 75,712. Bets run from 20 p/c to €100 per spin. The vibe is tense, comic-book visuals with a score that hums under the action. It is rated as highly volatile, so momentum comes in bursts. I felt the pressure rise when multipliers stack and the grid expands, which fits the theme.

Das xBoot - Theme & Settings

The setting nods to classic submarine warfare with a periscope flavour that shows in the mechanics. The asymmetric grid is key, as reels grow in bonus play and ways spike when the special symbols line up. I rate the presentation for how it matches the features, especially when explosions clear the screen and the sound swells.

Pays split into 10-A lows and five crew premiums. You get chefs, radio guys, engineers, periscope operators, and the Kapitanleutnant. The top cap pays 20x the stake for six of a kind. Special symbols include the xNudge Wild, xWays, xBomb, and a sonar scatter on reels 2-5. These are the core pieces that drive the big swings.

Das xBoot - Bonus Features

xNudge Wilds land on reels 3 and 4 as 4-high wilds. They always nudge to full height and add +1 to their wild multiplier per nudge. If more than one is part of a win, multipliers add together and then apply. This can turn a modest line into a proper hit, especially when ways have expanded.

xWays appear on reels 2 or 5 and reveal 2-3 instances of a random regular symbol. If several xWays land, they all reveal the same pick. xBomb Wilds increase the global win multiplier by +1, then explode to remove non-winning symbols and drop as wilds. If free spins trigger, that global multiplier carries over. Scatters show on reels 2-5.

Das xBoot - Free Spins Features

Three scatters award 8 Silent Hunter Free Spins. Reel 3 extends to 8 positions and can hold a Periscope Wild. If reels 1 and 2 match with a Periscope Wild on reel 3, a torpedo launch sequence fires. Sink the target and the Periscope Wild covers reel 3, nudging to add to its multiplier while also adding to any global value. Any scatter adds +2 spins.

Four scatters trigger 8 Wolf Pack Free Spins. A torpedo tube appears under reels 2-5. Torpedo Wilds drop xWays tiles into the tube, starting at x2 and climbing by +1 per new Torpedo Wild up to x9. Fill all four positions to launch the torpedo. Reels 2 and 5 become xWays symbols, while reels 3 and 4 turn into xWays wilds. Each launch adds +1 to the win multiplier. Scatters add +2 spins.

There is a Nolimit Bonus buy. Silent Hunter costs 75x the bet with RTP around 96.57%. Wolf Pack costs 350x the bet with RTP around 96.58%. I use buys when I want the periscope or torpedo pressure without waiting on scatters.

Das xBoot - RTP, Volatility, and Payouts

RTP is variable, so I look for the 96.03% setting; a lower 94.02% version exists. Variance is fierce, rated 10 out of 10. Wins hit at about 22.07%, and free spins land on average every 211 spins. The max win is 55,200x the bet, which triggers a shut-down feature if you land it. Ways can reach 75,712 under full build.

The base starts on 576 ways and the bet spread is 20 p/c to €100 per spin. The global win multiplier from xBombs can roll into free spins, which matters a lot when the periscope or torpedo sequence lines up. I treat the base as set-up, but it can jump when multipliers and xWays sync.

Das xBoot - Slot Verdict

This one plays all or nothing, which suits a sub hunt theme. Silent Hunter often gives a couple of Periscope Wild moments per round, and when an xWays or xNudge joins, the grid can go off. Wolf Pack is where I have seen the biggest spikes by building the torpedo to x9 and launching into stacked wilds. Expect tease after tease and the odd dry run on reel 1. One spin can still turn the whole session.
