Theme & Atmosphere: Deep Sea Tension 🌑
Nolimit City absolutely nails the atmosphere. The visuals plunge you into the depths of the Atlantic — dim, steel-grey waters, the outline of your submarine, and mines drifting ominously past the viewport. It’s moody, immersive, and surprisingly cinematic for an online slot.
The soundtrack layers in subtle tension — low rumbles, the creak of the hull, and the distant ping of sonar. The character symbols depict the submarine crew, each more battle-worn than in the first game. All except the captain — he remains as unshakable as ever. Classic captain energy. 😎
If you love slots that build tension rather than just flash lights and jingles, Das xBoot 2 is right up your alley.
Key Features & Mechanics: A Fully Loaded Arsenal ⚙️
Das xBoot 2 is absolutely packed with features — Nolimit City pulled the best mechanics from the original and bolted on a whole bunch of new ones. Here’s your field guide:
xNudge Wild — This is a 4-row tall wild symbol that always nudges to become fully visible on the reels. Every nudge increases a wild multiplier by 1. In the base game, it lands exclusively on reels 3 and 4. When multiple xNudge Wilds appear, their multipliers are added together before your win is calculated. It’s one of those features that makes your heart rate spike every time you see it start to nudge down. 💥
xWays — Landing on reels 2 and 5, xWays symbols reveal a random regular symbol and can be 2 to 3 symbols in size. If more than one xWays symbol appears on a spin, they all reveal the same symbol — which can lead to some seriously stacked wins across the board.
xBomb Wild — These act as wilds that substitute for everything except bonus scatters, but here’s the clever bit: after wins are calculated, xBombs explode and destroy all non-winning symbol types (except wilds and scatters). The grid then refills, and each xBomb increases a win multiplier by one before the collapse. Even better, the xBomb multiplier carries over into free spins features. Talk about a chain reaction. 🧨
Periscope Up! — This is one of the standout features. Reel 3 can expand up to 8 positions high, and a special Periscope Wild may land there. When it does, a torpedo targeting sequence kicks in — a target appears, a torpedo fires, and if it hits, the Periscope Wild expands and nudges down, adding a multiplier with each nudge. A miss? It stays as a single wild. In the base game, Periscope Up! triggers randomly, but during certain free spins rounds it’s always active. This is one of those “edge of your seat” moments every time it pops up.
Torpedo Builder — When a full 2-symbol-wide boat appears in the Ocular window above reels 5-6, the Torpedo Builder activates. A torpedo tube appears beneath reels 2-5, and you get 3 spins to collect all 4 torpedo parts. Reels 2 and 5 drop xWays symbols, while reels 3 and 4 drop xWays Wilds. Build the full torpedo, and it launches to reveal a cascade of xWays across the reels. The anticipation of watching those parts slot into place over 3 spins is genuinely gripping. 🔧
Golden Torpedo Builder — The premium version. When a golden boat appears in the Ocular, the same torpedo-building sequence triggers, but the parts carry values of either +8 or +88. This is where the truly monstrous wins live — and yes, this feature can deliver the game’s full 59,999x max win.
A big evolution from the original? Both the Periscope Up! and Torpedo Builder features are now available in the base game, not just during bonus rounds. This means the tension never lets up, no matter when you’re spinning. If you want to explore more games from this provider, check out all Nolimit City slot demos for a full catalogue.
Free Spins: Three Tiers of Underwater Warfare 🎖️
Das xBoot 2 offers three distinct free spins features, each more powerful than the last:
Silent Hunter Spins — Triggered by landing 3 scatter symbols. You receive 8 free spins with the Periscope Up! feature permanently active. The Periscope Wild nudge awards a persistent multiplier that starts at x1 after the first nudge and grows by +1 with every subsequent nudge. Each xBomb hit also adds +1 to a cumulative multiplier for the rest of the round. Extra scatters during the round award +2 additional spins.
Wolf Pack Spins — Land 4 scatters to unlock 9 Wolf Pack Spins. A Torpedo Tube sits beneath reels 2-5 for the entire round, preloaded with xWays and xWays Wilds. Every time a boat appears in the Ocular, the torpedo launches and an identical one reloads for further enhancement — creating a compounding effect where each launch gets progressively more powerful.
Battle of the Atlantic Spins — The big one. Hit 5 scatters in the base game to trigger 10 Battle of the Atlantic Spins, which combines the best of both worlds — the always-active Periscope Up! from Silent Hunter and the Torpedo Builder from Wolf Pack. This is where everything converges for maximum destruction and maximum win potential. ☠️
When any free spins round ends, you may also be offered an Extra Spin purchase that preserves all existing multipliers and torpedo progress. The cost depends on the current state, and it’s only available if the price doesn’t exceed your total win.

Gameplay Breakdown: Getting Started 🎮
New to the game? Here’s a quick step-by-step to get you spinning:
Step 1: Set your bet — Choose between €0.20 and €100 per spin. In demo mode you’re using virtual credits, so experiment freely.
Step 2: Check your boosters — Decide if you want a Nolimit Booster active. Options range from the Bonus Booster (1.5x bet) to the Golden Torpedo Booster (4,500x bet).
Step 3: Spin the reels — Watch the 2-3-4-4-3-2 grid come to life. Keep eyes on reel 3 for Periscope Up! and the Ocular above reels 5-6 for boats.
Step 4: Watch for cascades — xBomb Wilds explode non-winning symbols and refill the grid, each adding +1 to a win multiplier.
Step 5: Study the paytable — Card royals pay 0.6x–0.9x for a 6-of-a-kind, while premium crew symbols pay 1x–5x, with the captain being the most valuable.
Step 6: Chase the features — Three scatters trigger Silent Hunter Spins, four trigger Wolf Pack Spins, five trigger Battle of the Atlantic Spins. Demo mode also lets you buy directly into any round.
Pro tip: The xBomb multiplier carries over into free spins, so a strong base game sequence can supercharge your bonus round.
Betting Range & Volatility: Know What You’re Getting Into 📊
Let’s talk numbers, because this is a game where understanding the statistical profile genuinely matters:
| Stat | Value |
|---|
| Min Bet | €0.20 |
| Max Bet | €100 |
| Volatility | Extreme (10/10) |
| RTP | 95.94% (highest config) |
| Max Win | 59,999x bet |
| Free Spins Frequency | 1 in 273 spins |
| Max Win Probability | 1 in ~25.3 million spins |
The RTP of 95.94% at the highest configuration is slightly below the typical Nolimit City standard, and there are two lower settings (94.02% and 92.03%) that online casinos with Nolimit City games may use — always check which version your chosen casino runs.
With volatility at the maximum 10/10, this is a game for players who can handle dry spells in exchange for massive payout potential. The 59,999x max win is extraordinary, though at 1 in 25.3 million odds, it’s firmly in “lightning strike” territory.
