Design and Graphics
The visual design of Das xBoot 2 centers on a gritty, immersive submarine interior submerged in ocean depths, with the 6-reel grid integrated into the vessel’s machinery. The background depicts constant motion through underwater environments, evading naval mines and scanning for targets via periscope views. Symbols are thematically cohesive: low-paying icons (10, J, Q, K, A) appear on weathered steel sheets, while high-paying crew members—including the cook, radio operator, mechanic, navigator, and captain—display chaotic, determined expressions reflecting the high-stakes tension of U-Boat operations. Special symbols feature a red-ribbon war medal for xNudge Wilds, a blue-ribbon medal for xWays, a naval mine for xBombs, and a sonar image for Bonus symbols.
Gameplay Mechanics
Das xBoot 2 employs a 6-reel setup with initial rows of 2-3-4-4-3-2, providing 576 ways to win. Wins form when 3 to 6 matching symbols land on adjacent reels starting from the leftmost reel. The grid can expand to 2-4-8-5-4-2 via features like Periscope Up! and xWays, increasing win potential. Base game flow begins with standard spins, where random activations of Periscope Up! and Torpedo Builder inject volatility. An ocular above reels 5 and 6 monitors for “boat” symbols to trigger Torpedo Builder, while Periscope Up! randomly tallies reel 3.
Special symbols drive mechanics:
- xNudge Wild (red-ribbon medal): 4-stacked on reels 3-4 (base) or reel 4 (Periscope); nudges to fill the reel, multiplier +1 per step; multiples add multipliers.
- xWays (blue-ribbon medal): Lands on reels 2 and 5; all transform to one paying symbol, each revealing 2-3 instances.
- xBomb (naval mine): Wild substitute; explodes post-win, clears non-Bonus/Wild symbols, refills grid, global win multiplier +1 per blast.
- Bonus (sonar): Triggers free spins on 3+ (3=Silent Hunter, 4=Wolf Pack, 5=Battle of Atlantic).
The paytable divides into lows (0.6x-0.9x for 6) and highs (1x-5x for 6 captain). Features like persistent multipliers in bonuses and chain reactions from xBombs create cascading excitement, with the submarine theme weaving seamlessly into grid expansions and torpedo assemblies for intuitive, thematic gameplay.
| Symbol Group | Pay for 6-of-a-Kind |
|---|---|
| 10, J, Q, K, A (Lows) | 0.6x to 0.9x bet |
| Crew: Cook to Captain (Highs) | 1x to 5x bet |
Bonus Features
Das xBoot 2 packs base game and bonus features for relentless action. Periscope Up! triggers randomly, expanding reel 3 to 8 rows; a Periscope Wild may launch a torpedo—if hit, it expands and nudges down with +1 multiplier per step; miss yields a single Wild. Torpedo Builder activates on full “boat” in the reels 5-6 ocular: 3 respins on reels 2-5 with a Torpedo area below; only xWays/xWays Wilds land (+1/+2/+3 values), filling all 4 spots to deploy as multi-instance symbols/Wilds. Golden boat variant yields +8/+88 values.

| Silent Hunter Spins | 3 Bonus | 8 | Always-active Periscope Up!; persistent xBomb/Periscope multipliers |
| Wolf Pack Spins | 4 Bonus | 9 | Pre-loaded Torpedo (all 2s); persistent values/launches; xBomb multipliers |
| Battle of the Atlantic Spins | 5 Bonus | 10 | Periscope + Torpedo active; persistent multipliers from all |
