Das xBoot 2

Overview

Das xBoot 2 is an extreme-volatility video slot from Nolimit City with a tense World War II submarine theme, xNudge Wilds, xWays symbols, xBombs, Periscope Up!, Torpedo Builder, and three layered free spins modes. The game follows the original Das xBoot but expands the feature system with deeper torpedo mechanics and more ways for the grid to change during a round.

The slot starts on a 6-reel layout with a 2-3-4-4-3-2 symbol structure and 576 ways to win. This setup can change when special features activate. Reel 3 can grow during Periscope Up!, xWays can add more symbol positions, and Torpedo Builder can transform parts of the reel area into split symbols or split wilds.

RTP, Volatility and Max Win

Das xBoot 2 has a highest listed RTP of 95.94%. That is slightly lower than many standard Nolimit City releases, so players should check the live game information screen before playing for real money.

The game uses an Extreme volatility model. It offers a maximum payout of 59,999× the bet, with a listed max win probability of around 1 in 25.3 million. This puts Das xBoot 2 firmly in the high-risk category. It can create huge outcomes, but players should expect long dry spells and sharp bankroll swings.

xNudge, xWays, xBomb and Periscope Up

The core gameplay relies on several Nolimit City mechanics. xNudge Wilds can land on reels 3 and 4. They nudge until fully visible, increasing their multiplier by 1 with each nudge. During Periscope Up!, the xNudge Wild can only land on reel 4.

xWays symbols can land on reels 2 and 5. They reveal a random regular symbol and can appear in sizes of 2–3 symbols. If multiple xWays symbols land, they reveal the same symbol.

xBomb Wilds substitute for regular symbols, then explode symbols that do not form part of a winning combination. They also increase the win multiplier by 1 before the next collapse. This multiplier can carry into Torpedo Builder and the free spins modes.

Periscope Up! adds one of the game’s main thematic moments. Reel 3 grows to 8 positions, and a Periscope Wild can trigger a torpedo launch sequence. If the torpedo hits, the Periscope Wild expands upward and nudges down while adding multiplier value.

Torpedo Builder and Free Spins

Torpedo Builder can trigger in the base game and Silent Hunter Spins when a full boat lands in the binocular area above reels 5 and 6. The feature gives players 3 spins to build four torpedo parts. Reels 2 and 5 collect xWays values, while reels 3 and 4 collect xWays Wild values. If the torpedo completes, it launches and reveals the collected values on the grid.

Golden Torpedo Builder works in a similar way but uses much larger values of +8 or +88. This creates the most explosive feature setup in the game, but it also fits the game’s extreme-risk profile.

The free spins system has three tiers. Silent Hunter Spins trigger with 3 bonus symbols and award 8 spins. Wolf Pack Spins trigger with 4 bonus symbols and award 9 spins. Battle of the Atlantic Spins trigger with 5 bonus symbols and award 10 spins. The highest tier combines Periscope Up! and Torpedo Builder.
