Das xBoot 2wei! rejoins a submarine crew that has spent more than four years under water, clearing mines and sinking destroyers in an upgraded, quieter boat. Nolimit City’s sequel starts on a 2-3-4-4-3-2 grid with 576 ways, can grow to 2-4-8-5-4-2, and has a max win of 59,999x the bet.
Gameplay
xNudge Wilds are four high, land on reels 3 and 4 and add +1 to the multiplier with each nudge. xWays symbols land on reels 2 and 5 and reveal a random symbol two or three high. xBomb Wilds blow up non-winning symbols, add +1 to the win multiplier and let new symbols drop in. Periscope Up! grows reel 3 to 8 positions and adds a Periscope Wild that grows and nudges for extra multipliers when its torpedo hits. A full boat in the Binocular above reels 5 and 6 starts the Torpedo Builder, with 3 spins to build a torpedo that adds xWays symbols and Wilds on launch. Golden boats bring parts worth +8 or +88.
Bonus rounds
Three, four or five Bonus symbols award 8 Silent Hunter Spins, 9 Wolf Pack Spins or 10 Battle of the Atlantic Spins. Silent Hunter keeps Periscope Up! active, Wolf Pack adds a pre-loaded Torpedo Tube, and Battle of the Atlantic combines both. In every round, each xBomb adds +1 to a multiplier that lasts to the end, and extra Bonus symbols add 2 spins. An Extra Spin may be offered when a round ends. Boosters cost 1.5x, 8x, 20x and 4,500x the bet.
