Nolimit City

A U-boat crew, with xNudge, xWays and xBomb all running so a single spin can compound in three directions.
Occult gothic rather than another tomb, and you decide whether the grid stands three, four or five rows tall.
xRIP abolishes the near miss. Win less than your stake and you are paid nothing at all, on a hit rate under 10%.
The cleanest demonstration of the nudging wild anyone has built, on an awkward 3-4-4-4-3 grid paying 576 ways.
Enhancer Cells sit above and below every reel, and a Jumping Wild doubles its multiplier each time it meets a Razor Split.
A psychiatric hospital theme that will put some people off before the maths ever gets a chance to.
Dwarves detonating a mine shaft, with a grid that grows underneath you every time an xBomb clears a space.
