I like the new "Moon Princess Trinity" slot, because it is a nice 5x5 cluster grid and the 3 Girls have different power modifiers that can quickly push you into a Free Spin feature, where they blow on all girl cylinders. 

I played it for about 3 hours and it paid very well, but then it went quite.... and Love, Star, and Storm did not want to put out.    The game’s volatility was in the lower to medium range, which is still pretty hard.
