Happy Hooves PowerNudge: Slot Overview If you value the company of four-legged animals, you may be interested in Happy Hooves PowerNudge, an online slot from busy developer Pragmatic Play. To date, this pg superslot is the third PowerNudge slot, and so far, each one has tweaked the mechanic to do slightly different things. Happy Hooves PowerNudge offers the most tweaked version so far, but don't get the idea that this is a majorly innovative game, as the PowerNudging abilities have been 'inspired' by another popular online slot. You'll see.
