finally tried one of those megaways slots.

finally tried one of those megaways slots last night after seeing people talk them up for ages. the changing reels caught my eye, but on a few spins they kept shifting and i was still trying to work out what had landed by the time it stopped. i can see why people like having all those ways to hit, but it was harder to follow than i expected and the spins seemed to take a while. maybe i just need to get used to it... is there a feature people look for to decide if a megaways game is worth sticking with, or do you just play a bit and see if it clicks?
