The idea of playing it with one line is that, as the bonus is winspins, you’re guaranteed a line of something which pays well as you’re only playing on that one line rather than spreading your bet across ten. The flaw of this is, the bonus will still pay the same on average whether you’re playing one line or not. Playing one line on any game is basically just a hyper volatile way of playing – less frequent wins but higher paying wins when you manage to land them. It’s just down to personal preference.
I personally have had a terrible experience playing Pimped one line in the past. I think I have 40% RTP (maybe even lower) over 3,000+ spins. One line of premiums and I’m back in the game, but yeah, just found it incredibly boring and balance draining in my own experience!
Best of luck 🙂
