Quite strange to read all these...I too have played MG games since I've played online and even though my foray into them are rare these days, I still do play them, albeit at just one casino now.
Ladies Nite, for example, was one game I used to play all the time, hitting lots of features but it does seem to have changed. So much so that I won't play it any more, simply because the features seem so few and far between. In fact, blacklabrodor's post mentions 5 MG games I have little or no luck on regarding frequency of bonus rounds, strange isn't it?
Without any doubt, for me, 'Twister' has been the best paying and most frequent bonus round hitting over many years now. I've had some unbelievable streaks on that slot, and Katmandu has been another great slot for me. yesterday I was down to £1.89 so thought I'd try 25 spins on Katmando (@9p per spin), even though I'd had a great win/s on that slot during my previous session a couple of weeks ago. Anyway, cutting a long story short, I got up to £40, tried Twister again, won there, hit on a few other slots and in the end I cashed out £1,100
I find it strange how some people will mention 5 different MG slots as their best paying one's as well as being the most frequent hitting bonus rounds, yet the next person (me) has never had much luck at all at the same five slots - and this over a ten year period!
