Never played it, although we have a different version called Glasie Glasie back home. I grew up being told to never never ever play it.
Wouldn't have made much difference, though. One of my dad's sisters messed around with it before he was born. I think she was trying to contact her boyfriend who passed in a motorbike accident. Yeah, ever since then, apparently our family has been haunted. Ouma and dad were able to see these things. Me being next generation, have seen a handful of them throughout my life, but not as often as my dad. I can definitely sense them, but I'm kinda blind to them most of the time. My daughter seems to be able to see them as well.
So, nope. Nope nope nope. Don't mess with stuff you don't fully understand. Too many people have had to pay the price for one ignorant idiot's actions.
