Hi. I hope this is in the right place.

I bought a joker clock
see: http://www.prudhoemagic.co.uk/advanced_s......t=Search
And probably I am missing something or maybe I am just stupid :o) but even with the explanation I do not get it at all....

What I do (as I understand I should do from the explanation):
1). I set the time on a number
2). I roll the clock on the site over the table
3). I wait till it fall. sally it falls with the lid-cover-site up
4). I turn it around (how??? with left hand, right hand, clockwise, anticlockwise, topoverbottom,bottomovertop???? Am I righy that at this point I do not know which site is up or down / left or right ??
5. I see the dot on the backsite but as I have no idea which site is up or down or left or right how can I ever tell if the dot is on let's say 12 or 6 or 3 or 9 o'clock?????

Iam almost sure I am missing something. I hope you can help me out!!
