Satanic Gamble

I came up with this one, believe it or not through bluetak. I was sitting in English class, bored out of my brain so I got out some bluetak and started fiddling around with it. First of all I made a perfect cube; then I put some numbers on it so my mate and I could ignore our teacher and play gambling games.
After we got bored of that my friend took the cube and started playing around with it himself. All he did was make the courners pointy and suddenly I was hit with inspiration. For some reason the die now looked a little evil and from there sprung my idea.
