Two men dicing with two kinds of 7-sided dice F84V
There are other seven-sided dice than the ones We describe above. And
this is how they are: they have two flat ends, the upper end with seven
and the lower with six. The sides have five faces and because the sides
are odd in number they cannot help but fall edge up. And for these five
sides the play is the same as We described before. And this is what they
look like.
