From another thread:
lthough I must confess that I was more taken with the dice set cited on the 'Geek, called the Sicherman dice.
These have faces
1 3 4 5 6 8
1 2 2 3 3 4
which produces exactly the same set of results as two regular six-sided dice, but in an entirely different way, and a very different probability of rolling doubles. How cool is that?!
That is indeed VERY cool. I love how the probability of rolling any sum is maintained... though the dice numbers look so unnatural that I had to deconstruct the rolls and make a table to convince myself that it was true! Only a 1-in-9 chance of rolling doubles, instead of the typical 1-in-6....
I will keep these in mind for future designs... they could give an interesting twist to many situations.
