Apparently casinos retire dice after about 8 hours of use. Useful for discussing independent events - suppose that just before retirement these dice won a million for someone...does that make them "lucky"? If so I doubt paramount would sell them on so cheaply......

These Sicherman dice are a recent discovery I made at grand-illusions.com. They have some interesting properties. They also sell the non-transitive dice that feature in my dice world cup simulation.

This is a 100 sided dice from rpgshop.com which I have now bought and it works very well. It has a weight in the bottom to stop the dice effectively on any number from 1 to 100.

Here are some images of a nice die that I bought at Village Games, Camden Lock, London. Each side is a different shape. A student of mine is using it in her math studies project, investigating its probability distribution. You can buy them here.

      Call me self-indulgent but I had to include a recommended car.  I could write all the reasons why I bought her - but space for a pram isn't one of them. So meet Betty, my 1999 TDI New Beetle. Here she is with a rare dusting of snow a couple of winters ago.      
     

Disco dice! Bought from maxi toys in Toulouse. Made of rubber and with replaceable batteries. Perfect for those late night dice games.

     
      After much pestering, Betty persuaded me to buy these fuzzy dice for her. They have side 2 inches and I bought them here.
