In Response To: SHG dice (rew)

Neil Robins brought the original SHG problem to light. Will Womack then confirmed it with a sample that was larger, and I confirmed SHG had a problem by analysing my sample of 600,000 rolls. This was resolved by October 2009 with my assistance. Will Womack did a lot of work to keep people informed and collect dice for the studies I eventually did. His blog of what occurred is still available here: http://backgammoncamp.wordpress.com/2009/10/11/safe-harbor-games-dice/

SHG still uses the dice in question in the social rooms ("Red dice" Rooms). These dice generally a probability of a double being thrown at about 9.2%-9.6% (rather than 1 in 6).The chance of rolling an individual 1,2,3,4,5,6 roll is about what you'd expect. The dice in these "Red dice" rooms don't favor anyone in particular. I would deem them fair but not representative of typical dice.

The proper dice are in the "Yellow Dice" rooms.
