Investigation report: High volume betting clubs in the Mass Cash Winfall

This letter gives a fascinating look at the structure of three high-volume betting clubs that formed around the Massachusetts Cash Winfall game.

In the past, the Boston Globe has done its best to cast a pretty negative light on these bettors. This investigation gives quite a different view.

Starting on p. 14, the description of the August 16th, 2010 drawing and the MIT club's trigger of a surprise rolldown is both fascinating and a bit scary in terms of what it means about the structure of the lottery commission.
