playBunny: Thank you for your response. I accept that people will develop many variations of a game, but I assume that somewhere there are basic rules of the game. As I look at the game preseted on this site it seems to be 95% chance with very little tactical skill facilitated. Of all the variations you mention, the 2 which would allow most tactical expression are the individual use of the dice rolls and the ability to stack and block. Maybe a variation of the present game could be added at some stage?
