Most sources say two dice, my Hungarian source says three. One says that the dice sports were a rule created to keep that initial 9 roll from being an automatic win. I've found one source which says that landing on the bridge simply meant you paid a toll, nothing more. Others say that's a shortcut to space 12. One source places a wine glass and forfeit on space 61, but I've not seen that anywhere else.
Sources vary on whether token-forfeiting was a standard part of the game or an option.
Some sources say that landing on the well is the same as jail and you get stuck until someone else comes along to get stuck. Others simply count it as a lost turn or two. The authors of the book in which it's printed weren't concerned with rules reproduction as much as noting game types in the social order. What I'm really looking for is a late 15th century Really Close To Definitive set of rules, or at least a playability consensus for the game.
