Hi Brian,
At present, each player in a Bluetooth link must have identical Convention Cards as well as the same version number of BriJ. There are plans to lift this restriction in a later release. This is posted elsewhere in the forum.
Robot play doesn't currently use random choices for the card to play, though there is good reason to do so and the technique may appear in future (
after lifting the above restriction).
BriJ2 scores also depend on the Convention Card (because play is influenced by the bidding), so could differ if conventions aren't identical.
Perhaps you could email
bjsoftware42@gmail.com if you can add any detail to the "
Brij2 scores change to different values after a few seconds" issue, or any of the other points you've noted?
Thanks for your contribution.
