I've been thinking about how backgammon might be extended to 3 or more players. Below is a mockup of my current idea of what the board might look like. The concept could technically be extended to any number of players, but it would be less and less fun with more players probably, because each player only encounters the checkers of the players on either side of him or her.
I'm excited to try this out with some friends but haven't been able to yet because of COVID-19. So for now I'm looking for feedback on problems that may make the game unworkable, or improvements to the board layout (the flow of the pieces is a little awkward but it's the best I've come up with so far).
