I think it’s really simple.
It’s basically Backgammon with animal tokens.............
May as well say it’s just like Chinese checkers. The three boards are nothing alike.
Also, backgammon is similarly ancient, but the way(s) to play has had continuity to modern times.
Senet is another game popular in ancient Egypt, and similarly the rules were lost.
