Hello everyone!
I am a fan of backgammon and have been using GNU Backgammon for a long time. There are currently two games implemented there: Backgammon and Hypergammon.
Is it possible to create on its basis, a similar game, but with a different set of rules?
What is needed for this? Where to begin?
You can read about the rules of the game here
