hi Stephen!
Currently the game is 2-player only (My experience programming AI is very limited). To see Player 2’s board/pieces you need to use the crank.
As for how to play, I’d like to add in-game instructions in the future, but for now any Knucklebones guides should apply, such as this one: https://www.thegamer.com/cult-of-the-lamb-knucklebones-guide-dice-minigame-strategy-ratau-shrumy-klunko-bop-flinky/#:~:text=Players%20take%20turns%20rolling%20a,with%20the%20highest%20score%20wins.
