Is it possible to change the game settings when playing against a computer? I started in Challenge mode, had a really good game, but then made a mistake. Can I allow takebacks at this point in the game? Or is this game just lost forever?
Note: I don’t mind losing stars on the game.
No, that's not an option. You could take the position before the move and play a new custom game.
