Unfortunately, "Bulka" is not a well-known board game for which standardized rules or a generally recognized game description exist. It may be a less known or regionally varying game, or it could be a typo or a misinterpretation of another game.
If you have information about a specific game, I'd be happy to learn more about it and analyze it in detail! Alternatively, you could check the name of the game or mention other known names under which it might be known.
