we also have different rules for a cards game called 'klaverjassen' (i think its called 'spades' in english)
i live in alkmaar, close to amsterdam, and studied in amsterdam where i played the game a lot
my gf studied in leiden, close to rotterdam, where she learned the game.
there are 2 sets of rules, the amsterdam type, and the rotterdam type, everyone in the netherlands knows which type they play, and most know both sets of rules
before we play a game we agree upon which rules we use
both types are still called klaverjassen though :)
(my gf also learned scrabble in a different way, she has a different boardgame called 'boardscript' which has a few different rules, but its still mainly scrabble, we play that game most of the time now.)
the scrabbles have different names and different rules
the klaverjassen types however have the same name, just different sets of rules which we agree upon (and we also did in college when played the game with people from either amsterdam or outside :))
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
