Pedro Martínez: the link goes to your post, so i guess you are apointed the task to update the Hall of Fame (although Skittles can edit the post as well ;))
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 :))
in the netherlands this game is known as 'mens erger je niet'
which translates to 'man, dont be upset'
this translates to the same name as the czech one it seems.
we use different dice rules though. when you roll a 6 you can move a piece in, or move another piece already on the board for 6 steps, you then roll the die again, the new roll can be used with any piece you like, etc. when you cant use the die then your turn is over. but you dont have to move any pieces back.
i guess we use the czech name, but the english rules ... maybe because we are located in between geographically ? ;)
i like it when any rules though .... just know which rules are used where and you can have fun :)
(my gf and i play rummicub with different rules as well, before we start we agree which rules we use that particular time :))
