Languages with the Most Grammatical Cases

Nice quiz idea! Though ultimately it's difficult to give an absolute number of cases for a given language: often it's not a clear impartial concept, but will depend on how classification works in the traditional grammar o each language. For instance, there is an equivalent structure in Finnish and Estonian for the commitative ("with") case, but Estonian treats it as a separate case whereas Finnish trats it as a postposition. In Armenian, the traditional number of cases is higher than the effective number of distinct noun forms, etc.
