Spika was the major boardgame publisher in DDR (Deutsche Demokratische Republik, in the west also known as GDR - German Democratic Republic, or more casually as East Germany). Spika games typically used simple roll-and-move mechanics or were variations of traditional boardgames, such as Pachisi, Halma, etc.
The full name of the publisher was VEB Spielewerk Karl-Marx-Stadt and indeed 'Spika' is an acronym of the latter part. It roughly means 'Karl-Marx-Stadt Game Works' while 'VEB' stands for 'Volkseigener Betrieb' or 'People-owned enterprise'. (The city of Chemnitz was known as Karl-Marx-Stadt between 1953-90.)
The brand disappeared after German reunification in 1990; presumably, the company was merged or otherwise liquidated. Today, Spika games are Ostalgia collector's items.
