We present a method to instantiate game descriptions used in General Game Playing with the tabling engine of a Prolog interpreter. Instantiation is a crucial step for speeding up the interpretation of the game descriptions and increasing the playing strength of general game players. Our method allows us to ground almost all of the game descriptions present on the GGP servers in a time that is compatible with the common time settings of the GGP competition. It instantiates descriptions more rapidly than previous published methods.
