ABSTRACT:
In a gaming machine of the kind which selects a combination of symbols at random during each game and awards prizes when predetermined prize-winning combinations occur, a detector for detecting said prize-winning combinations of symbols comprising a first memory for storing information of each of a number of predetermined symbols which can occur in said selected combinations, a second memory storing information of each of a number of predetermined symbol occurence patterns which can occur in said selected combinations, a first set of comparators for comparing each of the symbols in a selected combination with each in turn of said predetermined symbols stored in said first memory so as to determine an occurrence pattern for each of said predetermined symbols, and a second set of comparators for comparing each determined occurrence pattern in turn with a number of predetermined occurrence patterns stored in said second memory which are associated with the predetermined symbol used for comparison in determining said occurrence pattern and which correspond to prize-winning combinations, the second set of comparators producing a coincidence signal to indicate a win when the determined occurrence pattern corresponds to a predetermined occurrence pattern. Thus each selected combination is analysed a plurality of times using a different combination of predetermined symbol and occurrence pattern each time so as to "look for" each possible prize-winning combination in turn.
