ABSTRACT:
An amusement apparatus having a plurality of symbol displaying elements, such as rotatable reels, with some of said symbols on the display elements being "Win" symbols having potential score values and others being "Hold" symbols without score values and said display elements adapted to randomly index in a viewing area during a play cycle a combination of said symbols with or without other symbols or "Blanks" having no value, and control elements associated with the changeable symbol display elements which are adapted to modify the random indexing of the symbols by holding automatically in indexed position in the viewing area any "Win" symbols during the play cycle immediately following a play cycle in which the "Win" symbol and a "Hold" symbol have been simultaneously indexed in the viewing area of the apparatus so that a winning combination of symbols may be automatically built-up in a series of play cycles before all of the symbol display elements are again changed and randomly indexed.
