Abstract
A system of linked gaming machines has each of the linked gaming machines connected to a common controller. In a normal mode of play, each of the linked gaming machines operates like a conventional machine where the generation of certain combinations of symbols provide awards to the individual players whose machines generate such combinations. In addition to this normal mode of play, a bonus feature is added where the generation of combinations of bonus symbols is used by a central controller to build up a pooled bonus value based upon the values of the combinations of bonus symbols generated by all the linked gaming machines. When a player hits a combination which causes the accumulated bonus value to meet or exceed a predetermined value, a bonus award is given to the player which caused the threshold to be exceeded.
