Abstract: Gaming machines with that may provide non-orthogonally arranged patterns of reels are disclosed. Such reel arrangements may exhibit highest-order N-fold radial symmetry where N=3 or N?5, and may feature groups of radially arrayed paylines. Due to the radial symmetry exhibited by such reel layouts or arrangements, a large number of paylines may be provided—far more than may feasibly be implemented on traditional, quadrilateral-format slot machines. Some implementations of such gaming machines discussed herein may feature additional features, such as the ability to rotate, flip, or otherwise transform reel stops to enable award enhancements or other rewards and/or complete winning patterns along paylines of the gaming machines.

Abstract: A gaming system, game controller and method of gaming implementing a game wherein one or more symbols are selected to be retained from a previous game outcome based on symbols which contribute to a winning symbol combination in the game outcome. One or more subsequent game outcomes can be generated including the retained symbols. The retained symbols from a previous game outcome can be selected from symbols which contribute to a winning symbols combination in the previous game outcome. In the subsequent game outcome, the retained symbols can contribute to further winning symbol combinations.

Abstract: This invention relates to temperature differential sensing means particularly suitable for sensing temperatures at respective opposite sides of a heat shield whereby alignment of the shield with respect to a heat source may be monitored so as to enable the shield to be maintained in operative aligned relationship with the heat source.

Abstract: Metal algicides, such as zinc and copper, are sprayed in the form of droplets of molten metal onto the surface of roofing granules or onto the surface of asphalt roofing compositions in which said granules are embedded. The metal algicides solidify and adhere on the surface of said granules or compositions as relatively fine, randomly distributed, irregular shaped metal globules. During periods of rain or dew upon atmospheric exposure of roofing compositions thus flame treated, or incorporating therein roofing granules so treated, the oxidized globules become ionized so that metallic algicidal ions are slowly released therefrom and leached over the roofing surface, thus retarding the biological growth of algae and/or fungi over extended periods of time.
