Abstract: A method of gaming comprising: selecting in each game round a plurality of symbols for display to a player in a set of display positions; superimposing a distorting element over one or more of the display positions so that one or more of the symbols can be modified, in response to determining that the distorting element should appear; and determining an outcome for each game round based on the selected symbols as modified by the distorting element.

Abstract: A method for use with a gaming machine including presenting an outcome by displaying a symbol as travelling along a path and stopping in a stopping position that overlies another game symbol.

Abstract: A method for use with a gaming machine including presenting an outcome by displaying a symbol as travelling along a path and stopping in a stopping position that overlies another game symbol. An award is paid or changed when there is a particular relationship between the symbol.

Abstract: A method of gaming comprising: selecting in at least one game round a plurality of symbols for display to a player in a set of display positions; modifying the displayed symbols copying each symbol in an original subset of the display positions to at least one clone subset of the display positions which is identical to or laterally displaced from the original subset, in response to determining that a subset of the symbols should be cloned; and determining an outcome based on the modified symbols.

Abstract: A method of gaming comprising: selecting a plurality of symbols for display at a plurality of display positions, the selecting being performed by selecting from a set of symbols including one or more modifiable symbols, each modifiable symbol adapted to receive a modifier; determining whether a corresponding modifier is a available for each selected modifiable symbol; modifying each selected modifiable symbol in respect of which a positive determination is made by adding the modifier to the modifiable symbol; and determining whether to make an award based on the plurality of symbols as modified.

Abstract: A method of gaming comprising: selecting a plurality of symbols and displaying the symbols at a plurality of display positions on a display; determining whether there is a match between a first subset of symbols at a first subset of the display positions and a second subset of symbols at a second subset of the display positions based on at least one matching rule, the first and second subsets of display positions having the same number of display positions; and taking at least one designated action if a match is determined.

Abstract: A gaming system, comprising a game controller arranged to control play of a game, and a display arranged to display a representation of play of the game, the game controller being arranged to select a plurality of symbols from a set of symbols for play of the game, to control the display to display a plurality of the selected symbols in rows and columns, to determine a game outcome based on patterns of symbols in the rows and columns, and also being arranged to generate a feature game in response to a trigger condition, and determine an outcome of the feature game depending on the occurrence of a non-linear pattern of symbols.

Abstract: A method of gaming comprising: generating a game outcome by selecting symbols for a plurality of symbol positions arranged in a plurality of columns, at least some of the selected symbols being displayed to a player; generating a win entitlement by selecting a symbol pattern to be evaluated in respect of the game outcome, the symbol pattern consisting of a subset of displayed symbol positions; and evaluating the win entitlement by determining the extent to which the subset of displayed symbol positions corresponds to one or more designated winning symbols.

Abstract: A gaming system, comprising a game controller arranged to control play of a game, and a display arranged to display representations of play of the game, the game controller being arranged to select a plurality of symbols from a set of symbols for play of the game, and control the display to display at least a plurality of the selected symbols in symbol positions in one or both of rows and columns, the game controller being arranged to select at least one additional symbol and to control the display to display the at least one additional symbol associated with a strip associated with one of the symbol positions.

Abstract: A method for use with a gaming machine including presenting an outcome by displaying a symbol as travelling along a path and stopping in a stopping position that overlies another game symbol.

Abstract: A method of gaming comprising: (a) displaying a plurality of first symbols; (b) displaying a plurality of second symbols; (c) matching at least one of the first symbols to at least one of the second symbols; (d) removing each first symbol which is matched with the second symbols; and (e) replacing each removed first symbol with an additional first symbol to thereby display a modified plurality of first symbols.

Abstract: A machine vision system and method of enhancing the imaging of an article which is comprised of optically translucent or semi-transparent material. Generally, the system includes a vision processor, a video camera, a computer, and an illuminator. The illuminator directs light, in a three dimensional space, at a surface of the material other than a surface to be imaged. The light which enters the translucent material is scattered isotropically within the material and emerges from the surface to be imaged, in effect illuminating the material. The illumination enhances contrast, that can be typically achieved with conventional lighting, between the material and its background or adjoining components permitting the machine vision system to clearly image and detect features of the article.

Abstract: A method and apparatus aligns device components based on an analysis of an image of features of the components to be aligned. The image is analyzed for deviation in component alignment, and a signal, based on the deviation, is sent to a positioning apparatus to adjust the position of the components relative to each other. The image of the components is advantageously a top view which permits measuring deviations in alignment of features on the top surfaces of components. The components are advantageously bonded together after alignment, and the alignment accuracy of the bonded components is checked.

Abstract: A method and apparatus measures a deviation in alignment between two components of a product wherein each component is characterized by a respective pattern and wherein each pattern comprises respective elements. The centroid of each element in each respective pattern is indicated, and based on the centroid indications, the center of each respective pattern is indicated. The deviation in alignment between the two components is determined as a function of the indicated position of the centers of the respective patterns, and positioning of the components is controlled as a function of the indicated position of the centers of the respective patterns.
