  • Patent number: 8313370
    Abstract: Video game systems and methods provide one or more software-based skill adjustment mechanisms for video game systems to adjust a difficulty level of the video games based on an existing skill level or game play of a player. The difficulty level of the video games is adjustable to correspond to an existing skill level of the player for removing digital blocks from a digital matrix, clearing digital complete horizontal lines from the digital matrix and/or avoiding game ending conditions. The difficulty level of the video game may be adjusted to facilitate skill-building game play for the player. The difficulty level of the video games is adjustable during game play that is approaching or leading to a game ending condition via software for one or more primary and/or secondary skill adjustment mechanisms.

  • Patent number: 6102796
    Abstract: Composing an image with fragments. The fragments of an image are downloaded from a server. The fragments are displayed in an initial configuration within the image. One of the fragments located at one of the positions within the image is then selected. The selected fragment is then moved to a second position within the image which has defined characteristics. The selected fragment is then visually altered to conform to the defined characteristics of the second position. The visual alteration may include altering the size or the aspect ratio or both of the fragments to conform to the defined characteristics of the respective positions, such as a positions within a grid, or altering the size or orientation or both of the fragments to conform to the defined characteristics of their respective positions, such as C-shaped fragments arranged radially around a center of the image. After the appearance of the selected fragment is altered, a new configuration of the image fragments may be displayed.

  • Patent number: 5944605
    Abstract: Composing an image from fragments of the image. The fragments of the image and a playing grid (used to define the fragments) are downloaded from a server. The positions of the fragments are shuffled within the grid. The appearance of each fragment is altered to conform to characteristics of the fragment's position or cell within the grid. After displaying an initial configuration of the fragments, one or more fragments are selected and moved to new positions or cells within the grid. In one embodiment, a single fragment is selected and moved to a new cell. In another embodiment, a fragment in one cell is selected. A new cell having another fragment is also selected. The two fragments are swapped between their respective positions or cells. After moving or swapping any fragments, the appearance of a moved or swapped fragment is altered to conform to characteristics (such as the size, shape, and aspect ratio) of the fragment's new position or cell within the grid.
