Abstract: An electronic gaming machine includes a processor configured to control a display to display a matrix of award symbol display positions, at least some of the award symbol display positions including an award symbol. The processor is also configured to control the display to display at least one selection indicium within the matrix, determine a starting award symbol display position and an ending award symbol display position within the matrix, randomly determine a path between the starting award symbol display position and the ending award symbol display position, control the display to display the at least one selection indicium traversing the randomly determined path between the starting award symbol display position and the ending award symbol display position, and provide an award associated with the ending award symbol display position.

Abstract: Electronic gaming machines and systems are disclosed that provide for a symbol-based main game that features an array of symbol positions that may, if an array growth condition is met, increase in size. Determining whether the array growth condition is met may involve determining how many array growth symbols are shown in association with a game play. A further determination may be made as to whether a feature game trigger condition is met and, if so, a feature game may be presented that utilizes the same array of symbol positions that were present in the main game when the feature game was triggered. Additional array growth may occur in the feature game if the array growth condition is met again.

The tool includes a body having an attachment point for the cutting devices. Teeth are disposed along a length of a periphery of the body for cutting the solid and sanding layer disposed over an exposed outer surface of the body for sanding new surfaces in the solid material created upon cutting by the cutting devices.

Abstract: An electronic gaming device that includes a display device, an input device, a memory device, and a processor is described. The processor causes to be displayed a dual symbol configured as a wild symbol and as a credit on reel (or cash-on-reel) symbol that indicates a prize to be awarded if a trigger symbol also lands in the same row as the dual symbol. The processor causes a base game to be initiated that includes causing symbols to be displayed on reels within a display matrix on a display device wherein each reel is configured to spin. During game play of the base game, the dual symbol, if displayed, persists between different reel spins and moves up one row each reel spin from a previous symbol position to a new symbol position.

Abstract: A gaming system is provided. The gaming system may include a game display configured to display a game interface including a matrix having a plurality of rows including a plurality of matrix positions and a processor configured to determine a number of wild symbols currently displayed in the matrix, in response to determining the number of wild symbols currently displayed in the matrix exceeds a threshold number, determine a number of spin credits, in response to the number of spin credits being greater than zero, determine a weighting factor defining a probability for displaying a symbol in a respective matrix position, apply the determined weighting factors to respective lookup tables for each matrix position not currently displaying a wild symbol, and determine, for each matrix position not currently displaying a wild symbol, a symbol to display.

Abstract: Among the various aspects of the present disclosure is the provision of treatments, monitoring treatment or progression, or methods for detecting utDNA in a subject having or suspected of having a urinary tract-associated cancer.

Abstract: Techniques and systems for providing games of chance with multiple levels of persistent features are disclosed. Some example systems include scatter prize indicators that are each associated with different symbol positions of a game of chance. When a scatter symbol is selected for a given symbol position, the scatter prize indicator associated therewith may be upgraded; selection of a sufficient number of symbol positions may result in a feature game mode being activated. During feature game mode play, scatter symbols are retained after each play of the game until either sufficient consecutive plays occur without any scatter symbols being obtained or until all symbol positions have scatter symbols. In the latter case, the scatter prize indicators are upgraded and play continues. In the former case, the feature game mode concludes. Various enhancements may be triggered based on the number of times that the feature game mode has been activated.

Abstract: An electronic gaming machine (EGM) or another type of gaming device may be configured to provide games that involve “WYSIWYG” (what you see is what you get) symbols or “prize on” symbols. The gaming device may be configured to provide the value of all “prize on” symbols that land during a single instance of a game if a prize on trigger symbol, which also may be referred to herein as a blast symbol, lands during the same instance of the game. In some examples, the game may be a base game. According to some examples, a feature does not need to be triggered during the instance of the base game for the value of all prize on symbols that land during the instance of the base game to be awarded. In other examples, the game may be a feature game, such as a “hold and spin” game.

Abstract: A breath analyte capture device includes a breath input port into which a user exhales a breath sample, and a cartridge insertion port for receiving a disposable cartridge containing an interactant. During exhalation of a breath sample, at least a portion of the breath sample is routed through the cartridge such that the analyte (such as breath acetone) is captured by the interactant. In some embodiments, the concentration of the analyte in the breath sample is measured by monitoring a chemical reaction that occurs in the disposable cartridge. The chemical reaction may be monitored by illuminating the cartridge at each of multiple light wavelengths while measuring reflected light.

In some embodiments, the branched nanoparticles are uniformly distributed in a mixed-matrix membrane. In some embodiments, the mixed-matrix membrane is configured to separate one or more gases from a gas mixture. In some embodiments, the branched nanoparticles contribute at least in part to an increase in permeability, selectivity, and/or resistance to plasticization of the mixed-matrix membrane.

Abstract: Nested frenzy modes for games of chance are disclosed. When a first frenzy mode is activated, opportunities are provided to obtain first frenzy item symbols as part of game outcomes. Each first frenzy item symbol that is obtained in an outcome may cause a number of obtained frenzy items of a featured set of frenzy items to be incremented by a first value. When all frenzy items in the featured set of frenzy items are obtained, a featured set prize is awarded and a new set of frenzy items presented. Additionally, there are opportunities within the first frenzy mode to trigger a second frenzy mode in which second frenzy item symbols are potentially obtainable. Should a second frenzy item symbol be obtained, then the number of obtained frenzy items of the featured set of frenzy items may be incremented by a second value that is greater than the first value.

Abstract: A breath analysis device into which a user exhales a breath sample is capable of venting an initial portion of the breath sample from the device, and routing a second portion of the breath sample into a disposable cartridge containing an interactant. The device may include a sensor, such as a pressure sensor, for detecting the initiation of exhalation, and may include a controller that switches a valve during the exhalation process to route a desired portion of the breath sample into the cartridge. After the exhalation process, an LED/photodiode arrangement, or another type of optical sensor, may be used to measure a color change produced by a chemical reaction in the cartridge, to thereby measure a concentration of a ketone or other analyte in the breath sample.
