Abstract: A gaming system including a processor and a memory storing instructions thereon which, when executed by the processor, cause the processor to: select symbols from reel strips stored in the memory for display in corresponding columns by determining stopping positions for the reel strips; cause display of the selected symbols in the columns on a display of a gaming device; determine that a trigger condition stored in the memory is satisfied based on the selected symbols; and in response to determining that the trigger condition is satisfied: replace one or more of the selected symbols in a group of symbol positions with an animation effect, the animation effect including display of a spin and stop sequence of credit values in the group of symbol positions; select a subset of the credit values; and cause display of the subset of credit values in the group of symbol positions.

Abstract: In one aspect, an electronic gaming system is provided. The electronic gaming system may cause to be displayed on a display device a game interface including a matrix having a plurality of symbol positions for displaying a symbol within each symbol position, generate, based on an RNG call outcome, an optimal game outcome, programmatically select a suboptimal game outcome based on the generated optimal game outcome, display at least a portion of the suboptimal game outcome in the matrix, cause to be displayed a prompt to select from a plurality of user options to modify at least one symbol of the at least a portion of the suboptimal game outcome displayed in the matrix, modify, based on a selection received from a user of one of the plurality of user options, the symbols displayed in the matrix, and determine if the optimal game outcome is displayed.

Abstract: A method for preventing an electrical grid from failure in case of a temporary overvoltage includes providing an electrical grid line, a surge arrester and a disconnector device with a disconnector unit. The method further includes connecting the surge arrester at one terminal to the electrical grid line, connecting the surge arrester at its other terminal to a first terminal of the disconnector device, and connecting a second terminal of the disconnector device to ground potential. The method further includes interrupting the electrical connection in between the electrical grid line and the ground potential in response to a temporary overvoltage. The method further includes protecting the surge arrester from failure due to a thermal overload caused by the temporary overvoltage by operating the disconnector device before the surge arrester fails due to a thermal overload of the surge arrester.

Abstract: This disclosure concerns a disconnector device for a surge arrester. The disconnector device comprises a housing encompassing a cavity and a disconnector unit provided inside the cavity. The disconnector device is connectable to the surge arrester and to ground potential. The housing forms an inner housing of a housing unit. The housing unit comprising an inner housing and an outer housing. The at least one ventilation opening of the inner housing is fluidly connected to the at least one further ventilation opening of the outer housing such that a labyrinth with a gas escape path for the gases from the operating disconnector cartridge is formed.
