Game mechanics for transformation of an array including a plurality of rows and/or columns

摘要

A method of operating a computing device includes displaying a game field including field positions with a plurality of game tiles, receiving a first user input indicating the selection of a starting field position, receiving a second user input indicating the selection of an ending field position, where the starting field position and the ending field position define a grouping of at least three game tiles in field positions between the starting and ending field positions, determining a point of rotation for the grouping, exchanging respective game tiles of the grouping from a respective first field position to a respective second field position that is calculated relative to the point of rotation, displaying the exchanged game tiles on the game field in the respective second field positions, determining that a game tile matching condition is present, and indicating the game tile matching condition to the user.
