Abstract: A computer device has a user interface which displays user actuatable game elements. User input is received and used to determine if there is a match involving three or more game elements. If so a check is made to see if one of the game elements is of a particular type. If so the size of the particular game element is determined to see if it is the smallest size. If not at least two further game elements of the given type are provided with a smaller graphical representation as compared to the at least one game element of the given type in the match game condition.
