Method for controlling a user interface

A device comprising at least one processor and at least one memory in connection with said at least one processor, the at least one memory storing information associated with a plurality of first objects and one or more characteristics of said first objects, the at least one processor configured to:

• retrieve from the memory said information associated with a plurality of first game objects and one or more characteristics of said first game objects and cause said first game objects with said one or more characteristics to be displayed on a user interface in an arrangement, and to
• execute on the at least one processor at least one algorithm which:
• responsive to detected user input, selects and moves one or more of said first game objects to thereby rearrange said first game objects displayed on the user interface to provide a sequence of at least three adjacent first game objects sharing at least one same characteristic,
• determines an upgrade level of each of said at least three adjacent first game objects, and in response to said determination selecting one of said at least three adjacent first game objects for upgrading, and
• causes an updated arrangement to be displayed on said user interface with said selected one of the said at least three adjacent first game objects being upgraded and having said same characteristic and other of said three adjacent first objects being replaced with further first game objects, whereby said upgraded first game object is displayed on said user interface such that said upgraded first game object is subsequently selectable by the user via the user interface.

A computer readable storage device storing instructions that, when processed by at least one processor of a device, causes said processor to:

• retrieve from at least one memory in connection with said at least one processor information associated with a plurality of first game objects and one or more characteristics of said first game objects and causing said first game objects with said one or more characteristics to be displayed on a user interface in an arrangement,
• execute on at least one processor at least one algorithm which:
• responsive to detected user input selects and moves one or more of said first game objects to thereby rearrange said first game objects displayed on the user interface to provide a sequence of at least three adjacent first game objects sharing at least one same characteristic,
• determines an upgrade level of each of said at least three adjacent first game objects, and in response to said determination selecting one of said at least three adjacent first game objects for upgrading, and
• causes an updated arrangement to be displayed with said selected one of the said at least three adjacent first game objects being upgraded and having said same characteristic and other of said three adjacent first game objects being replaced with further first game objects, whereby said upgraded first game object is displayed on said user interface such that said upgraded first game object is subsequently selectable by the user via the user interface.
