A method of controlling a user interface having a display area comprising a plurality of game objects. The user interface also displays at least one other object, such as, for example, a displayed score. In a situation where the object at least partially overlay and at least partially obscures at least one of the game objects, then in response to a trigger condition a display characteristic of the object is modified to improve visibility of the at least one displayed game object. The trigger condition is, in one example, detecting user input associated with the at least one game object. The display characteristic of the object is, in one example, a transparency factor of the object. Therefore, it can be ensured that elements or information can be made visible to a user, as required.
