Abstract: 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.

Abstract: A computer-implemented method of controlling a display of a computer device by: rendering on the display a game board having a plurality of selectable game objects, each at a respective tile location in an array. User input is detected to select a game object causing the game object to move in a direction. A game move is implemented in which the selected game object is moved to an adjacent new tile location and swapped with the selected game object. Match data is generated if the move results in at least three game objects of the same characteristic occupying adjacent tile locations, which are removed from the rendered image. New game objects are generated to replace the removed game objects.

Abstract: A computer implemented method of controlling a display of a computer device comprising: rendering on the display a game board having selectable game objects and detecting a user input to select a game object to cause the game object to move in a direction. When a selected game object is moved to an adjacent new tile location, the game object at that tile location is swapped with the selected game object. Match data for the selected game object is generated indicating whether the move results in at least three game objects of the same characteristic occupying adjacent tile locations in the game board, and, if so, the move is implemented and an animation of the move is rendered, wherein the selected game object slides in the direction up to a blocking condition which prevents further movement.
