A computer game includes a procedure of aligning objects in a field. The procedure includes a series of sub-procedures each including creating and positioning a new object within the field and moving the new object within the field. Moving the objects occurs regardless if the object is moved above one or more other objects. It is detected if the object is situated above one or more other objects and if a complete column and/or row within the field is filled with one or more parts of the objects. If no object is positioned above any other object and a complete row and/or column is filled with the objects or parts of the objects, the objects or the parts of the objects which are positioned within that column and/or within that row are removed from the field. The computer game is applicable for storing objects in a storage-device, as an adult-check, identity-check or as an intelligence trainer.
