Computer system managing multi-user rewards

A device having:

• a display;
• a user interface, said user interface being configured to receive user input;
• at least one processor;
• and
• at least one memory, said at least one processor configured to cause:
• displaying on said display of the device a first set of one or more first game objects on a level selection screen, said level selection screen allowing a user to select via a user interface one of a plurality of different levels of the computer game from the plurality of different levels displayed on said level selection screen, wherein selection of said level causes a game level screen to be displayed to allow said user to play that level;
• in response to user interaction via the user interface with one or more of said one or more first game objects which are displayed on said level selection screen accumulating one or more collectable game objects without leaving said level selection screen, said one or more collectable game objects comprising or associated with said one or more first game objects;
• and
• displaying on said display a second set of one or more of said first game objects on said level selection screen, wherein at least one collectable game object from said second set is accumulatable by user interaction via the user interface with one or more of said first game objects of the second set, and wherein said second set from which at least one collectable game object is only provided if the user has played at least one level of said computer game since accumulating one or more of said collectable game objects from said first set.

A computer readable storage device storing program code instructions that, when executed by at least one processor cause:

• displaying on a display of the device a first set of one or more first game objects on a level selection screen, said level selection screen allowing a user to select via a user interface one of a plurality of different levels of the computer game from the plurality of different levels displayed on said level selection screen, wherein selection of said level causes a game level screen to be displayed to allow said user to play that level;
• in response to user interaction via the user interface with one or more of said one or more first game objects which are displayed on said level selection screen, accumulating one or more collectable game objects without leaving said level selection screen, said one or more collectable game objects comprising or associated with said one or more first game objects;
• and
• displaying on said display a second set of one or more of said first game objects on said level selection screen, wherein at least one collectable game object from said second set is accumulatable by user interaction via the user interface with one or more of said first game objects of the second set, and wherein said second set from which at least one collectable game object is only provided if the user has played at least one level of said computer game since accumulating one or more of said collectable game objects from said first set.

A server in communication with a user device, said server configured to:

• receive from said user device a message indicating user input via a user interface;
• in response to said message transmit a collectable game object of a set of collectable game objects to said user device, said collectable game objects comprising or associated with a first set of first game objects displayed on a display of said device on a level selection screen, said level selection screen allowing a user to select via a user interface one of a plurality of different levels of a computer game from the plurality of different levels displayed on said level selection screen, wherein selection of said level causes a game level screen to be displayed to allow said user to play that level;
• and
• signaling the user device to display a second set of one or more of said first game objects on said level selection screen, wherein at least one collectable game object from the second set is accumulatable by user interaction via the user interface with one or more of said first game objects of the second set, wherein said second set is only provided if the user has played said computer game since accumulating one or more of said collectable game objects from said first set.

A computer implemented method for controlling the exchange of game objects between a database and a user device comprising:

• a user interface, at least one memory, and at least one processor in connection or communication with at least one memory, the method comprising the steps of:
• receiving from said user device a message indicating user input via said user interface;
• in response to said message transmitting a collectable game object of a set of collectable game objects to said user device, said collectable game objects comprising or associated with a first set of one or more first game objects displayed on a display of said device on a level selection screen allowing a user to select via a user interface one of a plurality of different levels of a computer game from the plurality of different levels displayed on said level selection screen, wherein selection of said level causes a game level screen to be displayed to allow said user to play that level;
• and
• signaling the user device to display a second set of one or more of said first game objects on said level selection screen, wherein at least one collectable game object from said second set is accumulatable by user interaction via the user interface with one or more of said first game objects of the second set, wherein said second set is only provided if the user has played said computer game since accumulating one or more of said collectable game objects from said first set.
