Dart game apparatus and dart game system providing event effect

A dart game apparatus comprising:

• a dart target having a plurality of score areas;
• a sensing unit sensing a hit location of a dart pin in the dart target;
• a display unit providing a display area surrounding the dart target;
• and
• a controller determining an event effect based at least partially on the sensed hit location of the dart pin, and controlling the display unit to output of the event effect at a time subsequent to the sensing unit sensing the hit location of the dart pin in the dart target,
• wherein the display area and the dart target occupy an entire front surface of the dart game apparatus and the event effect comprises a visual effect displayed over the entire front surface of the dart game apparatus except for the dart target,
• wherein the controller is configured to:
• determines a first user area in which score information depending on dart pin throwing of a first user is to be displayed and a second user area in which score information depending on the dart pin throwing of a second user is to be displayed in the display area,
• compares score information of the first user and score information of the second user with each other and when superiority between the score information of the first user and the score information of the second user is changed, allows a reversal event effect to be output to at least one area of the first user area and the second user area,
• determines at least one of a type of an image to be output to the display area and a location of an area to which the image is to be output in the display area based on identification information of one of the first user and the second user who throws the dart pin, respectively, the type of the image and the location of an area to which the image is to be output in the display area being different for the first user and the second user,
• determines an event effect to be displayed and a location where the event effect is displayed in the display area at least partially based on the hit location of the dart pin in the dart target, and
• determines, pre-event generation, whether a predetermined event occurs at least partially based on progress information of a dart game which is currently in progress before the dart pin is thrown;
• and
• determines a location of a pre-event generation effect to be displayed in the display area is to be output based on an event which occurs when the predetermined event occurs.
