An electronic dartboard apparatus with an “in-play” scoring area that includes a plurality of narrow concentric circular areas, as well as a plurality of narrow straight-line areas which extend from the innermost circular area, through the interior circular areas, to the outermost circular area. The outermost circular area serves to distinguish between the “in-play” and “out-of-play” areas. The distinct color of the narrow concentric circular and straight-line areas makes them distinguishable from the rest of the board, creating very clear boundaries between all the other scoring areas that make up the “in-play” area. Both the narrow circular and straight-line areas are flush with the rest of the dartboard, and include scoring holes identical to those throughout the entire “in-play” area, thus making the “in-play” surface one continuous, very precise scoring area, where darts no longer bounce off the board, and fail to register the proper score.

An online dart competition system including at least two mobile devices having a first and a second image capturing module, configured to capture an dart player image and a dartboard image, respectively; a mirror to reflect/redirect the dartboard image; a wireless transmission module, configured to transmit a score, the dart player image, and the dartboard image to the other mobile device and to receive a score, image, and a dartboard image of a competitor from the other mobile device; and a processor. The processor executes an application and displays the scores and at least two images of the dart player image, the dartboard image, the competitor image, and the competitor dartboard image on a display in a split-screen interface. Thus, the at least two images may be viewed by players during the online competition.
