Darts
Darts was an ancient Earth game of hand-eye coordination and skill with roots in medieval England. A dart, a small version of an arrow, was thrown against a circular board that was divided into zones that awarded different point values. In the 20th century, darts became a popular recreational activity in British pubs and a casual sport around the world.

Iotian boss Jojo Krako had his own version of darts in which the dartboard was an image of his rival Bela Okmyx. This particular dartboard had targeting circles in Bela's face and his heart region. The text "Bela Okmyx" was also depicted. ()

One of the bar patrons at the San Francisco bar in 2285 played darts. ()

In 1947, Quark cited darts, along with baseball, root beer, and atomic bombs, as an example of what the Ferengi had learned "watching" Humanity. ()

In 2371, Miles O'Brien, Chief of operations on Deep Space 9, introduced the game of darts to the station, placing a board in one of the cargo bays. This recreation started during Keiko's months-long absence while she was participating in a bio-survey on Bajor. ()

O'Brien convinced Quark to put up a dart board in his bar, arguing that no bar would be complete without one. () He and Doctor Julian Bashir regularly enjoyed playing the game. At one point, O'Brien achieved a 47-game winning streak while he was, as he put it, "in the zone", which was only halted by an unfortunately timed shoulder injury. () When Bashir's genetically-engineered past was revealed, including his improved hand-to-eye coordination, O'Brien insisted that Bashir stand further away from the board in order to make their games more fair. ()

When Worf was assigned to Deep Space 9 in 2372, O'Brien jokingly described darts as "like poker, but with pointed tips" and that it was "like target practice." () O'Brien and Worf played darts together later that year, although O'Brien had just returned from Argratha and was still suffering from the Argrathi Authority's mind-altering punishment and could not remember how to play the game. ()

A pair of Nausicaans made a game of their own using the darts while in Quark's in 2372, which involved throwing the darts, point first, across the room into each other's chests. ()

In 2373, a Changeling posing as Doctor  claimed to O'Brien that he had ordered two sets of new duridium alloy darts that he had told him about. O'Brien was shocked that he would be thinking about darts when they were facing a major interstellar war. ()

During the Battle of Cardassia in 2375, O'Brien told Bashir he would miss playing darts with him when he and his family moved to Earth. ()

In 3190, Ensign Adira Tal was playing darts in the  bar, and shared with Dr. Hugh Culber their unease over the possibility of losing Gray Tal during Gray's reincorporation. ()
