Laser duel was a recreational game popular in the 24th century. The game was played with a laser pistol. A standard game required twenty-one points for a win. One of the objectives was worth four points.
Ogus II was home to several arcades offering laser duel matches. In 2367, while describing to William T. Riker how his brother Willie Potts had gotten exposed to a cove palm parasite, Jake Potts explained that they had programmed the arcade's game for an ordinary laser duel, describing the rules. Riker interrupted him midway, saying he was familiar with the game. (TNG: "Brothers")
