Qix

Qix[a] (/ˈkɪks/ KIKS[b]) is a 1981 puzzle video game developed by husband and wife team Randy and Sandy Pfeiffer and published in arcades by Taito America. Qix is one of a handful of games made by Taito's American division (another is Zoo Keeper).[4] At the start of each level, the playing field is a large, empty rectangle, containing the Qix, an abstract stick-like entity that performs graceful but unpredictable motions within the confines of the rectangle. The objective is to draw lines that close off parts of the rectangle to fill in a set amount of the playfield.
