OnlyOneConductor is a puzzle game by momopey, officially released on August 4, 2019. The game draws inspiration from Zach Barth's KOHCTPYKTOP: Engineer of the People, focusing on the creative potential of a minimalistic design.

In OnlyOneConductor, players build circuits using only one conductor and a single logic gate, the NAND gate, challenging them to think critically about circuit design. The gameplay revolves around painting circuits with a unique path mechanic that encourages experimentation and problem-solving.

The storyline of OnlyOneConductor is minimal, centering on the exploration of logic and circuitry through a series of increasingly complex levels that test the player's ingenuity.

OnlyOneConductor stands out with its innovative approach to circuit-building, offering a fresh take on puzzle mechanics by limiting players to a single component, thus fostering a deeper understanding of logic gates and their applications.
