Players change direction via a set of four buttons representing up, down, right, and left respectively. A player loses when they hit a wall, their own dominos, or their opponent's, at which point all the dominos in their line "fall" down. A point is awarded to the winner of each round until the end point goal is reached. The point goal can be 3, 4, 5, or 6 points.

Dominos was programmed by Dennis Koble. He had joined Atari in 1976 and was only the fourth programmer at the company. His first project was Sprint 2 (1976) made with Lyle Rains and Dan Van Elderen. Koble stated that despite being credited as the programmer on Dominos, Rains was "the brains behind the game" and had suggested the concept, drew the graphics and created the AI for the computer-controlled opponent. Following the release of Blockade by Gremlin Industries, Atari wanted to make their own version of the game. Koble said the game was not stolen from Blockade, stating that prior to Gremlin's release, he had seen similar snake video games on ARPANET and CompuServe, which made him believe he was not copying Gremlin's game. Among the additions made to the game, Koble included a computer-controlled opponent, which meant that a single-player mode was possible. Koble claimed that the game was made in a short amount of time, estimating it took about 13 weeks to complete. He recalled that the game was created when Atari was still a "young company and just trying to survive as they made the transition into using microprocessors. They didn't quite have the standards they developed later".
