Pong is the game that started the commercial video game industry. Released by Atari in November 1972, it was the first arcade video game to achieve mainstream commercial success — not merely a novelty but a product people actively sought out and paid to play repeatedly. The game's premise was almost absurdly simple: two paddles, a ball, a score. Yet that simplicity was precisely the point. Pong proved that video games could be a business.

The Atari Origin Story
Pong was not supposed to be a product. Nolan Bushnell, co-founder of Atari, assigned it to a new engineer named Allan Alcorn as a training exercise — a way to learn the company's development process. Bushnell told Alcorn to build a simple tennis game, similar to what he'd seen on the Magnavox Odyssey console. Alcorn spent several weeks building the prototype, adding one embellishment beyond the brief: he divided each paddle into segments, with ball return angle varying depending on where contact occurred. This was entirely his own invention.
When Bushnell saw the result, he recognised its commercial potential and placed a prototype unit in a Sunnyvale, California bar called Andy Capp's Tavern in September 1972. The machine broke within days — not from a malfunction, but because players had inserted so many quarters that the coin mechanism jammed. Atari received a service call reporting the machine was broken and found it stuffed with coins. They went into full production.
The original Pong cabinet was a simple wooden box with a black-and-white monitor, two knobs (one for each paddle), a coin slot, and the game title painted on the side. It sold 8,000 units in its first year at $1,095 per unit — remarkable for a market that barely existed. Competitors released clones within months, a pattern that would repeat throughout video game history. Atari's success with Pong directly enabled the founding of what became the game industry's first decade.
The Rules of Pong
Pong simulates a simplified table tennis match between two players — or one player against an AI opponent. Each player controls a vertical paddle on their side of the screen. A square ball bounces between paddles and off the top and bottom walls. If the ball passes a paddle and reaches the back wall, the opposing player scores a point. First to reach the target score (usually 11 points) wins the match.
The ball accelerates slightly with each consecutive paddle hit in a rally. Long volleys become increasingly intense as the ball speeds up — both players must track a faster and faster trajectory, reacting more quickly and more precisely. This natural difficulty ramp rewards sustained accuracy over burst speed.
How to Play Pong
- Choose your mode — Select single-player (vs AI) or two-player (local) mode. In two-player, both players share the same keyboard.
- Move your paddle — Player 1 uses W (up) and S (down). Player 2 uses Up and Down arrow keys. Paddles move vertically only — no horizontal movement.
- Return the ball — Position your paddle to intercept the ball before it reaches your back wall. The ball bounces off paddles and top/bottom walls.
- Use paddle angles — Contact near the centre of your paddle returns the ball at a shallow angle. Contact near the top or bottom edge returns it at a steep angle. Use this to control where your return lands on the opponent's side.
- Force your opponent out of position — Aim returns toward one edge of the opponent's side, then aim your next shot to the opposite edge. Forcing lateral movement creates openings. Against the AI, steep-angle returns are often more effective than flat ones.
- Score 11 points to win — A point is scored when the ball passes the opponent's paddle. First to 11 wins the match.
Playing Against the AI
The Pong AI tracks the ball's position and moves its paddle toward the predicted intercept point. It is not perfect — it has a maximum speed and a slight reaction delay, which creates exploitable windows. Returning the ball at steep angles forces the AI to travel farther per volley than flat returns do. Alternating between top and bottom angles is consistently more effective than trying to beat the AI with speed alone. The AI in classic Pong was designed to be beatable without being trivial — close games are the intended experience, not easy wins.
