Racetrack: The True Story of the Classic “Pen and Paper Grand Prix
Share
If you ever grabbed a graph paper notebook and two pens of different colors to race around a hand-drawn track, you’ve probably played Racetrack — also known as the “Paper Grand Prix.” It’s one of those brilliantly simple games that turns mathematics and logic into pure fun.
Also called Vector Formula, Vector Rally, Vector Race, Graph Racers, Paper Racing and more, Racetrack is a pen and paper racing game where each line you draw represents a “gear” or velocity. Step by step, players plan their moves, accelerate, brake, or steer — and just like in real racing, too much speed in a corner will send you off the track.
📜 When did Racetrack start?
The exact origins are unclear, but the game was already circulating in Europe in the 1960s. It was “officially introduced” to a wider audience in January 1973, when famous mathematician Martin Gardner featured it in his Mathematical Games column in Scientific American. That same year, Car and Driver magazine described it as a surprisingly realistic simulation of racing on paper.
Gardner credited computer scientist Jürg Nievergelt, who had learned the game in Switzerland. From there, Racetrack spread across classrooms and hobby groups worldwide, becoming both a pastime and a teaching tool.
🧮 Why is it so clever?
Each move in Racetrack is essentially a vector. On your turn, you can keep the same vector as before (same speed and direction) or adjust by moving to one of the eight surrounding grid points — the equivalent of shifting gear or steering.
This simple rule set creates astonishingly realistic trajectories: if you enter a corner too fast, you’ll overshoot and crash; if you brake too much, you’ll fall behind. That’s why the game is often used to teach vectors, acceleration, and prediction in math and physics classes.
🏷️ So many names, same game
Depending on the country or community, Racetrack has appeared under many names: Vector Formula, Vector Rally, Graph Racers, Paper and Pencil Racing, PolyRace, and more. Small rule variations exist (like limiting moves to 4 directions instead of 8, or adding “slippery zones”), but the core remains the same: graph paper, a start/finish line, and vector-based movement.
