===The moves===
[[File:Racetrack game move.png|thumb|One move in the graph paper game Racetrack. The player's previous move is shown in blue; their next move may be to the ''principal point'' marked in red, or to any of its surrounding squares, shown in green.]]
All moves will be from one grid point to another grid point. Each grid point has eight neighbouring grid points: Up, down, left, right, and the four diagonal directions. Players take turns to move their cars according to some simple rules. Each move is marked by drawing a line from the starting point of this move to a new point.
* Each player's first move must be to one of the eight neighbours of their starting position. (The player can also choose to stand still.)
* On each turn after that, the player can choose to move the same number of squares in the same direction as on the previous turn; the grid point reached by this move is called the ''principal point'' for this turn. (E.g., if the previous move was four squares to the right and two squares upwards, then the principal point is found by moving another four squares to the right and two more squares upwards.) However, the player also has the choice of any of the eight neighbours of this principal point.
* Cars must stay within the boundaries of the racetrack; otherwise they crash.
