Rally-X © 1980 Namco, Limited.
In Rally-X, the player drives a car around a maze picking up all of the yellow flags, of which there are ten, before the car's fuel runs out. The game-play has a similar feel to another Namco legend, Pac-Man; although in Rally-X, the mazes are much larger and, with each maze having only ten flags to collect, is more sparsely populated than Namco's pill-eating legend.
In-game opponents consist of red enemy cars that try to ram into and destroy the player's car, a problem compounded by the fact that enemy cars are faster than the player's. A smoke screen can be activated which trails behind the player's car and causes any pursuing enemies to crash. Each maze also has rock formations which, if crashed into, will result in the loss of a player car. A radar display to the right hand side of the playing area shows the positions of both the flags, and the enemy vehicles.

The special flag reappears in Xevious, released in December 1982. The flag hidden in a few areas there.

| Collected flag | 100 points x the flag collected up to a maximum of 1,000 points. If you lose a life, the points awarded will reset to 100. |
| Collected Special Flag | doubles points for the special flag and all flags collected thereafter until you clear the round or lose a life. If you clear the entire round without losing a single life, the tenth flag is always worth 2,000 points because it is guaranteed that at some point, you will have collected the Special Flag. However, losing a life will cancel out the Special Flag's scoring effect when you restart. |
| End of stage bonus | points for remaining fuel (always random). |
