The object of Tunnel Runner is to successfully escape from an endless series of colorful, complex, three-dimensional mazes called Runs. To do this you must first find the key hidden in each Run. While in a Run, points are scored for every new Room you enter. Bonus points are awarded based on how long it takes you to escape from each Run.

Tunnel Runner is Balaska's first game for CBS Electronics.
The little symbol that appears on the title screen is actually the letters db (for Dick Balaska).
Starting on run 9, each run has a secret door with the initials db and cb (for the programmer's former wife, Cindy) on it. If you run up to the door, you’ll get about 1,000 points, but if you turn away after first seeing it, you won’t get any.
An addendum sheet was later included, which corrects some errors in the manual, since the game was changed prior to being released.
To execute an emergency transport, hold FIRE and rotate the joystick in either direction during a run. Note: This may only be done once per run. This feature is not documented in the manual.
