The idea of Cruising is to get round a course, which is a single pixel line, without being caught by the computer's opposition car. The initial course is a double figure of eight, whilst the subsequent courses, which you get onto once the previous one has been completed, are far more random (there are four in all).
Initially, the game is disappointing with only coloured squares as cars and a single line as the track. Also, you only have one life per game; therefore, the game can be rather short. If you get past the lack of initial impact you should find yourself enjoying this simple game.
The game is good in its addictive quality, but lacks the substance really to be sold on its own. If there were two games of equivalent standard to this on the tape, then it would be better value. Apart from this, you can not take away the fact that it is quite definitely fun to play.
