Speed Circuit is a Game that is unlike no other,where only your Skill and Strategy will Gain you success, there is no luck in this Game only your Ability.
You can Race on 3 Different Tracks (Monza,Monaco & Watkins Glen) .
You must set up your Car to give you the Best Performance to suit each Track, Every Car Starts equal then you are allocated 5 Points which you can use to enhance your Car 
in 5 different Specifications (Start Speed,Acceleration,Deceleration,Top Speed and Wear) so for example Spending 1 point on Start Speed will allow  your Car to start at 60 MPH instead of 40 MPH, Top Speed - 2 Points will allow your Car to reach 180 MPH instead of 140 MPH, etc etc.
This Game takes into account all the Drama of Real Motor Racing ,with Start Speed,Acceleration ,Deceleration,Top Speed,Tyre/Brake Wear,Reaction Times,Collisions,Slip Streaming
and for those not able to participate in a Real Race against up to  6 of your Friends then this is the Next Best Thing.
The Game is for 2 to 6 Players , Aged 12 Years to Adult.

The Game is Complete and the Contents are in Excellent Condition- (The Pad looks unused and the Board still Crisp so I believe this Game could be Unplayed)
The Box is in Very Good Condition for its Age.
