Hi Martin
Yes I have played this game on many occasions, it's a bit of fun, difficult to beat the opposition.
Have even set the game up and run it as a competition for the juniors at the Brighton Modelworld and presented a small trophy to the fastest score on each of the 3 days at the show. The kids seemed to enjoy it very much, many of them coming back during the day to see if their score had been beaten and to have another go.
