As often happens in this forum, someone else has answered more eloquently than I but, as a solo racer, I would like to add my thoughts. My soul is my own and does not need to be 'opened'. I have many reasons for not joining a multi-player co-op and Playrix had enough foresight to offer myself and fellow solo racers that option. There is nothing wrong with it and, in fact, I find I quite enjoy it. Telling me (or any other solo racer) that I should change my gaming style in order to fit your idea of the right way to play is, in fact, disrespectful.
While I would certainly not call this particular task 'unfair' I did post yesterday that "It's the first time I've sort of felt punished for being a solo racer." so we share a similar frustration. JayS offered a very simple solution in that thread:

If you play on an Android system and are interested in trying that option please PM me so we can share co-op details and give it a shot. Barb
