The User Interface that I used for TheSOSGame was very reflective of how you would play the game on paper. You would choose your spot and make sure you were happy with it. Write down your S or O and then once you lifted your pen from the paper that was it. Not going back. So in my iPhone implementation I tried to emulate that with the concept of locking your select in. Until you locked it in then you where free to change your mind but once you locked it in that was that.
But I started to realise that this made for an unnecessary extra step in my game. You didn't need to lock it in. We had an unnecessary step that was potentially (and really) a cause of confusion. So with version 1.2 it will be gone. This has meant a redesign in the UI that means you now: 1. Select your square to rotate, then you end your Turn. 2. If you can stroke then you do it and the selections you make will be automatically locked in for you. I hope that simplifies things.
Turkey is still going crazy we are now 4th most popular free Game and the 8th most popular free app. I know it doesn't mean much in the scheme of things as Turkey is such a small Store. But it is great to get a idea of how the chimney effect works (i.e. once you get high enough in a section you shoot straight up due to the momentum of your rank (which only increases as you go up)).
