Tonight WGT updated the Apple IOS version of WGT Mobile. One of the changes was to add the capability to play the clashes on Iphones and Ipads. So Now the mobile only players who were being left out of the clashes can join in and play them too.
As I haven't even had my Android tablet powered up in weeks I don't know if they updated the Google Android version or not. They don't always update them at the same time.
