Thanks!
Well it wasn't a proper chain if it wasn't completely linked. The biggest thing in scoring well is to realize that you always will have the whole deck if you play until the very last cell. So you can just dedicate certain cards as transitions between suits, reserve a space for em and they will come at some point. Then it's just all about not making accidental transitions to where you don't want.
Had stuff like this happen to me too many times during the development. Carefully constructing a whole board of a chain and then to just realize that there is an accidental missed turn right in the beginning.
