Since someone's curious, here we go again...

It's important to note (as I did, in the OP) that strictly speaking, chains do not have to be "closed", though they almost always are. All that is required is that the sums are linked up, not linking to each other, and partition correctly. In one level, (28, right) the game plays with an over-abundance of connections, and the task is to "disconnect" these just enough to satisfy yadda-yadda. Since I knew that this was true and did not see the solution, I did begin to consider the known possibility that such a "messy" solution might exist for 49. Fortunately I didn't waste too much more time on this idea, both as the spirit of the level (six end-connections) and the game's norm strongly pointed to the closed chains.
