Solutions are not unique; not “solvable” – Number Chain - Logic Puzzle Review

One simple change would make this so much better, but the ending number of the chain isn’t always provided. This leads to multiple solutions being possible. The “1” is always provided, so I don’t know why the last number isn’t necessarily. I wish the “erase” also worked by dragging. Other than that, the interface feels slick and I enjoy playing.
