Nice job. I'd seen similar things in the past but I had no idea this was an actual type of puzzle.
Your game has a bug which is relatively common in drag-and-drop games. If the viewport is smaller and I drag a match off-screen by accident, it can get stuck to the edge. Then it can become detached in such a way that makes it impossible to recover the match.
