The String Board

Matching, rebuilt as an evidence board. Pinned cards, real sagging yarn, wrong throws that snap with a wobble. When the board is solved, it hands over the tangle report: exactly which pairs got confused, kept on this page and nowhere else — with one tap to replay them, or duel them head to head.

Why a board beats two columns

Columns let students match by elimination — the last pair solves itself. A scattered board makes every throw a decision, the yarn makes each decision physical, and the tangle report turns wrong answers into the lesson plan: the game tells the student what to study. Classic two-column matching is still one toggle away in the editor; the board is a way of seeing the same pairs.

string-board — the repo

The board, the yarn physics, the deterministic scatter, and the confusion tally are being cut into their own open-source library — this page is its live demo.
