URN · Puzzle experiments

Three experiments on the same equilateral board: explore movement, edge matching, and corner-digit deduction.

3 · Corner logic

The new deduction experiment: fill missing corner digits. Each gold hub sees 1–6 exactly once, and each tile has a total. No movement; focus on the logic. Includes pencil notes and explained hints.

2 · Edge matching

Three digits from 1–5 on each tile. Match the digits across every shared edge. Tile identities are hidden, so there are no visible destinations.

1 · Movement lab

The previous numbered-tile puzzle, with rotating labels and animated edge flips. Restore the original positions, faces, and orientations.
