Girih — Star Link Puzzle

Every level in Girih has exactly one solution — and the game proves it before the level ever ships. A generator builds the board, a solver then tries to break it, and any board that can be finished two different ways is thrown away. You are never told "wrong" for an answer that was, in fact, right. WHAT MAKES THIS ONE DIFFERENT • One solution, machine-proven. Not a promise in a description — a condition of the level existing at all. • 300 levels across 10 worlds, each world named after a real motif of Islamic geometric design. • A Heritage gallery. Finish a world and its motif opens: the eight-pointed star built from two squares, the pointed arch drawn from two centres, the muqarnas that turns a square corner into a round dome, the knot that gives the word "girih" its meaning. Each one is drawn live from its own geometry — compass-and-straightedge construction lines included — not stored as a picture. • A new daily board every day, the same for everyone, with a streak. HOW IT PLAYS Drag from one node to its twin. The path may bend, but it may not cross another path. When the grid is full and every pair is joined, the level is solved. Simple to read; the later grids still make you stop and think. Undo, hints and a clean restart on every board. Progress is kept on the device. Plays entirely offline. No account, no sign-up, no purchases. In Albanian and English. A quiet game: no timer, no lives, no pressure to hurry. The Heritage Gallery: finish a world completely and it opens a card — the real girih motif behind that world's name, its history, and one named place where it can still be seen. Sultan Han, the Alhambra, the Darb-i Imam shrine. Every motif is drawn from geometry inside the game: polygonal star, rosette, tiling, two-centred arch, muqarnas, woven knot. No photographs, no downloads, nothing borrowed.
