THE MEASURING ATELIER
Ribbon Ruler
Place the required marks on each ribbon. Every pair of marks must have a different distance. Zero is pinned. Solve five measuring puzzles.
Tap a position or its button to toggle a mark. Zero stays pinned. Place exactly the required marks with no repeated pairwise distances.
Arrows select position · Space toggles · Enter starts or continues · V inspects
U undo · C clear · P pause · R restart · F fullscreen · Escape exits.
Three failed inspections end the shift. Undo and clear are free; no time limit.
