Drag one road from ① through every town. Rivers can only be crossed on bridges, the way the arrow points. Landmarks in number order.
The map is folded away. Clock's stopped.
• Start on landmark ① and drag through neighbouring towns (no diagonals).
• Visit every town exactly once.
• Blue rivers block you — except at a wooden bridge, which only goes the way its arrow points.
• Reach landmarks ②, ③… in order.
• Drag backwards to undo. Keyboard: arrows, Backspace.
Most maps have more than one valid route. After you solve it, see how many travellers took the same road as you.
