Numberlink Line Puzzle: Filum

Filum is Numberlink — also called Number Link or Arukone — the classic pencil-and-paper line puzzle: connect matching numbers with one unbroken line, fill every cell of the grid, and never cross another line. Every puzzle has exactly one solution. HOW TO PLAY • Drag from a number to its twin to draw a line between them. • Lines run across and down. They never cross and never branch. • A puzzle is solved when every pair is connected and every cell is filled.
