Cable Run: A Free Daily Network Puzzle

Cable Run is a free daily puzzle. Someone has pulled the office network apart, and most of the cable tiles now point the wrong way. Tap a tile to turn it. Cables that reach the server light up green, and the computers on them go online. You win when every computer is connected. Monday is a floor of 4 × 4 tiles. Friday is 6 × 6.

No sign-up and nothing to install. It runs in your browser on a computer or a phone, and your progress is saved on your device.

  • One tap, one quarter turn. Tap a tile to turn it to the right. With a mouse, a right-click turns it to the left.
  • Green means connected. You always see how far the network reaches from the server.
  • One answer. Every puzzle has exactly one finished network, with no loose cable end and no loop.
  • Stuck? The lightbulb turns one tile to the right position and pins it. Hints and undo are free.

How to play Cable Run

  1. Find the server. It is the dark tile near the middle.
  2. Tap tiles to turn them. Join cable end to cable end, starting from the server.
  3. Watch the screens. A computer goes green when its cable reaches the server.
  4. Keep turning until every computer is online. In the finished network no cable end points at a wall or at a blank side of a tile.

Tips for wiring the floor

  • Start at the walls. A cable end never points at a wall. A straight cable at the edge runs along the wall, and a T-piece at the edge has its blank side to the wall.
  • Check the four corners of the floor. A corner piece there has only one position that keeps both ends inside.
  • Two computers never join only each other. They would be cut off from the server, so at least one of them points somewhere else.
  • Follow the green. When a green cable end points at a tile, that tile must answer with a cable end of its own.
  • No loops. If a position would close a ring of cable, it is the wrong position.
