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
- Find the server. It is the dark tile near the middle.
- Tap tiles to turn them. Join cable end to cable end, starting from the server.
- Watch the screens. A computer goes green when its cable reaches the server.
- 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.
The tiles on the floor
| Tile | Cable ends | Good to know |
|---|---|---|
| Server | 2 or 3 | The start of the network. Everything has to be joined to it. |
| Computer | 1 | Its screen turns green when it is online. It sits at the end of a cable. |
| Straight cable | 2, opposite each other | Has only two different positions. |
| Corner | 2, at a right angle | Has four positions. |
| T-piece | 3 | Has four positions. The side without a cable often belongs at a wall. |
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.
How the week gets harder
| Day | Floor | Tiles | Computers |
|---|---|---|---|
| Monday | 4 × 4 | 16 | 5 to 7 |
| Tuesday | 5 × 4 | 20 | 6 to 9 |
| Wednesday | 5 × 5 | 25 | 8 to 12 |
| Thursday | 6 × 5 | 30 | 10 to 14 |
| Friday | 6 × 6 | 36 | 12 to 17 |
Saturday plays like a Wednesday and Sunday like a Tuesday.

No. Every puzzle was checked by a program and has exactly one finished network.

A tile that was set by a hint is pinned, because it is already right. It shows a small gold dot.
