Cable
DraftThree or four coloured cables and one active light. The count and the light pick the colour to cut; the team turns it into a position.
First appears in level 1
How to recognise it
A panel with three or four cables side by side, each red, blue, green or yellow, and one lit indicator in one of the same four colours. The blind player feels the cables as plain outlines without colour. The very first module of the campaign.

Procedure
Feel the cables and count them from the left so you know which is which. Wait for a position, not a colour. Repeat it back ("cutting number three"), wait for a "yes", then cut exactly one cable and say "done" so nobody cuts a second one.
Common mistakes
Using the three-cable row on a four-cable board. With a blue light that is the difference between green and yellow.
Calling colours before the count, or only the light. The mute player needs all three pieces at once.
Sending a colour instead of a position to the blind player.
Cutting a second cable after the module is already solved. Say "done".
