This looks like a puzzle to touch a 4x4 array of dots

with 6 connected line segments.

a. Is that the idea?

b. Did you mean 4x4 and not 3x3?

a. I'm asking whether that was the meaning. I don't think it has been previously posted.

Most of the connect-the-dot solutions i goggled are incompatible to this. For some are blocked by mirror or hit a switch twice..

..anyway since this is the oldest pending topic I posted

I would say that I only need four mirrors, as long as they're large enough.

The beam enters through the upper left and leaves through the lower left, bouncing off the purple mirrors which are right next to the sensors on three sides and 1/2 of a square away on the other side. I get to hang the fifth mirror up on a wall at home.

but then again hitting the switches twice toggles them off..
