Laser Puzzle (Posted on 2007-10-22) Difficulty: 2 of 5
Below is a laser puzzle.

A green laser (top row) enters a grid from above and the goal is to make the laser pass through all the targets (O) by redirecting the laser using mirrors (as in the corners of the grid) which turn the laser 90 degrees.

The laser's path may cross itself in an empty square or at a target, but the laser stops if it hits the outer wall or if it hits the backside of a mirror.

Find a solution that uses as few mirrors as possible.

Brian Smith,
This is a rather neat package as an intro to the package which you have suggested has a link in your solution.

Now, some of us have enjoyed the game that has been proposed.

Note, I mentioned 'intro' earlier.  I shouldn't "market" this freebie challenge further.

By the way, the image, well provided by Gamer, is typical of what you might expect in the game set.

BS, I still haven't cheated on the short set of 11 ... (giggle ...  I still have that earlier version ... naughty am I not!?)
