Purpose of this game is to find out the hidden arrangement of mirrors by looking what happens when you fire a laser. To fire a laser, click on any of them, look for green light to see where it ended up to.
You can click on any tile on the grid to the kind of mirror you think it holds. Once you get the same setup as the hidden setup is, game ends. If you click 'Expose', the game ends.

The level generator is set to generate at max 5 mirrors. It is supposed to generate 5 mirrors, but due to the buggy nature of the algorithm, I can only let it try limited times to get the level right. This quite often leads to having less than 5 mirrors.
