Rules: Place the mirrors in the grid, using laser. Laser rays follow the usual reflection law. Diagonal, vertical and horizontal mirrors are possible as well as total reflection (square). There is one absorbing element, without reflection (X). Select the size of the grid and the number of item to place. It is possible to reject total reflection items (vertical, horizontal and square) and/or the absorbing item in the option menu. Numbers on the edges show the number of blocks the laser ray crosses until output or absorption. Grey color indicates an absorbed ray. Yellow color indicates a reflected ray (input=output). Click on the edges when the solution is displayed to see the ray trajectories and understand how it works. Hint: start with a low item number (3).
