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, absorbing element, light warp (or tunnel). Select the size of the grid and the number of item to place. 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 using the hint mode to display the ray trajectory.
Hint: start with a low item number, without options.
