The objective of LaserBox is to detect and avoid uncovering the hidden mirrors within a grid of boxes. To discover mirrors, you must fire a laser into the boxes and note which way the laser is bouncing from within the covered boxes. If you uncover a mirror by accident, the game is over.
To place a laser, click a spot from around the grid of boxes, this will open a menu where you can choose between "Laser" and "Impulse". "Laser" is a continuous beam that goes from the source, through the grid.
"Impulse" is a short beam that moves slowly throughout the grid. It has a limited flight length. The flight length is determined by the size of a field. The more the size of a field, the can longer fly an "impulse".
The first dial shows how far "impulse" has traveled.
