Press on the light source to start it. Position mirrors to bend the laser beam towards the goal. Adjust the mirrors to change the angle of the laser. Connect the laser's color with the target's color by altering the laser's color using buttons. Finish each level by lighting up all targets with the correct colored laser. Advance through challenging levels, each requiring unique approaches. Be mindful of blocks that can stop the laser beam. Utilize prisms to split the laser into multiple beams for more complex puzzles.
