You are in a square room protected by laser beams and are trying to make it from the top left corner to the bottom right corner without being hit by a laser beam.
Click any empty position on the board to start the lasers. Then can go one step at a time in any orthogonal direction. With SmartMoves activated (menu option View\Options\Board\SmartMoves) simply click the target square to move your token.

The purple squares are obstacles you cannot step onto. The obstacles are transparent to the lasers, however.

The lasers are emitted by blue and yellow boxes which alternatingly turn on and off with each of your steps.
You can step to a position that is currently illuminated by a laser, since this laser will turn off next.

You win when you have reached the green position in the bottom right corner.
Solutions are attached.

There is also a randomized variant attached. Note all problems in this variant may be solvable.
