Click a non-empty border position to fire a laser gun. The laser will be reflected by the mirrors, and after a few reflections will end at a second laser gun. The laser ray may not end at an empty border position. The firing laser gun as well as the targeted laser gun will disappear.

A counter on the top right will show your number of moves.
The number at the top left corner shows how many moves you have to accomplish to win.
After each move, click the same border position again to switch the laser off.

The first mirror which has been hit will change its orientation when you turn off the laser. (In some variants all hit mirrors will change orientation.) This gives a different board setup with every shot.
You lose if you are stalemated.

Solutions are attached (menu option HELP/SHOW SOLUTION). All solutions have been found by hand, so you might be able to improve on them.

In the random variants you try to eliminate hit as many laser guns as possible. When you reached a good score, start again with the same setup and try to beat your score or ask your friends to beat it.

Variants 1-10: fixed setup; only the first mirror hit by the laser flips.
Variants 11-20: fixed setup; every mirror which has been hit will flip. These latter variants are more difficult because more changes happen after each move.
Random Variants: First click the board to drop mirrors randomly.

 
The name 'Flim-E' is an abbreviation of 'flip mirrors and eliminate laser guns'.
