The puzzle is poorly explained on the video. In puzzles of this type, it is implicit that a solution leaves every match used as the side, or part of the side, of at least one square. Solutions that, due to symmetry considerations, are essentially the same are not usually counted as distinct solutions. I have yet to see a solution that moves only three matches or that produces five squares.

I'm not sure with the 5 squares answer, but for 3 match moves to create 3 squares:

Code:
.-.-.-.

.-. . .

.-. . .

.-.-.-.
Two little squares and one big one Perhaps your criteria are more stringent?
