Reshuffle

Swap given pair of items, moving objects from one square to another.

The item should only be moved to a free square.

You can’t move objects diagonally.

You can’t carry one item over another.

You can’t put more than one object in the square.

The game has many solutions, but it's interesting to find the shortest.

Just in case, the hint that the required minimum number of moves is more than a dozen, although less than one and a half dozen.
