Hexjong Cats

Angela's cat lives with its owners in a cozy apartment.
Quite often, when her owners are not at home, she plays various games.
Today in the game Cats Hexjong, we will join her in this.
Our cat plays an exciting puzzle.
Before you will be visible tiles with pictures folded in piles.
You need to disassemble all these piles.
To do this, select the same two click and move them to each other.
But this can be done only when the tile is free.
That is, its movement is not blocked by other objects.
