Pockets Girls-4

The billiard table is divided in 4 sectors, and each sector has its "Pocket Girl".  But this time there are 2 pockets in each sector. One pocket is "positive" ("+"). And another pocket is "negative" ("-"). When any ball gets to the positive (+) pocket, this sector girl strips to the next level. But, if some ball gets to the negative (-) pocket, the girl of this sector dresses back. Your aim is to undress all 4 girls to the highest 5th level.  But, your opponent (as always) wants to dress back all girls.
