MergeBalls Shows in BoobyRoofs city

As you know, BoobyRoofs city has a lot of entertainment points and erotic shows. But now you get into the very unusual block, with MergeBalls Shows. There are 16 buildings in this block with opened roofs. And sometimes balls with numbers appear on these roofs. You may enter the building, and take the ball. Go with this ball to another building, and "merge" your ball with ball there, if both balls have equal numbers. When balls merge, the new ball receives the value of the sum of those merged balls (2+2=4). When you merge balls, the TV set in this room switches ON. Also there are several Live Shows in this block. To start the show, you must merge there two balls, to receive the next higher value. (If current reached value was 4, you must merge two balls with values 4, to receive new higher value = 8.) Live Show usually have 2 scenes, so come again and watch 2nd part! Switch On all TVs and watch all Live Shows in this block to fulfill your mission.
