The middle is supposed to be steam rising from a cup. The three squares on the top of the cup all has a square shaded diagonally to the right of them. Then from there its playing diagonals. Hope it helps :)
The top is also not logical because of the "V" but easily guessed by the title. the bowl of the cup is symmetrical, and the handle attaches to the cup at both ends. Then three curls of steam that zig zag, starting with moving to the right from the 1s attached to the 17.
