Product War

From BluWiki

The board must be full, and the product of the sizes of the two largest red groups must be larger than the product of the sizes of the two largest blue groups. If there is only one group in a given color, the product is defined as zero. The picture below shows an example in which the product of the two largest red groups is 27*46=1242 and the product of the two largest blue groups is 7*30=210.
