All games are tables and they start from the upper left hand corner (except when they are mentioned to not be tables). I (VeryPunny, the creator) start with a word or phrase in the upper left hand corner, and it builds down to the lower right hand corner. Different cell colors represent different behaviors. Unless if the word is on the edge or specified otherwise (within the style links), words must be adjacent to two other words. All of this also applies to phrases.
