The words that are accepted will depend on the language selected for the game, since each language has its own dictionary.
You cannot use proper names, acronyms, prefixes or suffixes. Some of these words might be accepted if they have more than one meaning, like some proper names or adjectives.
Bear in mind that:
- You can use letters that continue an already existing word.
- Words can be placed so that they can be read from left to right as well as from top to bottom.
- It is possible to place one word parallel to another as long as all the letter combinations form valid words.
