You can't skip or "jump" across letters. - Words must be at least three letters long. Very short words, like "I," "an," and so on are not allowed. - Words can go in any direction. The words you find don't have to go right-to-left. They can go up, down, backwards, forwards, and diagonally as long as all of the letters are connected in a chain. - Count each word only once. - Any word found in an English dictionary is allowed. - Plural forms of words count as separate words. For example, if you see the word "cars," you are actually allowed to write down two words: "car" and "cars" - Words-within-words are allowed. For example, if you see a word like "Webster," you can also write down "web" "webs."
