Word Bubbles and Word Bubbles Rising look up words in a fairly large dictionary, so they should include common words in both American and British English, but may omit some technical terms and newer words. Neither game will accept any of the following words:
Word Bubbles and Word Bubbles Rising will NOT accept
- Contractions (words containing apostrophes such as "can't")
- Slang (words that have not been recognized by a reputable dictionary)
- Proper nouns (words that start with an uppercase letter such as California or Christmas.) If a word that is a proper noun is accepted it is because there is also a common noun definition of this word.
