Almost all words in the English dictionary are valid words. Offensive words, abbreviations, words less than 3 letters, proper nouns such as places, people, days of the week, and generally any word that is always capitalized will not count as a bonus word.
We appreciate your patience to make us better. If you have a word that you believe should be allowed or blocked, feel free to send us a support message, telling us the word and the corresponding level number!
