WordUnscrambler.com is used to find the words with the most value in a Scrabble hand. It is an unorthodox way of playing Scrabble, as it gives the player an unfair advantage over someone who is not using a program. It is not recommended to use this when playing a serious game of Scrabble with others, but it should be used as a tool to help further one's Scrabble vocabulary.
Anagram-Solver.net can take a word or phrase and rearrange the letters to form a new word or phrase. For example, an anagram of the word "burned" is "burden." This is a fun tool to use with names of friends or celebrities, as the program can output amusing answers.
Text Twist offers services similar to Word Unscrambler but has additional features of using an unknown letter or fixed prefixes and suffixes. This can be used for crosswords as well as Scrabble, where certain letters can vary depending on the situation, or suffixes and prefixes can be tagged on to increase the word value.
