LettersJam was inspired by Australian SBS TV's Letters and Numbers Quiz Show, in which two contestants try to find the longest word possible from nine randomly chosen letters consisting of a predetermined number of consonants and vowels.
LettersJam will make a great tool for those teaching or learning the English Language; also for those wanting to broaden their vocabulary.
It comes with a default (built-in) dictionary but you can choose to use your own dictionary if you want. (A dictionary is just a list of words; it can be downloaded from a Mac or from a Website.)
