Разработчик приложения TWL Word Lookup - Tournament Word List: Travel Guides
Official Tournament and Club Word List or Tournament Word List, referred to as OTaCWL, OWL, or TWL, is the official word authority for tournament Scra-bble in the USA, Canada and Thailand. It is based on the Official Scra-bble Players Dictionary (OSPD) with modifications to make it more suitable for tournament play.
With this app, you can lookup to see if a word is spelt correctly, rather than using a dictionary. The advantage is that you do not get to look at other words when using a dictionary.
