WfW app for iPhone and iPad
WfW (Words from Words) is a simple game of logic, where you have to create new words using the letters from the main word given.
The more letters you use from the given word the more points you get. You can challenge your friends by selecting the same word and publish your results on Facebook.
Test yourself and see broad your own vocabulary is. This game is the cool way to kill some time on your way to work or uni and makes even a boring lecture more entertaining.
