Killer Word is a deadly dictionary app which finds the word you need to win at word games like Letterpress. 

Can't think of a word with a Q but no U? No problem - here are 75 of them. Need a word with K, V, M & H to finish the game? No problem - it knows 9 obscure words that match. 

It will find all words that contain certain letters, e.g. all words that contain Q,W and P in any order (PASQUEFLOWER and PASQUEFLOWERS, a pretty violet colored plant).
It can exclude words based on letters, so you can do things like instantly find all words with a Q but no U.
New in version 2.0, there is a better way to exclude the words you don't want : you can type in the 5 by 5 letter board, which lets the engine find you only words possible with those 25 letters.

Even though the app has a dictionary of hundreds of thousands of words, our advanced search technology finds the right words instantly. It actually gets faster the harder you make the search.
Now supports multiple windows for multiple games.
