Microsoft Wordament

Microsoft Wordament is a collection of three Microsoft games: Wordament, Crosswords and Word Twister.
At the beginning of each round, you will be presented with a board consisting of 16 tiles (4×4), each containing either a single (e.g. “A”) or double letter (e.g. Qu). Each letter is assigned a point value ranging from 1 – 10. Start searching the board for words in the puzzle. A word consists of any connected sequence of letters, in any direction, but you may not use a single tile more than once for a single word.
