the author of this app says:
SwipeWord is a game with letters. The aim is to compose words of three,
four, five, six, seven or eight letters by swiping over the letters
presented by the game. If the word exists in the internal dictionary,
the player earns points and the letters in the game are replaced by new
letters. The game ends after thirty correct words.
- Requires iOS 4.3 or later.
