In Wordy Blob the aim is to score points while keeping the size of the blob of word tiles to a minimum. Once it grows to fill the entire board the game's over. As new letter tiles appear you touch on an empty space around the edge of the blob hoping to create words of at least four letters and score points. Seven letter words score a bonus 50 points. Clearing the whole board scores you a bonus 20 points. The game will try to help you by giving you letters that form words with the letters already on the board. But as the game goes on, the help gradually disappears until you're on your own!
