Dabble HD, originally $1.99, is today's free app. This has been the FAOD before, but this is the HD version. This game is really addictive. You have a word pyramid made of 20 letters. The objective is to make 5 words from them as fast as possible to get the highest score possible. Here's the catch; you have to make a 2 letter, 3 letter, 4 letter, 5 letter and a 6 letter word.
