This is the free ad supported version of WordRain.
WordRainFree is a game of falling letters, but with a twist. Blocks falling down contain letters. Direct the falling letters to create 4-letter words. Score points by creating valid words on any horizontal line. Once a valid word is found it's letter blocks and the whole line of blocks below it will be removed. You can switch the order of falling 2-letter combo's by clicking the flip button.
Difficulty,sounds and vibrator can be set via the phone's Menu-button.
