From JAMDAT Mobile Canada (ULC):
Word Craft is a fast n' furious race against time and temperature! Spell as many words as possible using letters that get red hot when you formulate a word. Each word you craft disintegrates to reveal new letters -create even more new words to rack up mega points. But be ready to think fast because tiles also cool off slowly and eventually harden up completely. When all tiles are ice-bound, your grid freezes and its game over. Make sure to keep an eye on the temperature meter and turn up the heat on your game.
