In Classic and Endurance modes, survive by spelling words with letters falling from the sky before the letters fill up the screen. In Race mode, think fast and spell as many words as you can before the clock runs out. In Puzzle mode, take your time and spell words using every last letter on the screen to win the game. Choose color themes, sound settings, and pick whether you prefer upper or lower case letters. There is a Gray color theme that works well for those that have a hard time seeing color.
