QuickSpell is a beat-the-timer word game that tests your skills and patience.  Currently there is a bank of 571 words, but it will grow to nearly 16,000 words and definitions soon.  After each level you will see the definition of the word for that level.  There are as many levels as you can keep up with, but each new level increases the speed the timer depletes.  Don't tap the wrong button, or you'll find your time slipping away faster.  Be careful, be smart...  be quick!
