Fill-in Quiz
The Fill-in Quiz is a word game: you read the clue and the answer is already there, but with some letters missing. You type only those, from the first empty box to the last, and confirm with OK: if the word is "core" and you see _ O _ E, you type C and then R. Time doesn't affect your grade, as long as you finish within 35 seconds. The Wildcard reveals more letters but costs three points; the Magic Wand reveals even more, with no penalty.
You can play some of the Fill-in quizzes right away as a guest; with a free account you unlock them all and save your scores and grades. Timing, grades and hints for every mode are in the quiz guide.
Subjects that suit Fill-in best
Letters to complete work best with names and words you know but can't quite spell out in a hurry: try the geography quiz, the science quiz and the animal quiz. If you'd rather find the word with no letters to help you, try the Guess quiz.
