On the screen you will see a word with two missing letters. Your job is to figure out what letters you can use to make a valid English-language word. Type the letters, or click the corresponding letter on the alphabet display to put the letters in place.
In the first round there will be two words which can be created. For example, if you see "W I M _ _", you can create the words WIMPS and WIMPY. In the second round there will be three words to make from the given letters, in the third round there will be four words, and in the fourth round there will be five words.
The amount of time allotted per round gradually increases as you progress through the game.
Your score is based on a combination of speed and accuracy. Try to get as many words as possible, but also be careful to not enter invalid words.
Valid words are words which are found in the Enable2K word list.
