Bogcat

This is the Parker Brothers Boggle game with a twist. Instead of grinding through typing in a bunch of annoying little words and all the suffixes, the dictionary is instead limited to a particular category, like animals, colors, etc....
It is a lot more mentally challenging, as you must focus on two things at once. Also, the keyboard is disabled to prevent users from quickly typing items within the category (dog, cat, rat, lion, tiger, bear, etc...) in hopes they are in the puzzle. Instead, the letters must be selected to prove that you have indeed found the word.
To Unselect letters, select either the first or last letter clicked.
At the end of the round, words that only you found are in Green, words that you and others found are Black, words that others found and you missed are Blue, and words that no one found are Red.
Finally, at the end of each round, if you hover your cursor over a word, it will supply the definition.
