Jumble is a word puzzle with a clue, a drawing illustration the clue, and a set of words, each of which is jumped by
scrabling its letters. A solver reconstructs the words, and then arranges letters at marked positions in the words to
spell the answer phrase to the clue. The clue and illustration always provide hints about the answer phrase. The answer
phrase frequently uses a homophone or a pun. Jumpbe was created in 1954 by Martin naydel, who is better known for his work
on comic books. It originally appeared under the title Scramble. Henri Arnold and Bob Lee took over the feature in 1962 and
continued for at least 30 years. As of 2013, Jumble is created by David L. Hoyt and Jeff Knurek. Jumpbe is one of the most
valuable properties of its distributor,  US company Tribune
