Cl. 273-157 3 Claims ABSTRACT 0F THE DISCLUSURE An amusement device having 350 irregular shaped pieces which, when tted together, will form a rectangle, no two pieces of the devices being alike. All pieces are identical in color on lboth sides and a letter of the alphabet on the pieces is invisible to the eye and will spell out words when a chemical in liquid form is applied to the face of the pieces. The letters forming the words will become visible to the eye.

This invention relates to what is known as jig-saw puzzles and more particularly to a game of cut pieces which when put together properly will form a rectangle.

It is therefore the main purpose of this invention to provide a game which will be amusing while providing recreation for the players.

Another object of this invention is to provide a game which will have a plurality of cut flat pieces which will be identical in color on both sides and are cut in such a manner that it is impossible to know which is the correct side.

Another object of this invention is to provide a game in which the cut pieces of irregular shape will have an invisible letter which when the pieces are placed correctly together will forrn a word, the word being visible to the eye only after applying a chemical in liquid form to the face ofthe pieces.

Other objects of this invention are to provide a game which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification taken in connection with the attached drawing wherein:


The ligure is the sole view of the invention,

According to this invention, a game 10 is provided with a plurality of irregular shaped flat cut pieces, each of the pieces 11 -being of the same color on both sides. When the pieces 11 are correctly placed together, alphabetical characters 12 will produce a word, the Word being visible after applying a liquid chemical to the pieces 11.

In use, after the contestant puts the pieces 11 together with the letters Spelling the word correctly, all letters on one side, in numerical order, whether horizontal or vertical, that contestant wins whatever the word is. Typical spelled out words would be Cadillac, Ford, million or other suitable words. When the pieces 11 are in place, the contestant then applies the liquid chemical on the face of the pieces and then the alphabetical characters 12 will become visible to the eye.

What I now claim is:

1. A puzzle game, comprising in combination, a plurality of flat, disassociated pieces having irregularly cut mating edges whereby the pieces can be assembled in intertting relationship, a plurality of said pieces having invisible characters on one of the surfaces thereof and chemical means to -make the alphabetical ycharacters visible to the eye.
