Abstract
Abstract An instructional and amusement device is disclosed which, in the preferred embodiment, is in the form of a book of several pages edgewise interconnected to allow the successive turning of pages in a sequential manner. Each page includes a path having a beginning on the page, having a convoluted traversal of the page, and having an end surrounding an aperture in the page. An object having significant magnetic properties is placed at the beginning of the path, and a magnet is placed under the book-like device to thus allow the object to be moved over the path under magnetic attraction between the magnet and the object under the control of a user until the object drops into an aperture in the page and onto the next page. The then exposed page is removed and the process is repeated upon the next page.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A book-like instructional and amusement device comprising, in combination: an object formed of a material having significant magnetic properties; a plurality of interrelated sheets with each sheet having a top surface having printing thereon and a bottom surface and with each sheet having at least one aperture defined therethrough; and a magnet of sufficient strength to magnetically attract the object through the plurality of sheets and of a size which can be manipulated under the bottom surface of the sheets by the hand of a user for allowing the object to be moved over the first surface of the sheets under magnetic attraction between the magnet and the object under the control of the user until the object drops into the aperture in an exposed sheet to the surface of the next sheet to thereby position the object on the sheet of the interrelated sheets next in sequence to the exposed sheet and allow the removal of The previously exposed sheet to expose the next sheet.
Claim 2
Dependent Claim
166 words
A book-like instructional and amusement device comprising, in combination: an object formed of a material having significant magnetic properties; a plurality of interrelated sheets with each sheet having a top surface having printing thereon and a bottom surface and with each sheet having at least one aperture defined therethrough; and a magnet of sufficient strength to magnetically attract the object through the plurality of sheets and of a size which can be manipulated under the bottom surface of the sheets by the hand of a user for allowing the object to be moved over the first surface of the sheets under magnetic attraction between the magnet and the object under the control of the user until the object drops into the aperture in an exposed sheet to the surface of the next sheet to thereby position the object on the sheet of the interrelated sheets next in sequence to the exposed sheet and allow the removal of The previously exposed sheet to expose the next sheet.
Claim 3
Dependent Claim
57 words
The device of claim 1, wherein the sheets are in the form of pages of a book having a cover and a plurality of pages edgewise interconnected to allow the successive turning of pages in a sequential manner and wherein at least one aperture on each page is coordinated with the printing on the next succeeding page.
Claim 4
Dependent Claim
49 words
The device of claim 2, wherein each page after the first includes a designated path printed thereon over which the object is intended to be moved, the path extending from a starting position adjacent the aperture of a previous page and extending to the aperture on the exposed page.
Claim 5
Dependent Claim
23 words
The device of claim 3, wherein the path is in a form of a printed boundary of sufficient width to accommodate the object.
Claim 6
Dependent Claim
64 words
The device of claim 4, wherein each page includes at least two apertures coordinated with the path on the next succeeding page in a manner to allow a favored and nonfavored response to be indicated by the position taken by the object dropping through a particular aperture and exposed upon the path of the next succeeding page by the removal of the previous page.
Claim 7
Dependent Claim
31 words
The device of claim 5, including a multi-choiced path and including symbols coordinated with the path to designate a direction to be taken at each point of choice on the path.
Claim 8
Dependent Claim
48 words
The device of claim 1, wherein each sheet after the first includes a designated path printed thereon over which the object is intended to be moved, the path extending from a starting position adjacent the aperture of a previous sheet and extending to the aperture on the sheet.
Claim 9
Dependent Claim
23 words
The device of claim 7, wherein the path is in a form of a printed boundary of sufficient width to accommodate the object.
Claim 10
Dependent Claim
64 words
The device of claim 1, wherein each sheet includes at least two apertures coordinated with the path on the next succeeding sheet in a manner to allow a favored and nonfavored response to be indicated by the position taken by the object dropping through a particular aperture and exposed upon the path of the next succeeding sheet by the removal of the previous sheet.
Claim 11
Dependent Claim
31 words
The device of claim 1, including a multi-choiced path and including symbols coordinated with the path to designate a direction to be taken at each point of choice on the path.
Claim 12
Dependent Claim
22 words
The device of claim 1, including a path in the form of a printed boundary of sufficient width to accommodate the object.
