## Abstract

An electronic logic game comprising a device for simulating a balance scale in its balanced state or either of its unbalanced states, a plurality of simulated playing pieces one of which is simulated to be heavier or lighter than the others and selected ones of which may be symbolically placed on said simulated balance scale, and a device coupled to said simulated balance scale for detecting the presence or absence of the simulated heavier or lighter playing piece and simulating the scale to be balanced or unbalanced in a predetermined direction according to the presence or absence of the piece whereby the heavier or lighter piece may be logically discovered in a predetermined number of electronic scale balance or unbalance representations.

## Claims

### Claim 1

An electronic logic game comprising:
a. a simulated electronic balance scale,
b. a plurality of units to be symbolically weighed, one of which units differs from the others electronically by including a first magnet to represent said unit being lighter than the other units or first and second magnets to represent said unit being heavier than the other units and selected ones of which units may be symbolically positioned on said simulated balance scale,
c. means associated with said simulated balance scale for detecting said different unit when symbolically positioned on said simulated balance scale, and
d. circuit means coupled to said detecting means for representing said scale to be balanced or unbalanced in a predetermined direction according to said state of said different unit whereby said different unit may be logically discovered in a predetermined number of said electronic scale balance or unbalance representations.

### Claim 2 (depends on 1)

An electronic game as in claim 1 wherein said simulated electronic balance scale comprises:
a. a right and left side of said scale, and
b. at least one indicator representing said scale tipped to the left, at least one indicator representing said scale tipped to the right, and at least one indicator representing said scale to be balanced.

### Claim 3 (depends on 2)

An electronic game as in claim 2 wherein said indicators are lights.

### Claim 4 (depends on 3)

An electronic game as in claim 3 wherein said detecting means comprises:
(a) a plurality of representations of individual areas, each of which is to receive one of said units, and
(b) first and second magnetic switches in each of said areas for detecting the presence of said first and second magnets and producing corresponding first and second signals.

### Claim 5 (depends on 4)

An electronic game as in claim 4 wherein said circuit means comprises:
(a) a first logic circuit coupled to said magnetic switches and said lights for energizing said light on the opposite side of said simulated balance scale than the side on which said unit with one magnet is positioned to simulate that said opposite side of said scale is heavy,
(b) a second logic circuit coupled to said magnetic switches and said lights for energizing said light on the same side of said simulated balance scale as that side on which said unit with both first and second magnets is positioned to simulate that said same side of said scale is heavy, and
(c) a third logic circuit coupled to said magnetic switches and said lights for energizing said light representing a balanced scale when there is no unit positioned on either side of said simulated balance scale which has either said first or said first and second magnets.

### Claim 6 (depends on 5)

An electronic game as in claim 5 wherein said magnetic switches are Hall effect devices.

### Claim 7 (depends on 6)

An electronic gas as in claim 6 further including a specific number to identify each of said units.

### Claim 8

A logic game including a simulated scale and units to be weighed comprising:
a. a pictorial representation of a balance scale,
b. means associated with said pictorial representation for indicating visually whether said scale is balanced or unbalanced and, if unbalanced, the direction of said unbalance to the right or left,
c. means for simulating one of said units to be heavier or lighter in weight than the remainder of said units, said simulating means including a first magnet to represent said unit being lighter than the other units or first and second magnets to represent said unit being heavier than the other units, and
d. electronic means coupled to said visual indicating means and said weight simulating means for causing the appropriate visual indicating means to be energized when any desired combination of said units are placed on said simulated balance scale whereby said one heavier or lighter unit may be detected by weighing a particular combination of said units a predetermined number of times.
