Abstract
Abstract A toy for playing a number of different games having a housing containing a sound generating circuit and a number of removable game boards providing connections to the circuit. A laminate path affixed to the board and a probe provide means for connecting a resistor to the circuit and for carrying the value of resistor to change the frequency of the sound generated. In specific embodiments the path is broken so that a graphite path defined by a pencil may connect the parts of the circuit. The path is included in each of the games as a key to the play thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A toy for playing a plurality of games comprising a sound generating circuit, a game board, a resistor the value of which determines the frequency of the sound generated by the sound generating circuit, and means associated with the game board for connecting the resistor in the sound generating circuit including a pair of conductors affixed to the game board one of which is connected to the sound generating circuit, means for electrically connecting the conductors by placing a graphite connection between the conductors and means for connecting the second conductor to the sound generating circuit.
Claim 2
Dependent Claim
96 words
A toy for playing a plurality of games comprising a sound generating circuit, a game board, a resistor the value of which determines the frequency of the sound generated by the sound generating circuit, and means associated with the game board for connecting the resistor in the sound generating circuit including a pair of conductors affixed to the game board one of which is connected to the sound generating circuit, means for electrically connecting the conductors by placing a graphite connection between the conductors and means for connecting the second conductor to the sound generating circuit.
Claim 3
Dependent Claim
151 words
