A gaming machine uses a time-based method for generating game results having nonuniform probability. The gaming machine employs an addressable memory in cooperation with a counter and a clock. The clock generates a very fast series of pulses, and includes a digital-to-analog converter. The counter holds a number representing one of the possible reel stop positions and counts the clock\s pulses, so that with each pulse, the value of the counter advances by one. To vary the odds that a particular reel stop position will be selected, the clock\s pulses do not come at even intervals. Rather, the clock is responsive to a digital input signal to control how long it will allow a particular number to remain in the counter before the next clock pulse. The binary numbers which are used to control the clock are stored in memory. The memory accepts as input the current value of the counter. Thus, when the counter is incremented, the memory provides the binary number associated with the new counter value. By selecting appropriate binary numbers for each possible counter value, the relative amounts of time which the counter holds each value (and, therefore, the probability of selection) can be varied.
A gaming machine, comprising: a clock having a binary input and generating a periodic timing signal, wherein the frequency of the timing signal depends on the value of the binary input; a counter having an input coupled to the periodic timing signal, and an output which increments in accordance with
A gaming machine, comprising: a clock having a binary input and generating a periodic timing signal, wherein the frequency of the timing signal depends on the value of the binary input; a counter having an input coupled to the periodic timing signal, and an output which increments in accordance with the frequency of the timing signal; addressable memory capable of generating as output one of a plurality of preprogrammed binary values in response to particular values of counter outputs, wherein the memory\s output is coupled to the clock\s binary input; asynchronous means for periodically selecting the counter\s output as a game result, said asynchronous means being time independent of said clock; and display means for displaying the game result represented by the selected counter output.
