Abstract
Abstract A slot machine has a game number counter which cumulatively counts the number of games played. That the number of games counted by the game number counter reaches a preset number or not is compared by a comparator, and if both numbers coincide, a coincidence signal is output from the comparator. The slot machine has also a winning number counter which cumulatively counts the number of winnings generated during the period until the number of games reaches the preset number. At the time the coincidence signal is obtained, the number of winnings cumulatively counted in the winning number counter is compared with a standard number of winnings. As a result of the comparison, if the number of winnings in the winning number counter is larger than the standard number of winnings, the following game is set difficult to get a winning, and in the contrary case to the above, control means is actuated for controlling a shift of symbols onto a winning line.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A slot machine of a type that the presence or absence of a win is judged for each game based upon a combination of symbols stopped on a winning line, characterised by: means for cumulatively storing the number of games played; means for cumulatively storing the number of winnings every time a game is played and a win is generated; comparison means for comparing said stored number of wins with a preset standard number of wins every time said stored number of games reach a predetermined number; and control means for controlling the stop positions of said symbols on said winning line in such a manner that when said comparison means detects that said stored number of winnings is larger than said standard number of wins a win is harder to get, and when said comparison means detects that said stored number of win.s is smaller than said standard number of wins, a win is easier to get.
Claim 2
Dependent Claim
158 words
A slot machine of a type that the presence or absence of a win is judged for each game based upon a combination of symbols stopped on a winning line, characterised by: means for cumulatively storing the number of games played; means for cumulatively storing the number of winnings every time a game is played and a win is generated; comparison means for comparing said stored number of wins with a preset standard number of wins every time said stored number of games reach a predetermined number; and control means for controlling the stop positions of said symbols on said winning line in such a manner that when said comparison means detects that said stored number of winnings is larger than said standard number of wins a win is harder to get, and when said comparison means detects that said stored number of win.s is smaller than said standard number of wins, a win is easier to get.
Claim 3
Dependent Claim
24 words
An apparatus according to claim 1, wherein said symbols are disposed on peripheries of a plurality of reels driven into rotation by stepping motors.
Claim 4
Dependent Claim

An apparatus according to claim 2, wherein said control means controls to stop said stepping motor.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
192 words
A slot machine of a type that the presence or absence of a win is judged at each game based upon a combination of symbols stopped on a winning line, characterised by: a game number setting section for storing a preset number of games; a game number counter for storing cumulatively the number of games played; a winning number setting section for storing a standard number of wins set in accordance with said preset number of games; a winning number counter for cumulatively storing the number of wins generated while games are played as many times as said preset number of games; first comparison means for outputting a coincidence signal by detecting that the number of games cumulatively counted by said game number counter reaches said preset number of games; second comparison means for comparing upon reception of said coincidence signal said standard number of wins with the number of wins cumulatively counted by said winning number counter and outputting a signal in correspondence with the comparison result; and control means for adjusting the stop positions of symbols on said winning line in response to said signal from said second comparison means.
Claim 7
Dependent Claim
192 words
A slot machine of a type that the presence or absence of a win is judged at each game based upon a combination of symbols stopped on a winning line, characterised by: a game number setting section for storing a preset number of games; a game number counter for storing cumulatively the number of games played; a winning number setting section for storing a standard number of wins set in accordance with said preset number of games; a winning number counter for cumulatively storing the number of wins generated while games are played as many times as said preset number of games; first comparison means for outputting a coincidence signal by detecting that the number of games cumulatively counted by said game number counter reaches said preset number of games; second comparison means for comparing upon reception of said coincidence signal said standard number of wins with the number of wins cumulatively counted by said winning number counter and outputting a signal in correspondence with the comparison result; and control means for adjusting the stop positions of symbols on said winning line in response to said signal from said second comparison means.
