PROBLEM TO BE SOLVED: To accurately find an actuation expected value variation width of a first kind special motor-driven generator by storing it by input of respective parameters of actuation and a probability in first/second states of a first kind game machine, and arithmetically operating, storing and displaying the actuation expected value variation width. SOLUTION: Parameters F2 and FH on actuation of a special pattern display device in a first state and a second state and parameters GL and GH on a special pattern, are inputted by an input device 4. A CPU 1 respectively stores these in corresponding storage areas 6a to 6d of a file 6. Next, (FH/FL)×(GH/GL) is arithmetically operated by searching out these parameters on the basis of an indication of starting operation processing so that the result is stored in a variation width storage file 7 and an operation result is displayed on a display device through a path 5. Then, an expected value variation width can be accurately found with simple constitution. |
