PURPOSE:To make it possible to optionally control probabilities of hit or miss at the stoppage of pictures by changing range of value of random number or set values without changing number of combination of picture or that of combination of hit picture. CONSTITUTION:Indexes of hit pictures and miss pictures detected from a register of serial change r0 are renewed and stored randomly in a registers r0a and r0b, while present values of sequential occurrence random number RAN1 are held in a register R1 by the action of a switch SW1 so that picture display index i1 is renewed sequentially to start variation display of picture. Random number values of a register Ri and set value which is preset so as to be changed are compared to decide hit or miss by means of CPU32, whereby index of final display picture is selected from one of the registers r0a and r0b corresponding to the decision results to store it in a register r0c and present value of the picture display index i1 is reset by means of CPU32 so that the value of picture display index i1 which is sequentially renewed shows the value of r0c when variation is stopped. |
