  • the slot machine 10 B of the present embodiment does not have elements corresponding to the fluorescent tubes 78 a , 78 b for illuminating the reels 3 A to 3 C and the lamp holders 79 e to 79 h of the first embodiment.
  • the slot machine 10 B of the present embodiment does not have components corresponding to the stepping motors 45 A to 45 C for spinning the reels 3 A to 3 C and the motor drive circuit 120 of the first embodiment. Then, the jackpot bonus game on the central slot game area A 1 of the LCD panel 17 is executed under the control of the display controller 140 as the slot game on each of the other slot game areas A 2 to A 11 . Therefore, the center area of the liquid crystal unit 74 is controlled so that it is not in a permanent inactive state but in an active state according to displayed contents.
  • the slot machine 10 B of the present embodiment is configured in the same manner as that of the slot machine 10 of the first embodiment.
  • the difference between the slot machine 10 B of the present embodiment and the slot machine 10 of the first embodiment can be applied also to the slot machine 10 A of the second embodiment.
  • the slot game area A 1 corresponding to the “specific slot game area” in claims is arranged in the center of the lower display 16 , surrounded by the other slot game areas A 2 to A 11 .
  • the slot game area A 1 (the specific slot game area) may be disposed not on the lower display 16 but at another different position, independently from the other slot game areas A 2 to A 11 .
  • the slot game area A 1 (the specific slot game area) may be disposed on the upper display 33 .
  • the slot game areas A 2 to A 11 are disposed on the lower display 16 . It is possible to dispose the slot game area A 1 constituted by the mechanical reels 3 A to 3 C on the lower display 16 and the slot game areas A 2 to A 11 constituted by the LCD panel 17 on the upper display 33 .
  • the slot game execution processing on the slot game areas A 1 to A 11 is basically the same as the processing in the slot machines 10 , 10 A, and 10 B in the first to third embodiments.
  • the examples are shown, in which the slot games are executed in all of the slot game areas A 1 to A 11 regardless of activation. However, it may also be possible to execute the slot games only in the activated slot game areas A 1 to A 11 . Alternatively, a movie, which is looked like a slot game, may be played on each non-activated slot game area.
