  • the main control circuit 7 checks a stop mode of the stopped reels 21, determines whether or not a predetermined combination is won, so as to determine a winning combination, and transmits an identifier enabling the identification of the determined winning combination as a winning command to the image control circuit 8.
  • step S601 the image control CPU 85 having received the winning command sets the identifier enabling the identification of the winning combination included in the received winning command as a winning combination identifier.
  • the winning combination identifier is set at the same value as that of the internal winning combination identifier.
  • step S602 the image control CPU 85 selects effect data (winning), referring to the effect data table, based on the effect identifier and the remaining effect game counter value set in the above-described game start processing.
  • step S603 the image control CPU 85 reduces the remaining effect game counter value by "1", and in step S604, the image control CPU 85 sets the gaming identifier at "0 (not played)".
  • an effect image and a specific image are selected according to a winning mode related to the internal winning combination identifier determined at the start of the game.
  • an effect image selected based on identifiers set in the above-described processing at the jump destination is buffered in the image buffer in step S106.
  • step S110 After the effect image visible to the player is switched in step S110, the buffered effect image in the image buffer is transmitted to the image control IC (VDP) 86 in step S111.
  • VDP image control IC
  • step S112 a specific image is transmitted to the VDP 86.
  • FIG. 22 is a flow diagram illustrating transmission processing of a specific image to the image control IC (VDP) 86.
  • step S701 the image control CPU 85 determines whether the gaming machine 1 is being played or not, based on the gaming identifier.
  • step S702 the image control CPU 85 determines whether a certain effect (e . g . , "WIN #A" ) is being provided or not, based on the effect identifier.
  • a certain effect e . g . , "WIN #A”
  • the image control CPU 85 when the gaming identifier is "0 (not played)" or the effect identifier is one of "1" to "6" (an effect other than "WIN #A"), the image control CPU 85 performs steps S712 to S714. That is, the image control CPU 85 transmits an overlay image 1 (for the transmissive display area 3a), an overlay image 2 (for the transmissive display area 3b) and an overlay image 3 (for the transmissive display area 3c), to the VDP 86.
  • the image control CPU 85 sequentially judges the reel rotation identifiers corresponding to the reels 21, so as to select a specific image corresponding to the rotating state of each reel 21, and to determine an arithmetic computation on an overlap portion overlapping the specific image over the effect image.
  • step S703 the image control CPU 85 determines whether the left reel rotation identifier is "1 (rotating)" or not.
  • step S705 the image control CPU 85 transmits the overlay image 1 to the VDP 86.
  • step S704 the image control CPU 85 transmits an add image 1 (for the transmissive display area 3a) to the VDP 86.
  • the image control CPU 85 determines whether the center reel rotation identifier and the right reel rotation identifier are "1 (rotating)" or not.
  • the image control CPU 85 transmits the overlay image 2 and the overlay image 3 to the VDP 86.
  • the image control CPU 85 transmits add images 2 and 3 to the VDP 86.
  • transmissive display areas 3a to 3c corresponding to the stopped reels 21 blue add images are displayed, and an addition processing on color information of each pixel is performed on an overlap portion overlapping a specific image over an effect image, so that the color information on the overlap portion are varied.
  • a display mode in a portion of an effect image displayed in the transmissive display areas 3a to 3c, that is, an overlap portion of the effect image over the reel display windows 2a can be varied. Therefore, it is possible to facilitate distinction between the display of symbols and the display of the effect image in the reel display windows 2a, and to provide a more visible display of the effect image.
  • the specific image 5a in blue (0, 0, 255) or the specific image 5b in white (255, 255, 255) can be selectively displayed according to the operations of the reels 21 displayed in the reel display windows 2a, so as to provide variation in winning mode display and to provide a more visible display in the reel display windows 2a.
  • the blue specific images 5a are displayed in an overlapping manner, and an overlap portion overlapping the specific image 5a over the effect image 4 is varied by an addition processing, so as to provide a clear contrast between the specific image 5a and the effect image 4, making the effect image 4 more visible.
  • the white specific image 5b is preferentially displayed, so as to make the reel 21 more visible, resulting in a more visible important display in a game and an effective attraction in a game.
  • the present invention is characterized by including a display device configured to display an effect image according to the progress of a game by a player, the display device including a winning mode display area capable of displaying a predetermined winning mode determined on the basis of the player's operation, and a display mode altering unit configured to alter a display mode in a portion of the effect image displayed in the winning mode display area.
  • the gaming machine 1 may be configured without the stop buttons 62 to 64 for stopping the reels 21.
  • the reels 21 are designed to be automatically stopped after an elapse of a predetermined period of time after the start of rotation.
  • the gaming machine 1 may be configured to include the function of the sub-control circuit in the main control circuit 7.
  • the present invention has been described with the embodiment in which the gaming machine of the invention is adapted for a slot machine, but the present invention is not limited thereto.
  • the present invention is also applicable to other gaming machines such as a pachinko machine equipped with a display device including a winning mode display area capable of displaying a winning mode, provided in such a manner as to cover the winning mode display area.
  • the present invention is also applicable to devices for displaying a virtual slot machine, pachinko machine or the like as described above on a television screen, such as arcade video game machines and home video game machines.
