  Next, with reference to FIG.2 and FIG.3, the structure of the special symbol display apparatus 8 and the screen displayed here are demonstrated. FIG. 2 is a front view of the special symbol display device 8, and FIG. 3 is a perspective view of a polyhedron display screen 28 provided in the special symbol display device 8. In the present embodiment, as an example of the symbol variation display displayed on each surface 28a to 28c of the polyhedron display screen 28 of the special symbol display device 8, the symbols are displayed by scrolling from top to bottom or from bottom to top. A description will be given by taking an example of a variable display of symbols.

  As shown in FIGS. 2 and 3, the polyhedron display screen 28 is composed of a polyhedron having three surfaces of a first surface 28a, a second surface 28b, and a third surface 28c, which are substantially rectangular surfaces. A base 28d is provided on the rear side of the three surfaces 28a, 28b, and 3c, and a drive shaft 90a of the direction changing motor 90 is connected to the end of the base 28d. Therefore, the polyhedron display screen 28 can be rotated in a plane perpendicular to the game board 2 and horizontal to the ground by the driving force of the direction changing motor 90.

  The first surface 28a of the polyhedral display screen 28 is provided with an electroluminescence display EL1, the second surface 28b is provided with an electroluminescence display EL2, and the third surface 28c is provided with an electroluminescence display EL3. ing. As is well known, this electroluminescence display uses a substance that emits light when a voltage is applied, and uses an inorganic electroluminescence display (inorganic EL display) that uses inorganic substances such as zinc sulfide and organic substances such as diamines. There are two types of organic electroluminescence displays (organic EL displays). These can obtain high luminance with low power, are excellent in terms of visibility, response speed, life and power consumption, and can be made thin like a liquid crystal display. It is also possible to bend along the semi-cylindrical side surface or the cylindrical side surface.

The symbol display portions are arranged in a horizontal row. In the special symbol display portions L1 to L3, symbols to be described later are variably displayed so as to scroll from top to bottom, and background symbols, characters, messages, and the like are also displayed on the electroluminescence displays EL1 to EL3. It has become so.

  The symbols displayed on the special symbol display portions L1 to L3 of the electroluminescence displays EL1 to EL3 are normally vertically scrolled (scrolling from the top to the bottom), respectively, so that the special symbol display portion L1 and the special symbol display are displayed. It stops in the order of the part L2, the special symbol display part L3, that is, the left symbol, the right symbol, and the middle symbol. In addition, the arrangement | positioning of this special symbol display part L1-L3, the order to stop display, etc. can be changed arbitrarily. The polyhedron display screen 28 does not always display special symbols on the special symbol display portions L1 to L3, and can display moving images, messages, and the like instead of these displays. The special symbol display device 8 includes a symbol display substrate 44 shown in FIG.

  In addition, as the symbols displayed on the special symbol display portions L1 to L3 of each of the electroluminescence displays EL1 to EL3, in the example of the present embodiment, “0” and “1” are examples of numerical symbol patterns. , “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, and a game ball at the start winning opening 15 or the starting winning opening 17 Are won and the jackpot is determined, these ten kinds of symbols are displayed in this order in principle. In the case of a big hit, three special symbols displayed in one horizontal row are aligned with the same number or character (for example, three such as “7”, “7”, “7”). In any case, the electroluminescent displays EL1 to EL3 having the jackpot symbol are rotated by the direction changing motor 90 so as to be in the center of the special symbol display device 8, and the player is notified of the jackpot. Then, a special gaming state is generated in which the grand prize winning opening 16 is opened, and when the game ball wins a V zone (not shown) provided in the big winning prize opening 16, the special winning prize opening 16 is opened again. It is repeated up to a predetermined number of times (for example, 15 times, 16 times, etc.). Further, as other design patterns, Chinese numerals, numbers written on shogi, numbers written on mahjong tiles, etc. may be used.

  Of the 10 symbols, “1”, “3”, “5”, “7”, and “9” are set as probability variation symbols (hereinafter referred to as “specific symbols”), and any of these symbols is selected. When the symbols are aligned in the same horizontal row, the probability change is entered, and the advantage is changed to increase the probability of drawing the next jackpot as the advantageous state (specific game state). As an example, the probability of jackpot is 1/315 in the normal state (low probability state), and 1/63 in the probability fluctuation state (high probability state or advantageous state). It is not limited. “0”, “2”, “4”, “6”, “8” are non-probability fluctuation symbols (hereinafter referred to as “non-specific symbols”), and the probability of winning a jackpot after that is normal. It becomes.
