Abstract

Electronic slot machine with a symbol display device which displays symbols which are arranged in rows and columns and which have at least one specially identified winning symbol which replaces or supplements a missing symbol which is necessary for a winning symbol combination.

Description

  • The invention relates to an electronic slot machine as claimed in the preamble of [0001] claim 1.
  • The journal Muenzautomat 4/1984, page 12, discloses a coin-operated electronic slot machine with a symbol game means composed of three reels located next to one another. When the reels stop the winning symbol combination is displayed in a viewing window. When three identical winning symbols are displayed, the prize assigned to them is awarded. Instead of one of these three symbols which are included in the winning combination a specially identified replacement symbol, a joker, can also be used. [0002]
  • It is however a disadvantage that this specially identified winning symbol is located one time only on the middle reel of the three reels. [0003]
  • The object of the invention is to develop a generic electronic slot machine such that a winning value can also be assigned even to an incomplete winning symbol combination. [0004]
  • This object is achieved by the characterizing features of [0005] claim 1.
  • Other features which form the invention can be taken from the dependent claims. [0006]
  • The electronic slot machine as claimed in the invention has the advantage that the varied use of a joker which completes the winning combination increases the entertainment value on the electronic slot machine. Since at the same time there are several different possible applications of the joker, the playing pleasure is especially high with long-lasting encouragement to use the electronic slot machine. [0007]
  • One embodiment as claimed in the invention is explained using the drawing. [0008]
  • FIG. 1 shows the front of a coin-operated entertainment machine.[0009]
  • The coin-operated electronic slot machine which is labeled [0010] 1 in FIG. 1 comprises a front side 2 with a viewing window 3 behind which there is a display device for display of symbols. The display device preferably consists of a TV monitor. The TV monitor displays five reels, located next to one another, with winning symbols. Three winning symbols at a time are displayed simultaneously by each stopped reel. Underneath the display device there is a control panel 4. On the control panel 4 there is a plurality of operational controls 5. Adjacent to the operational controls there is a coin acceptance opening 6. There is a coin removal trough 7 underneath the control panel 4.
  • The coin-operated [0011] electronic slot machine 1 comprises a control unit which is not shown, with a microcomputer. The control unit controls of the order of events in the electronic slot machine 1. If a balance meter has a play, the control unit causes a symbol combination, which is to be displayed, to be determined by a pseudorandom generator. The displayed reels with the TV monitor are caused to spin and are stopped such that predetermined symbol combinations are displayed. The symbols of the reels are displayed in a matrix form in the display device. The matrix comprises five columns and three rows. A total of nine win lines are evaluated. On each win line it is checked how often the same symbol is displayed. For a display of the same symbol five times, the highest winning value for this symbol is awarded. For display of three or four of the same symbols, a lower winning value is awarded. Furthermore, each reel comprises a specially identified symbol. The specially identified symbol has the function of a joker and replaces any displayed symbol for the required winning symbol. There are 32 symbols on each virtual reel. One or more of the winning symbols on each virtual reel are made as the specially identified winning symbol (joker). When displayed in the viewing window 3 of the stopped reel, the specially identified winning symbol causes all winning symbols adjoining to the left and/or right of it in a horizontally running win line to be replaced for the outer left or right displayed winning symbol and thus a win line with up to five winning symbols to be formed. The specially identified winning symbol is in the fourth display position from left to right and in the first display position.
  • On a coin-operated [0012] electronic slot machine 1 the control unit spins the virtual reels and stops them in predetermined positions. In the viewing window 3 of the coin-operated electronic slot machine 1 a winning symbol matrix consisting of three lines and five columns appears to the user. When a specially identified winning symbol is displayed, a joker, for example on the third reel in the second line, the bordering symbols are recognized a joker symbols in the evaluation of winning.

  • The win recognition program now detects the symbol arrangement for each of the nine win lines and compares it to the winning pattern. If several win lines have a winning combination, the highest prize is warded and it is credited in the balance storage of the control unit. [0013]
    Figure US20020068623A1-20020606-C00002
  • In another embodiment as claimed in the invention, when the specially identified winning symbol is displayed, not as before do all bordering symbols become the joker symbol, but a symbol combination, for example in the second line, is displayed in the display on the stopped virtual reels, and the right-hand, fifth reel in the second row shows a specially identified winning symbol, a joker, then the winning symbols located to the left of the specially identified winning symbol are treated as if the winning symbol of the 1st reel in the second row is displayed and according to the control unit-side winning pattern the winning value of five identical symbols located next to one another is awarded according to the winning pattern. [0014]
    Figure US20020068623A1-20020606-C00003
  • According to another embodiment as claimed in the invention, when the winning symbols are displayed by the stopped virtual reels, upon display of a specially identified symbol on the third, the middle, reel, displayed in the third line, and when an identical winning symbol is displayed by the first and the fifth reel each in the first line, the symbols located in the diagonals on the second and fourth reel in the second line are evaluated in the win line evaluation as if at this position the winning symbols are displayed which are displayed by the first and the fifth reels in the first line. [0015]
    Figure US20020068623A1-20020606-C00004
  • There is further evaluation and winning value determination as claimed in the invention when, of the displayed winning symbols, there is one symbol on the first reel in the first line, there is the specially identified winning symbol on the third reel in the first line and on the fifth reel in the third line there is a symbol identical to the first reel, first line. By using the specially identified winning symbol in the win line evaluation the winning symbols located to the specially identified symbol become the winning symbols which correspond to those on the first reel in the first line or on the fifth reel in the third line. The winning value of the five identical winning symbols is determined according to the winning pattern. [0016]
    Figure US20020068623A1-20020606-C00005
  • In a development as claimed in the invention for the coin-[0017] electronic slot machine 1 as claimed in the invention, when the specially identified symbol is displayed with the display device, it is determined pseudorandomly in which other display fields of the display matrix the displayed winning symbols are exchanged for the specially identified winning symbols.
    Figure US20020068623A1-20020606-C00006
  • If a specially identified winning symbol is displayed by the virtual reels on the second reel in the middle position, it is subsequently determined pseudorandomly how many other specially identified winning symbols are displayed and which position they are to occupy in the display field. When the winning value is subsequently determined, for example a specially identified winning symbol on the fourth reel in the first line and on the fifth reel in this third line will be displayed. In the subsequent evaluation of the displayed winning combination the special symbols are taken into account according to the winning pattern. Instead of pseudorandom selection of the number and position of the other specially identified symbols, symbols can be replaced by higher-value symbols, if they have already been identified as such beforehand. In addition to the specially identified symbols on the virtual reels there are symbols which assume the same function of the specially identified symbols to the extent that, of the displayed symbol combinations, there is at least one symbol as the specially identified winning symbol.
