Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • This application claims priority of Taiwanese Application No. 094142075, filed on Nov. 30, 2005.
  • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a slot machine and a slot machine gaming method therefor, in which a matrix of cells generated in the slot machine gaming method by the slot machine is formed as a square m-by-m matrix, where (m) is an even number.
  • 2. Description of the Related Art
  • Referring to FIG. 1, a conventional slot machine utilizes a matrix of an odd number of cells for displaying indicia. Furthermore, dimensions of the matrix are typically unequal, that is, an m-by-n matrix is commonly utilized where (m) does not equal (n). As a result, problems are encountered with respect to pay lines used with such a matrix. In particular, with reference to FIG. 2, after all possible patterns for the pay lines are drawn through the matrix, a total number of times the different cells of the matrix are traversed by the pay lines is not the same for all the cells. This is outlined in Table 1.
    TABLE 1

  • It is evident from Table 1 that the total number of times the pay lines pass through the cells varies depending on the cell location in the matrix. For example, the pay lines pass through cell 8 in the center of the matrix (see FIG. 1) a total of seven times, while the pay lines pass through the remainder of the cells eight or nine times. Hence, the odds associated with the cells of the matrix are not the same. This makes it difficult to calculate overall win/loss probabilities for the machine, and makes difficult also the design of the layout of the pay lines.
  • SUMMARY OF THE INVENTION
  • The object of this invention is to provide a slot machine and a slot machine gaming method therefor, in which a matrix of cells generated in the slot machine gaming method by the slot machine is formed as a square m-by-m matrix, where (m) is an even number.

  • BRIEF DESCRIPTION OF THE DRAWINGS
  • Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
  • FIG. 1 is a schematic view of a 3×5 matrix utilized in a conventional slot machine;
  • FIG. 2 shows various pay lines applied to the 3×5 matrix of FIG. 1;

  • FIGS. 6 and 7 show various schematic views of pay lines applied to the 4×4 matrix of the present invention.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIG. 3, a slot machine according to a preferred embodiment of the present invention includes a game-processing unit 2, a display unit 3, and an input unit 4.
  • The game-processing unit 2 is connected to the display unit 3 and the input unit 4, and is configured to perform overall control of the slot machine, which includes performing consecutive steps of a slot machine gaming method of the present invention. The game-processing unit 2 generates an image of a matrix of cells on the display unit 3, and varies the display of indicia in each of the cells of the matrix during gaming. The input unit 4 allows for input by a user to start gaming, control betting parameters, etc.
  • The slot machine gaming method performed by the game-processing unit 2 will now be described with reference to FIG. 5.
  • In step 51, the game-processing unit 2 displays an image on the display unit 3 of a matrix of cells having (m) columns and (m) rows, where (m) is an even number. An example of such a matrix is shown in FIG. 4. In the matrix of FIG. 4, (m) is equal to four to thereby result in a square 4×4 matrix. However, the present invention is not limited in this respect, and it is important only that (m) be an even number as described above.
  • Next, in step 52, the game-processing unit 2 performs control to provide a plurality of pay lines 31 on the image of the matrix of cells as shown in FIG. 6. The pay lines 31 are selectively activated by the user through the input unit 4. Preferably, a total number of the pay lines 31 is a multiple of four. In the example shown in FIG. 6, a total of twenty-four of the pay lines 31 are provided on the image of the matrix.
  • To facilitate understanding of this embodiment, the pay lines 31 of FIG. 6 are divided into first through sixth groups of four of the pay lines 31 each. Each of the cells of the matrix is traversed once by one of the four pay lines 31 in the same group. Each of the pay lines 31 in each of the first through sixth groups passes from left to right (or from right to left) through four of the cells. Furthermore, for each of the groups of the pay lines 31, each of the cells is traversed only once by one of the lines. Therefore, each of the cells is traversed an equal total number of times (i.e., six times) by the twenty-four pay lines 31. This is outlined in the following Table 2.
    TABLE 2
    Number of times 24 pay lines traverse cells of
    4 × 4 matrix of the present invention

    16 1 1 1 1 1 1 6
  • Next, in step 53, after receiving user input with respect to the activated pay lines 31, the game-processing unit 2 performs control such that a plurality of indicia are consecutively displayed in each of the cells of the matrix for a predetermined time interval. After elapse of the predetermined time interval, the game-processing unit 2 performs control to maintain display of the indicia last appearing in the cells.
  • Subsequently, in step 54, it is determined if there is compliance with predetermined winning criteria based on a relation between the pay lines 31 activated by the user in step 52 and the indicia last appearing in the cells in step 53. If there is compliance with the predetermined winning criteria, the game-processing unit 2, in step 55, calculates and awards the user with points on the basis of the predetermined winning criteria.
  • As an example, points may be awarded to the user if the four cells through which an activated one of the It will be appreciated by those skilled in the art that the predetermined winning criteria may encompass a large variety of different conditions associated with the indicia displayed in the cells of the matrix and the activated pay lines 31.
  • Gaming is ended in step 56. Step 55 is skipped following step 54 if it was determined in step 54 that there is not compliance with the predetermined winning criteria.
  • In FIG. 6, although the pay lines 31 are shown extending between left and right sides of the matrix, the present invention is not limited in this respect, i.e., it is possible for the pay lines 3 to extend between top and bottom sides of the matrix, as shown in FIG. 7. The patterns of the pay lines 31 for each of the groups have been altered in FIG. 7 by rotating the corresponding patterns of FIG. 6 in a counterclockwise direction by 90 degrees. If desired, the groups may be selectively interchanged between FIG. 6 and FIG. 7, and still maintain equal odds for the cells.
  • Furthermore, although a 4×4 matrix of cells is used as an example in the present invention, other even-numbered square matrices may be employed, such as a 2×2 matrix or a 6×6 matrix. However, there may be drawbacks when using matrices with such different dimensions. For example, a very limited number of the pay lines 31 may be associated with a 2×2 matrix of cells. With a 6×6 matrix of cells, on the other hand, the indicia displayed in the cells may require shrinking to an excessively small size if a relatively small screen size is provided by the display unit 3.
  • In the present invention described above, a square m-by-m matrix in which (m) is an even number is generated in the slot machine gaming method by the slot machine. As a result, the pay lines 31 may be drawn such that the odds associated with each of the cells of the matrix are equal. Furthermore, the design of the layout of the pay lines 31 is simplified and maybe varied with relative ease.
  • While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
