Method of playing a slot machine with location dependent symbol award values
The present invention includes a variety of methods to calculate symbol award values based upon the location of one or more predetermined symbols in the symbol matrix. In a preferred embodiment, the award value for a symbol varies according to the row in which the symbol appears. In another embodiment, the award value for symbols varies according to the relative locations of the symbols to each other in the symbol matrix.
1. A method of operating a slot machine of the kind that displays a symbol matrix formed by at least one row intersecting a plurality of columns, a symbol location being defined at each row-column intersection, the rows and columns including a plurality of symbols, one symbol being displayed at each symbol location, the slot machine under control of a processor, the method comprising:
defining in the processor at least one symbol as an award symbol;
selecting in the processor, from among all symbol locations without regard to whether any symbol location has been selected for display of any symbol, at least one first-award symbol location and at least one second-award symbol location for the award symbol;
associating in the processor a first value with the first-award symbol location and a second value with the second-award symbol location, wherein the first value is different than the second value based on the location of the award symbol on the symbol matrix regardless of combinations with other symbols in the symbol matrix;
randomly rearranging in the processor the plurality of symbols;
displaying the rearranged symbols on a display of the slot machine; and
under control of the processor, issuing an award having the first value if an award symbol appears in a first-award symbol location without regard to any symbol appearing in any adjacent location and having the second value if an award symbol appears in a second-award symbol location without regard to any symbol appearing in any adjacent location.
2. A method of operating a slot machine of the kind that displays a symbol matrix formed by at least one row intersecting a plurality of columns, the rows and columns including a plurality of symbols, the slot machine under control of a processor, the method comprising:
defining in the processor at least one symbol as an award symbol;
randomly assigning in the processor award values to the rows and columns where the award symbol may be displayed, without regard to whether any symbol location has been selected for display of any symbol, and without regard to appearance of the award symbol in combination with other symbols in the symbol matrix, wherein the assigned award values differ from each other based on the column and row of each assigned award value;
randomly rearranging in the processor the plurality of symbols;
displaying on a display of the slot machine the rearranged symbols; and
under control of the processor, issuing an award for appearance of the award symbol anywhere in the symbol matrix, the award having a value determined by the assigned award value of the row and the column in which the award symbol appears, without regard to any symbol adjacent to the award symbol.
3. A method of operating a slot machine of the kind that displays a symbol matrix formed by at least one row intersecting a plurality of columns, the rows and columns including a plurality of symbols, the slot machine under control of a processor, the method comprising:
defining in the processor at least two symbols as award symbols;
randomly rearranging in the processor the plurality of symbols;
displaying on a display of the slot machine the rearranged symbols; and
under control of the processor, issuing an award for appearance of two award symbols anywhere in the matrix, the award having a value which changes based on the the locations of the award symbols within the symbol matrix, wherein the value is determined by measuring the relative distance between the two award symbols, without regard to any location of any other symbol, and without the award symbols appearing in combination with other symbols in the symbol matrix.
4. The method of claim 3 , in which the distance between the two award symbols is measured by the number of rows separating the two award symbols.
5. The method of claim 3 in which the distance between the two award symbols is measured by the number of columns separating the two award symbols.
6. A method of operating a slot machine of the kind that displays a symbol matrix formed by at least one row intersecting a plurality of columns, the rows and columns including a plurality of symbols, the slot machine under control of a processor, the method comprising:
defining in the processor at least two symbols as award symbols;
randomly rearranging in the processor the plurality of symbols;
displaying on a display of the slot machine the rearranged symbols; and
under control of the processor, issuing an award for appearance of two award symbols anywhere in the matrix, the award having a value which changes based on the the locations of the award symbols within the symbol matrix, wherein the value is determined by counting at least one of A) the number of rows separating the two award symbols, and B) the number of columns separating the two award symbols, without regard to any location of any other symbol, and without the award symbols appearing in combination with other symbols in the symbol matrix.
