Abstract

The present invention relates to an electronic gaming machine, in which after a game is executed by betting playing mediums such as tokens, the number of playing mediums to be paid is determined in response to the result of game. The electronic gaming machine includes a plurality of reels, and when the reels stop, one of plural symbols printed around each reel is stopped on a stop line. On the reels, a numerical and a non-numerical symbol are indicated together, and when the reels stop, an internal control unit judges the kind of symbols stopped on the stop line and the content of the numerical values. When the symbols on the stop line are all associated with the numerical values, the control unit substitutes the numerical values into a predetermined operational equation to execute the operation, and thereby determines the number of tokens to be paid in response to the operation result. The numerical values stopped on the stop line and the operation result are displayed and the operation process and operation result are disclosed to the player.

Claims

1. An electronic gaming machine, in which after a game has been executed by betting playing mediums, the number of playing mediums to be paid is determined in response to a result of the game, said electronic gaming machine comprising:

a plurality of movable bodies containing numerical symbols and non-numerical symbols together thereon;

drive means for separately driving and stopping the movable bodies such that one of the symbols on each movable body stops at a predetermined stop position;

symbol detecting means for detecting the types of symbols on the movable bodies stopped at the stop position and the numerical value of any numerical symbols of the movable bodies stopped at the stop position; and

operation means for substituting the detected numerical values into a predetermined operational equation and for performing an operation in response thereto to produce an operation result, when the symbols of the movable bodies detected by the symbol detecting means are all numerical symbols having numerical values, to thereby determine the number of playing mediums to be paid in response to the operation result.

2. An electronic gaming machine in accordance with claim 1, wherein said electronic gaming machine further includes

an operation display means for displaying an operational equation having a number of numerical substitution units corresponding to the number of movable bodies, with numerical displays being provided on the numerical substitution units;

and

display control means for controlling said operation display means to display corresponding numerical values on the numerical display means for symbols of the movable bodies detected by the symbol detecting means.

3. An electronic gaming machine according to claim 1, wherein there are three said movable bodies containing said numerical symbols and said non-numerical symbols together thereon.

4. An electronic gaming machine according to claim 1, wherein said movable bodies include different borders surrounding said numerical symbols, with said numerical and non-numerical symbols constituting a first type of symbol and said different borders constituting a second type of symbol.

5. An electronic gaming machine according to claim 4, wherein said operation means further assigns a mathematical factor to the operation result in response to said second types of symbols associated with the numerical symbols stopped at the stop position.

6. An electronic gaming machine according to claim 5, further including a fourth movable body containing different indicia thereon, said different indicia constituting a third type of symbol.

7. An electronic gaming machine according to claim 6, wherein said operation means further assigns an additional mathematical factor to the operation result in response to the third type of symbol associated with the numerical symbols stopped at the stop position.

8. An electronic gaming machine according to claim 1, wherein said operation means includes central processing means for performing said operation, ROM means for storing an operational program used by said central processing means and RAM means for providing a storage area for said operation result.
