 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.

Referring to FIGS. 1 and 2, the first preferred embodiment of a gaming apparatus 1 of the present invention includes a machine body 10, a control system 2 disposed in the machine body 10, an input unit 3, and an output unit 4. The control system 2 includes a game processor 21, and a storage medium 22 and a memory device 23 that are coupled to the game processor 21. The input unit 3 includes a start button 31, a left select button 32, and a right select button 33 that are disposed on a surface of the machine body 10 and coupled to the game processor 21. The output unit 4 includes a display screen 40 mounted on a top portion of a front side of the machine body 10, and a display controller 41 coupled between the control system 2 and the display screen 40.

In other embodiments, the machine body 10 can be configured to satisfy different requirements, or can be designed for other gaming apparatuses. For example, the machine body 10 can be provided with a coin slot, other function buttons, a payout mechanism, a coin tray, etc., and details thereof will be omitted herein for the sake of brevity.

In this embodiment, the storage medium 22 of the control system 2 is a read-only memory (ROM) storing program instructions for playing an interactive slot game that includes a primary slot game and a bonus slot game. The memory device 23 of the control system 2 is a random-access memory (RAM) adapted for storing data and information generated during the primary slot game and the bonus slot game. When the program instructions are executed, the game processor 21 is operable to perform consecutive steps of a gaming method for playing the primary slot game and the bonus slot game. The following description is provided to describe the gaming method in detail.

Referring to FIGS. 2 and 3, when a player makes an appropriate act, such as dropping enough tokens, the game processor 21 is triggered to execute the program instructions stored in the storage medium 22, and one round of the primary slot game starts.

In step (S11), the game processor 21 is operable to allow the player to input a first start command through the start button 31. In response to the first start command from the start button 31, the game processor 21 controls the display controller 41 to enable the display screen 40 to display an animation image of rotating reels.

Then, in step (S12), the game processor 21 randomly generates a primary game symbol combination including a plurality of game symbols, and controls the display controller 41 to enable the display screen 40 to display the primary game symbol combination thereon. In this embodiment, the primary game symbol combination is in a form of, but not limited to, a 3×5 matrix having a plurality of game symbol positions, each of which corresponds to one of the game symbols in the game symbol combination.

In this embodiment, each round of the primary slot game provides the player with a first predetermined number of chances to input the first start command for rotating the reels to generate the primary game symbol combination, and the first predetermined number is stored in the memory device 23. Moreover, the game processor 21 is operable to subtract one from the first predetermined number stored in the memory device 23 in response to the first start command from the start button 31.

In step (S13), the game processor 21 is operable to determine whether the primary game symbol combination conforms with a primary winning condition. In this embodiment, the primary winning condition is that the game symbols in an upper payout line, a middle payout line or a lower payout line in the primary game symbol combination are the same symbol.

When the primary game symbol combination conforms with the primary winning condition, the game processor 21 is operable to grant the player an award instep (S14) and the current round of the primary slot game is completed. On the other hand, when the primary game symbol combination fails to conform with the primary winning condition, in step (S15), the game processor 21 is operable to further determine whether the primary game symbol combination conforms with a bonus condition for proceeding with the bonus slot game. In this embodiment, the bonus condition is that the primary game symbol combination includes a predefined number of specific same game symbols, or that the game symbols in each of the first column and the fifth column in the matrix of the primary game symbol combination are the same symbol.

The game processor 21 is operable to execute the relevant program instructions stored in the storage medium 22 for playing the bonus slot game when the determination made in step (S15) is affirmative, and the flow goes to step (S16) when otherwise. Instep (S16), the game processor 21 is operable to check whether the first predetermined number stored in the memory device 23 is equal to 0. When the first predetermined number is equal to 0, the current round of the primary slot game is completed, and the game processor 21 controls the display controller 41 to enable the display screen 40 to display an end image. Otherwise, the display screen 40 displays an image to notify the player to input the first start command for rotating the reels again, and the flow goes back to step (S11).

Referring to FIGS. 2 and 4, the game processor 21 executes the relevant program instructions for playing the bonus slot game when the primary game symbol combination conforms with the bonus condition. In this embodiment, the bonus slot game provides the player with a second predetermined number of chances to input a second start command for rotating the reels to generate another game symbol combination, and the second predetermined number is stored in the memory device 23.

In step (S21), the game processor 21 controls the display controller 41 to enable the display screen 40 to display a bonus game image as shown in FIG. 5. In the bonus slot game, the first and fifth columns in the matrix of the primary game symbol combination are excluded, and two monkeys holding rocks replace the first and fifth columns in the matrix. It should be noted that the appearance of the bonus game image is for illustrative purpose only, and should not be limited to the disclosure of this embodiment.

In step (S22), the game processor 21 is operable to check whether the second predetermined number stored in the memory device 23 is equal to 0. When the second predetermined number is equal to 0, the flow goes back to step (S16). Otherwise, the game processor 21 controls the display controller 41 to enable the display screen 40 to display an image to notify the player to input the second start command for rotating the reels, and the flow goes to step (S23).

In step (S23), the game processor 21 is operable to allow the player to input the second start command through the start button 31. In response to the second start command from the start button 31, the game processor 21 controls the display controller 41 to enable the display screen 40 to display the animation image of rotating reels. In the bonus slot game, only three reels in the middle are rotated. Moreover, the game processor 21 is operable to subtract one from the second predetermined number stored in the memory device 23 in response to the second start command from the start button 31.

Subsequently, in step (S24), the game processor 21 randomly generates the game symbol combination including a plurality of game symbols as shown in FIG. 6, and controls the display controller 41 to enable the display screen 40 to display the game symbol combination thereon. In the bonus slot game, the game symbol combination is in a form of a 3×3 matrix excluding the first and fifth columns in the matrix of the primary game symbol combination.

In step (S25), the game processor 21 is operable to determine whether the game symbol combination generated in step (S24) includes a changeable game symbol therein. In this embodiment, the game processor 21 is configured to check each of the upper, middle and lower payout lines for determining whether there is a changeable game symbol in any one of the payout lines of the game symbol combination. The changeable game symbol is one of the game symbols in the game symbol combination generated in step (S24) that differs from remaining same ones of the game symbols in the upper, middle or lower payout line of the game symbol combination. For instance, the game symbol combination shown in FIG. 6 includes a changeable game symbol “B” in the middle payout line. It should be noted that the definition of the changeable game symbol is not limited to this embodiment. For example, the changeable game symbol can be one of the game symbols that differs from remaining same ones in a vertical line or a diagonal line of the game symbol combination in other embodiments.

When the game symbol combination does not include a changeable game symbol therein, the flow goes back to step (S22). On the other hand, when it is determined that the game symbol combination includes a changeable game symbol therein, the flows goes to steps (S26) and (S27). In step (S26), the game processor 21 is operable to determine a corresponding position of the changeable game symbol in the game symbol combination, and to record the game symbol combination and the corresponding position in the memory device 23. For example, the changeable game symbol “B” in the game symbol combination shown in FIG. 6 is at the corresponding position (2,1), i.e., a left game symbol position in the middle payout line. Further, in step (S26), the game processor 21 is also operable to start a timer once presence of the changeable game symbol is determined.

In step (S27), the game processor 21 allows the player to manipulate the input unit 3 within a predetermined time limit to generate a response signal that indicates a player-selected position in the game symbol combination. When the game symbol combination shown in FIG. 6 is displayed on the display screen 40, the player has to identify the changeable game symbol “B” and to press the left select button 32 of the input unit 3 to generate the response signal for selecting the left game symbol position as the player-selected position within the predetermined time limit. Furthermore, the player has to press the right select button 33 when the player determines that the changeable game symbol is at a right game symbol position in one of the payout lines, and has to press both of the left select button 32 and the right select button 33 upon determining that the changeable game symbol is at a middle game symbol position in one of the payout lines. In other embodiments, the input unit 3 can further include a middle select button operable to generate the response signal for indicating the middle position, or a joystick can be used for replacing the left and right select buttons 32, 33. Alternatively, the input unit 3 can include a touch screen adapted to be pressed by the player to generate the response signal for indicating one of the game symbol positions as the player-selected position.

When the game processor 21 fails to receive the response signal from the input unit 3 within the predetermined time limit, the game processor 21 controls the display controller 41 to enable the display screen 40 to display a relevant image to notify the player of loss of the current chance in the bonus slot game in step (S28). Then, the flow goes back to step (S22). In the case of failure to receive the response signal, the relevant image is shown to notify the player that the time limit has expired.

In response to the response signal, in step (S29), the game processor 21 is operable to determine whether the player-selected position indicated by the response signal is the corresponding position of the changeable game symbol determined and stored in step (S26). The flow goes to step (S30) when the determination made in step (S29) is affirmative, and goes to step (S28) when otherwise. In such case that the player-selected position is not the corresponding position of the changeable game symbol, the relevant image shown in step (S28) is used for notifying the player of wrong identification of the changeable game symbol.

In step (S30), the game processor 21 is operable to randomly change the changeable game symbol, and controls the display controller 41 to enable the display screen 40 to display a game image of changing the changeable game symbol as shown in FIG. 7. In this embodiment, probability of changing the changeable game symbol to be the same as the remaining same ones of the game symbols in the payout line is enhanced compared to probability of getting said one of the game symbols when the game symbol combination is generated in step (S24). Referring to the game symbol combination shown in FIG. 6, the game symbols in the middle payout line will be the same symbol when the changeable game symbol “B” in the game symbol combination is changed to be the game symbol “A”. Thus, the probability of changing the changeable game symbol “B” to be the game symbol “A” is enhanced. For example, the probability of getting the game symbol “A” in step (S24) is 1/3, and the probability of changing the changeable game symbol “B” to be the game symbol “A” is enhanced to 2/3.

Subsequently, in step (S31), the game processor 21 is operable to determine whether a revised game symbol combination that includes the game symbol changed in step (S30) conforms with a predetermined winning condition. In this embodiment, the predetermined winning condition in the bonus slot game is similar to the primary winning condition in the primary slot game. When the revised game symbol combination conforms with the predetermined winning condition, the game processor 21 is operable to grant the player an award in step (S32), and the display screen 40 is controlled to display the game images of winning the slot game as shown in FIGS. 8 and 9. Then, the current round of the primary slot game is completed. When the revised game symbol combination fails to conform with the predetermined winning condition, the flow goes back to step (S22).

It should be noted that, when it is determined that the game symbol combination includes more than one changeable game symbol therein in step (S25), the game processor 21 is operable to compare the player-selected position indicated by the response signal with each of the corresponding positions of all the changeable game symbols. When the player-selected position is any one of the corresponding positions of all the changeable game symbols, the flow goes to step (S30).

Referring to FIGS. 2, 3 and 10, the second preferred embodiment of the gaming method for playing the interactive slot game of this invention is described in the following.

The gaming method of this embodiment is similar to the gaming method of the first preferred embodiment. First, the game processor 21 is operable to execute the program instructions stored in the storage medium 22 for playing the primary slot game. The game processor 21 is operable to execute the bonus slot game when it is determined that the primary game symbol combination generated in step (S12) conforms with the bonus condition in step (S15).

In this embodiment, the bonus slot game provides the player with only one chance to input the second start command for rotating the reels to generate the game symbol combination. Steps (S41), (S42) and (S43) are similar to steps (S21), (S23) and (S24) of the gaming method of the first preferred embodiment, respectively, and details thereof will be omitted herein for the sake of brevity.

In step (S44), the game processor 21 is operable to determine whether the game symbol combination generated instep (S43) includes a changeable game symbol therein. When the game symbol combination does not include a changeable game symbol therein, the flow goes to step (S51). On the other hand, when it is determined that the game symbol combination includes a changeable game symbol therein, the flows goes to steps (S45).

In step (S45), the game processor 21 is operable to determine a corresponding position of the changeable game symbol in the game symbol combination, and to record the game symbol combination and the corresponding position in the memory device 23.

In step (S46), the game processor 21 allows the player to manipulate the input unit 3 within a predetermined time limit to generate a response signal that indicates a player-selected position in the game symbol combination. When the game processor 21 fails to receive the response signal from the input unit 3 within the predetermined time limit, the current round of the bonus slot game is completed, and the flow goes back to step (S16).

In response to the response signal, in step (S47), the game processor 21 is operable to determine whether the player-selected position indicated by the response signal is the corresponding position of the changeable game symbol determined and stored in step (S45). The flow goes to step (S48) when the determination made in step (S47) is affirmative, and goes back to step (S16) when otherwise.

In step (S48), the game processor 21 is operable to randomly change the changeable game symbol, and controls the display controller 41 to enable the display screen 40 to display a game image of changing the changeable game symbol. Probability of changing the changeable game symbol to be the same as the remaining same ones of the game symbols in the payout line is enhanced compared to probability of getting said one of the game symbols when the game symbol combination is generated in step (S43).

Subsequently, in step (S49), the game processor 21 is operable to determine whether a revised game symbol combination that includes the game symbol changed in step (S48) conforms with a predetermined winning condition. When the revised game symbol combination conforms with the predetermined winning condition, the game processor 21 is operable to grant the player an award in step (S50), and the current round of the slot game is completed. On the other hand, when the revised game symbol combination fails to conform with the predetermined winning condition, the flow goes back to step (S16).

Since the relevant contents in steps (S46) to (S49) are similar those in steps (S27) to (S31) of the gaming method of the first preferred embodiment and have already been described, details thereof will be omitted herein for the sake of brevity.

In step (S51), the game processor 21 is operable to determine whether the game symbol combination generated in step (S43) includes a special game symbol therein. When it is determined that the game symbol combination includes the special game symbol therein, the game processor 21 is operable to give the player an option to manipulate the input unit 3 for generating a select signal in step (S52). Otherwise, the flow goes back to step (S16).

In this embodiment, the special game symbol is a game symbol which is not expected to appear in the game symbol combination, such as the game symbol “” in the game symbol combination shown in FIG. 11. The player has to identify presence of the special game symbol, and should not press the left and right select buttons 32, 33 of the input unit 3 when the special game symbol appears in the game symbol combination. When the game processor 21 receives the select signal from the input unit 3 in step (S52), the game processor 21 controls the display controller 41 to enable the display screen 40 to display corresponding game images as shown in FIGS. 12 and 13 in step (S53). Then, the current round of the bonus slot game is completed without granting the award to the player, and the flow goes back to step (S16). On the other hand, when the game processor 21 fails to receive the select signal from the input unit 3 within a predetermined time limit, the game processor 21 is operable to grant an auxiliary award to the player in step (S54) and complete the current round of the slot game.

In conclusion, the interactive slot game according to the present invention includes the primary slot game and the bonus slot game. In particular, the bonus slot game provides greater interaction with the player. Therefore, interest of the player in the interactive slot game is further enhanced.

While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments 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.
