  According to such a configuration, it is possible to obtain a game program for causing a computer system to function as the game system in the first main aspect described above.

  ADVANTAGE OF THE INVENTION According to this invention, it is a game for electronic game machines, Comprising: Even if a rule is simple, the novel game which can be enjoyed according to a player's skill can be obtained.

Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of an electronic game machine according to an embodiment of the present invention, and FIG. 2 is a block diagram showing an internal configuration of the electronic game machine. The game machine 1 is a rechargeable portable game machine, and is configured such that the ends of the rectangular main housing 2 and sub-housing 3 are pivotally supported so that they can be folded. In the center, a main display 4a such as an LCD (Liquid Crystal Display) and a sub display 4b are mounted on the faces facing each other when folded. Each of the surfaces of the two displays 4a and 4b is composed of liquid crystal touch panels 6a and 6b for detecting a position touched by the player with a touch pen (stylus pen) 5 or a finger, whereby the displays 4a and 4b have an input function. Also serves as an output function.

  A slot 8 into which a recording medium (game cartridge) 7 storing game data including a game program and a game character to be described later is provided on the side surface on the front side of the main housing 2. A connector 23 (see FIG. 2) that is connected to the output terminal at the tip of the game cartridge 7 is provided at the back of the slot 8 (not shown). A large number of sound release holes 10 for the speaker 9 are formed on the left and right sides of the sub display 4 b of the sub housing 3. In addition, a switch group 11 such as a power switch and a cross key is disposed on the left and right of the main display 4a.

  In such a configuration, when the player inserts the game cartridge 7 into the slot 8 and turns on the power switch, the game program and game data in the game cartridge 7 are loaded into a RAM 27 (to be described later) of the game machine 1 and the game play is performed. It becomes possible.

  In the game machine 1, a CPU core 21 as a control device is mounted on an electronic circuit board 20 indicated by a one-dot chain line in FIG. The CPU core 21 is connected via the communication bus 22 to a connector 23 to which the terminals of the game cartridge 7 are connected, an input / output interface (I / F) circuit 24, and a calculation process necessary for displaying 3D graphics. 1, a second GPU (Graphics Processing Unit) 25, 26, a RAM 27, an LCD controller 28, and a wireless communication unit 29 are connected. The touch panels 6a and 6b, the left and right speakers 9, 9 and the switch group 11 are connected to an input / output interface (I / F) circuit 24.

  First and second VRAMs (Video RAMs) 30 and 31 are connected to the first and second GPUs 25 and 26, respectively. These first and second GPUs 25 and 26 generate (update) game data that matches the progress of the game as needed based on the game data stored in the RAM 27 in accordance with instructions received from the CPU core 21. Drawing is performed on the first and second VRAMs 30 and 31. The LCD controller 28 includes a register 32 in which a value of 0 or 1 is stored based on a command from the CPU core 21. In accordance with the value of 0 or 1, the game data drawn in the first or second VRAM 30, 31 is selectively output to the main display 4a or the sub display 4b via the LCD controller 28.

  Further, the game cartridge 7 includes a cartridge ROM 33 that stores a game program 35 and game data 36, which will be described later, and a RAM 34 that stores backup data in a rewritable manner. When the game cartridge 7 is inserted into the slot 8 shown in FIG. 1, the game program 35 and game data 36 stored in the cartridge ROM 33 through the connector 23 are stored in the RAM 27.

  The game data 36 includes well-known basic game data such as sound effects, fixed messages, background images, high scores, standby screens, HELP data, etc., as well as the game count / display count data shown in FIG. Data of many characters of the same type whose appearance is approximate and visually confusing.

  In this embodiment, the game count / display count data is set so that the number of characters to be displayed gradually increases for each game from the first question to the fifth question. Since the displayed number is the number of character pairs, the number of characters actually displayed on the main display 4a is doubled.

  In the present embodiment, three levels of difficulty, “easy”, “normal”, and “difficult”, are set based on the ease of character identification, and the number of characters displayed varies depending on the difficulty level. Is set. When the difficulty is increased by mixing dummy characters that do not form a pair (the same character does not exist), the number or ratio of the dummy characters may be stored as the game number / display number data. preferable.

  In the character data, a plurality of types of character groups whose appearances are so approximate that they are difficult to identify at first glance are associated with the serial number (01 to 99) and character type code (A to Z) of each character. Stored. At the start of the game, an arbitrary number of characters are extracted from these character groups and duplicated to form a character pair. The duplicated characters have the same serial number and type code, but as shown on the main display 4a in FIG. 1, the display mode such as size, color, display angle, front and back, and traveling direction is different for each pair of characters. Can be different. This display mode is appropriately changed depending on the difficulty level, the number of times of play, the experience value of the player, and the like shown in FIG.

  Each character is classified into one of the above three levels of difficulty, and is stored in association with a code indicating the difficulty level. For example, as the character “Easy (E)”, hiragana and Arabic numerals shown in FIG. 4A, and as the character “Normal (N)”, katakana, two-dimensional figure, alphabet, “ As the character “difficult (D)”, Roman numerals shown in FIG. 4C, Chinese characters having a common radical (crown, partial, posture, etc.), a three-dimensional image, and the like are stored. When the player selects the difficulty level at the start of the game, the character associated with the code is arbitrarily extracted by the display number and displayed on the display. Note that uppercase and lowercase letters of the alphabet, Arabic numerals, Roman numerals, and Chinese numerals may be displayed in combination.

  In the following description, “Hiragana” will be described as an example of a character belonging to “Easy (E)”. The displayed character group or individual characters are collectively referred to as “character object (OBJ)”.

  In the RAM 27, during the game play, the display position (x: 000 to 999, y: 000 to 999), touch acceptance, together with the serial number and the character type code described above for all the characters OBJ to be displayed on the main display 4a. Each data of the range width (x ± 5), height (y ± 5), and marker flag (0, 1) is described. In the present embodiment, since the position of the character OBJ on the main display 4a is constantly changing, the display position and the width of the touch acceptance range are updated as needed.

  The game program 35 includes a character display unit (character erasing unit) 40, a character recognition unit 41, an identity determination unit 42, a results determination unit 43, a communication control unit 44, and a synchronization processing unit 45. These functional units are actually game program modules, subroutines, or independent programs, which are read out and executed on the RAM 27 by the CPU core 21 or the GPUs 25 and 26 to cooperate with the hardware described above. And perform each function.

  The character display unit 40 randomly extracts a character group of the corresponding type from the RAM 27 according to the difficulty level (E, N, D) selected by the player, and the pair of characters determined to be the same by the identity determination unit 42. The OBJ is deleted from the game screen. The extracted character group is combined with the game basic data by the GPUs 25 and 26 and displayed on the main display 4a. In this embodiment, when the character OBJ moves in the game screen and touches the wall or other character at the edge of the screen, the movement is controlled so that the direction of movement and the display direction are changed randomly. . Such operation control is performed in the same manner as a well-known electronic game, and is mainly executed by the GPUs 25 and 26. An obstruction having an arbitrary shape and size may be fixedly displayed at the center of the display, and the traveling direction of the character OBJ may be changed even when the obstruction is touched.

  In addition, the character display unit 40 dynamically changes the color, size, display direction, rotation direction, rotation speed, traveling direction, traveling speed, and the like for some or all characters OBJ depending on the difficulty level and the number of games. Or change statically. As shown in FIG. 1, in Chinese characters and geometric figures, the discriminability can be lowered by reversing the front and back or changing the moving speed. Thereby, it is easy to adjust the difficulty level other than the character type, and a complicated game can be provided. A pattern (algorithm or the like) for changing the display mode such as the color and size of the game character is described in a display pattern table (not shown), and the GPUs 25 and 26 read out this display pattern at random or according to a predetermined rule. The display mode of each character OBJ is changed.

  The character recognition unit 41 identifies the character OBJ displayed on the main display 4a based on the coordinate position of the main display 4a (touch panel 6a) touched (selected) by the player with the touch pen 5, and serializes the character OBJ. The number is written in the RAM 27. The recognizable range is a range wide from the display position of the character OBJ by the width (x ± 5) and height (y ± 5) of the touch acceptance range.

  In addition, as will be described later with reference to FIG. 7A, the character recognizing unit 41 has a rectangular frame (marker) indicating that “the selected character” is “selected” for the first character OBJ of the paired character OBJ. ) Is also written to the RAM 27 at the same time for identifying that the display is being displayed on the display 4a. When this flag is recorded, the character display unit 40 stops the operation (movement, rotation, etc.) of the character OBJ and displays the marker on the outer periphery of the recognizable range. Therefore, when the character OBJ is selected, if the flag is not stored in the RAM 27, the character recognition unit 41 determines that the character is the first character (= not selected), writes the flag, and conversely stores the flag. If it is, the second character (= selected) is determined, the flag is not written, the serial number of the character OBJ is transferred to the identity determination unit 42, and the process waits until a determination result is obtained.

  When the identity determination unit 42 receives the serial number of the second character OBJ from the character recognition unit 41, the identity determination unit 42 collates with the serial number of the “selected” character OBJ stored in the RAM 27 to check the two characters OBJ. Are the same. In addition, when character recognitions of different types such as kanji and how to read them, Arabic numerals and Roman numerals are selected as a pair, an identification symbol indicating the association of these characters is registered separately from the serial number. The identity determination unit 42 determines that these characters are a pair when either the identification symbol or the serial number matches.

  The grade determination unit 43 measures the time required for erasing a predetermined number of character OBJ pairs by a time counting function using a pulse or the like, and records it in the RAM 27 as the grade of the player. As an example, a form in which five games are set as one set and the total time is competed is adopted. Here, the “predetermined number” of characters OBJ is preset according to the difficulty level and the number of games, as shown in FIG. In the present embodiment, the time limit is set to 60 seconds (1 minute) regardless of the degree of difficulty and the number of times, and when the predetermined number of character OBJ pairs cannot be deleted within this time, the grade determination unit 43 Records the result as “time over”. Note that the performance (time) data recorded in the RAM 27 is transferred to the RAM 33 of the game cartridge 7 when the game cartridge 7 is taken out or the power of the game machine 1 is turned off after one set of five games. To be recorded.

  The criteria for grade determination may be any criteria related to character erasure. For example, the number of characters erased per unit time (number of pairs), the attributes of the erased characters (kanji for high scores, hiragana and Arabic numerals) May be adopted. Further, the time limit, the number of times, the number of characters OBJ, and the like may be changed according to the degree of difficulty, the number of times, the experience value of the player, and the like.

  In the present embodiment, the synchronization processing unit 45 that displays the same game data in synchronization with other game machines in communication, and wireless data by infrared with other game machines by controlling the wireless communication unit 29 And a communication control unit 44 that performs communication. For example, when wireless communication is performed between a plurality of game machines, a game program is executed with one of them as a host. The same game data (such as a character) is displayed on the displays of the host and other clients by the communication control unit 44 and the synchronization processing unit 45.

  As a way of playing in this case, a “cooperation mode” in which a plurality of players cooperate to erase the same character group, a “quick press competition” in which the number of characters that can be erased within the time limit is competed, and the same game (character "Time trial" that competes for time to play and clear (type, action, number, etc.) in order. In the cooperation mode or the fast-pressing competition, the synchronization processing unit 45 determines whether the player selects the same character OBJ or displays a marker on the character OBJ selected by another player. Processing is instructed to each processing unit. Note that other game machines in this case may be PCs or home game machines as well as the same kind of game machines shown in FIG.

  Next, detailed functions and specific processing steps of the game program of this embodiment will be described with reference to the flowchart of FIG. 5 and the game screen examples of FIGS. 6 and 7. In the following description, an example is shown in which “Easy” is selected as the difficulty level and “Hiragana” is extracted as the character type. 6 and 7, the upper screen is a game screen displayed on the sub display 4b and the lower screen is displayed on the main display 4a. It should be noted that the processing steps common to the game machine other than the above-described characteristic functions of the present invention will be described with the control means (CPU core 21, GPUs 25, 26, etc.) as the execution subject.

  First, when the player inserts the game cartridge 7 into the slot and turns on the power switch, the control means reads the game data and program from the cartridge 7 and generates the initial menu screen shown in FIG. To display. When the player touches the touch panel 6 with a touch pen 5 or a finger, or operates a cross key or the like to select a game type, the control means receives the operation signal (S1). Here, the “discriminating power game” surrounded by a broken line is selected.

  When the game type is selected, the control means displays the difficulty level selection screen shown in FIG. 6B on the display 4 and similarly accepts the player's selection (S2). Here, “Easy” surrounded by a broken line is selected.

  Next, the character display unit 40 is activated, and from the game data read into the RAM 27, “Hiragana” is selected from the character types (see FIG. 4A) to which the “difficulty level: easy (E)” code is assigned. Is extracted (S3). Specifically, since it is the first question at this time (number of games (n) = 1), with reference to the table of FIG. 3, “5” in the case of “Easy” and “First question” is specified. Then, five hiragana characters are randomly extracted from the character data shown in FIG. 4A, and these are duplicated to generate a character OBJ group consisting of a total of ten characters. In addition, the character display unit 40 extracts a display mode pattern of the character OBJ from a pattern table (not shown), and determines a display mode (motion or the like) of each character OBJ. Until this preparation process is completed, the display 4 displays a countdown until the game starts (FIG. 6C).

  When the preparation process is completed, the game screen of FIG. 6D is generated and displayed on the display 4 to start the game (S4). Specifically, the character recognition unit 41 immediately starts monitoring the player's character selection, and the grade determination unit 43 starts counting up for a time limit of 60 seconds and displays the timer on the display 4.

  In the example shown in the drawing, a cross-shaped shield 50 that is always displayed on the surface (upper surface) than the character OBJ is displayed at the center of the main display 4a to increase the difficulty. In the state of FIG. 6D, one of the “me” characters OBJ surrounded by the alternate long and short dash line is shielded by the shielding object 50 and is difficult to recognize. As described above, since the position of the character OBJ on the game screen is constantly changing, even the character OBJ that is covered with the shielding object 50 and is difficult to visually recognize becomes visible. Further, in the illustrated example, characters OBJ (“wa” surrounded by a one-dot chain line) not forming a pair are also mixed. Thus, by displaying the dummy characters OBJ, it becomes possible to give a change to the play.

  When the player touches an arbitrary position on the display 4 (touch panel 6) with the touch pen 5 or the like, the character recognizing unit 41 acquires coordinate position information touched from the touch panel 6 and displays all the information displayed on the display 4. The current coordinate position of the character OBJ and the surrounding touch acceptance range are collated to recognize which character OBJ has been touched (S5). The current coordinate position of the character OBJ and the touch acceptance range around the character OBJ are recorded in the RAM 27 and updated as needed with the operation of the character OBJ.

  When the selection of the character OBJ is detected (YES in S5), the character recognizing unit 41 determines whether the character OBJ is the first character based on whether the “selected” marker display flag is recorded in the RAM 27. (S6). If the flag is not recorded (Yes in S6), it is determined that the character is the first character, the flag is recorded for the selected character OBJ, and the OBJ number of this character is used as the character OBJ serial number for marker display. Set. As a result, the marker display shown in FIG. 7A is started and the process returns to the character selection standby state in S5 (S7). The same processing is performed when the dummy data (“WA” in the figure) is selected.

  On the other hand, when the flag is recorded (No in S6), the identity determination unit 42 is activated and the serial number of the second character OBJ selected later and the marker recorded in the RAM 27 are being displayed. Is compared with the serial number of the character OBJ (S8). If the serial numbers of the two match (Yes in S8), the character display unit 40 deletes the corresponding two characters OBJ from the game screen (S9). If the two serial numbers do not match (No in S8), the marker display flag is deleted from the RAM 27 and the marker display is stopped (S10).

  The above-described processing from S5 to S10 is continued until all pairs to be erased (5 pairs in the illustrated example) disappear or until the time limit (60 seconds) elapses (S11, S12).

  When all the pairs to be deleted are deleted (No in S11), the score determination unit 43 determines that the player has cleared the first question, and displays the clear screen shown in FIG. 7B (S13). Counting up is stopped (S14), and the time is recorded in the RAM 27 (S15).

  On the other hand, if the time limit is exceeded in the above-described steps (No in S5, S10, S11) (Yes in S12), the time-out screen in FIG. 7C is displayed on the display (S16), and the time of that time Is recorded in the RAM 27 as "timeout" (S17).

  When the player selects the “Proceed” button on the clear screen in FIG. 7B or the timeout screen in FIG. 7C, the number of games (n) is incremented and the process returns to S3 to start the second question (S19). ). This is repeated up to the fifth question (S18).

  When the fifth question is finished (Yes in S18), the score determination unit 43 totals the five times of the player, generates a game screen displaying a list of each time, and as shown in FIG. 7D. Is output to the display 4 (S20). Thereby, a series of games are completed. If there is a time out of 5 questions, the total time will not be counted as shown in the example in the figure. A plurality of prepared messages are displayed according to the total time, average time, difficulty level, and the like. As described above, the time, total time, “timeout” flag, ranking, and other information measured by the score determination unit 43 are stored in the game cartridge 7 from the RAM 27 of the game machine 1 at a predetermined timing such as after the game ends. Are transferred to the RAM 34.

(Modification)
In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention.

  For example, in the above embodiment, the character type is set according to the difficulty level, but the difficulty level of all types of characters is the same, and it is difficult to change the display / motion mode or change the time limit. The degree may be adjusted. Alternatively, the selection of the difficulty level may not be accepted, and the difficulty level may be automatically set so as to gradually increase as the number of questions increases from 1 to 5.

  Further, the selection of the selected character is not limited to the frame-shaped marker described above, and the character may be blinked or displayed on a sub display or another window. In this case, it is not necessary to stop the action of the selected character.
