  The progress and control of the game in the sparrow ball game machine 10 are generally performed as follows by a main control board (described later) built in the housing 30 performing arithmetic processing according to a predetermined program.

  First, when a player inserts a predetermined number (for example, three) of medals into the medal insertion unit 40 and presses the BET button 43, the main control board has 14 cards as a hand at the start of the game. Are determined by an internal lottery using random number generating means. Then, the 14 automatically arranged wrinkle symbols are displayed on the effect control liquid crystal display device 14, and the code data of the arranged symbols are stored in the memory.

  The main control board refers to the code data of this game (hand game), and unnecessary masonry that cannot complete any mahjong role (raising role) or the difficulty level selected by the player at the start of the game ( The bags to be discarded are selected in accordance with the criteria of whether to aim for big roles or small roles, and display (navigate) those symbols on the effect control liquid crystal display device 21. With reference to the displayed symbols, the player presses the discard button 42 corresponding to a single basket determined to be unnecessary by himself / herself and performs the discard operation. At this time, the main control board updates the code data of the hand in accordance with the discarding operation, and causes the effect control liquid crystal display device 14 to display the thirteen hands. Then, the main control board supplies one game ball to the ball launcher 740 and prepares for ball launch (launch).

  At the same time, the main control board calculates a rising combination that may be established from the 13 hands, and selects a target rising combination based on the set difficulty level. Then, a bag that is not included in the rising hand is selected as a bag to be self-recognized, and the design is displayed on the effect control liquid crystal display device 21 for guidance.

  Next, the player operates the ball launch lever 81 to launch a single game ball onto the game board surface 20, thereby performing a self-control operation to drop the game ball into any of the entrances 25a, 25b, and 28. Then, the main control board adds the bag corresponding to the entrance that detected the falling of the game ball as a bag (self-locking). In other words, the code data of the self-contained heel is added to the code data of the hand before the self-operation and updated, and the design of the self-contained heel is displayed on the effect control liquid crystal display device 14.

  At this time, the main control board performs a process of determining whether or not the combination of 14 hand-stamped symbols by this self-operation has completed a preset up (completion) combination. If the hand tile has not completed any rising combination, the main control board selects the bag to be discarded in the same manner as the above-described processing, and displays the symbol on the effect control liquid crystal display device 21 as a guide. Then, the player again performs a discarding operation for throwing away unnecessary bags from the hand.

  The player repeats such discarding and self-repetition operation using, for example, 11 game balls given to one game, and before using up all the game balls, the player can perform any one of the rising roles. When the combination is completed, a predetermined number of medals are paid out from the medal exit 52 to the tray 51 for each rising combination.

  On the other hand, if the player has used all the given number of game balls and has failed to complete any of the rising roles, the main control board performs processing to end (game) the game. .

  In addition, if the rising combination completed by the player is the same as a specific rising combination (for example, “Dai Sangen”) determined by an internal lottery using random number generation means at the start of the game, For a predetermined number of games, a special game combination (bonus game combination) that is more advantageous to the player than a normal game is provided.

  In general, the sparrow ball game machine 10 is provided with two types of roles, a big game role and a chance game role, as special game roles. A big game combination is advantageous to a player with respect to a predetermined number of games including the game when it is raised in a specific rising combination (for example, “Kokushi Musou” or “Daisangen”) that has been drawn in advance. A role that gives conditions.

  That is, in a game in which the big game combination is activated, the gate 26 of the game board surface 20 becomes effective, and when the launched game ball passes through the gate 26, the door of the attacker 24 is opened. When the game ball falls into the attacker 24, the player can arbitrarily select a desired basket as his / her own by operating the shift buttons 45a, 45b, the selection determination button 46, and the like. Then, when the player completes the rising combination in the game in which the big game combination is activated, the player can obtain a higher score (number of medals) than usual.

  Next, a chance game combination means that if a player goes up with a specific rising combination (for example, “Peace”, “Ichiguchi”, etc.) that has been drawn in advance, the number of points earned in that game will be higher than that of a normal game. It is a combination that adds or makes the above-mentioned big game combination effective only for the next one game.

  Note that the sparrow ball game machine 10 is provided with score increasing means for increasing the number of points more than usual when the game is completed under the condition of the rising combination set in advance, in addition to the special game combination.
