Game apparatus and game controlling method

Abstract

A game apparatus possesses a symbol display controlling function, a parameter controlling function and a granting function. The symbol display controlling function makes one or a plurality of symbols randomly displayed. The parameter controlling function increases a value of a parameter which has been set in advance in correspondence with a displayed number of predetermined symbols in a plurality of parameters in accordance with a result of display of the symbol(s) by the symbol display controlling function. When the value of the parameter has reached a predetermined value, the granting function grants a privilege according to the parameter which has reached the predetermined value concerned. The game apparatus realizes a game of higher entertaining property.

What is claimed is: 
     
         1 . A game apparatus comprising a control unit and a storage unit, wherein the control unit is configured to execute a program stored in the storage unit and thereby to carry out actions comprising:
 displaying one or more symbols on a display device;   increasing, in accordance with the displayed symbols, a value of a parameter which has been set in advance in correspondence with a displayed number of predetermined symbols in a plurality of pre-set parameters;   when the value of the parameter has reached a predetermined value, storing, in a database, data indicating that a user has been granted a privilege according to the parameter which has reached the predetermined value concerned; and   clearing the value of the parameter while maintaining the values of other parameters that have been set in accordance with a displayed number of symbols that are different from the predetermined symbols.   
     
     
         2 . The game apparatus according to  claim 1 , wherein the more valuable privilege the granting function grants, the more number of the predetermined symbols which has been set in advance in correspondence with the parameter which has reached the predetermined value is displayed. 
     
     
         3 . The game apparatus according to  claim 2 , wherein the more number of times the granting function grants a right to play a free game as the privilege, the more number of the predetermined symbols which has been set in advance in correspondence with the parameter which has reached the predetermined value is displayed. 
     
     
         4 . The game apparatus according to  claim 1 , wherein the parameter controlling function determines an amount of the parameter to be increased by lottery. 
     
     
         5 . A game apparatus comprising:
 a control unit; and   a storage unit out of/into which data reading and writing are made from the control unit, wherein   the control unit is programmed:
 to manage execution of a game, 
 to read one or a plurality of symbol(s) out of the storage unit, 
 to make the read-out one or plurality of symbols for every playing of the game displayed, 
 to read a value of a parameter which has been set in advance in correspondence with a displayed number of predetermined symbols in a plurality of parameters which has been set in advance out of the storage unit, to increase, in accordance with the displayed symbol, the read-out value of the parameter concerned by a predetermined amount and to write the increased value into the storage unit, 
 to read the values of the plurality of parameters out of the storage unit and to decide whether the value of any of the parameters reaches a predetermined value, 
 to write data indicating that it is possible to utilize a privilege according to the parameter which has reached the predetermined value concerned into the storage unit when it has been decided that the value of the parameter reaches the predetermined value; and 
 to clear the value of the parameter while maintaining the values of a remainder of the plurality of parameters that have been set in accordance with a displayed number of symbols that are different from the predetermined symbols. 
   
     
     
         6 . A game controlling method which is performed by a game apparatus which possesses a control unit and a storage unit, the method comprising:
 displaying one or more symbols on a display device;   increasing, in accordance with the displayed symbol, a value of a parameter which has been set in advance in correspondence with a displayed number of predetermined symbols in a plurality of pre-set parameters;   when the value of the parameter has reached a predetermined value, storing, in a database, data indicating that a user has been granted a privilege according to the parameter which has reached the predetermined value concerned, and   
       clearing the value of the parameter while maintaining the values of other parameters that have been set in accordance with a displayed number of symbols that are different from the predetermined symbols.
