  • FIG. 28 shows a flowchart of the BR execution process.
  • sub-CPU 203 checks the BR flag and a BR evacuation flag in sub-RAM 205 to determine whether or not BR game is currently in progress or a bonus has been generated during BR and the BR gaming state is temporarily interrupted (ST 681 ). If determined as “NO,” since this means that the present state is not the BR state, a return to the attraction control process for starting is performed as it is.
  • the receiving flag in sub-RAM 205 is checked to determine whether or not a bonus winning combination has been won internally (ST 682 ), and if determined as “YES,” the BR is interrupted, the BR flag in sub-RAM 205 is set to off and the BR evacuation flag is set to on in order to finish up the bonus game (ST 683 ), and a return to the attraction control process for starting is performed.
  • the BR evacuation flag in sub-RAM 205 is set to off and the BR flag is set to on (ST 684 ).
  • the BR continuance number in sub-RAM 205 is then checked to check whether all of the BR continuance number of times of game have been finished and determine whether or not the continuance number has become 0 (ST 685 ). If determined as “YES,” since this means that BR has ended, the BR flag is set to off (ST 686 ) and a return to the attraction control process for starting is performed.
  • the receiving flag in sub-RAM 205 is checked to determine whether or not the bell or SB has been won internally in the present game (ST 687 ). If determined as “YES,” the selected stop table category, stored in the receiving flag in sub-RAM 205 , is referenced and the appropriate order of stopping is notified (ST 688 ) and a return to the attraction control process for starting is performed.

If determined as “NO,” the BR flag stored in sub-RAM 205 is checked to determine whether or not the current state is the BR state (ST 742 ). If determined as “NO,” a return to the attraction control process for the completion of one game is performed as it is. If determined as “YES,” the BR continuance number counter in sub-RAM 205 is decremented (ST 743 ) and then a return to the attraction control process for the completion of one game is performed.
  • the present embodiment is described with the ST period as an advantageous status for the player that is established by achieving the present object, the above-mentioned AT period may be applied instead or as an advantageous status for the player.
  • the winning flag of a specific prize pattern may be established or the internal winning probability of a prize pattern may be increased.
  • this invention may be applied in a similar manner to a pachinko gaming machine or an arcade gaming machine equipped with an electrical display device or to a home video game that executes the above-described functions in a simulating manner with a software.
  • the present invention enables the Super Time (ST) gaming state to be completed without movement of the sight line from the image display device, on which the stopping order is displayed, to the reels, thus alleviating the degree of fatigue of the player. Furthermore, switching between the transmitting and shielding states can be performed instantaneously in accordance with the game conditions, and since the shielded areas can be controlled by software, finer attraction control is enabled.
