Description

【0001】
【発明の属する技術分野】
本発明は、パチンコ機、アレンジボール機等の弾球遊技機に関するものである。
【0002】
【従来の技術】
パチンコ機等の弾球遊技機では、遊技盤に図柄始動手段と、1又は複数個の図柄が所定時間変動して停止する図柄変動表示手段と、遊技者に有利な第1状態と不利な第2状態とに変換駆動する大入賞手段等の可変入賞手段とを備え、図柄始動手段が遊技球を検出することを条件に乱数処理による抽選遊技処理を行って図柄変動表示手段の図柄を所定時間変動させ、その抽選遊技の結果、即ち図柄変動表示手段の図柄が大当たり図柄で停止したときに、特賞付与手段が働いて可変入賞手段を第1状態に変換駆動する等、遊技者に有利な利益状態を付与するようにしたものがある。
【0003】
この種の弾球遊技機では、例えば特賞抽選確率(大当たり確率)が1/401の場合、抽選遊技判定処理手段では、その特賞抽選乱数用カウンタ(大当たり乱数用カウンタ)が、特賞抽選判定値(大当たり判定値)を含む0〜400までの特賞抽選乱数(大当たり乱数)を一定周期で繰り返し発生して、図柄始動手段が遊技球を検出することを条件に特賞抽選乱数(大当たり乱数)の乱数値を抽出し、その乱数値が予め設定された一定の特賞判定値(大当たり判定値)のときに図柄変動表示手段の変動後の停止図柄が特賞図柄(大当たり図柄)となるように処理を行っている。
【0004】
【発明が解決しようとする課題】
この弾球遊技機では、特賞抽選乱数用カウンタ(大当たり乱数用カウンタ)が0〜400までの範囲の特賞抽選乱数(大当たり乱数)を一定周期で繰り返し発生し、その中の特定の乱数値を特賞判定値(大当たり判定値)として固定的に設定しており、特賞判定値(大当たり判定値)を含む全ての乱数値が常に一定周期で発生する。このため、従来の弾球遊技機では、何等かの手段により同期を取れば、特賞判定値(大当たり判定値)の周期性やタイミングを容易に特定でき、一定周期で発生する特賞判定値(大当たり判定値)を抽出して不正に特賞(大当たり)を的中させることが可能であり、所謂ぶら下げ基板等の不正行為を招き易い欠点がある。
【0005】
本発明は、このような従来の問題点に鑑み、特賞抽選乱数(大当たり乱数)の特賞判定値(大当たり判定値)を変化させて、特賞判定値(大当たり判定値)の周期性をなくし、周期性に伴う不正行為を未然に防止できる弾球遊技機を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明は、遊技盤4 の遊技領域12に複数種類の入賞手段14,15,17〜19を備え、該複数種類の入賞手段14,15,17〜19の内、特定の入賞手段14への遊技球の入賞を条件として乱数処理により作動する抽選遊技機能と、該抽選遊技機能による抽選遊技によって抽選された特賞抽選乱数値が特賞判定値のときに、その抽選遊技の結果により遊技者に有利な状態を付与する特賞付与機能とを備えた弾球遊技機において、前記特賞判定値を、前記抽選遊技機能による抽選遊技によって前記特賞判定値が取得される毎、及び前記抽選遊技機能による抽選遊技によって特定の外れ乱数値が取得される毎に切り替える特賞判定値切替手段36を設け、該特賞判定値切替手段36は、遊技プログラムで更新する判定値切替用カウンタ39を備え、前記特賞判定値の取得と前記特定の外れ乱数値の取得とを条件に夫々該判定値切替用カウンタ39の乱数値を前記特賞判定値とするようにしたものである。
【0007】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳述する。図1〜図4は本発明の第1の実施形態を例示し、図1において、1 は遊技機本体で、開閉自在に枢着された前枠2 を有する。前枠2 には、その窓孔3 に対応して遊技盤4 が裏側から着脱自在に装着され、この遊技盤4 の前側にガラス扉5 と前面板6 とが開閉自在に配置されている。前面板6 には、発射用の遊技球を貯留する上皿7 が装着されている。
【0008】
前枠2 の下部には、余剰球を貯留する下皿8 と、発射手段9 の発射ハンドル10とが夫々設けられている。発射手段9 は、遊技者が発射ハンドル10を把持して操作したときに打撃槌駆動用の発射モータが作動して、上皿7 から1個ずつ発射レール上に供給される遊技球を打撃槌により打撃し遊技盤4 側に発射させるようになっている。
【0009】
遊技盤4 には、図2に示すように、ガイドレール11が環状に装着されると共に、そのガイドレール11の内側の遊技領域12に液晶表示手段13、第1図柄始動手段(特定の入賞手段)14、可変入賞手段15、第2図柄始動手段16、普通入賞手段17〜19等の遊技部品が配置されている。
【0010】
液晶表示手段13は、液晶表示部20に第1図柄変動表示手段21を備え、その液晶表示部20の上側に第2図柄変動表示手段22が配置されている。第1図柄変動表示手段21は1個又は複数個、例えば3個の図柄表示部を左右方向に備え、その各図柄表示部に例えば「0」〜「9」までの10種類の数字図柄(第1図柄)を発光表示するようになっている。なお、第1図柄変動表示手段21は、第1図柄始動手段14が入賞した遊技球を検出することを条件に、第1図柄が乱数制御により所定時間変動して停止するように構成されている。
【0011】
第2図柄変動表示手段22は1個又は複数個、例えば1個の図柄表示部を有し、「0」〜「9」までの10種類の数字図柄(第2図柄)を発光表示するようになっている。なお、第2図柄変動表示手段22は、第2図柄始動手段16が遊技球を検出することを条件に、その第2図柄が乱数制御により所定時間変動して停止するように構成されている。
【0012】
第1図柄始動手段14は、開閉自在な左右一対の開閉爪23と、この開閉爪23を開閉駆動するソレノイド等の電気的駆動源(図示省略)とを備えた電動式チューリップ等の開閉入賞手段により構成され、第2図柄変動表示手段22の変動後の停止図柄が奇数図柄等の当たり図柄となったときに、開閉爪23が所定時間(例えば0.5秒程度)開放するようになっている。第2図柄始動手段16は遊技球が通過する通過ゲートにより構成されている。
【0013】
可変入賞手段15は、下部側の横軸廻りに入賞口を開閉する開閉板24と、この開閉板24を遊技者に有利な開状態(第1状態)と不利な閉状態(第2状態)とに変換駆動するソレノイド等の電気的駆動源(図示省略)とを備えた電動開閉式であって、第1図柄変動表示手段21の変動動作後の3個の停止図柄が特定図柄、例えば「7・7・7」等のように全てが同一種類の数字図柄となる大当たり図柄(特賞図柄)のときに、開閉板24が前側に開放するようになっている。可変入賞手段15内には特定領域25が設けられており、この特定領域25を入賞球が通過したときに、大当たり(特賞)による利益状態を継続させるようになっている。
【0014】
可変入賞手段15は、開放後に所定時間が経過したとき、又は所定数(例えば10個)の遊技球が入賞したときに開閉板24が閉じると共に、遊技球が特定領域25を通過することを条件に、最大所定回数(例えば16回)まで開閉動作を繰り返すようになっている。可変入賞手段15の左右両側には、1個又は複数個(例えば2個)の普通入賞手段18,19 が夫々設けられている。
【0015】
図3は制御系を例示するブロック図である。26は遊技制御手段で、CPU、ROM、RAM等により構成され、ROMに格納された遊技制御プログラムに沿って、主として遊技盤4 側の遊技動作を制御する機能を有する。遊技制御手段26は、第1図柄変動表示手段21に関連する制御を行う第1制御系27と、第2図柄変動表示手段22に関連する制御を行う第2制御系28と、その他の各種の制御を行う各種制御系29とにより構成されている。
【0016】
第2制御系28は、当たり判定処理手段30と第2図柄変動制御手段31と開閉制御手段32とを備えている。当たり判定処理手段30は、第2図柄始動手段16が遊技球を検出することを条件に第2図柄変動表示手段22の停止図柄が当たり図柄を表示するか否かを乱数処理にて判定するもので、第2図柄始動手段16が遊技球を検出したときに、所定周期で繰り返し発生する当たり・外れ決定用の当たり乱数の乱数値を抽出し、それが当たり判定値のときに当たりと判定するようになっている。
【0017】
第2図柄変動制御手段31は、第2図柄始動手段16が遊技球を検出することを条件に第2図柄変動表示手段22の第2図柄を所定時間変動させる機能と、当たり判定処理手段30が当たりと判定することを条件に第2図柄変動表示手段22の第2図柄を所定の当たり図柄(例えば奇数図柄)で停止させるように制御する機能とを有する。開閉制御手段32は、第2図柄変動表示手段22の停止図柄が当たり図柄を表示することを条件に第1図柄始動手段14の開閉爪23を所定時間(例えば0.5秒程度)開放させるようになっている。
【0018】
第1制御系27は、大当たり判定処理手段(特賞乱数判定処理手段)33と第1図柄変動制御手段34と特賞付与手段35と大当たり判定値切替手段(特賞判定値切替手段)36とを備えている。
【0019】
大当たり判定処理手段33は、第1図柄始動手段14が遊技球を検出することを条件に乱数処理により作動して、第1図柄変動表示手段21の停止図柄が大当たり図柄を表示するか否かを乱数処理により抽選し判定する抽選遊技機能を備え、大当たり乱数用カウンタ(特賞抽選乱数用カウンタ)37と大当たり判定手段(特賞判定手段)38とを含んでいる。
【0020】
大当たり乱数用カウンタ37は、例えば大当たり確率(特賞確率)が1/401の場合、遊技制御プログラムが終了する毎に初期値から順次カウントするカウント動作を繰り返し行って、大当たり判定値(特賞判定値)を含む0〜400までの大当たり乱数(特賞抽選乱数)を一定周期で順次発生するようになっている。大当たり判定手段38は第1図柄始動手段14が遊技球を検出することを条件に、そのときの大当たり乱数用カウンタ37の乱数値を抽出して、その乱数値が予め可変的に設定された大当たり判定値と一致したときに大当たりと判定するようになっている。
【0021】
第1図柄変動制御手段34は、第1図柄始動手段14が遊技球を検出することを条件に第1図柄変動表示手段21の第1図柄を所定時間変動させる機能と、大当たり判定処理手段33が大当たり乱数の乱数値の内、大当たり判定値を抽出する抽選遊技の結果により第1図柄変動表示手段21の停止図柄に大当たり図柄を表示させる機能と、複数種類の大当たり図柄の中から第1図柄変動表示手段21の停止図柄に表示すべき大当たり図柄を抽出し決定する機能と、大当たり判定処理手段33が大当たり乱数の乱数値の内、大当たり判定値以外の外れ乱数値を抽出することを条件に第1図柄変動表示手段21の停止図柄に外れ図柄を表示させる機能とを備えている。
【0022】
なお、第1図柄変動制御手段34は、第1図柄変動表示手段21の変動動作中に第1図柄始動手段14が遊技球の入賞を検出したときに、所定個数(例えば4個)までの入賞を記憶し、その記憶個数の範囲内で第1図柄変動表示手段21の変動終了後に変動・停止を継続させるようになっている。
【0023】
特賞付与手段35は、第1図柄変動表示手段21の停止図柄が「7・7・7」等の大当たり図柄を表示することを条件に遊技者に有利な利益状態を発生させるためのものである。特賞付与手段35は、第1図柄変動表示手段21が大当たり図柄で停止する大当たりの発生を条件に可変入賞手段15の開閉板24を開放する制御機能の他に、開閉板24の開放から所定時間が経過したとき、又は可変入賞手段15に所定数の遊技球が入賞したときに開閉板24を閉じ、また開放中に入賞した遊技球が特定領域25を通過することを条件に、最大所定回数まで開閉動作を継続させるように制御する機能を有する。
【0024】
大当たり判定値切替手段36は、予め設定された所定条件の成立により、乱数処理によって大当たり乱数中の大当たり判定値を切り替えて変化させるためのものである。この大当たり判定値切替手段36は、大当たり乱数の乱数値1〜401の数以下の数の切替乱数をカウントする判定値切替用カウンタ39を備え、特賞付与手段35による特賞付与毎にその特賞付与の終了を契機として、判定値切替用カウンタ39がカウントした切替乱数値を大当たり判定手段38の大当たり判定値に更新するようになっている。なお、この更新は、大当たり判定値を取得したことを契機としても可能である。
【0025】
判定値切替用カウンタ39は、図4に示すように、遊技制御手段26が遊技制御プログラムに沿ったプログラム処理を1割り込み時間T 毎に繰り返し行うことを利用して、1割り込み時間T 内のプログラム処理が終了し次のプログラム処理が開始するまでの残余時間t 内にカウント値を更新するように構成されている。
【0026】
次に上記弾球遊技機における動作について説明する。上皿7 に遊技球がある状態で発射手段9 の発射ハンドル10を操作すると、上皿7 の遊技球が発射手段9 の発射動作に連動して発射部に1個づつ供給され、その遊技球を打撃槌で打撃してガイドレール11に沿って順次遊技盤4 側へと発射させて行く。
【0027】
遊技盤4 の上部側に発射された遊技球が遊技盤4 の盤面に沿って落下する間に、その遊技球が第2図柄始動手段16を通過すると、第2図柄変動制御手段31が働いて第2図柄変動表示手段22の第2図柄を所定時間変動させる。一方、第2図柄始動手段16が遊技球を検出したときに、当たり判定処理手段30がその当たり乱数の乱数値を抽出して当たり判定値か否かにより当たり判定を行い、当たりであれば第2図柄変動表示手段22の停止図柄が所定の当たり図柄を表示するように停止させる。
【0028】
第2図柄変動表示手段22の停止図柄が当たり図柄となると、開閉制御手段32が働いて第1図柄始動手段14の一対の開閉爪23が開放する。このため第1図柄始動手段14に遊技球が入賞し易くなり、それだけ第1図柄変動表示手段21の第1図柄が変動し易くなる。
【0029】
第1図柄始動手段14の開閉爪23が開放して遊技球が入賞すると、第1図柄変動制御手段34が働いて第1図柄変動表示手段21の第1図柄が同様に所定時間変動する。一方、第1図柄始動手段14に遊技球が入賞すると、大当たり判定処理手段33が大当たり判定処理を行い、第1図柄変動表示手段21の変動後にその第1図柄を大当たり図柄で停止させるか否かを判定する。
【0030】
即ち、大当たり判定処理手段33では、遊技制御手段26全体の遊技制御プログラムのプログラム処理が1回終わる毎に大当たり乱数用カウンタ37がカウントし、大当たり乱数の1〜401までの各乱数値のカウント動作を繰り返しており、第1図柄始動手段14が遊技球の入賞を検出すると、大当たり判定手段38がその時点の大当たり乱数の乱数値を抽出する。そして、大当たり乱数の乱数値が例えば大当たり判定値75であれば、大当たり判定手段38が大当たりと判定し、第1図柄変動制御手段34が働いて第1図柄変動表示手段21の変動後の各図柄が「7・7・7」等の所定の大当たり図柄で停止する。
【0031】
第1図柄変動表示手段21の停止図柄が大当たり図柄を表示すると、特賞付与手段35が働いて開閉板24が前側に開放する第1状態に可変入賞手段15を変換駆動する。このため、遊技盤4 の上部側から落下する遊技球の多くが開閉板24を経て可変入賞手段15に入賞し易くなる。そして、可変入賞手段15に遊技球が入賞すると、払い出し制御手段により払い出し手段が作動して、その入賞球1個毎に15個の景品球を払い出して行く。従って、一旦、第1図柄変動表示手段21側で大当たりが発生すれば、遊技者に多大な利益が還元される。
【0032】
なお、可変入賞手段15は10個の遊技球が入賞するか、又は所定時間経過したときに開閉板24が閉じる。そして、開閉板24の開放中に入賞した遊技球が特定領域25を通過すれば、可変入賞手段15が再度開放し、最大16回まで開閉動作を繰り返す。
【0033】
遊技制御手段26では、図4に示すようにROMに格納された遊技制御プログラムに沿って1割り込み時間T 内のプログラム処理を一定周期で繰り返し行っている。そして、大当たり判定処理手段33では、大当たり乱数用カウンタ37がそのプログラム処理毎に順次昇順方向にカウントして、1〜401までのカウント動作を繰り返しており、第1図柄始動手段14からの検出信号を読み込んで、そのときの乱数値が大当たり判定値75か否かを判定して大当たり判定処理を行っている。
【0034】
また大当たり判定値切替手段36では、判定値切替用カウンタ39がプログラム処理の終了毎に1割り込み時間T の残余時間t に順次昇順方向にカウントして、1〜401までのカウント動作を繰り返している。そして、特賞付与手段35により特賞が付与された場合には、その特賞付与が終了した時点の判定値切替用カウンタ39の切替乱数値を大当たり判定値切替手段36が抽出して、その切替乱数値に大当たり判定手段38の大当たり判定値を更新する。例えば切替乱数値が350であれば、この乱数値に大当たり判定手段38の大当たり判定値を更新するので、大当たり判定手段38は、その大当たり判定値を350として判定動作を行う。
【0035】
従って、特賞付与手段35による特賞の付与があれば、その特賞付与が終了する毎に、大当たり判定値切替手段36がその判定値切替用カウンタ39の乱数値に大当たり判定手段38の大当たり判定値を切り替えるので、特賞付与手段35による特賞付与毎に大当たり判定手段38の大当たり判定値を変化させることができる。このため特賞付与毎に大当たり判定手段38の大当たり判定値が不規則に変化して、大当たり判定値の周期性がなくなるので、単に大当たり乱数の発生周期に同期を取るだけで、大当たり判定値のタイミングを把握して大当たりを不正に的中させるようなことはできない。
【0036】
また大当たり判定値切替手段36の判定値切替用カウンタ39は、遊技制御プログラムの1割り込み時間T 中の残余時間t に、そのプログラム処理に続いて更新処理を行っており、そのプログラム処理毎に処理時間が変化するため、残余時間t が変化することとなって、その乱数値の更新処理回数が不定となるので、その切替乱数値を不規則に変化させることができる。
【0037】
図5は本発明の第2の実施形態を例示し、大当たり判定値切替手段36が抽選遊技機能により抽選された特定の外れ抽選結果により作動して大当たり判定手段38の大当たり判定値を切り替えるようにしたものである。
【0038】
即ち、大当たり判定値切替手段36は、大当たり乱数用カウンタ37の大当たり乱数の内、予め設定された特定の外れ乱数値を抽出する特定外れ乱数値抽出手段40を備え、この特定外れ乱数値抽出手段40が特定の外れ乱数値を抽出したときに、判定値切替用カウンタ39の乱数値を大当たり判定手段38の大当たり判定値として更新するようにしたものである。
【0039】
従って、この場合にも、大当たり判定手段38の大当たり判定値を不規則に変化させることができる。また特定外れ乱数値抽出手段40に多数の乱数値を特定外れ乱数値としておけば、それらの乱数値を抽出する毎に大当たり判定値が変化するので、大当たり判定値を頻繁に変えることができる。
【0040】
なお、実施形態には、次の各発明が記載されている。その第1は、遊技盤4 の遊技領域12に複数種類の入賞手段14,15,17〜19を備え、前記複数種類の入賞手段14,15,17〜19の内、特定の入賞手段14への遊技球の入賞を条件として乱数処理により作動する抽選遊技機能と、該抽選遊技機能による抽選遊技によって抽選された特賞抽選乱数値が特賞判定値のときに、その抽選遊技の結果により遊技者に有利な状態を付与する特賞付与機能とを備えた弾球遊技機において、前記抽選遊技用の特賞抽選乱数の内、特賞判定値を予め設定された条件により切り替える特賞判定値切替手段36を設けたものである。
【0041】
第2は、図柄始動手段14と、1又は複数個の図柄が所定時間変動して停止する図柄変動表示手段21と、前記図柄始動手段14が遊技球を検出することを条件に前記図柄変動表示手段21の停止図柄が特賞図柄を表示するか否かを乱数処理にて判定する特賞判定処理手段33と、前記図柄始動手段14が遊技球を検出することを条件に前記図柄変動表示手段21の図柄を所定時間変動させ且つ前記特賞判定処理手段33が特賞抽選乱数の特賞判定値を抽出することを条件に前記図柄変動表示手段21に特賞図柄を表示させる図柄変動制御手段34と、前記図柄変動表示手段21が特賞図柄を表示することを条件に遊技者に有利な状態を付与する特賞付与手段35とを備えた弾球遊技機において、特賞判定値を予め設定された条件により切り替える特賞判定値切替手段36を設けものである。
【0042】
第3は、第1又は第2の発明において、前記特賞判定値切替手段36は、前記特賞付与機能による特賞付与毎に作動して特賞判定値を切り替えるようにしたものである。
【0043】
第4の発明は、第1又は第2の発明において、前記特賞判定値切替手段36は、前記抽選遊技により抽選された特定の外れ抽選結果により作動して特賞判定値を切り替えるようにしたものである。
【0044】
第5の発明は、第1〜4の何れかの発明において、前記特賞判定値切替手段36は、遊技プログラムの残余時間で更新する判定値切替用カウンタ39を備え、前記予め設定された条件が成立したときの該判定値切替用カウンタ39の乱数値を前記特賞判定値とするようにしたものである。
【0045】
以上、本発明の各実施形態を例示したが、本発明はこれに限定されるものではない。例えば、各実施形態の大当たり乱数の数、切替乱数の数は何れも例示であって、その数に限定されるものではない。また大当たり乱数の中に複数個の大当たり判定値を設定することも可能である。
【0046】
第1の実施形態では特賞付与毎にその終了時点で、また第2の実施形態では特定外れ乱数値を抽出する毎に、大当たり判定値切替手段36により夫々大当たり判定値を切り替えるようにしているが、両者を併用しても良い。またこれら以外の条件によって切り替えるようにすることも可能である。従って、切り替え条件は、予め設定された一定の条件であれば十分である。
【0047】
大当たり判定値切替手段36の切り替え乱数の数は、大当たり乱数の数以下であれば、その乱数値に直接大当たり判定値を更新できるので、処理が容易であるが、特別な処理を行う場合には、切替乱数の数を大当たり乱数の数よりも多くすることも可能である。
【0048】
遊技盤4 側の各遊技部品の組み合わせ、ゲーム構成等は自在に変更可能であり、大当たりにより付与する利益状態は、遊技者に有利になるものであれば十分である。その他、本発明は、第2図柄変動表示手段22の乱数処理にも採用可能であるし、パチンコ機は勿論のこと、アレンジボール機、雀球遊技機等においても同様に実施可能である。
【0049】
【発明の効果】
本発明では、遊技盤4 の遊技領域12に複数種類の入賞手段14,15,17〜19を備え、該複数種類の入賞手段14,15,17〜19の内、特定の入賞手段14への遊技球の入賞を条件として乱数処理により作動する抽選遊技機能と、該抽選遊技機能による抽選遊技によって抽選された特賞抽選乱数値が特賞判定値のときに、その抽選遊技の結果により遊技者に有利な状態を付与する特賞付与機能とを備えた弾球遊技機において、特賞判定値を、抽選遊技機能による抽選遊技によって特賞判定値が取得される毎、及び抽選遊技機能による抽選遊技によって特定の外れ乱数値が取得される毎に切り替える特賞判定値切替手段36を設け、該特賞判定値切替手段36は、遊技プログラムで更新する判定値切替用カウンタ39を備え、特賞判定値の取得と特定の外れ乱数値の取得とを条件に夫々該判定値切替用カウンタ39の乱数値を特賞判定値とするようにしているので、特賞抽選乱数の特賞判定値が変化して特賞判定値の周期性がなくなり、従来の特賞判定値の周期性に伴う不正行為を未然に防止できる利点がある。

It has become.
[0018]
The first control system 27 includes a jackpot determination processing means (special prize random number determination processing means) 33, a first symbol variation control means 34, a special prize granting means 35, and a jackpot determination value switching means (special prize determination value switching means) 36. Yes.
[0019]
The jackpot determination processing means 33 operates by random number processing on condition that the first symbol starting means 14 detects a game ball, and determines whether or not the stop symbol of the first symbol variation display means 21 displays a jackpot symbol. A lottery game function for lottery and determination by random number processing is provided, and a jackpot random number counter (special prize lottery random number counter) 37 and a jackpot determination means (special prize determination means) 38 are included.
[0020]
The jackpot random number counter 37, for example, when the jackpot probability (special prize probability) is 1/401, repeatedly performs a counting operation that sequentially counts from the initial value every time the game control program ends, thereby determining the jackpot determination value (special prize determination value) The jackpot random numbers (special prize lottery random numbers) from 0 to 400 including the number are sequentially generated at a constant period. The jackpot determining means 38 extracts the random value of the jackpot random number counter 37 at that time on condition that the first symbol starting means 14 detects a game ball, and the random number is variably set in advance. A jackpot is determined when it matches the determination value.
[0021]
The first symbol variation control means 34 has a function of varying the first symbol of the first symbol variation display means 21 for a predetermined time on condition that the first symbol starting means 14 detects a game ball, and the jackpot determination processing means 33 Of the jackpot random numbers, the function to display the jackpot symbol on the stop symbol of the first symbol variation display means 21 according to the result of the lottery game for extracting the jackpot judgment value, and the first symbol variation from the plural types of jackpot symbols The function of extracting and determining the jackpot symbol to be displayed on the stop symbol of the display means 21 and the condition that the jackpot determination processing means 33 extracts outlier random values other than the jackpot determination value from among the random numbers of the jackpot random number. 1 symbol variation display means 21 is provided with a function of displaying a disengaged symbol on the stopped symbol.
[0022]
It should be noted that the first symbol variation control means 34 receives up to a predetermined number (for example, four) of winnings when the first symbol starting means 14 detects a winning game ball during the variation operation of the first symbol variation display means 21. Is stored, and within the range of the stored number, the variation / stop is continued after the variation of the first symbol variation display means 21 is completed.
[0023]
The special prize granting means 35 is for generating a profit state advantageous to the player on the condition that the stop symbol of the first symbol variation display means 21 displays a jackpot symbol such as “7/7/7”. . In addition to the control function for opening the opening / closing plate 24 of the variable winning means 15 on condition that the first symbol variation display means 21 stops at the jackpot symbol, the special prize granting means 35 is a predetermined time from the opening of the opening / closing plate 24. The maximum number of times is determined on the condition that the open / close plate 24 is closed when a predetermined number of game balls have been won in the variable winning means 15 and the game balls won during the opening pass the specific area 25. And has a function of controlling to continue the opening and closing operation.
[0024]
The jackpot determination value switching means 36 is for switching and changing the jackpot determination value in the jackpot random number by random number processing when a predetermined condition set in advance is satisfied. The jackpot determination value switching means 36 includes a determination value switching counter 39 that counts a switching random number equal to or less than the number of random numbers 1 to 401 of the jackpot random number. The switching random number value counted by the determination value switching counter 39 is updated to the jackpot determination value of the jackpot determination means 38 with the end as a trigger. This update can also be triggered by the acquisition of the jackpot determination value.
[0025]
As shown in FIG. 4, the judgment value switching counter 39 uses the program that the game control means 26 repeats the program processing in accordance with the game control program every one interrupt time T. The count value is updated within the remaining time t from the end of the process to the start of the next program process.
[0026]
Next, the operation of the above-mentioned bullet ball game machine will be described. When the launching handle 10 of the launching means 9 is operated while there is a game ball on the upper plate 7, the game balls of the upper plate 7 are supplied one by one to the launching unit in conjunction with the launching operation of the launching means 9, and the game ball Is fired with a striking gutter and fired sequentially along the guide rail 11 toward the game board 4 side.
[0027]
When the game ball launched on the upper side of the game board 4 falls along the board surface of the game board 4 and the game ball passes through the second symbol starter 16, the second symbol variation control means 31 works. The second symbol of the second symbol variation display means 22 is varied for a predetermined time. On the other hand, when the second symbol starting means 16 detects a game ball, the hit determination processing means 30 extracts a random number value of the hit random number and makes a hit determination based on whether or not it is a hit determination value. 2 Stop the design change display means 22 so that the stop design displays a predetermined winning design.
[0028]
When the stop symbol of the second symbol variation display means 22 becomes a winning symbol, the opening / closing control means 32 operates to open the pair of opening / closing claws 23 of the first symbol starting means 14. For this reason, it is easy for a game ball to win the first symbol starting means 14, and the first symbol of the first symbol variation display means 21 is likely to change accordingly.
[0029]
When the opening / closing claw 23 of the first symbol starting means 14 is opened and a game ball wins, the first symbol variation control means 34 operates to similarly change the first symbol of the first symbol variation display means 21 for a predetermined time. On the other hand, when a game ball wins the first symbol starting means 14, the jackpot determination processing means 33 performs the jackpot determination processing, and whether or not to stop the first symbol at the jackpot symbol after the first symbol variation display means 21 changes. Determine.
[0030]
That is, in the jackpot determination processing means 33, every time the program processing of the game control program of the entire game control means 26 is completed, the jackpot random number counter 37 counts and counts each random number value from 1 to 401 of the jackpot random number. When the first symbol starting means 14 detects the winning of the game ball, the big hit determining means 38 extracts the random value of the big hit random number at that time. If the random number value of the jackpot random number is, for example, the jackpot determination value 75, the jackpot determination means 38 determines that the jackpot is won, and the first symbol fluctuation control means 34 works to change each symbol after the fluctuation of the first symbol fluctuation display means 21. Stops at a predetermined jackpot symbol such as “7, 7, 7”.
[0031]
When the stop symbol of the first symbol variation display means 21 displays a jackpot symbol, the special prize giving means 35 operates to drive the variable winning means 15 to the first state in which the open / close plate 24 opens to the front side. Therefore, many of the game balls falling from the upper side of the game board 4 can easily win the variable winning means 15 via the opening / closing plate 24. When a game ball wins the variable winning means 15, the payout control means operates the payout means, and 15 prize balls are paid out for each winning ball. Therefore, once a big hit occurs on the first symbol variation display means 21 side, a great profit is returned to the player.
[0032]
The variable winning means 15 closes the opening / closing plate 24 when ten game balls are won or when a predetermined time has elapsed. If a game ball won while the opening / closing plate 24 is opened passes through the specific area 25, the variable winning means 15 is opened again and the opening / closing operation is repeated up to 16 times.
[0033]
In the game control means 26, as shown in FIG. 4, the program processing within one interruption time T 2 is repeatedly performed at a constant cycle in accordance with the game control program stored in the ROM. In the jackpot determination processing means 33, the jackpot random number counter 37 sequentially counts in the ascending order for each program processing, and repeats the counting operation from 1 to 401. The detection signal from the first symbol starting means 14 , And whether or not the random number value at that time is the jackpot determination value 75 is determined to perform the jackpot determination process.
[0034]
In the jackpot determination value switching means 36, the determination value switching counter 39 sequentially counts in the ascending direction at the remaining time t of one interrupt time T every time the program processing is completed, and repeats the counting operation from 1 to 401. . Then, when the special prize is given by the special prize granting means 35, the jackpot judgment value switching means 36 extracts the switching random number value of the judgment value switching counter 39 at the time when the special prize grant is finished, and the switching random value The jackpot determination value of the jackpot determination means 38 is updated. For example, if the switching random number value is 350, the jackpot determination value of the jackpot determination means 38 is updated to this random number value, so that the jackpot determination means 38 performs a determination operation with the jackpot determination value as 350.
[0035]
Accordingly, if a special prize is given by the special prize granting means 35, every time the special prize grant is completed, the jackpot judgment value switching means 36 adds the jackpot judgment value of the jackpot judgment means 38 to the random value of the judgment value switching counter 39. Since switching is performed, the jackpot determination value of the jackpot determination unit 38 can be changed every time a special prize is awarded by the special prize granting unit 35. For this reason, the jackpot determination value of the jackpot determination means 38 changes irregularly every time a special prize is awarded, and the periodicity of the jackpot determination value is lost. Therefore, the timing of the jackpot determination value is simply synchronized with the generation period of the jackpot random number. It is not possible to mislead the jackpot by grasping
[0036]
In addition, the judgment value switching counter 39 of the jackpot judgment value switching means 36 performs update processing following the program processing for the remaining time t in one interruption time T of the game control program. Since the time changes, the remaining time t 1 changes, and the number of times the random number value is updated becomes indefinite, so that the switching random number value can be changed irregularly.
[0037]
FIG. 5 illustrates a second embodiment of the present invention, in which the jackpot determination value switching means 36 is operated according to a specific losing lottery result drawn by the lottery game function to switch the jackpot determination value of the jackpot determination means 38. It is a thing.
[0038]
That is, the jackpot determination value switching means 36 includes a specific outnumber random value extraction means 40 for extracting a preset outnumber random number value from among the big hit random numbers in the big number random number counter 37, and this specific outnumber random value extraction means When 40 extracts a specific out-of-range random value, the random value of the judgment value switching counter 39 is updated as the jackpot judgment value of the jackpot judgment means 38.
[0039]
Therefore, also in this case, the jackpot determination value of the jackpot determination means 38 can be changed irregularly. Also, if a large number of random numbers are set as unspecified random numbers in the out-of-specific random number extraction means 40, the jackpot determination value changes every time those random numbers are extracted, so that the big hit determination value can be changed frequently.
[0040]
In the embodiment, the following inventions are described. The first is that a plurality of types of winning means 14, 15, 17-19 are provided in the game area 12 of the game board 4, and among the plurality of types of winning means 14, 15, 17-19, to a specific winning means 14 A lottery game function that operates by random number processing on the condition of winning a game ball, and when the lottery game lottery value drawn by the lottery game function is a special prize judgment value, the lottery game results In the ball game machine provided with a special prize granting function for giving an advantageous state, a special prize judgment value switching means 36 for switching a special prize judgment value according to a preset condition among the special lottery random numbers for the lottery game is provided. Is.
