押せたらすぐ
NO BINGO: 8284552 (82.8455%)
BINGO: 1710841 (17.1084%)
SUPER BINGO: 4607 (0.0461%)

BINGO: 1796909 (17.9691%)
SUPER BINGO: 4860 (0.0486%)
部屋毎の期待値もシミュレートしてみた
パネルとボールの変異が逆転してるけど多分理論上は同じ
20人部屋 期待値約1.1倍＋SB期待値約0.36倍(MAX BET時)
NO BINGO: 8283840 (82.8384%)
10x BINGO: 692406 (6.9241%)
5x BINGO: 630924 (6.3092%)
3x BINGO: 322916 (3.2292%)
2x BINGO: 65091 (0.6509%)
0x BINGO: 4717 (0.0472%)
SUPER BINGO: 4702 (0.0470%)
10人部屋 期待値約1.33倍＋SB期待値約0.36倍(MAX BET時)
NO BINGO: 8283393 (82.8339%)
10x BINGO: 1033286 (10.3329%)
5x BINGO: 547034 (5.4703%)
3x BINGO: 125915 (1.2592%)
2x BINGO: 10119 (0.1012%)
0x BINGO: 251 (0.0025%)

2x BINGO: 641 (0.0064%)
0x BINGO: 6 (0.0001%)
SUPER BINGO: 4718 (0.0472%)
いやーきついっす
ていうかSB率って0.0458％とかよく引けたなおい！二回目を引けるイメージがねぇぞ！
そしてチャンスボールのタイミングは誤差レベルじゃねぇか！！！
さて期待値が1以上であることがわかったので仕事しながらビンゴに帰るか（白目を剥きながら）
この全然面白くない作業苦行のくせに大事すぎるクソコンテンツなんとかしろやHRTァ！！！！
おまけ、20人部屋時のフリーボール数による勝率
6個
NO BINGO: 747285 (74.7285%)
10x BINGO: 107912 (10.7912%)

10x BINGO: 63843 (6.3843%)
5x BINGO: 60751 (6.0751%)
3x BINGO: 31550 (3.1550%)
2x BINGO: 6460 (0.6460%)

0x BINGO: 306 (0.0306%)
SUPER BINGO: 338 (0.0338%)
4個引いただけで絶望だな！
最後までやると1分20秒かかるけど3個めで上がると40秒。1分計算だと2200分＝36時間プレイでSB期待値だぞ！やったな！
