Added a translation note because I completely forgot that 30mm was the maximum bet until I rewatched a few episodes. Dang, that really is putting everything on the line...
My bet is... Astonishing! A great bleeding service! I'm always putting everything on the line!President...! President Hyoudou...!Why am I fighting her...!?Really...?The one who finished the Steel Beam Crossing was Kaiji, right!?Hm? Hmmmmm?Well, it's fine.Guh...The president too... Is she controlling him...!?Ah, I don't mind too.No... I feel like this stupid old man was always like this too...Overwhelming UncleTch... Whatever...!This isn't the first time the president just did as he wished...!Plus... Now that I think about it...30 milimeters!
Instead of betting money, one of the players bets on the distance that the device on their ear will drill into, and once it reaches 30mm deep it will pierce their eardrums and leave them deaf. Even if you don't bet the whole 30mm right away, just hearing a drill inch closer and closer to your eardrum would be a horrifying experience. Just imagine it! Or watch Kaiji.
