This really does seem like a crazy one to me, it's either incompetence or corruption on the part of BFM (as indeed are all these things). On the one hand it seems almost unbelievable that they didn't see the problem with a game design of 'infinite hi-lo gambles' on a complex hi-tech machine with loads of mechanics available to cheese the gamble when the machine finally sees the risk.
Or maybe they did see the problem and punted it out there, knowing what would happen and that a load of players would make bank, before they dialled it in with a rechip, and knowing full well that there would be no consequences.
Depending on who you listen to these things are all accidents, or they're sometimes accidents and sometimes corruption.
Yes I did this method in the video as it was chipped out early doors on £70 and I'd lay money on them being none out there in the wild, unchipped, on £70.
I've had the £100 trap explained to me a couple of different ways, including one that still works on £100 chip Perfects that are out there now, but I wouldn't do that in a video.
