Yeah let me go ahead and spell out that vulnerability on a public forum that gets regularly analyzed by casino personnel ;)
Sometimes the dice lean up against the glass so that the outcome of the roll can't be determined by the unit. You can imagine the complaints when that undetected roll appears to most likely be the point and/or hardway. My guess is a dip in the middle of the platform reduces the number of undetermined rolls.
PS real table craps can be beaten. Ask mustangsally
Just speculating about a vulnerability...
The dice don’t always roll when the “tingler” is activated. This means one or both will be tossed straight up, rather than at an angle. I think this is akin to a Craps table toss failing to hit the back wall.
Either way its somewhat moot if aruze is pulling the old versions
They aren't pulling all of them though. One casino in Vegas, for example, has two of these machines. One is flat, the other isn't. There are several in other jurisdictions that are still flat as well. Maybe they're offering it to casinos as an optional enhancement.
Then that should answer your question as to whether this design change was due to suspected AP vulnerability. No way do they go to that trouble and then fail to replace all the machines
Since you have seen some old and new side by side i would theorize they have changed the design for aesthetic purposes and are replacing machines as needed. Similar to how trains on a subway line have older models fazed out as they are replaced by newer models so u see first a mixture and then eventually nothing but the newer model
