No, it is not rigged.

Because rigged implies that they, in any way, presented them as equally likely. This isn't the case, because it would be ridiculous given the best prize on the board.

This makes it not fair, but it is not rigged. Those are two different things. Something that is not presented as and is actually not "fair" is not rigged.

Anyone who would expect them to be equal chance is, to put nicely, overly and naively optimistic.

An argument can be made for the group wheel to be rigged. As the prize on there are not of unreasonable value to be fair. And therefore, lacking reasons to the contrary, could be believed to be fair. And as far as result goes, it does not appear to be fair. If something appears to be but isn't fair, then it is rigged.

On another note, Lucky Board seems "fair". I haven't tracked every single dice throw (I usually throw in 10s anyway) but I get more or less everything evenly I think.

Ah yes, TI card flip is rigged, it does nothing, your reward is determined before the actual flip

Some theorize the same thing for survival breakthrough.

That said, there is a chance that while rigged, they are fair, that is to say you are equally likely to get what is presented anyway. But it might not be, whoever knows~

Edit: on second thought, if it is fair, then it is not rigged.

Rigged requires two components:

1. It is not what it appears to be

2. It is advantageous for one party and/or disadvantageous for the other.

If it's fake but fair, then it fulfills 1 but not 2, thus not actually "rigged"....

do we have a word for that?
