You will only find that in the older jurisdictions - it dates from a time where where digital technology was new and not quite fully understood. These days, we have a much clearer view on virtualisation, and modern regulations have much more adequately captured everything that can possibly be of influence to the customer through the principle of equivalence.
If a casino wishes to offer a card game online, how should a good jurisdiction regulate that procedure ? Should they require the casino to have an actual physical deck of cards to be shuffled in the server room and results entered ? Or should they allow a 'virtual' deck of cards - and if so how are the engineers allowed to represent that deck ? Implementation choices are infinite and so modern regulations instead of focusing on methods, focus on the result. They will all require that the result is indistinguishable from an actual deck of cards. This is how you mathematically guarantee a fair game .. if there's no mathematical way to tell the difference between the virtual and a real deck - then the virtual representation is a valid one and the virtual deck can be used instead of a real one while guaranteeing that this produces no difference for the user.
The same goes for the picking games. Should a regulator require a casino to actually have three treasure chests filled with random amounts of gold in the server room ? Obviously not - but whatever implementation the casino chooses it needs to be mathematically indistinguishable from actually having three treasure chests in the server room. Any implementation that satisfies that condition is a fair and equivalent one ..
Those older regulations that enforce that particular implementation just have rule that serves no purpose, and makes no difference. In fact the regulator himself would not be able to tell apart a machine that does from one that doesn't. It's a useless rule that protects nobody and serves no purpose. As far as ethical goes I'm afraid that that simply doesn't apply to math. It's not mathemethics - whether you like it or not, if two sides of an equation are the same - you have to put an equal sign between them. If the left side is ethical - so is the right side .. the virtualisation itself retains the 'ethical' property from the real world. What I mean is this if you take those old school and very unethical weighted b&m slot reels (with more blanks in the result than in the representation - which apparently was allowed in those jurisdictions ...) - and you make a mathematical indistinguishable virtual version of them .. then both are unethical ..
Just my 2c,

I think the point was the predetermined prize before the chest is picked. If your prize is already set before you pick a chest, the entire picking process is pointless. If a bonus round has already randomly chosen to pay 9 dollars and then asks you to pick one of three chests to receive it, there's not much excitement in picking any of the chests. Both methods may be equally fair but only one method offers excitement during the bonus round. In fact the bonus round could be just as fair to read "Pick a chest to receive your 9 dollar prize." How exciting is that?
