And thus we now know what the cancer killing this board is

It baffles me that slot machines didn't immediately use noise generators, from the get-go. Those devices are so easy to make, too. And if they produce too much radio noise, you can enclose them in a faraday cage. As this sort of noise is quantum in nature, it's guaranteed to be random.

You're missing the point, Slot Machines aren't completely random by design. The house still has to win. A truly random slot machine may give payouts more often than if the randomness was instead configured within certain boundaries.

You could have true randomness without it being 50/50 probability.
Randomness just means you can't predict individual outcomes. You can still make statistical predictions if you know the underlying distribution.
So if you know the house has a 99% chance of winning, you would guess that roughly 990 of the next 1000 tries you will lose.

With pseudo randomness, you can predict outcomes if you know the algorithm used and seed number.
There is thus some hidden information that makes all the numbers generated deterministic.
With quantum randomness, there is no hidden information allowing for determining the sequence generated.

As far we know.

These experiments are all showing that there is no locally hidden variables.

You could propose some non-local hidden variables, but then you are likely hypothesizing faster than light communication of information, or wormholes or other such stuff.

I've seen them sitting on the Windows BSOD, so that answers one question.

Except that even under the copenhagen interpretation this already happens in the form of quantum entanglement. Quantum mechanics is fundamentally at odds with the strong application of the principle that causality can't travel faster than light. Since the strong version of that principle has been debunked, you can't use it to debunk things which have FTL causality but can't be used to communicate classical information FTL and thus still satisfy the weaker version of the principle.
