The statistics would bear that out and it would be caught, then the algorithms altered. It could be a short term loss, but not a long term loss.
Yeah, but why tempting the fate by precomputing the winning numbers for 10 years ahead? Nevada Gaming Control Board wouldn't be impressed.
The blockchain makes the Nevada Gaming Control Board irrelevant. I doubt they'll be impressed much at all with Bitcoin

And anyway we can change the precomputed numbers to a new set, basically re-issue new numbers. As long as it's done publicly there is no problem (old bets are valid based on those old numbers, and new bets would be valid based on the new ones).
