We were careful not to break the law. You were running computer simulations. So as your Blackjack players would be comfortable and not dazzled by a casino environment.

At the end of the day, we made the money to do everything the well-known card-comitant techniques have already been written about. But we did it more diligently. I think running simulations to predict how much it should have won in order to kind of track what really happened. Then running these examinations basically where in our own classroom environment,. We would try to distract people.
