Very interesting.
tiny defects — chips, dents, scratches, unlevel surfaces — might cause certain wheels to land on certain numbers more frequently than randomocity prescribe
California's casino laws finally make sense to me why they probably do what they do. In California craps and roulette you still roll dice and spin the ball on the wheel, but the resulting die value or hit number then cause different cards to be flipped over to determine the outcome of the round. This removes the imperfections from the tables, dice, wheels and balls from having as significant of a direct effect on the outcome.
Interesting.
Weird it too the casino so long to replace the wheels. Whatever the cost it had to be less than what they were losing.
