I understand variance. I know that sometimes you see seven roll at craps twice in a row even though you can't expect that, and I know I've seen some weird things like 12 rolling three times in a row, or a single hand of craps that lasted an hour and five minutes. If you don't play craps, that means anybody that made place bets (4, 5, 6, 8, 9, 10) had all winners, and no losers, for over an hour! Amazing. Based on that, you'd think that manufacturers would be happy with the variance and the unpredictable nature of gambling without having to take extra steps to enhance player confusion. Nope, think again.
If you've read my blogs and columns, you know I play a lot of roulette, too. In France you'll find most games have a single zero, and the clubs accept announce and call bets, but I'm not in France too often, so I'll play double zero wheels, I'll even play electronic versions of roulette when there is an actual wheel and spinning ball. The problem is that I'm always looking for patters and regularity. Live dealers often deal with great reliability, they'll muck the chips for thirty seconds, spin the wheel and get a very reliable number of revolutions (usually about 30 or so), finish mucking the chips, and then wave off any more bets and mark the winner. That's what I like.
Unfortunately, almost all electronic wheels are now designed to have variance in the number of spins. A puff of air sends the ball spinning, and the pressure changes so the puff is different all the time. Bummer, as I often say. My wife says acceptance is a virtue. Guess this is another thing I have to accept - because I can't change it. Anyway, those of you who are clocking the electronic wheel or looking for patterns, well, let me know if that ever works! Good luck.
