Let's say you frequent a local casino several times a week, grinding
out a modest little edge at one of their 25 cent 100%+ machines. The
casino has several of these machines spread throughout the casino but
you happen to like maybe just one machine because it's less smoky or
noisy in that area. Do casinos keep track of a win/loss record for
each machine, and is it wise to maybe spread out your play over the
same machines throughout the casino? Can hammering out an edge on only
one machine kill that particular machine?
