Staying with one machine is financial suicide! I have played slot machines
( pennies, nickles and quarters) for many years whenever I have had an opportunity to visit a casino. There aren't any here in Texas.
If I play a machine four or five times without getting anything back I leave it. If I get ahead on a machine and then play it a few more times, losing each time, I take my winnings and go somewhere else. I gamble as a minnow not a whale, but I do it for fun, and usually come out a bit ahead. Over the last 20 years or so, I am about $1000 ahead and have enjoyed myself.
