If you want a shot at winning anything on slot machines, you have to play. The Longshot win of someone putting a quarter in a machine and winning a million dollars is Hollywood, but it can happen. (and yes, I do put my few dollars in the giant slot machine when you enter the casino, you never know).
Apart from playing more equals more chances to win (or lose, if you look at it that way), I am a low-roller and a “session” gambler, extending play with lower wagers and $10 – $20 sessions. Winning “big” is a factor of the RNG, the “Random Number generator” that determines the outcome each time you spin. Each spin has an equal chance of winning, although larger progressive jackpots are only paid when the maximum is bet.
While I would be exuberantly happy and excited with a big jackpot, I have never won more than about $200 on any one machine. The real payout is the fun you have with a machine that has aliens, stampedes, hay-wires, super Heroes, or free spins.
So my answer is that I play, to increase the possibility of winning – but luck and the RNG have not granted the “big wins”. (YET).
Slot machine payouts are at regulated percentages over the lifetime of the machine. The machines are regulated, the payouts are calculated over the lifetime of the machine, and – unless the machine is reprogrammed – the RNG (Random Number generator) chip determines the win or lose on each wager. so the machine does not care what day of the week it is, just the RNG.
Having said that, it is obvious that some casinos have increased numbers of PLAYERS on the weekends, and more people playing means that (overall) there is a potential for more winners (and losers), although statistically the odds are the same.
There are machines that use “gaming psychology” to make you feel that winning 50 cents on a dollar bet is a “CONGRATULATIONS!! YOU WON FIFTY CENTS!!” event, when in fact you LOST fifty cents on that wager. Each wager is a random event, so gamble responsibly, understand the payout tables, and avoid superstitions like any machine is “overdue for a big win”.
Play games you enjoy, and have fun at, and walk away when you have invested an amount you are comfortable wagering. Personally, I am a “session gambler”, and will play a variety of machines when I am in a gambling mood.
I have touched on the subject before, so take a look at my shameless self promotion:
