Specialize, find machines that you understand and play them.
Don't play just any machine. Learn what machines appeal to you and stick
with them, we all have favourites that's part of the fun.
Take a chance, if you are up you can afford to take a chance
on high end machines even the 5.00 slots. If you do get a hit...run.
Read the machine, make sure you understand the payoff schedule on any
slot you play, you will avoid disappointment. Once you have done this
you will avoid certain machines.
One coin play, you don't need to play three coins at all times,
particularly on high end machines, $1.00 $5.00 and up. Find machines
that will allow one coin play and still payout the maximum. I am not
talking about pay for play type machines nor three or five liners. I
am talking about single line machines that payout on all symbols for
1 coin. You will sometimes think, gee if I had played three coins I
would have won three times as much, beware the Casinos main weapon....
Greed.
Set your own rules, because a machine takes up to 5 plus coins
does not mean you have to play that many. If you read the machine you
will see, in many cases, that the payout per coin is exactly the same
relative value. In other words many slots will pay X for 1 coin and
2X for 2 coins and 3X for 3 coins.
Read the machine cycles, this one is still up for grabs but
my experience says that slots pay-off in cycles. They go through a "take"
cycle and they go through a "pay"cycle. Needless to say the "take" cycle
lasts much longer than the "pay" cycle.
