The following might be useful. Based on what you have written, you are playing
"high variance" slots. If you want to stretch your gaming experience,
you should play "low variance" slots.
"Low variance" slots refer to games where the gap between 3/4 of a
kind to 5 of a kind is small. An average gap of 3 to 5 in the payout table
would give you a low variance slot.
"High variance" slots refer to games where the gap between 3/4 of a
kind to 5 of a kind is large. An average gap of more than 10 would be a high
variance slot.
In general, slots with progressive jackpots have a higher variance than an
equivalent slot wihout a progessive jackpot (e.g. Kia's 5Koi that is not linked
to the progessive jackpot).
On the expected return, CRA mandates a minimum of 90%. No casino in the world
however programs slots with such a poor return. This is because the loss would
be so fast and devastating, no one would ever come back to play.
In general, 93% to 97% is the most common expected return for slots in order for
them to be commercially viable. Given all the slots are now linked via wireless
network, it is quite easy to have an application to vary the return at
different times. Since these are well above 90%, there is no running afoul of
CRA regulations.
The casinos vigorously deny doing this and say that this is a conspriacy theory.
However examing the patents filed by big slots makers like IGT reveals that
they have patented technologies that do just this. If the casinos were not
buying and deploying this capability, why would they be doing so much work and
patenting this?
Good advice therefore is to avoid crowded periods like CNY where almost everyone
seems to have lost $$$.

For the uninitiated, the word "variance" in this context equates to
the word "risk", or put simply, a low variance slot machine is
basically a "low risk" slot machine. The risk element however does
not affect the expected payout. Most of the video slots featured here at
SlotJunkies have an expected return between 93% and 97% and whether they are
"low variance" or "high variance" doesn't affect that one
bit. What the slots variance does affect is how the slot game pays you and this
has a knock-on effect which should dictate how much you bet on a spin, how
large a bankroll you need and how soon you are likely to run out of money! It
helps to have a good slot strategy in place before you play!
In simple terms, a low variance slot will pay you a combination of half decent
and "token gesture" wins more often, while a high variance slot will
give you mainly token gesture wins and very occassionally a monster! There is
of course some middle ground. How do you tell if a slot is low, medium or high
variance? Well, the only way is to play - or use this site - and while the
paytable can sometimes give you some clues, it's not a decisive indicator. Most
casino software providers don't publish the variance rating of their online
slots either, which is a shame. IGT slots are the exception to the rule and
from their data we can see that most of their slot games fall between 93% and
96%.
If you look at the paytable of most online video slots you often get a hint at
the variance. If you see, for example, that 3 or 4 of a kind pays out
relatively low, while 5 of a kind seems to be a lot more (perhaps 10 times more
than 4 of a kind), the chances are you are looking a high variance slot. If the
gap between 3, 4 and 5 of a kind tends to be in 3-5x range of it's lower paying
cousin, then you're possibly leaning more toward a lower/medium variance. But
this is not decisive - a lot depends on how many symbols there are on a reel,
whether there is a jackpot on the slot or how many paylines the slot has.
Having played the majority of online slots, I have added a rough indicator of
the slot variance for every game to Slot Junkies [.net]. It's not a bible, but
it does give a pretty good indicator. Once you have got a feel for the variance
of a given game, the most important thing is that you balance your betsize
accordingly. A failure to do this could mean that you run out of money before
you hit a decent win. Players that don't understand this concept are more
likely to feel that a slot game is rigged, whereas none of the casinos using
the top software and listed here at Slot Junkies have the ability, or facility,
to rig games. Every slot has it's bad streaks and variance plays a decisive
role.
