The purpose of the RNG is to randomly control exactly what percentage of winnings will be awarded in reference to how much money the online slot machines takes in.
Which brings us to the second factor...
Slot Payout Percentages:
That tiny little RNG computer chip is programmed to payout a certain percentage of the money it takes in. This percentage can rate anywhere from 80% to 98%, with some of the best payouts found in Las Vegas. As a whole, payout percentages average a 10% house advantage. For example, if a Slot Machine's RNG is set to payout 95% (a 5% house advantage), the machine will potentially payout $95,000 for every $100,000 it takes in.
I say potentially because the RNG is actually set to payout this percentage generally over it's lifetime. This means over a one-year period, a slot machine with a 95% payout may take in $1,000,000 and only payout $5,000, or .5%, but eventually over time, it will even out to 95%. In the same token, a slot machine may award back to back jackpots, say only 10 plays apart, but again it will even out over time. In the case of RNGs, Random truly means Random - the payouts will greatly fluctuate.
Slot Payout Tables:
This is possibly the most important factor in selecting a online slot machine to play. Payout tables can be very confusing if you don't understand their meaning. Players should read the entire payout table and instructions provided on or for the machine before inserting any coins. If you are unsure what the payout table is displaying, don't be afraid to ask an attendant, or in the case of online slots, contact customer support for assistance. Even if you manage to line up all the jackpot symbols, if designated requirements have not been met, your jumping and screaming won't be a joyous occasion.
Finding Loose Slots:
In order to profit from a online slot machine, players need to find the highest paying slots - preferably 98% payout. The ease of this task varies depending on where you play, a real casino or cyberspace casino. In a real casino, you may see signs claiming 98% payout, but if you look closely, the fine print usually states "on select machines" - of course the machines themselves likely won't be labeled as to which offers 98% payout. In this case, it is easiest to ask the change vendor or local players. Regular locals always know best. In online slot games, chances are the machine will list it's payout percentage. If not, ask a support rep, or find another online casino that does.
Check the Price:
Different slot games require different wagering amounts. Be sure the cost of coins you will be entering into the machine coincides with the longevity of your bankroll, as it may take some time to hit a big payout. Then compare the payout tables for each affordable slot. If a machine takes $1 coins and pays out a maximum of $500 for a single coin, and another machine takes 25-cent coins with a maximum payout of $500 for 3 coins (75-cents), the second machine is the obvious choice.
Progressive Jackpots and Bonuses:
If you choose to play progressive jackpot online slot machines, you'll want to insert the maximum number of coins. Otherwise, you won't receive the jackpot even if you line up all the symbols. Be sure to check each available progressive online slots and choose the one with the highest jackpot. But also be aware of the price. If one online slots has a jackpot of $3,576 and requires 3 $1 coins ($3 total), and another has a jackpot of $$2,941 but only requires 5 25-cent coins ($1.25 total), the second slot is the better deal.
Some Jackpots offer Bonuses when the maximum number of coins are entered. For example, if a Jackpot pays $500 for one coin, $1,000 for 2 coins and $2,500 for 3 coins, it only makes sense to play the maximum 3 coins every time. The the machine pays out on an even scale (1 coin=$500, 2 coins=$1,000, 3 coins=$1,500), there is no advantage to playing max coins, and therefore the choice is yours.
Don't Play Credits:
When a player wins on online slots, in most cases, the machine will keep the winnings and convert them to credits. This gives the player free plays in relation to the amount one. Never play the credits. Choose to take the winnings and keep them separate from your original bankroll. For example, if you're bankroll is $50 to begin with, play only from that $50. Take all won coins and keep them aside. Once the original $50is gone, add up your winnings and see how you've done. Playing them as credits causes the player to lose track of what they are spending - something casinos are counting on.
Managing Your Bankroll:
Set limits for yourself and stick to them. Whether it's a one time trip or a 7 day vacation, do not let yourself exceed the limit you have set. For multiple sessions, decide how much money you can afford to lose, divide that amount by the number sessions you will be playing, and that's your limit. For example, perhaps you plan to visit the slots twice a day on a 3 day vacation, equalling 6 sessions. You have $600 to play with. $600/6 = $100. Take only $100 with you per session. If the bankroll depletes, or if you double the amount, you're done for that session.
Don't Feed a Dead Slot:
Only play slot games that hit on average every 3 to 4 plays. If a slot runs cold, never expect it to "pick up eventually". The more time a player spends in one place, the higher the house odds become against them.
Cash-Out Before You Go:
Millions of dollars are lost every year because players forget to cash out their total winnings before leaving online slot machines. This is another reason players
should always cash out their winning coins every time they hit rather than playing them as credits. Players should also make sure they received the entire cash-out.
It is not uncommon for a slot machine's hopper to run empty before delivering the full cash out amount. Obviously online slot machines or online slots
do not have this problem, but if this happens when playing online slot games in a real casino, do not leave the machine. Call an attendant over to refill the hopper and
cash-out again to receive your remaining coins.
