Risk Less - Play Longer
One strategy you can take is to try to spend as much time
                      as possible on the slots, to keep your hope and fun alive
                      as long as possible. You last forever at the slots when
                      you make the amount of money you start with last as long
                      as possible. To do that, start with the lowest coin size
                      and only switch to a higher coin amount if you are winning.
                      The longer you can play without risking any additional
                      money of your own, the better your chance that you will
                      line up that winning combination for a big payout. 
Play the right machine
When trying to decide which online slot machine you should spend your
				      time with, consider the size of your bankroll and your
				      priorities. If you are hoping for a very sizeable jackpot,
				      make it a progressive machine. If you'd rather play for
				      a longer period of time and would be happy with a modest
				      win, then find an online slot machine with a relatively
				      small jackpot, but with a paytable that offers a good range
				      of small to medium payouts. Look for machines with good payout rates,
				      few lines and a good coin range.
How much money?
Decide in advance how much money you are going to invest for a particular
				      session, and stick to that limit. Don't get carried away, hoping that
				      if you make another deposit your luck will turn and you will recover
				      all of your losses. It's one of the traps casinos hope you'll fall
				      into. Select an online slot machine where you can change the coin size
				      with a click of your mouse. If things don't go right, switch to a lower
				      coin size. Make your money last and sooner or later a win will come. 
Go for the jackpot
Most slots pay a higher top jackpot for maximum coin play. For example,
				      a three-coin machine might pay 300 coins for 1 coin, 600 coins for
				      2 coins and 1,200 coins if three coins are bet. In this case and on
				      all progressive slots it is very important to play the maximum number
				      of coins. 
If you do not want to play maximum coins, I recommend that you, either
				      look for a slot machine that does not pay a bonus for maximum coins,
				      or reduce the coin denomination so that playing maximum coins is not
				      that expensive. With a bit of luck you will soon experience the thrill
				      of collecting your first online slot machine jackpot!
