The best chance of winning big money for a relatively small outlay at an online casino is in the casino slots section and at most online casinos there are literally hundreds to choose from which can make selection difficult. One of the most important things to decide when playing casino slots is whether you are chasing the really large progressive jackpots worth millions of Euro or whether you are simply having fun and wanting to win a nominal amount. For the really big online casino slots jackpots you will need to be playing one of the 5 reel slots which have progressive jackpots attached and these are usually clearly labelled but remember that to win the large slots jackpots you will probably need to be playing for the maximum stake per line that the slots allows and most will also play for the maximum number of lines although that is not necessary to win the jackpot, it merely increases your chances. If on the other hand you are playing online casino slots more for pleasure there are a number of low cost per line slots available and some of the best can be found at All Irish Casino where the casino software supplier Amatic Industries has a number of simple 3 reel slots as well as relatively simple 5 reel slots. All Irish Casino also has a full range of video slots with some impressive jackpots available. The decision about which of the many online casino slots to play basically comes down to personal preference of the graphics and sometimes the theme but casinos.ie really likes Gonzos Quest where wins can be multiplied or Jack Hammer where the slot includes what are known as sticky wins whereby a win is held and the remaining reels spun with no additional cost to see if the win can be bettered.
