Whilst many online casino games have had the same layout and rules for many years, in the world of online casino slots nothing could be farther from the truth. Whilst the roulette wheel continues to spin, albeit taken over by a random number generator in online casinos, the old mechanical three reel one armed bandit is a thing of the past as modern electronics have caused something of a revolution. Today’s slot machine have multiple reels and winning lines that zig zag all over the shop making it nigh on impossible for the player to figure out whether they have a winning line or not; some offer 5 reels and up to 5 visible symbols on each reel which for the mathematicians amongst you creates 3125 possible combinations and if there are 100 winning lines it could take a very long time to check. Just as well therefore that you don’t have to as the machine electronics will do it for you. This might be an extreme but even the more popular online casino slots will often have 5 reels and 3 visible symbols per reel giving 81 possibilities and with an average of between 15 and 25 winning lines it would still be a very slow game if you had to check it yourself. There is of course always the opportunity to ask the machine to show the winning lines one by one which is a good thing to do if the machine is new to you. Perhaps the greatest number of winning lines is offered on the Ladbrokes Arctic Fortune slot which has no less than 1024 which betting at €1 cent per line will cost €10.24 per spin but with 4 symbols per reel on the 5 reel machine winning lines are created frequently. Another reason to play online casino slots is the massive jackpots that are available often running into the millions of euro; give them a go and the best of luck..
