Online casinos always have very similar games of blackjack and roulette although one or two do try to bring in some variations that you will never find in a land based casino but in the area of casino slots there is an enormous variation waiting for you. Some online casinos try to differentiate between video slots and normal slots although they are all either 5 reel or 3 reel slots at the end of the day. Online casino slots have come a long way since the original fruit machines which incidentally were originally the flavours of the chewing gum that you won as a prize long before cash payouts were legal but you can still play these 3 reel one win line slots at a good online casino and they are certainly much easier to understand and follow than some of the 5 reel slots of today that have multiple win lines. What really gives the differentiation between the online casino slots of today is the theme of the slot which runs through the symbols on the reels as well as the music which accompanies it and probably the most popular are those casino slots that use some of the better known comic book characters and it is often these slots that offer the massive progressive jackpots which can and do run into the millions of Euro. Other casino slots are those with smaller jackpots which have an element of fun such as Gonzos Quest which can be found at All Irish Casino with Gonzo being an explorer who will dance a jig for you when you hit a decent win. Most online casinos have a huge choice of casino slots so really the choice is down to the individual to decide what stakes to play for, bearing in mind that more winning lines means an increased stake and of course whether to go for the really large jackpot or a smaller one which has a better chance of being won.
