Although certainly not the oldest form of gambling game, the slot machines were undoubtedly the first experience of playing what we now call a casino game for many of us today. Slot machines have come a long way since the penny arcades which could be found on almost every seaside pier, and many of them now offer a multitude of choices to follow a winning set of numbers or symbols making them significantly more complicated than the first machines. However it appears that we still love to play any form of slots game and the online casinos have of course recognised that in a big way. All the online casinos offer a huge range of casino games for us to enjoy, but the number of slots games on every online casino site far exceeds any of the traditional casino games available, and it is clear that most new online casino games players prefer the slots games to any other casino game. Many of the slots games we can now play online bear little or no resemblance to the slot machines of old, or indeed the modern slot machines we still play in the pubs and clubs. The online casino slots games are now mostly designed by specialist casino software companies and are often based on well-known television programmes, films or cartoon characters. In fact the range of themes which the online casino operators use for their slots games is now so extensive that almost everybody will find a casino slots game which appeals to their individual taste. That is of course one of the reasons why the online casino slots games have proved so popular, but it is also true that digital technology has enabled the designers to develop slots games which remain easy to play but offer a wide range of new ideas. Many now feature as many as five reels with multiple winning lines on each spin. The All Irish casino even has a slots game which uses falling blocks instead of the traditional reels, and new slots games continue to be introduced all the time.
