One might wonder what it is that makes a great online casino slot game. There are many slot games available at online casinos, and while it is likely that all of them are played, there are always those online casino slot games that are more popular than others. While online casino software companies do get used to what players like and will cater to their players and various groups of players, there have been those who say that the choice of slot games is one of psychology, and that there is a reason that players will keep returning to specific online casino slot games while they simply disregard the many others that are on offer.
Charles Fey, the inventor of the Liberty Bell slot machine in 1895, which was the first mechanical slot machine, seemed to get it right. Not only was the idea of a slot machine an excellent and fun idea, but the symbols he chose to use were all familiar to players and it seems that this was an added bonus. Choosing symbols that were well known and instantly recognized by players made people feel comfortable with the game before they began to play. The symbols that were first used on the first three reel slot game were the hearts, diamonds, and spades from cards, and also the cracked Liberty Bell image.
Although slots have gone through many changes over the years, it still seems that the same idea applies. Players will go for slot games that they recognize and that are familiar. Players will of course try other slot games, but the most popular online casino slot games always seem to be those that have familiar themes and graphics. Some online casinos list which slots are the most popular at the time, and the slots that are the most popular are those that have familiar themes, like branded online casino slot games, from superheroes to board games, and of course slots with movie themes.
Interestingly, a chartered psychologist from Nottingham Trent University, Dr. Mark Griffiths, who was associated with the university's International Gaming Research Unit, noted that when he first did research into slot games more than 25 years ago, the games that were most popular were those online casino slot games that reminded players of ways to receive money. These games included Cash Point, Action Bank, Piggy Bank, and Money Bank. The association with objects that gave out money was a good attraction. Later, players found other things that were familiar to them that they could relate to.
