The evolution of the slot machine industry from computerized machines to video slots and the increasing popularity of online casinos and mobile gambling opened up a world of opportunity for game designers to develop new types of gaming routines. In this new setting, an increased, even unlimited, potential for player interaction emerges. Game designers have to embrace change and develop innovative games that make the most of it. Interesting game ideas are needed that will interest the players by offering new and interesting possibilities, but not too new and different slot gacor so that the players are alienated. Success in attracting the attention and interest of players is important because of the size of the industry. In the UK, for example, gambling makes a significant contribution to the economy with an estimated expenditure of £8.875 million (0.8% of UK GDP (Gambling Act, 2005)), of which £1.74 billion is generated from customer losses by playing slot machines. (Board Games, 2005).
Slot machine games require a suitable mathematical model to ensure the game is profitable and to accurately calculate the minimum house edge. In games where players have input, the player’s optimal strategy must be calculated to calculate the minimum house edge. Probability, Operational Research and Stochastic Process techniques were used to build this model. Good programming skills are also required. If video slots allow games to be more interactive, they can become more sophisticated and, consequently, more difficult to model. This is a specialized job that only trained professionals can do.
