13.1.1 Problem Definition A slot machine is a casino-style game in which a player deposits a coin and pulls a lever, causing a set of wheels to begin spinning. Each wheel has a number of digits or images painted around its circumference, which are displayed through a window. After the pull lever is released, the wheels freeze, each displaying one digit/image, If the displayed numbers/images match one of a set of specified patterns, a designated amount of money is won. The payof, or the amount of money won, depends on the pattern matched and in some cases may also be a function of the amount of money deposited (or wagered) There are a number of variations of this game, including hand-held elec- tronic games that utilize no money. These operate by simply pulling a lever or pressing a button to initiate rolling and freezing of the number wheels To minimize mechanical parts, an electronic display is often used to simulate rolling wheels by ciuously changing the digits being displayed. Winning combinations are signaled by blinking lights and/or audible alarms. In some cases points are won and lost, allowing players to keep unning scores while playing the game. In this example, we will design an electronic slot machine game that is operated by depressing a push-button PLAY switch, causing numeric digits in the range[17] to be continuously displayed and changed on an electronic display panel in such a way as to give the appearance of rotating number wheels. The digits will freeze on the display after the PLAY button is released. If one ofa specified set of numbers is displayed, a payoff, a designated number of points, will be digits will be designated as winners, with three identical digits returning a bigger payoff (more points) than two identical digits. The size of the payoff will also be a function of the value of the matching digit and a wager, which will be placed using two switches prior to pressing the PLAY button. Figure 13.1 shows the basic layout of the front panel of the game. awarded. In our machine, any combination of two or three identical

Explanation / Answer

There is given an electronic circuit that needs to be driven by random data generation framework. When the user depresses the PLAY switch, the processor of this structure is organized to peruse a grid of changes to decide a limit of numbers and to set up a product controlled sequencing routine comparing to this limit. The interrupt terminal of the electronic circuit is utilized to detect the actuation of the framework and causes the number choice. If there is no control on the limit of number, then the machine could generate the random number out of the given range [1…7]. On the contrary, if the machine is desired to operate for a limited range then the prewritten software code rearrange the counters to the designated value of a number and rerun the random sequence generator to that specific number.
