This is a slot machine that resembles the real slot machines in the casinos. To create the project, you need to insert three image boxes into the form and program them so that they will display a set of three different pictures randomly when the user presses on the spin button. It involves a randomization process. Next, a timer needs to be incorporated into the procedures so that the program can produce animated effects. In addition, you can also insert the Microsoft Multimedia Control so that it can play sounds in synchronization with the spinning of the slot machine as well as when the player hits the jackpot. You can design any interface you like. We have created an interface as shown below:
The Interface
The Video Demo
The Code for Spin Sub Procedure
The three random variables a, b and c will be randomly assigned the values 1, 2 and 3 using the RND function. Based on these three random numbers, three different pictures will be loaded into the three image boxes randomly using the LoadPicture method. Animated effects are created by putting the above procedure under the control of Timer1, which will call the spin procedure after every interval until it fulfills a certain condition. Sounds are also added using the Microsoft Multimedia Control to make the game more realistic and interesting. The amount won is controlled by the If...Then...End If statements
It is important that you define the correct path for the LoadPicture method, otherwise the program will not be able to run. For example, our path is C:VB programImagesgrape.gif, you need to create the necessary folders and have the necessary image file if you wish to copy the program directly. If you place the image file in a differently folder, you need to modify the path accordingly. For example, if your image file is in D:VB programImagesgrape.gif, then you need to modify the LoadPicture method to LoadPicture('D:VB programImagesgrape.gif').
If you wish to use our image files, you can download from the links below:
sound and the other for the jackpot sound. Below is the video demo of the slot machine simulator.

The problem
A slot machine is a gambling device that the user inserts money into and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money that the slot machine dispenses back to the user.
Create a program that simulates a slot machine. When the program runs, it should do the following:
- Ask the user to enter the amount of money he or she wants to enter into the slot machine.
- Instead of displaying images, the program will randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars
- To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries; if the number is 1, the selected word is Oranges; and so forth. The program should randomly select a word from the list three times and display all three of the words.
- If none of the randomly selected words match, the program will inform the user that he or she has won $0.
- If two of the words match, the program will inform the user that he or she was won two times the amount entered.
- If three of the words match, the program will inform the user that he or she has won three times the amount entered.
- The program will ask whether the user wants to play again. If so, these steps are repeated. If not, the program displays the total amount of money entered into the slot machine and the total amount won.

- Enhance output to look like a real slot machine.
- Enhance getReal to be more efficient.
- Create an ENUM to represent reel type and change parameter type to method getReel.
- What changes would need to be made to play a slot machine with 4 reels?
- Determine the algorithim flaw with the output.
