Digital Slot Machine

This digital slot machine was created using Visual Basic 6. The program demonstrates how to create a simple yet engaging game with random number generation, sound effects, and visual feedback. In this implementation, you'll learn how to use the Rnd function to generate random numbers and create an interactive gaming experience.

How It Works

Random Number Generation

The slot machine uses the formula Int(Rnd * 10) to generate random digits from 0 to 9 for each slot position.

Winning Condition

Whenever a digit 7 appears in any of the three slots, a winning image is displayed and a celebratory sound effect is played.

Multimedia Control

The program uses the MMControl component to play sound effects when a winning combination occurs.

The Code

Private Sub Command1_Click()
    MMControl1.Command = "Close"
    Picture1.Visible = False
    Label1.Caption = Int(Rnd * 10)
    Label2.Caption = Int(Rnd * 10)
    Label3.Caption = Int(Rnd * 10)
    
    If (Label1.Caption = 7) Or (Label2.Caption = 7) Or (Label3.Caption = 7) Then
        Picture1.Visible = True
        MMControl1.Notify = False
        MMControl1.Wait = True
        MMControl1.Shareable = False
        MMControl1.DeviceType = "WaveAudio"
        MMControl1.FileName = "D:\Liew Folder\VB program\audio\applause.wav"
        MMControl1.Command = "Open"
        MMControl1.Command = "Play"
    End If
End Sub

Private Sub Command2_Click()
    End
End Sub

Private Sub Form_Click() 
    Label5.Visible = False 
End Sub 

Private Sub help_Click()
    Label5.Visible = True
End Sub

Key Components

Three Labels: Used to display the randomly generated digits
Slot Machine Label: Displays the game title
Command Buttons: For spinning the slots and exiting the program
Image Control: Displayed when a winning combination occurs
MMControl: For playing sound effects on winning spins

Tip: To create a more engaging slot machine, you can add animations between spins or implement different winning combinations with varying rewards.
