Simple Slot Machine with Visual Basic 6

Create your own slot machine game using Visual Basic 6 with this comprehensive tutorial. Slot machines are games of chance where different outcomes appear when the player presses the play button. This guide will walk you through creating a simple slot machine that demonstrates core programming concepts.

How It Works

In this program, we create an array of nine shapes. Visual Basic automatically labels them as shape1(0), shape1(1), up to shape1(8). These shapes are arranged in three rows to simulate a slot machine interface.

Design Interface of the Slot Machine

Implementation Details

Randomness is achieved using the Rnd function. We implement a Timer control to create the animated effect of a slot machine. The timer interval is set to 10 milliseconds, making shapes change rapidly to create an animation illusion. We use a variable x to control the timer and stop it after reaching a specific value.

The Complete Code

' Start the timer when the button is clicked
Private Sub Command1_Click()
    Timer1.Enabled = True
    x = 0
End Sub

' Timer event to handle animation
Private Sub Timer1_Timer()
    x = x + 10
    Dim a, i As Integer
    For i = 0 To 8
        ' Generate random integers 0, 1, and 2
        a = Int(Rnd * 3)
        Shape1(i).Shape = a
        If a = 0 Then
            Shape1(i).FillColor = vbRed
        ElseIf a = 1 Then
            Shape1(i).FillColor = vbGreen
        Else
            Shape1(i).FillColor = vbBlue
        End If
    Next i
    
    ' Stop the timer after 500 milliseconds
    If x > 500 Then
        Timer1.Enabled = False
    End If
End Sub
