My counter adds 1 but doesn't update properly - vb.net

Question

This is a slot machine program. I am trying to detect how many times the user clicks a button (spins). But I can't figure out why my counter only adding 1 to my clickLabel? I'm sure it's a simple fix but I'm drawing a blank.
Public Class MainForm
Private Sub clickHereButton_Click(sender As Object, e As EventArgs) Handles clickHereButton.Click
' simulates a slot machine
Dim randGen As New Random
Dim leftIndex As Integer
Dim centerIndex As Integer
Dim rightIndex As Integer
Dim counter As Integer = 1
clickHereButton.Enabled = False
For spins As Integer = 1 To 10
leftIndex = randGen.Next(0, 6)
leftPictureBox.Image = ImageList1.Images.Item(leftIndex)
Me.Refresh()
System.Threading.Thread.Sleep(50)
centerIndex = randGen.Next(0, 6)
centerPictureBox.Image = ImageList1.Images.Item(centerIndex)
Me.Refresh()
System.Threading.Thread.Sleep(50)
rightIndex = randGen.Next(0, 6)
rightPictureBox.Image = ImageList1.Images.Item(rightIndex)
Me.Refresh()
System.Threading.Thread.Sleep(50)
Next spins
If leftIndex = centerIndex AndAlso
leftIndex = rightIndex Then
MessageBox.Show("Congratulations!", "Winner", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
counter += 1
clickLabel.Text = counter.ToString()
clickHereButton.Enabled = True
clickHereButton.Focus()
End Sub
Private Sub exitButton_Click(sender As Object, e As EventArgs) Handles exitButton.Click
Me.Close()
End Sub
End Class

What's happening is you're always setting the counter to 1 everytime you click the button because it is inside the clickHereButton_Click. So even though you are incrementing it, at the beginning of your sub you are still setting it to 1.
Dim counter As Integer = 1
Private Sub clickHereButton_Click(sender As Object, e As EventArgs) Handles clickHereButton.Click
...
End Sub
