C# と VB.NET の質問掲示板

一応は遊ぶことは出来るのですが、表示される数字が今のままではランダムですので、スロットとしてはあまりにも使い勝手が悪く、どうすればいいのか判らず困っています。
数字の表示順を、LABELごとに固定するにはどう改良すればよろしいのでしょうか？　どうか、どなたかアドバイスをお願いいたします。
ちなみに、以下が現在のプログラムのコードです。

Public Class Form1
    Dim x, y, z, m As Integer
    Sub aaaa()
        If Timer1.Enabled = False And Timer2.Enabled = False And Timer3.Enabled = False Then
            If x = y And y = z Then
                Label4.Text = "Fever!"
                m = m + 500
                Label5.Text = m
            Else
                Label4.Text = "Boo!"
            End If
        End If
    End Sub
    Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
        Select Case Val(Label1.Text)
            Case 1
                Label1.ForeColor = Color.BlueViolet
            Case 2
                Label1.ForeColor = Color.DarkOrange
            Case 3
                Label1.ForeColor = Color.DarkGreen
