# Creating a Wheel Of Fortune with Excel

## Introduction

Excel is a very serious and powerful business application. That doesn't mean we can't have some fun with it. In this article I'll explain how I've built an Excel file which enables you to play with a wheel of fortune. With sound and all!

This is what it'll look like when we're done:

## Generating the numbers

Getting random numbers isn't hard in Excel, that is what the RAND() function is for. We'll use a two-column table. The first column contains whole numbers 1 ... 300. The second contains the =RAND() function. When we're about to do a draw, we simply sort the table on column B. This is what our table looks like (worksheet Step 1):

Worksheet Step 2 shows the prepared list of numbers, still in their 1, 2, 3 order. I've picked a rather arbitrary cell as the "drawn number cell", in this case cell A14. So after a recalc and sort, cell A14 already displays our winning number. The winner is 13. Column D will hold our previous winners.

Boring of course. We want animation!

## Animating the numbers

On worksheet Step 3 we'll start using the table on sheet Step 2. I've left the table in 1, 2, 3 sort for now so we can easily see how it works.

Cell C3 contains a fixed number. We'll start incrementing that number when we start a draw. Cells C4:C28 contain a simple formula: =C3+1. So as soon as we add 1 to cell C3, 1 will be added to all cells below that too.

We'll use these numbers to pick the numbers from the previous worksheet, using the OFFSET function. See Cell G3: =OFFSET('Step 2'!\$A\$1,C3,0,1,1)

Try entering 1, 2, 3, 4 into cell C3 and see what happens. If you're quick enough, the numbers will appear to be moving.

## Controlling the highest possible number in the draw

I needed a way to set a maximum number (the wheel of fortune was used at an event and we didn't know up front how many participants there would be). Worksheet Step 4 demonstrates how this was done.

In cell B1 the max number is set. This cell is used by some formulas AND by a little VBA macro we'll get to later.

Lets have a look at column D. It contains this formula: =MOD(C3,\$B\$1)+1. In effect, this formula causes the numbers to "roll over": to restart at 1, as soon as a cell in col C reaches the maximum value. And I've modified the formula in column F to now use column D for the index, rather than column C. Try entering a number into cell C3 which is close to the current max in cell B1 and you'll see what I mean:

## Making it look like a wheel

So now that we've got the numbers right, lets do some formatting.

Click on sheet "Wheel 1". You'll see I've removed all helper columns, leaving just our list of numbers for the wheel and the pointer to the winning cell:

On Sheet Wheel 2 I have added some colors and borders. This is starting to look nice!

Lets turn to Sheet Wheel 3. I've added quite some trickery there!

• Conditional formatting (look at column AA for the formulas) ensures the number cells have alternate colors
• Two extra columns (to the left and right of the wheel) have been added. Their shading of every fifth row will trick our eyes into believing the wheel turns!
• I've also fiddled around with the font sizes, making the cells near the top and bottom of the wheel appear further away. Just like in a real wheel.

Sheet Wheel 4 shows the one-but-last stage, where I have modified row heights and column widths. Pretty?

Lets turn to sheet Play.

Notice the flashy letters? Conditional formatting again!

Alas, the wheel doesn't turn without some VBA code.

## VBA code

I'm going to be a bit lazy and just dump the code here. There are two  modules.

### Module modPlay

The trickery here is that this routine called "SpinIt" auto-adjusts itself so that it'll take precisely 18 seconds to finish turning the wheel. Why? Because I've added sound effects and the sound effect file (WheelOfFortune.wav) takes 18 seconds to play!

Option Explicit

Dim mlLoopFactor As Long

Sub SpinIt()
Dim lCT As Long
Dim lCt2 As Long
Dim lCount As Long
Dim dTime As Double
Dim dStart As Double
Dim bOK As Boolean
If mlLoopFactor = 0 Then mlLoopFactor = 5000
lCount = Worksheets("Step 4").Range("B1").Value
Application.ScreenUpdating = False
With Worksheets("Step 2")
Do
Application.Calculate
.Range("A1:B300").Sort Key1:=.Range("A1"), _
OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
DataOption1:=xlSortNormal

.Range("A1:B" & lCount + 1).Sort Key1:=.Range("B1"), _
OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
DataOption1:=xlSortNormal
Loop Until bOK
End With
Application.ScreenUpdating = True
PlayBackLoop
dStart = Timer
With Worksheets("Step 4")
For lCT = lCount To 0 Step -1
.Range("C3").Value = lCT
'            DoEvents
dTime = Timer
Do
Loop Until Timer - dTime > (lCount - lCT) / mlLoopFactor
Next
End With
dStart = (Timer - dStart)

'17.5/time*(1/loopcounter)

mlLoopFactor = 1 / (17.5 / dStart * (1 / mlLoopFactor))
PlayBackStop
Application.Wait Now + TimeValue("00:00:01")
Range("Result").Speak
End Sub

Function Add2Numbers(lValue As Long) As Boolean
Dim ocell As Range
Dim oSh As Worksheet
Set oSh = Worksheets("Step 2")
Set ocell = oSh.Range("D2:D1000").Find(lValue, oSh.Range("D2"), xlValues, xlWhole, , xlNext, False, , False)
If ocell Is Nothing Then
oSh.Range("D" & oSh.Rows.Count).End(xlUp).Offset(1).Value = lValue
Else
End If
End Function

Public Sub ResetNumbers(Optional bAsk As Boolean = True)
Dim oSh As Worksheet
Dim bDo As Boolean
Set oSh = Worksheets("Step 2")
bDo = (MsgBox("Are you sure you want to start over?", vbQuestion + vbYesNo) = vbYes)
Else
bDo = True
End If
If bDo Then
oSh.Range(oSh.Range("D2"), oSh.Range("D" & oSh.Rows.Count).End(xlUp).Offset(1)).Clear
End If
End Sub

### Module modSound

To play the sound I used some Windows API stuff. Don't worry if you don't understand this, set it and forget it!

Option Explicit

#If VBA7 Then
Private Declare PtrSafe Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" _
(ByVal lpszSoundName As String, ByVal uFlags As Long) As Long
#Else
Private Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" _
(ByVal lpszSoundName As String, ByVal uFlags As Long) As Long
#End If

'Sound constants
Private Const SND_SYNC = &H0
Private Const SND_ASYNC = &H1
Private Const SND_NODEFAULT = &H2
Private Const SND_LOOP = &H8
Private Const SND_NOSTOP = &H10

Sub PlayBackLoop()
If Len(Dir(ThisWorkbook.Path & "\WheelOfFortune.wav")) > 0 Then
WAVLoop ThisWorkbook.Path & "\WheelOfFortune.wav"
End If
End Sub

Sub PlayBackStop()
Call WAVPlay(vbNullString)
End Sub

Sub WAVLoop(File As String)
Dim SoundName As String
Dim wFlags As Long
Dim x As Long

SoundName = File
wFlags = SND_ASYNC Or SND_LOOP
x = sndPlaySound(SoundName, wFlags)
If x = 0 Then MsgBox "Can't play the audio file. ", vbCritical, "Error"

End Sub

Sub WAVPlay(File As String)
Dim SoundName As String
Dim wFlags As Long
Dim x As Long

SoundName = File
wFlags = SND_ASYNC Or SND_NODEFAULT
x = sndPlaySound(SoundName, wFlags)
If x = 0 Then MsgBox "Can't play the audio file. ", vbCritical, "Error"

End Sub

## The end result

Before I forget, this is the end result. The animated gif isn't as nice as the Excel file however, so make sure you download it (link at top).

That's all folks!

Hi Gian,

I'm afraid the wheel of fortune needs at least as many numbers as I put on the visible part of the wheel (26).

Thanks for your answer Jan, Well, I'll try something on my own but i doubt i can fix the issue ):, any way it is a great file for any one who uses it, Thank you for showing us how to do it as well!

Hi, i am trying to use your wheel of fortune code for my company's lucky draw. I tried to do it using your example however, VBA keep prompting me an error saying "Sub or function not defined. Is it possible if I email you the file and help me to take a look at it?

Hi Lloyd,

Sure, go ahead and send the file. Please refer to this message too.

Firstly, thank you so much for sharing your knowledge.
Whenever I edit, particularly when changing the number of rows, the VBA breaks here...

Thank you for any suggestions you have!

Hi Jeremy,

Precisely which error do you get please?

Comment by: Brandon (10-11-2023 04:22:00) deeplink to this comment

How would you ensure that the already drawn numbers are not selected again upon respin?

Comment by: Jan Karel Pieterse (10-11-2023 11:10:00) deeplink to this comment

Hi Brandon,

In the VBA code there is a function called Add2Numbers which tries to add the current random number to a list of previously selected numbers. It returns True if the new number is not in the list and false if it already is. The calling routine has a Do loop which continues to run until that function returns True.
