Ever since we have purchased the Monopoly board game, it has become a weekend ritual for us. Almost every Friday/Saturday night Jo would pull out the board, currency, wooden dice, small houses and deed cards and spread them.
We are in for a surprise after playing the game for few weeks. As kids we thought the game is a GAME, ie random to high extent but fun. But as we develop an eye for the detail, the game does come out to be rather unfair. How else can you explain that one of us is paying rents through their noses to the other one owning reds and oranges and how else can you explain that the one who purchased properties next to GO seldom gets a visitor, including themselves. We started questioning, is monopoly fair? And thats where I set out to find it myself.
For starters, The monopoly board has 40 cells, and every player starts at GO. The moves are decided by sum of the faces on a 2 dice throw. If you get a double you get to throw again.
I have tried to simulate the game using excel. I have observed all the rules like community chest / chance cards, Jail and go to jail. But I have not observed doubles rule for I thought it had little impact on the outcome. I wanted to see if the expected probabilities of each cell (which is 1/40 or 2.5%) are close to the actual probabilities.
When I ran the simulation for 10000 dice throws for 4 players, the absolute difference between expected probabilities of each cell, color group are more or less near to the actual probabilities as you can see in the below charts. (click on them for bigger versions)
The maximum deviation is to the tune of 6% for individual cells and 1.93% for a color group (for there will be cancellations in color groups, as one cell gets more visitors the other would get less)
But that is not we experience when we play the game. We end up landing in Jail or a chance an awful lot of times more than we expect to land there. Thats because, no one ever plays a 10000 throw per person game, not in day to day versions. Its more like 200-400 throws. So when I ran the same experiment for 200 turns for 4 players, the results were more interesting as you can see them below.
As you can see the deviation in the actual probability and expected probability is huge. Some times 60% more for individual cells and 20% for color groups. This I guess explains the reason behind the Monopoly game strategies like buy anything in Orange and Red groups etc.
Obviously one fault of this experiment is if you run it again the actual probabilities are going to change in favor of something else. But almost always far from the expected results.
Write to me just in case you want to play around with my monopoly board game simulation excel sheet, I can mail it. The file is rather huge for upload.

This borders on Excel soft-cell...er, soft-core...porn. My favorite kind.
Wow, that is pimp-TASTIC! I have a question, as a VBA n00b: additional comment boxes stay plain unless I "run" the macro. Is there a way to change all comments, going-forward?
hi Chandoo, well, I like the macro approach. For those who don't like it, there is another way: just add the "draw" toolbar to the shapes toolbar (via Custom etc), click on "edit comment", click on the auto-shape and then choose "draw" drop-down, --> modify auto-shape --> then you even can have a heart or a banner (I like the horizontal banner in in purple :-)) . in excel 2007, you have to add this custom menu that you choose via Excel Options --> Custom --> it is called "change/ modify auto-shape"!!!
best,
@Chandoo. Great Post 🙂
@Tim : the way the macro is coded, it must be run very time.
@Community: If someone has an idea to perform it when opening an existing excel, it should be nice.
@Community: if someone has some code to revamp the commentboxes on all sheets, please share it. 🙂
@Microsoft Excel-progammers: some pimpoptions for the commentboxes should be great.
Cheerio
Tom
For the auto run, please add the codes in workbook:
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Call Comments_Tom
End Sub
Wow, that was a lot of fun... Thanks Tom!
@Jeff... Now, 5000 people know about your favorite porn... 😛
@Tim ... you can write an event to handle the new comments. I wouldnt recommend it as it is really painful. another option is to use the macro suggested by Yukikomi. It will update comments everytime you activate the sheet.
@laguerriere: very cool 🙂
@Chandoo ... Thanks! This is good stuff. I combined your tip with a tip from Mark O'Brien, then assigned it to a button on Excel 2010's Quick Access Toolbar, to format comments AS I add them. I also like how Mark's code saves me the trouble of backspacing my name out of new comments:
Sub AppendToExistingComment()
'Source: Mark O'Brien at http://www.mrexcel.com/forum/showthread.php?t=57296
Dim oRange As Range
Dim oComment As Comment
Dim sText As String
'Use object variable to hold range.
Set oRange = ActiveCell
'Use object variable for comment
Set oComment = oRange.Comment
'text to be added to the comment box
sText = InputBox("Type text to be added:", "APPEND TO COMMENT TEXT")
If Len(sText) = 0 Then End
'If Active Cell has a comment then append new text to the end of the comment text
If Not oComment Is Nothing Then
sText = oComment.Text & vbNewLine & sText
oRange.Comment.Delete
End If
'Add a comment with the contents of sText
oRange.AddComment sText
DoEvents
Comments_Tom
End Sub
Thank you very much for the code, it seems to be working for the most part; I am having a problem however. Once the routine makes the corrections to the comment, the comment becomes invisible. By invisible, I mean that when I highlight my mouse over it, nothing appears. However, when I right click the cell and click 'edit comment' then the comment becomes visible and I enter edit mode. Upon clicking out of the comment, it simply vanishes again. I've tried to fix this problem by adding a .shape.visible = msoTrue but then every comment is always visible. o_O please advise...
Thank you,
Nick
@Nick- That is because the font color of the comment is white and when you select the color of selection is also white hence you can not see anything. Try to change the color code in the routine to something else. would work
Thanks for that! The code works perfectly!

@ Chandoo - code works great and the comments look super cool. But I have ran into a small issue. In the comments, I am inserting pictures. When I run the macro, for all comments which already have pictures; pictures are deleted. Pls help me retain the pics in comments.
[…] posted some code one of his readers submitted, it "pimps" your comment boxes from those boring black-text-on-yellow rectangles to something more professional and eye-pleasing. […]
love in it
Hi Tom,
This looks really excellent. I am however relatively new to macros / VBA codes so having copy pasted your code in the Developer mode of an Excel file, what are the next steps to use them? Can you please help? Just to recap, I opened a blank Excel workbook, clicked on Developer, copy pasted the comments code and saved the file to the desktop.
Now how do I go about using it to add comments to an existing file? My apologies for asking a question which may be basic to you great geniuses, but I am not there yet and aspire to get there.
Many thanks for helping me with next steps that I need to take so that I can now use the code.
Best Wishes

Dear Dave,
The best thing to do is to copy the macro in the personal.xls(x) file. The personal excel file will always be launched when you open excel so you can use it with every excelworkbook.
Read all about it on the page of Microsoft.
https://support.office.com/en-us/article/Copy-your-macros-to-a-Personal-Macro-Workbook-aa439b90-f836-4381-97f0-6e4c3f5ee566
Once you have the macro in the personal, you can 'call' the macro by the keyboardcombination 'alt+f8' and klik on the macroname.
Hope this clarifies the 'how to'. Good luck with your first steps in the wonderfull world of macro's.
Tom
Hi Tom,
Many thanks. I will try that out. Learning is fun and learning this stuff is even more amazing.

There is a line 'Dim LArea As Long' which does not appear to be used. Have I missed something?
Dear Gary,
Correct the 'Dim LArea As Long' is indeed not relevant and can be deleted.
Tom
Excellent hack!
For some reason when I opened my file after using LibreOffice Calc, all comment boxes had changed to some arrow shape.
So this macro helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
I used it with the following attributes to get back old style comments:
It helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
.Shape.AutoShapeType = msoShapeRectangle
.Shape.TextFrame.Characters.Font.Name = "Calibri"
.Shape.TextFrame.Characters.Font.Size = 10
.Shape.TextFrame.AutoMargins = True
.Shape.TextFrame.AutoSize = True
Thanks a lot!
This was helpful, thank you
I think this is among the most significant
information for me. And i am glad reading your article.
But wanna remark on some general things, The site style is great,
the articles is really great : D. Good job, cheers
Is there code to add to this that will format a particular part of the comment (i.e. make the last sentence in the comment bold and in italics)?
This is fantastic!
How would I add auto-sizing to it?
I tried adding this:
.Shape.AutoSize = True but it gives me an error and as a novice at VBA I can't figure it out.
.Shape.TextFrame.AutoSize = True
Hello I am so glad I found your web site, I really found you by accident,
while I was browsing on Bing for something else, Nonetheless I am here now and would
just like to say thanks a lot for a remarkable post and a all round entertaining blog (I also love the theme/design), I don’t have time to
read it all at the moment but I have book-marked
it and also added in your RSS feeds, so when I have time I will be back to read a lot more,
Please do keep up the fantastic work.
This is GREAT!
How should the code be changed in order to tun once for all worksheets in a workbook?
