Unlock “Angy Formulas” – an Angry Birds like game hidden in Excel using this trick!!!

excel apps - 143 comments

Sometimes you think you know something and then suddenly you are surprised. Yesterday was such a moment for me. I have been using Excel for almost a decade now. So naturally I assumed that I know it well. But then yesterday, while doing something I stumbled on a strange screen in Excel that looked like very popular Angry birds game. So I got searching. But there was no mention of it anywhere on net. Then I asked my friend Rollf ‘O’ Pai, who is in Micros0ft Execl team. First he denied such a thing. But we knew each other so well that he could never lie to me. So he confided. He told me what I had suspected for several years.

There is an Angry birds like video game hidden in Excel!!! It was meant to be an Easter egg in Excel 2010 (and 2013), but due to backlash from senior management no one ever published the details about it.

So I asked him “How do I unlock it?”. Rollf ‘O’ Pai asked me to never reveal it to anyone and then told me the recipe.

Once I unlocked I could not believe how cool it is!

Angry Formulas - Hidden game in Excel 2010 & Excel 2013

So I have decided to share with you all so that you too can play “Angry Formulas” right inside Excel (2010 or above).

Follow these instructions to unlock Angry Formulas.

  1. Open a new file in Excel 2010 or Excel 2013 (works in Excel 2007 SP2 as well)
  2. NOTE: You must close any files you have open and only have this new file in open state.
  3. Save the file with this name “ARoofPill.xlsx” (apparently ARoofPill was the code name for Angry Formulas when it was being developed!)
  4. Go to Cell C23.
  5. Make it 300 pixel wide. (Note: Make sure it is exactly 300 px.)
  6. Change the font size to 20 pts
  7. Type the below formula (copy paste for best results) as is.
    & CHAR(82)&MID("SMILE",3,2)
    & ADDRESS(2^5,57*3,4)
    & MID("COOL",3,456789),"32","")
  8. Press Enter.
  9. Enjoy Angry Formulas!

NOTE: If you loose any level in the game, you must restart at Step 1 (above). So play responsibly.

PS: My highest score is 3921. I have managed to reach up to level 4-3 before failing. What about you? Post your scores in comments.

    I got several issues while trying to unlock it...
    First, I use excel prof plus 2010 in spanish ( i am from there ) and love your blog but I am way behind the level of the blog...( yet I hope ).now...the issues
    a) How do I complete point 5( 300 pixel wide cell )
    b) The formula... its in english... I tried to do the same in spanish but didn´t make sense:
    & CARACTER(82)&EXTRAE("SMILE";3,2)
    & DIRECCION(2^5;57*3;4)
    & EXTRAE("COOL";3,456789);"32";"")
    Could someone help me?
    Thanks a lot!

    • cALi says:

      • Gonzalo says:

        Thanks CaLi!
        ( just have to change the , for ; afterwards )
        I feel like a:

    • I used following macro:
      Public Sub InsertFormula()
          Dim s As String
          s = "=SUBSTITUTE(ADDRESS(BIN2DEC(1&REPT(""0"",5)),6*7,4) "
          s = s + "& CHAR(82)&MID(""SMILE"",3,2) & ADDRESS(2^5,57*3,4) "
          s = s + "& MID(""COOL"",3,456789),""32"","""")"
          Worksheets(1).Range("C23").Formula = s
      End Sub
      It worked well for russian version of Excel and it seems to work for any other language

       " In the Column width box, type 10 (75 pixels wide), and then click OK. "
    Thanks for making me laugh today.  I hope everybody enjoys the game as much as I did.

  49. V S Venkaraman says:

    Innovative way to Fool..... enjoyed.... 

  50. Whoa, what a fun game 🙂 I've cleared all the levels and unlocked the "April Fool" achievement.
    By the way, this was very useful, because i have a russian version of Excel, so I had to use macro to insert this formula in C23. Here is the text, it will work on any language version of Excel, I think:
    Public Sub InsertFormula()
        Dim s As String
        s = "=SUBSTITUTE(ADDRESS(BIN2DEC(1&REPT(""0"",5)),6*7,4) "
        s = s + "& CHAR(82)&MID(""SMILE"",3,2) & ADDRESS(2^5,57*3,4) "
        s = s + "& MID(""COOL"",3,456789),""32"","""")"
        Worksheets(1).Range("C23").Formula = s
    End Sub

  51. Sameer says:

    Awesome! 🙂

  52. Stef@n says:

    i am looking for the GERMAN formula ;O
    who could help ?

  53. subbiah says:

    hello chandoo,
    a simple design familiarity made me aware of it ,the fonts which you used in the picture, the date,the simplicity in your designs told it all.even then curiously i typed and  got the wishes .
    subbiah (andamansikkim.blogspot.in)

  54. Gobal says:

    Chandoo.. your alway a step ahead !!!!

  55. Carolanne says:

    At least I figured out what pixel wide meant:)

  56. Mark S. says:

    Very cool. Even in jest I learned something about character width and pixels.  Got me hook, line, and sinker!

  57. Leon Kowalski says:

    Ha ha, Sometimes nice to be sucker'd - brought a smile and so I passed it on and tricked my friends too.
    Thanks Chandoo

  58. Sagar Vadge says:

    Nice One.. Ha Ha
    Thanks Chandoo.

  59. Tan says:

    Awesome 🙂

  60. Abhilash VK says:

    April Fool..!

  61. Sri says:

    LOL..... thanks

  62. Narasimhan says:

    When you mentioned to save the newly opened file as "ARoofPill.xlsx", I understood that it is for "April Fool". Although, knowing this I tried with the steps to show it to my colleague.

  63. Susan says:

    Not quite as amused as others. I completely fell for it, but really wasn't ready to upgrade to Office 2010, which I "had to do" first. That's why it took me 2 extra days to try it.  I'm not going back to 2007; now need to get used to all the new look-and-feel on Outlook, Word, Excel, etc.  Forced upgrade, and I'm not feeling gratified with the outcome.

  64. Steve says:

    You got me.
    Nicely played.

  65. Praveen says:

    I was spending a lot of time for doing that 300 pixel and got to learn from this website:
    But I was not fooled, learnt about pixel measurement 🙂

  66. Ranjan says:

    April Fool...

  67. Guillermo says:

    There's no such a game in Excel !

  68. Glenn says:

    Seeing this on 5 April, I got as far as copying the formula before the penny dropped - nice one Chandoo : )

  69. Elena says:

    I was just about to go and try but I paused and was like wait a minute... if he promised not to tell why is he telling us? What day was this posted? And then I was like--I knew it! Good one, Chandoo!

  70. Hui... says:

    I can't believe so many people got caught on this!
    However I just noticed the file name: ARoofPill.xlsx
    Very clever Chandoo

  71. AShish says:

    Ha ha ha.... you made a fool out of me.... but its still amazing... April fool....

  72. Jana says:

    Hmm. Good

  73. Robert says:

    Very good my friend - you had me fooled!

    I tried a several times and eventually came to know that it is giving answer as April Fool...............

  79. Amy Sampels says:

    I love it!  I was really looking forward to some Angry Birds time but I got a good, healing laugh when I saw 'APRILFOOL'. And for those who got ticked because we did something fun that took a little work...WARP DOWN!!!

  80. Mayank says:

    Was there a file to download?? If so, I am not seeing that...

  81. Sam Mathai Chacko says:

    I was more interested to know if there was any message in the last line from Chandoo.

    "My highest score is 3921. I have managed to reach up to level 4-3 before failing. What about you? Post your scores in comments."

    Did the 3921 and 4-3 mean something?!

  82. Abid says:

    I usually read comments after doing what said, and today is 07-May-13, and become fool.
    Great on

  83. Abhimanyu says:

    This was so much fun.

    I have read so many of your tutorials without commenting. This one was just irresistible. Even a month and a week after it was intended to be.

    Keep up the good work.

  84. Jeremy says:

    Hahaha, this is awesome.

  85. Joy says:

    Ohh Chandoo... soon there will be a game you will face, "Angry People!"

  86. Honey Boo Boo says:

    Damn it 🙂

  87. SpreadSheetNinja says:

    Public Sub InsertFormula()
    Dim s As String
    s = “=SUBSTITUTE(ADDRESS(BIN2DEC(1&REPT(“”0?”,5)),6*7,4) ”
    s = s + “& CHAR(82)&MID(“”SMILE”",3,2) & ADDRESS(2^5,57*3,4) ”
    s = s + “& MID(“”COOL”",3,456789),”"32?”,”"”")”

    Worksheets(1).Range(“C23?).Formula = s
    End Sub

  95. abc says:

    You proved yourself 'a wise man'. But this type of work will put a question mark in the internet search system as a number of people search internet for information in critical stages.

    & ENDEREÇO(2^5;57*3;4)
    & EXT.TEXTO("COOL";3;456789);"32";"")
