This is my walkthrough for the Mighty Hoax level 4-20 for the iPhone game Angry Birds.

You can get all three stars in this level by only using four angry birds.

wpid 4 20 Level 4 20 Walkthrough for Mighty Hoax in Angry Birds

  1. Aim the first angry bird directly at the first pig on the left. It will explode taking out four pigs and the entire left structure.
  2. Aim the second angry bird at a low angle to go right through the wooden blocks in the center. You should get three pigs with this bird and expose the structures on the bottom.
  3. Aim the third angry bird at a low angle and drop its egg right at the edge next to the pig on the left. You will be able to get one pig.
  4. Aim the fourth angry bird at the last two pigs, and you will get them easily.

If this strategy worked for you, or even if it didn’t, please leave a comment below and let me know.

    thanks for this. I didn’t actually achieve the same scenario as you, but it certainly helped me determine I was on the right track. I ended up with a score of 112820 and 3 stars. Cheers

    I can clear all the birds and I have a score of 106800 but still can’t get 3 stars. Any advice?

  3. Kathy says:

    Worked Great… I have been trying to beat this level for almost a week without success and this is the first one I couldn’t beat on my own! Thank you so much!

  4. Pamela says:

    Thanks for the run through. YouTube is sooo slow today & this level has been driving me bonkers!

  5. CassieXOXOXO says:

    I tried to get it at least 10 times before I got on here after I saw it got it in two tries.

  6. Dave says:

    The first bird needs to fired through the wall before you detonate, which was new to me.

    I thought black bomb birds needed to be detonated before impact, so not only did this help me clear the level with one, bird left, but I learned somethung new.


    P.s Android version on HT Desire

  7. Jessi says:

    I agree Kathleen. I tried that first step on my own before looking for help online and I still can’t get that first one to clear 4 birds. Grrrrr. Good to know I am on the right track, but still no success.

  8. Des says:

    It wrked for me, have an android, at first I refused to look at walkthroughs but after fitty thousand failed attempts it was agrivating lol but thnx I love the help!!!!!

  9. Cara says:

    Great tip s very helpful!

  10. kathleen says:

    The first bird seldom clears the 1st 4 pigs. Almost overtime it leave obstacles that prevent the structure from coming down. So either other players have bionic birds or it took them hundreds of tries! Haven’t been successful yet.

  12. Erin says:

  13. livingpr says:

  14. Staci says:

    Thank you so much have been trying to beat this level for two days and did it on the first try your way. Thanks again :)

  15. jj says:

    it worked

  16. Greg says:

    Worked! I got 115,790 after a few attempts.

  17. ieva says:

    I used the first two steps and then did my own thing after that but it worked really well! Thanks for the idea :)

  18. Paula says:

    Worked like a charm!

  19. ruidh says:

    Maybe the android version is different, but I’ve tried this method several dozen times and I just can’t get the first or second birds to clear nearly as much debris. I get 4 pigs with the first bird about one in four times but several of those have obstacles for the second bird. I’ve never gotten that one to clear four pigs.

    I made it this far without even looking at walkthroughs, but this one has me stumped.
