I can imagine you had enough of all them Ebbinghaus illusions by now, but I promise this the last time! Just wanted to see if all my submissions regarding this topic had any weight, and if the experience you gained helps your brain in processing these kind of tests better. So, which of the surrounding circles labeled 1-8 is the same size as the circle in the middle of the image? Solution will be posted shortly…

either 3 or 4 (I have bad eyesight) so I’ll go for (flips a coin) no. 3

2. ‘Solution will be posted shortly…’

To quote the Moody Blues…”Can I ever get an answer….”

I still think they are all the same…

3. tevor says:

4. TGG says:

6

5. Sarah-Jane says:

I think it’s either 3 or 4….
probably 3!!!
:)

6. ZL123 says:

At first I thought it was all of them but it in fact is 3 :)

7. GAURAV says:

the circles appear to be reducing in dia from 1 to 8.
can’t decide between 3 or 4 , could be the illusion or that the differences between them are too small .
will wait for respone rather than measure

8. pricess says:

but they really look very confusing at first…

9. melpoe says:

it is one, i measured

• A Smartass Girl says:

Your measuring isn’t very good. :P

10. melpoe says:

it is one, i measured it.

its no. 3. i measered it with a ruler

12. agirl says:

really? its clearly 6

• Matthew Brown says:

If you think 6, divide it in 2.
:)

I think they all are the same. I just think the lil circles around the circles are moving away from the circle.

14. Same as ZL123! At first glance they all look pretty equal; however, once any of them either get larger or smaller then #3 is the only precise one! Good one!!

Also Congrats on getting to Yahoo’s! homepage!

15. Ashkenazi says:

16. nice pics on the illusions.

17. April says:

To see the answer click on the pic. BTW its #3

19. Iris says:

I honestly don’t see how it can be 3. Even in the solution, 3 is bigger.

• A Smartass Girl says:

That’s why it’s an illusion.

20. Emily says:

They arent the same size, i measured XP (im not that sad dont worry)

21. Oly says:

They’re all the same size. The trick is that the smaller dots surrounding them gradually move farther away from the dots to make them appear smaller than the center dot. Look again.

22. alice says:

you know, if you have been on this website long, you’d soon realise it’s an illusion- meaning it can’t be six because it looks like it- it’s one or two.

23. ALFONSO says:

THEY ARE ALL THE SAME SIZE, IT’S ALL IN THE DISTANCE OF THE SMALLER BALLS THAT THROW YOU OFF.

24. Julie says:

#4

25. Jon says:

Tis 3 after many minutes of staring. Almost picked 4.

26. Jon says:

Tis 3 after many minutes of staring. Almost picked 4. And they arent the same size.
