How many black spots can you count while looking at this image? 1? 16? 100? Don’t know, I never manage to concentrate fully. Another effect you’ll notice that the “spiral” is somehow approaching you. So this makes it double optical illusion! :)

This one is easy.

There are ZERO black spots :)

I knew this one, but instead of various circles, the illusion was various squares, with no depth illusion. The black spots were more “visible”… but this one is very nice too!

The one at the center is actually a black spot. The correct answer is 1.

thats not really a dot now is it????

thers 2 the big circle and in the middle :D

When I stare at the center, the whole thing seems to vibrate and move about.

i dont know bout that but i think there is one and its in the center…trick is dont think “inside the box”, its on the out side.

brett

my eyes can’t focus !!!!! too many too many dot dot dot dot after BLACK DOTS EVERYYWHERE

theyre all about. i can’t focus on counting one by one.

you’re not alone, fuzzy

actually there is 1 dot. its in the center DUH. lol

its not count the black dots!

its count the black SPOTS!!!

and if u look at 1 row and count them 2 the middle there are 15, multiply that by the amount of rows there are around the circle and u get 40. 15 X 40 is 600 plus the black circle in the middle leaves 601.

not that hard people ;P

if you stare at the center without blinking it get’ssmallerNOOOO!!!!!!!!! MAKE IT STOP!!!!!!!!!! AAAAAAAH!!! NO! NO! AAAAAARRRRRRRRRRGGGGGHHHHHHH!!!!!!!!

I found 206 and then I passed out!

WHEN I LOOK TOO THE SPOTS THEY DISAPPEAR

i dont see any black spots (except one in middle) am i weird? i never got this one.

too many dots………can’t c…..@.@

I love he way you explain everthing M 2 the H O! it’s way kool and you always make sense! i envy you! really !yeah umm theres like none except for the one in the middle but technically thats a circle..arn’t dots small

There is only one black dot and it is in the middle. there are 600 white spots.

Well I only counted one black dot/circle but i also counted 600black squares.

wait i get it when you look at it u see black spots where the white opnes are. very clever but grrrrrr mean

this is so old. i’m sick of it sorry but you have this atleast seven or so other times on the site.

M 2 the H O is so right i counted too and there is 600spots and not dots guys how come cant u read

in theory there are 600

HMMM…

A TRICKY ONE BUT IF YOU COUN’T THE WHITE DOTS THAT’S HOW MANY BLACKDOTS THEY AS THEY APPEAR WHERE YOU ARE NOT LOOKING

SECONDLY…. IF YOU READ THE DESCRIPTION IT SAYS THE

SPIRALIS COMING TOWARDS U…IF YOU LOOK CLOSELY IT IS ACTUALLY LOTS OF CIRCLES!You have got it all wrong in how many dots there are.

It is quite simple.

Just the 600 little dots.

The one in the center…

AND THE WHOLE THING!

Hello?! The whole thing is a big, black dot with white thingies in it.

your forgetting about the one at the end of the tunnel.

There is one black spot

Also, the whole thing looks like a tube.

there are 17 rows of 40 you can calculate that yourselves i did the first counting

there are 600 black spots and 1 un the middle,

there is no neccesity to cout one by one

dudes i think there is only 1… the big one with all the squares in it?

its pretty easy.just count the white ones.I dont know if it’ll work cause im to lazy to count them.

you keep looking around and there is sooooo many black dots but they are there for a split second. there is no way anyone in the world can count them!

dude-it gets bigger fur me and wat made u tink dat its getting smaller? ITS GETTING BIGGER!!!!!!!!!!!!!!!!!!!

No black dots, your brain made em up

Excelente la verdad es muy difícil saber cuantos puntos negros hay creo que no hay ni uno solo la vista hace creer que hay…

I don’t get what you mean by black spots, but this is like the Hermann grid illusion, where black dots seem to appear and then vanish in the white spaces.

there are two spots, if u count the whole black circle and then the one in the center

if u can cont the white spots u r really counting the black spots

i could only coubt like 50 then it was all weird. but it’s not a double illusion. if you look closely, the squares towards the center look like circles. but as you move to the edges of the circle, they turn into squares.

Just fix your eye toward the center and you will see no black spots.In your eye retina -as every one-there is what we call “a blind spot”,when your eye moves and it wil move,the images of the white spots will fall on that “blind spot” of your eye retina in random,which means they will tern black and white in random and you will not be able to count them.It is a funny tool.

am i going crazy cuz i dont see any…or is that the illusion

680 black spots are thr….

Well if you count spots in circle you will get 40, when counting columns you will get 15-16 (cant rlly tell becuz of the bad quality; but I believe 16). And finally +1 spot in the center :D

40*16+1= do the math ;)=681

I believe squares and circles go under spots as well, so it cant be 0.

Your equation is correct but your multiplication skills suck: 40 x 16 = 640 , 640 + 1 = 641 = the number of black spots.

641* xD

DERE THERE ARE NO AND I MEAN NO !!!! BLACK DOTS THERE ALL WHITE !!!!!!!!!

ABSALOUTLY NOOO WHITE DOTS

WILL SOME BODY MARRY ME I’M 20 AND REALY PRITTY !!!!

There are 641 black spots (note that a spot can be any shape and doesn’t have to be circular). Each concentric ring contains 40 black spots and there are a total of 16 concentric rings (note that it is arguable that there are 15 concentric rings due to there being no apparent enclosure of the spots on the innermost ring). The last spot is the spot in the middle. So we multiply 40(number of spots per ring) x 16(number of rings) + 1(spot in center) gives 641 total spots (or 601 if 15 is determined to be the number of rings).

simple. THERE ARE NO BLACK DOTS, only white dots. and remember, we’re talking dots, not spots. but why zero (aside from the center)? it’s cause you’re brain somehow interprets these white dots as black when you glance around. maybe it’s because of the contrasting background colors, (black contrasts white) and the background is black while the grid is white. I don’t have a specific explanation for it, but I’m sure it has something to do with your brain interpretation due to contrasting colors. nothing more, nothing less. if you’re in doubt, try making a red and green or a yellow and purple one instead of a black and white. either way, the contrast will always appear if it is arranged in such a way as that spiral. remember, contrasting colors!

Haha, just try loocking at it with one eye. That way you’ll find the proof there are yero black spots. The illusion appears because you are using 2 eyes to see the picture, and the pictures fro 2 eyes merge together. So in place where you see the white circle on one eye, you see the black block on another.

its a simpel calculation.

but there are 600 black squares and 2 black circle.

I you are looking verry square on this one.

There i ONE big dot and a lot of white squares.

3560 black bspots

This is a POLAR ARRAY. The instructions were to count the black SPOTS (not just the black DOTS) Technically, those are not squares; those are ARCs. Further, there is no spiral here, since the circles are CONCENTRIC.

If it’s difficult to count one full layer, just count one quadrant. It’s 10. Multiply by 4 quadrants, then each layer (full circle) contains 40 black ARCs (or spots). Counting the depth, there are 15 layers in all so 40 times 15 equals 600.

Others are confused whether there are 16 or 15 layers/full circles. Count the bright white spots minus 1. Since this is 16, therefore, there are fifteen layers in them.

Plus the big circular black SPOT at the center.

Answer = (15 x 40) + 1 = 601.

if u look at 1 row and count them 2 the middle there are 15, multiply that by the amount of rows there are around the circle and u get 40. 15 X 40 is 600 plus the black circle in the middle leaves 601,then subtract 1 from each row!!! the total is 586 counting middle spot

Pfft, nerd! ^

Actually, there is one physical black spot (in the center).

All the rest are just our eyes trying to recognize the difference between the colors and we’re seeing flickering black spots. Can’t explain it better than that, however there is only one black spot.

“Count the black spots”

-Challange Accepted

well this is pretty simple math if you count all the outer black spots there is 40 then you count the black spots down and there is 15 then you multiply and get 600 then you add the you add the big black dot in the middle and get 601

it makes sense if you cut the circle in half then lay it out like a map it will just be a rectangle then you count and multiply base and hight and add the middle dot and you got it

I counted 702 black squares

680 black squares 600 white dots

697 black squares O.o just count one row from the outer ridge to the center and then multiply that by the number of black spots on the outer ridge itself. it should be 17 from out to in, and 41 all around.

there’s 615 white dots
