The eyeballing game  OCT 16 2008

The eyeballing game tests how good you are at lining things up. I got a 4.46 on my first try, but my hand slipped on one of them so I'm going to try again... Leave your best (or worst) score in the comments. (via core77)

Update: 4.34. I suck at parallelograms and triangle centers.

3.3 average... got a couple 0s but then a 14.7 miss that raised the average. Ouch!

Ivy36 16 200810:36AM

16.97. I have a type of dyslexia that makes this impossible for me to do. I have no visual/depth perception skills at all. I would read a book in the corner and refuse to to Tanograms in Kindergarten.

Sean39 16 200810:39AM

i suck at parallelograms and convergence

Jim Biancolo40 16 200810:40AM

2.10. Convergence gives me the most trouble.

dennis g41 16 200810:41AM

2.33. I wonder if there is any correlation to the supposed right and left hand side of the brain thinkers.

Chris43 16 200810:43AM

2.37. I blew the final Convergence test.

Just out of curiosity: What were your childhood/grade school interests? I'm interested to see if there's a correlation between the scores on this test and an interest in engineering or technical drawing...

Sean45 16 200810:45AM

left-handed (although using right-hand with mouse)
math and science interests, though not engineering or tech-drawing

Grant45 16 200810:45AM

I was doing good on my first one, until some sort of bug on Convergence gave me a score of "15385924.19 (lower is better)".

My second try was a more reasonable 1.90.

Nichole48 16 200810:48AM

I did pretty well on convergences and right angles.

Steve Ivy49 16 200810:49AM

2.86 - I rock bisecting angles, parallelograms rock me.

Michelle52 16 200810:52AM

5.27, including a hand slip that stuck me with a 38.2 on a triangle center. Manually calculating that out gives 3.62. I had one more big outlier, a 14, that I can't explain away with a hand slip, but if I calculate it out too, that's a 2.55.

So I played again, thinking to really put some effort in this time and get the score I "should've" gotten the first time.

I got a 5.52.

Erik54 16 200810:54AM

3.70 is my best after 3 tries.

Dang center of triangles - I hate that one.

billtron54 16 200810:54AM


Mike Rundle57 16 200810:57AM

Erik, yup, the center of the triangle one is what messed me up as well.

Molly57 16 200810:57AM

5.62. My first parallelogram screwed me because I didn't quite get what was going on and missed the mark by 32. Otherwise, fairly good.

jkottke59 16 200810:59AM

I'm having trouble with the mouse pointer getting in the way...I wish it disappeared while dragging.

I'm also a lefty who mouses righty. I've never been that keen on drawing or engineering. Design was always a struggle for me, lots of trial and error and never effortless. Probably explains why I'm smack in the middle of the eyeballing distribution.

Ethan01 16 200811:01AM

Convergence=easiest. Centers = hardest, including bisecting the angle.

I was going to be an engineer or architect but changed my mind. Lots of math and lots of doodling.

Catherine02 16 200811:02AM

I think I'd score way lower if I moused lefty (as a lefty), but as it is, I'm a 4.77 and totally crap with the convergence and triangle centres.

Ben04 16 200811:04AM

What threw me off at first on the triangle one was mistakenly interpreting it as "equidistant from vertices" rather than "equidistant from edges". Makes a huge difference.

Tom Dolan04 16 200811:04AM

2.21 -- first try, should be able to get it a lot better.

ben05 16 200811:05AM

What threw me off at first on the triangle one was mistakenly interpreting it as "equidistant from vertices" rather than "equidistant from edges". Makes a huge difference.

Ryan Sholin07 16 200811:07AM


I bent the convergence line on the first attempt, which netted me a 20 to throw everything off.

Jason12 16 200811:12AM

2.75; parallelograms ARE the hardest part.

Amy13 16 200811:13AM

3.79. Apparently I am no good at bisecting angles.

Armin15 16 200811:15AM

Hit all three center-circles at 0.0! But the parallelograms and triangle centers screwed me up.

Tom Dolan19 16 200811:19AM

Actually, I'm getting worse! Three scores under 3 but getting under 2 is really tough.

karl1120 16 200811:20AM


marc Cardwell22 16 200811:22AM

3.61, this was fun. on one parallelogram, i got a 0, on another a 12.
i'm sending this to the art people at my office/

Megan26 16 200811:26AM

2.62 is my lowest of 4 games. I'm trying to get my husband to play, he's a landscape architect, and after all his time using AutoCAD I think he would be good at it.

Khrys26 16 200811:26AM

2.24. Triangle center was tough.

Sara27 16 200811:27AM

2.21, on the parallelogram. Bisecting the angles was evil, I got a 111.1! :(

Bob31 16 200811:31AM

3.85 best. I can bisect the crap out of angles. But I can't make right angles... this should probably scuttle my woodworking plans.

David Wertheimer32 16 200811:32AM

3.6 on my first time all the way through. The range is more interesting to me than the average... I had a 0.2 but also an 8.5.

Tip: try yanking the positioner away from its starting position, toward the black lines, then slowly repositioning it into the ideal. I find it's far less distracting to start from nothing.

jkottke33 16 200811:33AM

I'm thinking of turning the comments off because YOU'RE ALL SO MUCH BETTER THAN ME! BASTARDS!

Uros Milicev34 16 200811:34AM

hardest part is equidistant point in triangle....really nice test....

Neill Harmer36 16 200811:36AM

3.61. Would have been way lower had I not TOTALLY screwed up on the intersecting points. oh well. this was the best ive gotten so far.

Matt V38 16 200811:38AM

2.86 - I have a long history of being able to notice off-by-1-pixel errors.

harryh39 16 200811:39AM

3.83 with a big boost when I got 0.0 on the right angle

Jenni40 16 200811:40AM

8.66, I forgot what a parallelogram was at first..oops

Chris41 16 200811:41AM

8.07 - and I thought I had done great.

Bill Keaggy41 16 200811:41AM

3.73. Mostly b/c I screwed up the bisect angles.

owen43 16 200811:43AM

6.81. had a few 11s but I'm pretty good at angles. next time have moving targets!

Andrew Helms49 16 200811:49AM

4.61, I also suck at parallelograms (10.8) and triangle centers (16.6).

jkottke52 16 200811:52AM

3.90. F%$*#ing parallelograms.

Dan58 16 200811:58AM

First Try: 3.08 - Midpoints were the worst for me (5.4-7.2), but bisect angles were the best (0.5-1.2). I also got a perfect 0.0 on my last right angle!

I'm a designer by trade. Hopefully that has helped me....

Josh58 16 200811:58AM

11.07 - I'm not sure I even understand the idea of convergence now.

mare02 16 200812:02PM


Furniture maker and programmer

sunkid09 16 200812:09PM

2.36 in my second attempt... blew the last and third to last ones

Mathew Ingram15 16 200812:15PM


Jennifer17 16 200812:17PM

2.41 on my first try! i did a great job at right angles (0.7, 0.3, 0.4). that was fun! i'm an engineer and have always enjoyed math and science, but i'm not sure that has a lot of bearing on how well you do. i actually think for some of the tasks (like convergent and angles), it has to do with how observant you are about the way some pixels look at certain line angles, etc...

metkere.com19 16 200812:19PM

4.03. I think that's not my cup of tea.

Brandon40 16 200812:40PM

3.96, convergence and the equidistant point were my tough ones

metkere.com47 16 200812:47PM

Wow, 2.52 is my best try!

gunnarhafdal50 16 200812:50PM

Got 3.0, the third part screwed me up so it was higher :/

endash57 16 200812:57PM

2.91 ... midpoints on the line were my worst, followed probably by the triangle ones. I rocked at convergence and bisecting the angle

Alaninabox58 16 200812:58PM

Overall score: 3.13

Parallelogram 13.0 2.2 1.0
Midpoint 1.0 4.5 2.8
Bisect angle 7.7 0.1 1.8
Triangle center 3.8 3.7 3.7
Circle center 2.2 2.2 2.2
Right angle 2.7 2.9 0.1
Convergence 0.0 6.0 2.2

I'm not sure what happened with that first one....

Max58 16 200812:58PM

2.17 - Circle center was my worst

sellke58 16 200812:58PM

First (haphazard) try = 2.70. I think I now know why most designers HATE working with me. Be interesting to put a timer on the test, too.

Alaninabox00 16 2008 1:00PM

Architect BTW.

Alaninabox09 16 2008 1:09PM

wow what a great way to blow time at work and impress the boss at the same time...
3.01 on try # 2. I had 3 perfect 0.0's on the midpoints.

Matt13 16 2008 1:13PM

3.96 on second try. Parallelograms are a killer. I find the faster I go, the better my score is.

Norman25 16 2008 1:25PM


not as good as my OCD wants it to be, but not bad!

M27 16 2008 1:27PM

3.18 Another lefty mousing w/ right. Musician.

Gloria32 16 2008 1:32PM

2.82 2nd try. Not bad for an old lady - 61 years old! I'll keep trying until I get in the top 10!

Bill B37 16 2008 1:37PM

2.24 (1st try)
Lefty mousing w/ right. Engineer.

Nick45 16 2008 1:45PM

2.65 Designer. Like the previous poster, I wonder if that helps, or just depends on personality. I think I would suck at the color one or a music test.

Barry Kelly50 16 2008 1:50PM

2.88 first go. Averages were trending down quite a bit, but don't have the patience to do it again.

Billy53 16 2008 1:53PM


I have a strabismus (lazy eye) so my perception is generally skewed.

heather53 16 2008 1:53PM

I did almost perfect on convergence and right angles, which I find interesting given my profession--RN in an ICU. I use a level at work to get many measurements (need to level right atrium of heart to pressure transducer) but must be able to eyeball level often in emergencies, and I need to have a good eye for angles in order to change the head of the bed angle (when I can't see the bed angle indicator). Just thought you'd all like another persepctive than that of designer or architect...

msilver56 16 2008 1:56PM

2.61 I noticed that I was getting really good in the beginning and then I must have gotten sloppy because it dropped sharply after one or two f-ups.

judson 05 16 2008 2:05PM

I can hang a picture real straight! 5.73

Andres35 16 2008 2:35PM

2.73 I totally blew one of the midpoints. fun stuff.

SteveT59 16 2008 2:59PM

Not too bad for a first try
arallelogram 8.1 3.2 6.4
Midpoint 1.0 1.0 2.2
Bisect angle 1.0 4.1 0.8
Triangle center 4.3 1.4 5.8

jenny23 16 2008 3:23PM

2.61 first try.

I can converge like nobody's business. Personally, I think my training as a professional potter gave me an unfair advantage. Always having to eyeball angles.

ess27 16 2008 3:27PM

12.something with a trackpad mouse that I am not supposed to use (disc problems)
Still, it was the parallelograms that got me. No idea even after the green line came on.

Might try again later with this computer up front and a real mouse. Although it would not be possible to do better on center of circles and right angles so I think the paralleograms just got me whipped

atanas entchev45 16 2008 3:45PM

2.26 on the third try.

Virginia Murdoch53 16 2008 3:53PM

3.1. I'm particularly *good* at parallelograms - I got two zeroes. Yay me!

Jen20 16 2008 4:20PM

The lowest I got was 0.0 by bisecting a line and the worst was 10.1 for parallelogram. Mostly I'm in the 2--5 range.

Derek25 16 2008 4:25PM to try it after some wine.

Craig01 16 2008 5:01PM

3.05 busting the last convergence on my second try. More serious.
3.76 on a relatively quick first run where I finished with a 14 on the last convergence test.

Steve Pilon04 16 2008 5:04PM

3.43 -- had one crazy 9.2 or something, otherwise pretty consistently below 4.

Rich23 16 2008 5:23PM

2.40 pretty consistently.

Triangle is my worst by far.

I'm a graphic designer for a newspaper.

Lawrence Velázquez46 16 2008 6:46PM

Scored a couple of ~7s on my very first parallelogram and midpoint tests, which brough me up to a 3.40 overall. Best of 2.00 so far.

Andy39 16 2008 7:39PM

3.50 (breakdown here.)

Josh36 16 2008 8:36PM

2.08 Yeah!!!!

Bisecting, convergence and right angles are simple enough. Centering the circle is actually easy enough, but man I had to look up equidstant centering before i got it right. Geometry class was a really long time ago. This is the only math my art brain is built for.

Michael Bester17 16 2008 9:17PM


Parallelograms and circle centers were elusive for me, but convergence and triangle centers made up for it.

Neil Janowitz32 16 200810:32PM

4.20 on the first attempt. Became one with convergence and right angles, but finding the center of triangles and I really didn't hit it off too well.

Ian Timothy46 16 200811:46PM

4.52 ...
improved with subsequent sets.

Bobby Dragulescu59 17 200812:59AM

2.36, largely thanks to my 0.0 in bisecting a line. Years and years of freestyle (guideless) Photoshop experience have finally paid off!

Jono01 17 2008 1:01AM

2.14 so far (4th try); 3.06 first attempt. This is addictive.

I'm an architecture student and was a math major in college, so I've always enjoyed working with geometric relationships like this, I guess. I sucked pretty bad at the parallelograms for a while but improved after I stopped overthinking them. The triangle centers are surprisingly intuitive, and convergence is sweet because of the extra level of checkability.

lane52 17 2008 1:52AM

it's almost 2am. must stop. eyes going bleary. 3.40. parallelograms are the work of the devil.

kim28 17 2008 2:28AM

Parallelogram 11.7 4.1 1.4
Midpoint 6.1 9.0 1.0
Bisect angle 4.1 4.4 7.1
Triangle center 3.3 6.1 6.6
Circle center 4.2 4.1 4.2
Right angle 0.6 0.8 1.8
Convergence 5.1 11.0 4.2

got the right angle down but somehow not when it's in a parallelogram...oh, is that because there ISN'T a right angle in a parallelogram? okay with the almost consistent offness of my circle centers. as always, thank you, thank you, thank you for you,, etc.

Vincent20 17 2008 4:20AM


I'm either blind or shouldn't be using a trackpad.

Alistair34 17 2008 7:34AM

3.38, largely due to a 15.8 on one bisection. Consistently bad at finding the midpoint, which I thought would be easiest.

Hector Garza43 17 2008 9:43AM

3.79 I had a 10.13 at the 2nd Parallelogram that screwed up everything.

Erica47 17 2008 9:47AM

2.93 - not so bad, but I spent time as a picture framer, so had a lot of practice at right angles!

Ethan52 17 200810:52AM

1.97, which for about 30 seconds was #1 on the top 500 games.

I got this after about five attempts. My finger actually slipped off the mouse on the final right angle so i got a +4.2 but I saved with a 0.0 on the final convergence. I find the triangle centering and midpoint to be the easiest and the right angle and parallelogram to be hardest.

Dorian47 17 200812:47PM

4.98. Parallelograms and triangle centers kicked my butt.

littlejo01 17 2008 3:01PM

4.26 1st time
3.52 2nd time

Convergence is easy. The rest is hard, though it helps to swivel your head.

duq17 17 2008 3:17PM


lines through a mosaic of pixels that have the same stepping are either parallel or perpendicular. paying attention to this gives a big advantage -- been doing this in photoshop for some time.

crosshair cursor would be for yes.

i'd like to see:

- tests distilled and grouped into fundamental skill types (congruency, symmetry, etc) and the effects of focusing on positive vs negative space (ie: for me, bisecting segments is easy, angles are hard).

- tests covering more fundamental types, if there are any (really, i think everything reduces to congruency or symmetry).

- tested strengths/weaknesses cross-analyzed with testee's personality/thinking types and artistic tendencies.

Eric Marcoullier11 17 2008 8:11PM

4.14 -- I can't bisect angles very well.

peter huesken37 18 200810:37AM

2,54 but an 8.1 and a 10 in the last row.

That top 10 is within reach !

peter huesken52 18 200810:52AM

It would be fun to have a version that has a time-bonus as well
Quicker positioning results in a lower score; max positioning time 10 sec.
A bit along the lines of the Traveler IQ challenge:

I Have suggested this to Matthias (Mr. Eyeballing :-)

adam22 18 2008 8:22PM

Nick Olejniczak02 19 200812:02AM

Whoohoo, 2.83. Not. A. Designer.

Andrea35 19 2008 3:35AM

4.34 - it's great to be average

Jeremiah00 19 2008 9:00PM

3.97 parallelograms killed me

Finn55 20 2008 6:55AM

Parallelogram 0.0 1.0 1.0
Midpoint 0.0 0.0 1.0
Bisect angle 0.8 0.0 1.2
Triangle center 1.3 1.3 1.8
Circle center 1.0 1.4 0.0
Right angle 1.1 0.0 0.5
Convergence 1.4 1.4 0.0

Average error: 0.77

4th attempt =) just a wierdo with no life and like to win...

stringph04 21 200810:04AM

2.05 ... after some practice. I found triangle center and parallelogram pretty hard, angles easy.

Obviously there is some random unfairness in scoring the errors in distance as the figures are sometimes larger or smaller, which leads to an intrinsically larger or smaller pixel error for the same level of skill.

The site doesn't seem to remember my good scores...
