I think my score is about even with Stevie Wonder's.

I did much better than I expected. But I would have done even better had I know what "equidistant to the edges" meant. Although now that I just typed "equidistant" I figured out what that means. Duh!

Man, I'm good with that whole convergence and parallelogram thing. The midpoint of triangles, not so much.

3.01... but I should probably do it again since one slip gave me a 19.2 score. :)
posted by rokusan at 10:23 AM on October 14, 2008


The convergence threw me. Don't the lines converge wherever you drag the square? (14 units off, I guess not)
posted by stupidsexyFlanders at 10:23 AM on October 14, 2008


I wonder if it's the triangle midpoint thing fucks most people up, yeah. I'd love to see a per-category breakdown of aggregate scores, but I'm not finding anything like that on the site.
posted by cortex at 10:24 AM on October 14, 2008


2.56! I managed 0.3 in bisecting tho, otherwise would have been much higher.

stupidSexyFlanders, I think it wanted the convergence point of the fixed lines. The ones that moved with the square were just for helpful guidance, as far as I could tell.

Overall score: 3.62. In the most popular point on the graph, apparently.
posted by Pronoiac at 10:33 AM on October 14, 2008


I can do the right angle, midpoint, convergence and bisect really well (~1.0 units if I'm paying attention) most of the time. The others I'm lucky to get inside 4 units if that makes any sense at all.

Fantastic. Great find.

I did bad on this, partly because I have no idea what a parallelogram is. I should probably look that up before I play it again.
posted by nooneyouknow at 10:38 AM on October 14, 2008


The triangle thing gets better with a bit of practice

I was averaging less that 2 when I accidentally clicked near the edge of circle and it took me up to 8! agggh!

3.49 for me, just barely better than average according to their curve - this was fun.

would love to see breakdowns as well...did worst on the parallelogram, equidistant triangle...best on rt. angle, bisecting, center of circle (thinking about the center of circle...i just read last night that the sun is oblate by only 6 miles (!)...even the earth is chubbier around the middle...)

On my cp at least the right angle is off. Each time they add about 2 or 3 degrees. I thought I was imagining things until I checked it with an index card.

If you're running a widescreen LCD, it's easy to end up in a slightly off-square resolution (e.g. 1280x768 vs. 1280x720 modes on 16:9 and 16:10 ratio widescreens, respectively), which would give you that sort of problem.

Likewise, calibration of the picture on a CRT could contribute to off-square (and otherwise sublty distorted) display geometry.

3.04. I do extremely well in the right-angle, bisection, parallelogram and convergence tests, but finding centers is apparently impossible for me. I had three 0.0s.

If it helps on the triangle, picture a circle touching all three sides, & aim for its center.

5.23 My biggest problem was definitely with convergence. 39.2 on the first one... yikes. I got 0.0 on the third circle center, though, and felt ridiculously proud of myself. Cool find.

15.71. In my defense, I really have no clue what you're supposed to be trying to do in the "Find the mid-point of the line segment" and "Find the point of convergence" ones, so I just sort of moved stuff about until the lines looked nice.

That was fun, but I wish the mouse arrow would vanish or turn into a crosshairs. My arrow was very distracting and frustrating.

Convergence is the easiest one... just get all the lines straight.
posted by autodidact at 11:55 AM on October 14, 2008


I was pretty sweet on convergence and the centre of the circle. Crap at the rest though.

I should never attempt to put shelves up either, as I am apparently terrible at finding right-angles.

2.86, but I'm on a widescreen. Centers, bisecting, and convergence were easy - right angles and parallelograms were hard.

3.2. I like it, it's a simple idea and I found the distribution of scores really interesting; I think this must be a fruitful field of research in cognition. Estimating is such a characteristic mode of thought for us; yet you rarely (or I rarely) hear about people modeling it in an attempt to understand, for example, creativity or problem-solving. I also bet it's pretty hard to shift your score significantly even with practice - again, just a guess, but it seems like you're likely to hit a plateau pretty fast. Maybe this kind of thing isn't totally hard-wired but it feels pretty well baked in to me.

2.90. Finding centers is apparently hard, and so are right angles, although I lucked out on the third attempt and got a 0.1 score.
posted by daniel_charms at 12:53 PM on October 14, 2008


Woo, 2.25 for me, good for the #9 slot on the last 500 rounds. The fact that this game is played on a computer monitor means you can cheat on some of these tests a little bit by looking at the stairstepping patterns of pixels on the screen.

The triangle equidistance bit me too... I was going for equidistant to vertices rather than edges which skewed my first two numbers greatly.

3.94. I am the king of Bisection town (0.2), but I've been kicked out of Convergence for drunk and disorderly (12.5).

I kind of want to try it again, but I don't want to know that I'm worse than beginner's luck (averaged over three tries).

posted by simplesharps at 3:38 PM on October 14, 2008


convergence is easy, you just want to make all 3 lines straight. If you can do two of the lines you automatically get the third. So make one line straight, move the cursor up or down that line until one of the others line up.
posted by substrate at 3:52 PM on October 14, 2008


so i pulled a 17.56... and what i'm curious about is The Method.
The Method being how do all you super low scoring folks go about placing your decisions.

are you using visualization techniques?
running off of intuitions ("it just feels right here...").
using tricks that the lay-type wouldn't be familiar with?

my curiosity is piqued as i scored a low ball and was more than a little surprised.
of course, i did spend my whole morning giggling at stupid zen anti-koans... maybe i broke something.
posted by artof.mulata at 3:56 PM on October 14, 2008


I got 0.0 at convergence and I'm now waiting for Sony to call me.
posted by ersatz at 4:19 PM on October 14, 2008


Best of four: 2.69.
I've been trying to identify a consistent technique, artof.mulata, and I can't. For the right angle and angle bisection, I don't really have to think about it--the answer is just obvious. For the parallelogram I make the smaller angles match. Everything else is much harder, and involves squinting and cocking my head and cursing. The triangle center never looks right, even when I'm pretty close. The line segment midpoint always looks right and never is.
posted by hippugeek at 4:52 PM on October 14, 2008


3rd try 3.23...hey, i'm getting better...

as far as technique...looking closelier at how the lines raster/anti-alias on the monitor seems to help...these are all geometric 'constructions', btw...they can all be solved with just a straightedge and compass (no ruler, no protractor) (i think so anyway...its been yuheeears...but i remember enjoying the bit about finding the centers of things using only a compass)
posted by sexyrobot at 5:34 PM on October 14, 2008


What a great post!!

I admit I've played it 3 times now, averaging around 3. I can do bisecting, the parallelogram, the right angle, and the converging lines just fine. I am *really* bad at finding the center of a circle, which is strange, because intuitively I probably would have guessed that circle-center-finding would be the easiest task. It seems as though people here are remarkably varied in their strengths and weaknesses. Very interesting. At first, it seemed as though there was the "I can find the center, but I suck at bisection" crowd and the "bisection is easy but finding the center is impossible" crowd. But now it appears that there's a much wider distribution of eyeballing talents.
