A modern take on Matthias Wandel's classic [0], which has you guess a variety of geometric attributes (e.g. angle bisection, centroid locating, shape regularization), not just simple partitioning of a line.
It would be great to have a 'training' mode, where you get to repeat ones you miss. This would increase the learning speed.
Easy training- repeat the one you just borked
Medium training- cycles through say 5 examples until you get all five within your target range (1%, 0.1%, whatever)
It's interesting that there are, at the time I'm commenting, 11 new users commenting on this submission, some commenting multiple times. I wonder what the effect of "share my score" type pages have on account creation.
yes, was thinking the same. but it's also weird that the amount of new users commenting is so much higher here. wonder if that is just not a coincidence.
The fact that the numbers are in a brighter color than the end marks, and that the numbers go inwards, makes it slightly more difficult than it would otherwise be, because the eye is biased by the more prominent space between the numbers being different from the line between the marks.
Great idea! Have you considered storing triplets <range, correct number, selected number> for each try and making image plots of these (x/y coordinates are correct/selected numbers, color of each pixel represents frequency) for multiple users for each range? I think the image might reveal interesting properties of human eyeballing, like near-perfect accuracy around 50%, but with less obvious correlations.
I didn't think I'd be any good at this. What I didn't expect is how wildly inaccurate I'd be on every single goddamn attempt lmao it's like I completely lack whatever part of your brain is required to do this

Oh that version actually made sense.
Going back to our newer game, I realized that I am supposed to figure out where the number given should fall on the line.
A case study in modern useability - looks a lot cooler, can't figure it out.
This is great. If only the little square tool would disappear while I make adjustments though - it's just enough of a distraction to barely miss.
Oh wow - that is very cool. Thanks for sharing.
Love it!

Cool idea - thanks! I'm building a mobile app as we speak so I'll add it for sure.
I was 0.06% off on eyeball. Beat me: https://eyeball.rory.codes.
This is fun!
> perfect - you picked 0 · off by 1 (0.03%)
0.10%, but on a touch screen.
Almost: 0.07%, allegedly 'perfect'. Getting an early win makes the game so much more 'playable'.
My best on first attempt was 0.00% (Pure coincidence) . But was fun!
https://eyeball.rory.codes/ I was 0.20% off on eyeball. Beat me: https://eyeball.rory.codes
I reached 0.05% and retired for the day.

I love these simple games that take 2 seconds to understand the rules.
Off by 6 on my iPad by mis-clicking. Very satisfying!
Thank you!
Nice! Would be nice to see your progress over time (if you got better, also as a function of speed...)
0.11% by luck, because I actually got lucky the target number was too close to zero, out of a big scale.

Very cool idea! Will try and add.
I love these kind ones! Really engaging also yes as someone commented, the training mode would be an awesome idea.
Also, I tried this on laptop as well as my phone, I liked it more on my phone (I know the whole point is about precision though)
I'm* building an app currently!

The low contrast of this website hurts my eyeball
This is fun but you need to put "click the line" higher on the page. It took me a while to figure out what I was looking at.
Just any kind of contrast between foreground and background would help.
same happened to myself as well.
Cool idea, love how simple it is. Minimal and clean.
Well I suck.
I built it and still suck, don’t feel so bad.

Definitely need an iOS version! An angle version on a circle would be nice too.
Just wrapping up the beta for iOS! Will let you know asap.
What does native give you that this doesn't?
10 round avg 4.5%.
A time limit would make sense imho. For extra challenge, add diagonal or curved lines.
Oh, this is actually fun! How about if you change the target every few seconds to add a bit of pressure.
10 perfect hits in a row!
...
handleClick({clientX: els.bar.getBoundingClientRect().left + els.bar.getBoundingClientRect().width / state.n * state.target })
800
0 out of 1,600
I still missed. Even when there was centered text.
Maybe the human is the weakest link
this is fun and helping me get grounded :). adding a timer would be a good idea, I think.
love it, pulls you in after a first try)
Simple premise, oddly hard to put down.
Really fun! I am pretty much blind
i got a 0.00% after 3 tries!
this was fun
this is fun!
pretty fun!
i made 0.87%
my best is 0.08%
> I was 0.00% off on eyeball. Beat me: https://eyeball.rory.codes
(It was pure luck)
my avg was around 2% not able to do more than that lol
