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.
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.

idk, it only took me one click to figure out what the goal was and how I was being judged (beat the average). I feel like that's part of the puzzle. Sort of similar to Baba is You. Figuring out the goal is part of the puzzle.

Oh wow - that is very cool. Thanks for sharing.

Just want to say thank you for sharing your project. Very fun, and I wouldn't know about Matthias Wandel's version if not for yours!
Also, both of these tickled my brain in a great way. I think a potentially fun continuation would be to "eyeball" physics. For example, throw a ball and pause the physics before it hits something (ground, object, who knows?) and guess the location. Or show two objects about to collide with certain shapes and masses and guess what one of them will hit first and where.

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.

Love it!
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)

Cool idea - thanks! I'm building a mobile app as we speak so I'll add it for sure.

I thought this was a random guessing game and kept randomly clicking and felt very frustrated. Once I realized how it works with the two numbers, estimating felt a lot more rewarding.

Got a perfect result for the first try. (Off by zero.) Not trying again. :)
senectus1 1 days ago [-]
yeah i got an off by 1 and decided that was good enough :-D
Almost: 0.07%, allegedly 'perfect'. Getting an early win makes the game so much more 'playable'.

Why does an early win matter? Isn't it random?

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.
hazelnut 2 days ago [-]
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.
harrisi 1 days ago [-]
It is odd. There's significantly more new users commenting here than every other submission on the front page, both in absolute numbers and proportionally.
¯\_(ツ)_/¯

It's a bit of a cheat, but you can hit 0.00% every time. Just measure the bar length, then cross-multiply. :)
Example: bar is 1250px, max is 2100, number is 376 → (1250 × 376) / 2100 ≈ 223.8px from the start, that's the 0.00%.

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.
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.
mrroryflint 2 days ago [-]
Very cool idea! Will try and add.

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.
pedromlsreis 2 days ago [-]
0.11% by luck, because I actually got lucky the target number was too close to zero, out of a big scale.
I am amazed how such a simple app gets that much attention , whereas probably it is vibe coded in an hour using Claude or any other AI tool .
mrroryflint 21 hours ago [-]
I think first prompt to deploy was < 25 minutes - purely to amuse myself.
I have so many other projects that have taken days and in my eyes are way "better" but get zero attention.

This seems like a nice therapeutic application. Something a person or practitioner could say, “Sit down and play this for 5 minutes to calm your mind.”

Presumably I'd do just as well visually near 90 and 95 as near 10 and 5, the difference is in the first stage, estimating the percentage.
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)
*my old pal Claude
Off by 6 on my iPad by mis-clicking. Very satisfying!
A time limit would make sense imho. For extra challenge, add diagonal or curved lines.

handleClick({clientX: els.bar.getBoundingClientRect().left + els.bar.getBoundingClientRect().width / state.n * state.target })
