- p2hari 4mo agoMy best on first attempt was 0.00% (Pure coincidence) . But was fun!
- nextma 4mo agomy best is 0.08%
- zer0tonin 4mo ago> I was 0.00% off on eyeball. Beat me: https://eyeball.rory.codes https://eyeball.rory.codes (It was pure luck)
- trickybusiness 4mo agothis is fun!
- zer0tonin 4mo agoThis 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.
- ketul_shah 4mo agosame happened to myself as well.
- oneeyedpigeon 4mo agoJust any kind of contrast between foreground and background would help.
- elliotJames548 4mo agoi made 0.87%
- ketul_shah 4mo agothis is fun and helping me get grounded :). adding a timer would be a good idea, I think.
- pedromlsreis 4mo ago0.11% by luck, because I actually got lucky the target number was too close to zero, out of a big scale.
- forlorn_mammoth 4mo agoLove 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)
- mrroryflint 4mo agoCool idea - thanks! I'm building a mobile app as we speak so I'll add it for sure.
- ashm1104 4mo agoI 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)
- mrroryflint 4mo agoI'm* building an app currently! *my old pal Claude
- ramon156 4mo ago800 0 out of 1,600 I still missed. Even when there was centered text. Maybe the human is the weakest link
- zokier 4mo ago10 round avg 4.5%. A time limit would make sense imho. For extra challenge, add diagonal or curved lines.
- davidcollantes 4mo agoI was 0.06% off on eyeball. Beat me: https://eyeball.rory.codes https://eyeball.rory.codes. This is fun!
- Theodores 4mo agoAlmost: 0.07%, allegedly 'perfect'. Getting an early win makes the game so much more 'playable'.
- stavros 4mo agoWhy does an early win matter? Isn't it random?
- pelagicAustral 4mo ago> perfect - you picked 0 · off by 1 (0.03%)
- layer8 4mo ago0.10%, but on a touch screen.
- tgamma 4mo agoI was 0.00% off on eyeball. Beat me: https://eyeball.rory.codes https://eyeball.rory.codes Lucky punch, on a touch screen!
- 0x000xca0xfe 4mo ago10 perfect hits in a row! ... handleClick({clientX: els.bar.getBoundingClientRect().left + els.bar.getBoundingClientRect().width / state.n * state.target })
- joey9prints 4mo agoCool idea, love how simple it is. Minimal and clean.
- aspectop 4mo agomy avg was around 2% not able to do more than that lol
- antoine-codefly 4mo agoDefinitely need an iOS version! An angle version on a circle would be nice too.
- mrroryflint 4mo agoJust wrapping up the beta for iOS! Will let you know asap.
- tantalor 4mo agoWhat does native give you that this doesn't?
- perilunar 4mo agoSeveral megabytes downloaded instead of (checks dev tools) 5.1 KB.
- throwawaydudhdn 4mo agoGreat 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 4mo agoVery cool idea! Will try and add.
- tt_dev 4mo agothis was fun
- MontyCarloHall 4mo agoA 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. [0] https://woodgears.ca/eyeball/index.html https://woodgears.ca/eyeball/index.html
- mrroryflint 4mo agoOh wow - that is very cool. Thanks for sharing.
- harrisi 4mo agoJust 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.
- stronglikedan 4mo agoThis 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.
- kerblang 4mo agoOh 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.
- imzadi 4mo agoidk, 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.
- FinanceFreddy 4mo agoOh, this is actually fun! How about if you change the target every few seconds to add a bit of pressure.
- lbeyer 4mo agoSimple premise, oddly hard to put down.
- layer8 4mo agoThe 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.
- ehsangazarr 4mo agoReally fun! I am pretty much blind
- ehsangazarr 4mo agopretty fun!
- densekernel 4mo agohttps://eyeball.rory.codes/ https://eyeball.rory.codes/ I was 0.20% off on eyeball. Beat me: https://eyeball.rory.codes https://eyeball.rory.codes
- deleted 4mo ago[deleted]
- pravj 4mo agoI reached 0.05% and retired for the day. https://postimg.cc/MXBQqrXf https://postimg.cc/MXBQqrXf
- schuhwerk 4mo agoNice! Would be nice to see your progress over time (if you got better, also as a function of speed...)
- oastp 4mo agolove it, pulls you in after a first try)
- wolttam 4mo agoThe low contrast of this website hurts my eyeball
- Chaseraph 4mo agoWell I suck.
- mrroryflint 4mo agoI built it and still suck, don’t feel so bad.
- deleted 4mo ago[deleted]
- Mabusto 4mo agoI love these simple games that take 2 seconds to understand the rules. Off by 6 on my iPad by mis-clicking. Very satisfying!
- mrroryflint 4mo agoThank you!
- harrisi 4mo agoIt'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 4mo agoyes, 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 4mo agoIt 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)_/¯
- cdelsolar 4mo agoi got a 0.00% after 3 tries!
- Hugsbox 4mo agoI 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
- sandebert 4mo agoGot a perfect result for the first try. (Off by zero.) Not trying again. :)
- senectus1 4mo agoyeah i got an off by 1 and decided that was good enough :-D
- RAZKOM 4mo agoI thought I was going to be really good at this but turns out I'm surprisingly bad. Cool idea.
- ninju 4mo agoNote the "share" link doesn't share a specific challenge for others to try, which would be much cooler, instead it just shares to main page
- mrroryflint 4mo agoCool idea, thanks
- shashankqv 4mo agoThis is very cool and fun. Thank you.
- mrroryflint 4mo agoThanks!
- datagrasp-grcs 4mo agoVery cool
- baisampayans 4mo agoThis is wild. Got hooked into it pretty fast
- fspoettel 4mo agoWould love a time trial mode
- thedetailsguy 4mo agoSuper cool stuff!
- fortran77 4mo agoI got a perfect "off by 4" on the first try! I feel like I've accomplished something!
- tartoran 4mo agoFun. Got a streak of 4 and one of them was perfect (nearly .10% of target).
- gverrilla 4mo agoSuggestion: make timed tracks - like a sequence of 10 turns, within max 60/30/15s or something.
- furyofantares 4mo agoI find it very easy if it's near 50%, 10%, or 5%. 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.
- GearDev7532 4mo ago[dead]
- untitled-now 4mo agoI 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 4mo agoI 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.
- dennis3124 4mo agoLove how simple it is.
- jjenks1106 4mo agoreally cool! enjoy the simple premise but very satisfying
- iJohnDoe 4mo agoThis 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.”
- obomeretic 4mo agoI was 0.67% off on eyeball. Beat me: https://eyeball.rory.codes https://eyeball.rory.codes
- obomeretic 4mo agoI was 0.05% off on eyeball. Beat me: https://eyeball.rory.codes https://eyeball.rory.codes
- mavdol04 4mo agoIt'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%.
- efilife 4mo agovery weird comments from very fresh accounts under this post
- SugarReflex 4mo agoI 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.
- Kwouz 4mo agoIts cool man, i was playing for 1 hour, havent won yet
- Lucas12546 4mo agoI got 0.03%. I try my best.
- 0xchamin 4mo agocool game. I tried. would be nice to include a helper description around what to do. took me a while to understand the challenge better.
- sentacraft 4mo agoThis is fun! and I really love the clean and modern UX.
- mrroryflint 4mo agoThanks!
- _kbtz 4mo agoI was 0.43% away
