- dfxm12 3y agoThe game should remind you in some way which round was which when it shows you the score at the end.
- blamestross 3y agoI wish there was a leaderboard or percentile you could see without making an account.
- function_seven 3y agoI nominate your comment as the start of the leaderboard. :) I got 91% overall with 3 perfect splits.
- bee_rider 3y agoYeah I’m quite curious what a “good” score is, I thought going into it that it’d be quite hard, but I got 97%, 5 perfect.
- _ache_ 3y ago94%, 6 perfect cuts. God, I mean, we (humans) are pretty good to cut things in half !
- pjm331 3y ago96% accurate, 4 perfect
- hellosunschein 3y ago80% accurate, 2 perfect!
- latexr 3y ago93% accurate, 4 perfect.

- RheingoldRiver 3y ago95%, 4 perfect. Worst score was 42-58, on the maps one.
- deleted 3y ago[deleted]
- mhandley 3y agoGot 99% perfect, 6 perfect cuts, on my first attempt. A couple of the perfect ones, I thought I'd be close, but was surprised to be perfect.
- DistractionRect 3y agoI got 98%, 6 perfect cuts on my attempt. The bird and the plus tripped me up. The bird seems the hardest based on the comments
- hatthew 3y agoSame. The only one I missed was the donut/mug.
- makr17 3y ago92%, 2 perfect.
- LesZedCB 3y ago96%, 5 perfect. i went by 'balanced vibes' most of the time.
- bee_rider 3y agoThere were some that had exploitable geometry, but I was surprised to get some perfecta on vibes alone. I think, the star one in my case.
- somethingAlex 3y ago95% 4 perfect
- hysan 3y ago92%, 4 perfect A leaderboard would be pretty cool. I had tried this a few times and it's the last two that get me. Curious to see how good people are at those.
- rojeee 3y ago96%, 5 perfect cuts!
- patriksvensson 3y ago96%, 3 perfect!!
- all2 3y ago92%, 3 perfect (I got the bird perfectly, to my surprise. Australia/US I bodged completely.)
- hindsightbias 3y agoI think they should invert Australia, would make it easier.
- bmacho 3y agoIf anyone wondering on these scores, it is possible to go below 90% ...
- latexr 3y agoJust tested, and it is possible to get 0%. Yet the message will still say “not half bad!” I guess they’re technically correct, it was completely bad. https://i.imgur.com/ESLd1WV.png https://i.imgur.com/ESLd1WV.png
- abbadadda 3y ago95%, 6 perfect cuts (cut the 2nd one really terribly)
- airstrike 3y ago94%, 4 perfect. I feel like the score should also be timed... In hindsight I should have spent more time on some of these!
- RivieraKid 3y ago97%, 4 perfect.
- V__ 3y agoI was able to get the first five exactly with a bit of luck and think with a bit of thinking it should be possible to always land near 1% or 2%. But is there a good way to cut the cup, bird or map one without calculating it? I got lucky and got the cup exactly but I don't think I could get close without just beeing lucky on the bird and map onea.
- mhandley 3y agoWith the cup, I moved the doughnut up from below, and just eyeballed when the area above the midline of the cup equalled the area in the hole. Turns out I can do this fairly accurately.
- latexr 3y agoThe cup is symmetrical and so is the donut shading, so the trick is to flip it on its head: instead of cutting the cup with the donut, cut the donut with the cup by ensuring either the top or bottom half of the donut overlays the cup. With that line of thinking I get a perfect split every time. No insights to share on the other ones, though.
- karaterobot 3y ago100%! Not sure what this measures, but I've spent decades trying to gauge whether a design is one pixel off, or if some minor change has affected the layout of something. Maybe that was all preparation for slicing America in two using an Australia-shaped knife.
- irrational 3y agoI had 99%. I was barely off on the bird. After the bird I said screw it with Australia and the USA and barely tried and still got 50/50. LOL
- xyzal 3y agoCongratulations, you may have discovered your unique talent! Now, about the monetization strategy ... :)
- jayknight 3y ago100% too, but I was shooting blind for the last few. Not sure if I just got super lucky or if the brain is better tired think at setting that.
- thewarpaint 3y agoI guess “Australia-shaped cookie cutter” would be more accurate
- taberiand 3y ago
- darknavi 3y agoMy main take away is that humans are pretty good at eyeballing 50/50 splits.
- esafak 3y agoHumans are wired to detect unfairness. I bet numerous other animals are too. https://parentingscience.com/babies-expect-fairness/ https://parentingscience.com/babies-expect-fairness/
- deleted 3y ago[deleted]
- amelius 3y agoYeah, just imagine the shape is a piece of a pie.
- esafak 3y agoKids have birthday cake all the time. Believe me they're practiced. Though they are sensitive to more than the size; they also want the slices with the nice colors and toppings :)
- yard2010 3y agoThis is a great read. While I'm not 100% sure the method (looking time) is the best, I love how the results are consistent across many experiments. Ofc, the key take away is that it doesn't really matter because personal experiences take over the inherent human "hard wiring".

- aidenn0 3y ago
- v3ss0n 3y agoI hope nobody make a captcha out of this, I failed hard
- bee_rider 3y agoI think it would be a bad captcha—it is impressive how good some people are at this, in the sense that it is surprising that people can just eyeball areas very precisely, but a computer could really easily count the pixels.
- ulnarkressty 3y agoIs there any proof that doing this regularly helps with anything? Not necessarily making one 'smarter', but at least keeping dementia at bay for older folks? All I could find is that playing board games seems to help with cognitive decline, but this could also be the social part of it.
- qd011 3y agoPhysical exercise is the thing that prevents cognitive decline the most.
- fidotron 3y agoThis was probably the best thing in the latest b3ta newsletter (one of those bizarre Barley-esque hangovers from the British internet circa 2004) https://b3ta.com/newsletter/issue880/ https://b3ta.com/newsletter/issue880/
- gizajob 3y agoAlright. Fat-arms.
- rahimnathwani 3y agoThis reminds me of NTK.
- dsego 3y ago95% Accuracy, 3 Perfect cuts
- deleted 3y ago[deleted]
- topoftheforts 3y ago96%, really proud of that
- chrislan815 3y agoI was 93% accurate! ⬜⬜ Can you do better? https://www.brilliant.org/challenges/halfsies https://www.brilliant.org/challenges/halfsies I win
- deleted 3y ago[deleted]
- sebzim4500 3y ago98% I don't buy it I'm not that good.
- ezconnect 3y agoI was 96% accurate! ⬜ Can you do better? https://www.brilliant.org/challenges/halfsies https://www.brilliant.org/challenges/halfsies
- amelius 3y agoSome time ago there was this other game where you have to construct geometrically various points, lines, etc. Does anyone remember the name?
- iamwil 3y agoHow is the area computed? Are they counting pixels? Constructive solid geometry, and then some sort of computer graphics algorithm for area? Or is it an SVG, and they're doing some sort of complex integral? (<--probably not)
- salamanderman 3y agoI'd guess SVG. It's not a complex integral. They can do a boolean intersection in SVG.
- dvh 3y agoThey are probably counting pixels but you could for example use destination-out compositing operation on canvas and resize to 1x1 pixel and read brightness of single pixel.
- michaelkaufman 3y agoI had to check. It's Next.js /React and the images are all CSS using Chakra. Just looking at the payload, it's sending the byte sizes which tells me they are counting bytes and checking for the difference. Pretty clever.
- gowld 3y agoTouch doesn't work on Firefox Android?
- DistractionRect 3y agoJust played through the first 8, touch works fine on Firefox for Android on Pixel 4a, ver 118.2.0 in About Firefox pane.
- ad404b8a372f2b9 3y agoOnly tangentially related: There was a great talk about Brilliant's custom diagramming language at last year's StrangeLoop conference: https://www.youtube.com/watch?v=gT9Xu-ctNqI https://www.youtube.com/watch?v=gT9Xu-ctNqI
- shthed 3y agoIs this meant to work on desktop with mouse?
- KyleBerezin 3y agoWhat a great ad. Its like its trying to sell brilliant subscriptions via the shareware floppy model.
- discardable_dan 3y agoMany people are saying they did very well, but if I were trying to sell a service I'd tell people that same thing. "Sure, you did a lot of these perfectly, want to do more games that will feel satisfying" seems like a great onboarding strategy.
- manbitesdog 3y agoI wonder if the mug & donut reference was intentional
- Titan2189 3y agoWhat was it in reference to?
- JDEW 3y agoThe old joke that mathematicians can't distinguish a donut from a coffee mug (because of topological "equivalence"/homeomorphism) [0] [0] https://en.wikipedia.org/wiki/File:Mug_and_Torus_morph.gif https://en.wikipedia.org/wiki/File:Mug_and_Torus_morph.gif
- wrsh07 3y agoTo a topologist, a mug and a donut are the same shape (can be deformed to a torus without changing topological properties)
- kweingar 3y agoCould be a reference to Dunkin' Donuts
- RheingoldRiver 3y agoThere's no way it wasn't, I laughed when I saw it
- deleted 3y ago[deleted]

- kazinator 3y agoI'm not able to move the white shape. This might not have been tested on desktop Firefox.
- enlightens 3y agoFWIW it worked for me with Firefox 118.0.2 on Windows 11
- kazinator 3y ago118.0.2 on Windows 10. However, I figured it out; interaction with Dark Reader extension.
- mon_ 3y agoTurning off the Dark Reader plug-in made it work for me on FF
- TiredGuy 3y agowow, I was pretty proud of my 88% but then I saw all the comments here Really neat way to advertise Brilliant. Reminds me of Google Doodles or something.
- swimwiththebeat 3y ago92% with 4 perfect cuts (messed up badly on the easy 12-sided shape). Don't know why, but it was a strangely fun exercise. "Brilliant" ad too (pun intended :D)
- gordon_freeman 3y ago93% w/ 5 perfect cuts here. :) I now trust my 'visual intuition' more after playing this game! fun experience for sure!
- robbyking 3y agoWhat's interesting is I found that the less time I spent on an estimate the more accurate I was. (5 perfect cuts, 97% accuracy total.)
- phatfish 3y ago5 perfect as well (95% total), what does this mean??
- gordon_freeman 3y ago5 perfect gives you 100% on those 5 attempts but then your overall % is calculated based on at what margin you missed out on other attempts. ex: if you got 42% instead of 50% in an attempt then that would impact your overall %.
- atulvi 3y agoDoes this use Computational Geometry?
- salgorithm 3y agoI wonder if growing up with similar-aged siblings gives you a natural advantage at this game.
- honksillet 3y agoThat’s a fun little web game. But isn’t brilliant supposed to be educational? This is not at all.
- saithound 3y agoAs far as self-study is concerned, it is closer to entertainment than to education (and ultimately just an ad for brilliant.org). But it is a great educational tool for e.g. a classroom or a math circle led by an experienced mathematician. Discussion about why these puzzles are solvable and when, and how you can build your own, naturally illuminates concepts such as the intermediate value theorem, simply connectedness, and even measure.
- postalrat 3y agoI bet if you did 100 of them you would get pretty good at it.
- cableshaft 3y ago94% accurate with 4 perfect cuts. Biggest screwup was the last one, the rest were very close. Fun game. Could easily see a more robust version of this with 50-100 levels doing pretty well.
- sakras 3y agoFunny that this comes up - a lot of times while watching YouTube I'll fidget by trying to highlight exactly half of the title. I check whether or not it's half by dragging the highlighted section over the other half. Glad there's a game for this now!
- hatthew 3y ago> check whether or not it's half by dragging the highlighted section over the other half This is genius, I'm going to do that from now on (and have more reason to be annoyed at the inability to get a perfect split on discrete characters).
- RivieraKid 3y agoAs someone who's interested in UI / UX, I have to say, Brilliant is one of those companies whose design is basically perfection.
- gpvos 3y agoWould be good though if they had tested it with slightly older desktop Firefox. FF 113 on Linux, which really isn't that ancient, and I can't move the white area.
- murphyslab 3y ago98% and 6 perfect cuts. I blame sibling rivalry.
- matthewhartmans 3y agoCongratulations! This is really well done - I love the concept and the UX! Beautiful job friend!
- stevage 3y agoDid not seem to work with Firefox mobile for me. All I could do is continue without dragging. Turns out you get a score of 26% that way and a rating of "not half bad".
- jheriko 3y agointeresting, i got a few of the trickier ones a littler off... I was 95% accurate! ⬜⬜
- thecarissa 3y agoSuper cool!!!
- SuperNinKenDo 3y agoI was kind of surprised how good I (and a quick skim of the comment shows, most other people) are at this. Conventional wisdom seems to suggest that people aren't terribly good at comparing volume when shapes differ, but perhaps that's only in three-dimensions. Edit: 98% btw.
- Rallen89 3y agoThere is a good amount of gratuitous rounding tbf +-5% at least
- botanical 3y agoI can't believe I got perfect on the Mug and America ones! 88%
- furyofantares 3y agoIs it fudged somehow? The number of perfect cuts we're all getting feels very unlikely to me.
- nearbuy 3y agoThey do appear to be fudging it. At least for first practice example with the circle, it appears to show a perfect 50-50 split when you're up to 5% off (in area) in either direction.
- furyofantares 3y agoI'm shocked at how little skepticism there was in this thread. I verified this too. Took a screenshot of a perfect score on the circle, flipped it, and overlaid it. I was 10+ pixels off.
- lifthrasiir 3y agoSix perfect cuts and two 53-47 splits (#6 and #8). For some shapes I was pretty analytical; for example #2 has 21 small squares, so I tried to first cover 11 squares then move it upward by a fifth of the unit. This approach apparently didn't work well for irregular shapes.
- meatjuice 3y ago96% accuracy 4 perfect cuts I'm a halfsize hero
- gytdev 3y ago3 perfect cuts. Only 1 cut below 95%. Seems a bit off
