100% 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.

Congratulations, you may have discovered your unique talent! Now, about the monetization strategy ...

I guess “Australia-shaped cookie cutter” would be more accurate

I wonder, is a cookie cutter a kind of bent knife - or is a knife a kind of straightened cookie cutter?

"Maybe that was all preparation for slicing America in two using an Australia-shaped knife" one of those sentences I feel like no one has ever said before (/r/brandnewsentence material)

I don't think HN is the place for r/subreddithashtags

now if only the America vs Australia cut was on spherical (or ellipsoidal I guess) geometry rather than projecting both countries to a plane prior to slicing

I got 97% on the first part and was impressed with myself, but you're experience with design work is certainly the professional difference. That's impressive!

97% here too, with 6 out of 8 perfect cuts. Much better than I expected!

95pct, 4 perfect splits, did better than I thought I would

Congratulations, and here I was happy with my 95% :)

I 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

I did best when I didn't "overthink". I would briefly reasoned about the geometry, then stop once it felt right

I got 92%, I’m proud.

I did best when I worked intuitively and fast.

I only got perfect score on the donut/mug one... is this game trying to tell me something?

You are Homer Simpson and I claim my £5, Mr Cthulu_.

Err what are your pronouns, O tentacled horror of an old one (with a trailing ledge).

I got 98% The two I cocked up I spent too long trying to align edges and geometry but actually it seems us humans do have a pretty decent hard wired equal area estimator built in. The last one - AUS/US - should be really hard but I suspect that the results are pretty good.

I'd love to see the results for this. There is almost certainly a decent paper in it.

I got 100pc on the aus/usa, donut and mug, and a few others. Pretty surprised!

Good skills

100% over here, too. I used more geometric thinking at the beginning but of course that shifted into gut feeling by the end. Nice job!

97% (5 perfect). I don't know either. My guess is that most people are pretty good at judging what the half of something looks like. I feel like if the movement (on my phone anyway) wasn't as jerky/sticky I would have gotten one more perfect. I definitely had one that was very inaccurate (55/45) though.

Lol, I got the America/Australia one perfect too! That surprised me!

They seem to be fudging it a bit. In the first example with the circle, anything better than 45%-55% (as measured in my graphics editor) is reported as a perfect 50-50 split.
