Neat idea, but is this something you can actually be skilled at? Even if you know the game, and can figure out what trajectory the ball was on, it seems very hard to figure out exactly where on that trajectory it was when the photo was taken, given the high speed of the ball.

Couldn't you? It seems like if you were skilled enough you could figure it out by the reactions of various players in the photos with more than one or two people in them.

It's odd to see a casual game, with no other significance or meaning, in the NY Times. It would be great to see them using interactive tools to tell news stories more often.

They do that too. Like the story they did about the Philippine Coast Guard in the South China Sea.

Oh, damn. I think you've found a bug, sorry about that. I think it's expecting a touch event when it shouldn't be. Let me take a look at that. EDIT: should be fixed now. Apologies again, embarrassing bug caused by a last minute bug fix. The way these things always go...

Yep. Chrome on a Surface Pro 3. Doesn't react to click events, only worked if I actually touched my screen.

Re-opened to test in Chrome on Ubuntu (XPS13dev) and to my astonishment, touch events worked!

I'm one of the people that made this interactive - funny to see it on Hacker News! If anyone has any questions about it, let me know.

How long does it take to "hide" the ball per pic?

reminds me of bestofthebest's car raffle... since you can't really gamble in the UK, they do a skill based game that is exactly this... you buy guesses and then click where you think the ball is... the person each week with the closest guess to where a group of judges says the ball is wins the car of their choice

a group of judges? but... isn't there one objective correct answer?

John Graham-Cumming wrote an article about trying to hack a contest similar to this. I wonder if a similar technique could be used to find the ball on these images? http://blog.jgc.org/2008/02/tonight-im-going-to-write-myself...

I started to roll my eyes when I saw your comment because I thought, "the NYT made a fun web interactive with no-stakes and someone is pointlessly wondering if the answers are in the source code"...so now I realize what a reflection this is on how lame and limited my own thinking is :).

This was a great link...I've been casually brainstorming heuristics for detecting possible Photoshopping and John writes about exactly that. I'm going to walk through his algorithm using Python and PIL.

What fun is that?

What am I doing wrong? Clicking and dragging the "drag this" has no effect. Nothing moves or changes in Chrome 43.

Same problem: worked in IE (!) though.

Trying to triangulate based on where players' eyes are looking rarely works. In many cases, the goalie is looking in a completely different direction than where the ball is. I guess that's why they're getting scored on.

This is infuriating. I tried using where players were looking and it got me squat. Very cool though.

Yeah I found that the players' eyes were mostly useless but often times the composition of the photo is helpful. For example, if players are gathered on the right edge of the frame and there's a bunch of blank space to the left, the ball is likely over in the open area
