Where was it taken?
I'll gradually rule out entries.
Close time will be extended if the correct airport is trading less than 25% or it is not in the top 3 options.
I think this is a very good market concept.
But it just doesn't work in its current form. You are spending three hundred to create the market but it's solvable with only one guess. And it's actually so solvable in one guess that it almost doesn't make sense to do anything other than brute force Google until you find it.
(I don't have a solution, but I hope one is found)
I guess I would do something like this (purely suggestion):
This is kind of Manifold plays Geoguesser. Lean further into. Take a random streetview image without clear giveaway clues and have people try to identify the continent first (using your idea of slowly eliminating incorrect answers). Then once the correct continent (or region?) is above a certain threshold you confirm it and add the countries, and repeat.
@JoshuaWilkes The last time I did not add any of my own options, no one submitted any. Though maybe it could work now.
Okay so probably the next difficulty level could be to show only a small part of the image, or alternatively something unlikely to be shown by a google search (airport toilet, airport security, airport ground marking or signage, i don't know), or simply to allow people to submit airport (so that it is not possible to go through one by one - so its also cheaper for you)
@bohaska I think it's pretty good. You cnould even use only the right (or left) half to make it harder (but don't combine no-option and half picture, that's probably too hard)
On the other hand, I'm been trying out making GeoGuessr type question, and people seems to have insane locating skills so...
