1pic/day. I'll increase the rate when I some more people start playing.

@mem: there is one transaction visible in the transaction list now.

Glad to see you are still keeping this active/updating the pictures regularly. Keep it up! 

Done: https://apopheniabtc.com/txs.php

Of course it will only show transactions that happen after today. The older ones are protected by the privacy policy. The new PP states that data related to bitcoin transactions and paybacks are public data.

Which picture are you referring to, toothpicks? If you mean the one with Vulcan I only see one correct placed on it.

That's a good idea that has crossed my mind too. I'll need to change the privacy policy first to note that payback addresses and bet addresses will be public data. I'll do that as soon as I get a chance. I'll place a link in the [Other] section that will take you to a page with all the transactions.
Unfortunately there is nothing that can stop me from doing this. The pictures have to get into the system by a human (since they are unique pictures that cannot be found on the internet to avoid cheating with TinEye etc) so some human WILL ALWAYS know what pictures are in the system. Even if we had a system that you input pictures in batches of one hundred pictures each and then they are selected randomly, the human that inputs the batches would have a big advantage because he would be able to recognize the pictures much earlier than other players. Additionally he would know the exact answers. This has already been discussed a bit in previous posts in this thread, you may take a look if you are interested. To cut a long story, I can't think of any way to make this game provably fair. Of course this is not the first game that you have to trust the owner before you play. People have been investing time to go on TV games based on knowledge, meaning they trust that the TV channel will not cheat.


I was experimenting with various custom effects. The initial one was very different from this one. It would start doing random walks on the picture. Each random walk would paint circles and ellipses underneath it. The color would be a mixture of the color it was stepping on, the color of the starting point of the walk, a random color and the color of an offset pixel. Too bad I didn't keep one of those pictures. It looked like some terrible oil painting. The bad thing about this effect was that as time passed on, fewer random walks remained, and parts of the original picture were clearly revealed. It was too easy to recognize which parts were revealed and which were still painted by some random walk so in the end it wouldn't matter how I painted underneath the random walks. I could just hide parts of the photo and it would have the same end result, just not so fancy.

The new effect is based on the idea of duplicating the picture, offsetting the duplicate by some amount on X and some on Y and then applying that "triangle" effect. The triangle effect basically replaces every pixel with a triangle. It's done in two steps, first step places opaque triangles everywhere creating a confetti effect. Then on top of that I place a few more triangles that are transparent to create an effect that looks like broken glass or something. As time passes triangles get smaller and the offset picture is moved gradually back to it's starting position. I might make some changes these days to the algorithm though.

Very very interesting


Can you show previous bets, timestamps and txids please.

Also I dont see what prevents the site from collecting their own pots once big enough as you would already know the answer.

How do you generate the modified pictures ? its a very interesting effect, is it repeatable for each picture (like a visual hash)?

i thought i guessed it right... someone got to it before me i guess?

Please tell me that someone can answer this one. :-D It will expire in 6 hours. The pic is completely clear.

That would be pretty awesome, because currently it's constantly the same distortian (as far as I see generally), and you basically can't see anything the first 24 hours.

New pic!


Would you guys be interested in having multiple ways to distort an image? Each image getting distorted randomly by one of the available algorithms?

think i need new glasses  i'm wondering how you did solve that

Dang it, someone got to the text one before me lol. Good job!

Nice work uncaer9. I was wondering why people hadn't solved that one yet. :-)

Just solved my first picture - "spare parts"  
I really like that website though I've lost more than I won.

1. The player that got the hot wallet contacted me and offered to return it. :-) How cool is that??

2. I added a new picture. It's a person. The starting pot is 6 times the bet. It's quite high compared to older pictures AND it has a bonus carried over from the expired picture. So it's a pretty high starting pot: 0.04375BTC for a bet of 0.005BTC (x8.75). And as I said yesterday I also increased the bet fee from 40% to 50% (in other words my breaking point is somewhat higher now but I think it's worth it).

This is will expire in a few minutes!

He got 0.334BTC because of the bug. Plus the pot for the picture of course.  

Really stupid bug... It took me some time to find what was really wrong. It turned out that while the whole site works on integers for prices, there was a point the price was not cast to an integer. So the value 0.00875 (his bet) was supposed to be converted to 875000 but instead it was some value very close to that which caused some comparison to always recognize the bet as something that was just paid and then, because the picture was already solved, the site kept returning the bet back to him over and over every 5 minutes until the cold wallet was emptied.

EDIT:
Tomorrow when I'll post new pictures, the fee will be 50% (it now is 40%) but the starting pot will be even higher: 6 times the bet (it now is 4x). This should reward more those that take their chances earlier.

Ouch, how much was in it? Great for the person who won though =P.

Some arithmetic bug caused the whole hot wallet to be gradually sent to the player that answered the Vera Miles picture.

No worries though. The hot wallet had little money in it, the bug is fixed and I'm refilling the hot wallet in a few minutes. :-)

Higher would be pretty awesome.

The text one was harder than I expected. It took ~3 days just to reach the point where I start to see the text. Sorry for that I'll keep it simpler next time. Consider this picture to be added just now. ;-)

Oh and I added one more picture:


BTW do you people want higher or lower bets?
