Instead of spending time on free BTC sites, which is nice but you'd be getting paid more for doing almost any job in the world, why not use your guessing skills to earn some BTC on Apophenia?
Currently the payback is way more than 100% which means that, on average, for every bitcoin played the site distributes back more than 1 BTC. So, yeah, on average, I am still loosing money but I hope this will change as more people get in. Until that time why don't you take advantage of this?
Here is the site:
https://apopheniabtc.comThe minimum bet right now is 0.004฿ and if your guess is correct you will get 0.026฿. (Usually those numbers are both a little bit higher)
You can read all the rules and stuff on the site but the general idea is that your are trying to guess a distorted picture. The picture gradually gets less distorted so if you don't guess early someone else will guess and you'll get nothing. If you guess too early chances are that you won't guess correctly because of the distrortion. Most pictures also have a hint so make sure you read that before you guess.
There is only one picture on the site right now (I regularly keep 1 or 2 pictures open):
The hint says: "What's the text saying". This means that this picture is something like a captcha. Somewhere behind the distortion is some piece of text. You have to type what that text says as an answer.
There are other categories of pictures: movies, actor names, video games, objects, places, animals. Anything goes. Also some times I post hintless pictures where you have NO IDEA what the picture shows, those are much harder to solve but having your mind free to guess is fun cause the apophenia effect kicks in badly and you see completelly different stuff. :-)
Also, Apophenia has a referral program which could earn you a few cents. When someone visits the site using your referral link, you get to earn 5% of their betting fees (as long as they don't clear their cookies or change browser, they are marked as YOURS).
