I know this is not a lottery like my site and hence it cannot use a method to select a fair winner. From what I know, the winner is the one that give the correct answer (similar by 90% to what you set) within the shortest prior of time. The loophole (to the participators) here is that there is no way to determine who give the correct answer first.
It is fair. There is a way of knowing who is first. How is there not a way? Simply. The first person to solve the riddle and enter their BTC address is the winner. And I am able to determine that.
Does it require deposit before we can participate to solve the riddle? I love riddles but paying for this challenge is stopping me trying it. I can get lots of free riddles now a days.
You win BTC for solving riddles. Therefore there is a 0.50$ deposit fee but that just goes towards the pot.
I love riddles, especially if there is a BTC prize attached!
What if instead of doing it the way you are now, you created riddles where the answer was actually a brainwallet? That way you wouldn't have to worry about who answered it first, or if they answered it with 85% correctness. They would have to answer it exactly right, and whoever swept the private key first would get it.
I'll think about that idea but for now I'll most likely do this for now. Its a good way to determine who won and I know exactly who won first.
