how to participate in this program?
I tried to puzzle, but I can not give up this picture
Allow me to help answering this; to participate on this game and winning it, you simply only need three things: your time, your logic, and an account on certain sites (this far, they're yobit and betcoin.ag although the admin said he might want to broaden his selection and add sites other than yobit).
The puzzle are given once a day (sometimes twice) by the admin at a random time. Once the puzzle posted, you will race with other users here to find the correct solution as well as being the fastest because once someone find the correct answer, he'll redeem the code and anyone who try to claim after that will only get "code was activated on..." or similar things like that.
How do we know that we have solved the puzzle correctly?
Well, (suppose the puzzle was yobicode) just go to
https://yobit.net/en/yobicodes, replace the symbols on the puzzle with your answer, then click claim. If your answer is correct, you'll get "code is successfully activated", congratulation and don't forget to post here to tell other people here that you've activate it to save other people's time trying to solve what was already solved. While if you're wrong, you'll get "incorrect code" and you'll need to re-think.
Hope that helps.
