I gotta say bitcoininformation that I hate that puzzle slider thing one must solve in order to get a payout.
Just when I just about have all the pieces in their proper places it either randomly shuffles them around
or it times out.

I have been avoiding your site recently due to the time it takes to get a payout...
Really? Well, I will increase the timer then. Just try it out a few times and refresh before it times out to start again

The puzzle is a straight line (so all the pieces are in one line), but split up into two. So it acts differently then you might think. I hope this helps you :3
EDIT: Increased the timer to 1 minute. That should be more then enough.
Sorry, still way more annoying and way more frustrating than doing a regular captcha.
It was kinda fun and interesting the first couple times I tried it... but that gets old fast...
I won't be using it but if you find others like it then keep it there I suppose.
