Well, when it comes to the 10 euros bonus amount it's all demo... I created a plane and reached over 10k experience points, but it looks like we should do it every day, a new plane and those who make the highest wagering with demo money can win some cash prizes. At least that's what it looks like, but after yesterday's experience, I doubt it really happens, I should play all day actively to be in the top 100... so I don't plan to test it.
I guess it would be much simpler and easier for us players if OP is active here, at least he would clear some doubts we have and we would play it without fear of being disappointed after playing.
Oh I don't think I've ever explored the planes that far but yeah, I'd be making the same decision as well considering the uncertainties. I honestly thought OP would be active here esp after sig campaign interest, but it's been awhile since their last reply...
They should also improve the demo gameplay and add some guides so folks can know the exact situation. I'm pretty sure non-bitcointalk members (people in genral) are also confused.
