That's interesting. But since we don't actually know whether there are infinitely many sextuplets (and certainly can't assume such sextuplets exist in a given range of values), doesn't that mean that it's possible to hit a difficulty with which no block will be possible to find?

gambling with bitcoins is pretty dangerous . I am always having one and one only rule, spend only what you can afford to loose when playing for money. However once it happened to me that I have put all in by mistake and didnt noticed that, I have lost whole deposit 160 dollars. Fortunatelly i made that winnings from converted ripples giveaway so my hard earned money was not at risk but because of my mistake I have lost free 160 dollars. So I suggest everybody to pay attention and never play when you are tired. Smiley Good luck people anyway.

I filled out the captcha and then pressed the "Get some bitcoins!" button.
If some bitcoins were sent, where were they sent? 
I was never asked to input a bitcoin address. The only input field I can
see in firefox is for the captcha.
