Is the giveaway still on?
Yes, this week is the last of the current credit promo for incorrect predictions. I am considering possibly doing a new, different promotion in the weeks ahead, but that's as of yet undecided.
And can someone help me understand how the game is played?
I read the OP but I am a bit confused.
Can someone explain it to me?
Thanks
Sure... First read this post (#49 in the thread, probably middle of page 3 if you use standard view settings) -
https://bitcointalksearch.org/topic/m.11188194 - as I did a little bit of explanation there which may also help.
Once a week there is a block that comes out usually early Friday afternoons EST, which carries the transactions for NastyFans distributions. This block is the one we use for the contest, and the links to the block are posted in the thread as confirmation as well.
What we are doing with this is a simple guessing game - you make a prediction on that last character in the block hash (post #2 at the beginning of this thread has some details on how to look it up, etc).
That last character can be any letter from A - F, or any number from 0 - 9.
There are two ways to make your prediction:
1) In the OP of the thread there are addresses corresponding to either a single letter, single number, or groups of letters or numbers. To make your prediction, you simply send the correct amount (between 0.01 and 0.02
BTC) to the appropriate address
2) There is a website for this -
http://keno.nastyfans.org - which has QR codes on it, which can be scanned by any mobile device and if you have a wallet associated with that device it will fill in all the details for your wallet app, making it easier.
Each type of prediction has a different payout - from 2:1 for all letters A-F, to 4:1 for 3 letters/numbers, to 10:1 for a single letter or number.
You can make as many predictions as you'd like, but only one incorrect prediction will qualify for the promo.
The payouts are done by looking at the payment addresses in the blockchain, and sending back to them. Unless wanting to qualify for the promotion, you do not need to post that you made a prediction in the thread if you want to remain anonymous. However, you need to post like everyone else if you want to qualify for the promotion.
I hope this helps explain it a bit more for you. Please let us know if you need more info.
