Hey,
There was a webpage, where you could buy a seat out of 8 at a table, and wait for others to do so as well. When first row is filled, you are pushed down to the second row, where is only 4 seats. If the first row is filled again, you are pushed further down to a row where there are only 2 seats. If the first row is filled again, you will be on the last seat in the last row. If first row is filled finally, you are rewarded with 7-times the money buoght in. It can be either 0.001, 0.01 or 0.1 BTC.
Site was down for a couple of days, but now it is back in business!
Come, check this out!
