Have to revive this old thread
These are actually quite fun. They had 5-table SNG's of these on the Poker Room network. Played three of them and finished in the final table twice - in one of the games I was in the big blind at the start and then immediately moved to another table to pay the BB so I had no chance.
Sucks though that they only pay to the top-three out of 50. I could never get enough chips to get to the money, and it gets quite tough when short handed and the blinds rise every three minutes.
I guess its not too surprising that most of the players aren't particularly skilled, saw so many players limp for a third of their stacks and then folding to a raise.
