You know what I realized today? If you win one of the hourly contests (the wager or the highest win ones) then you get the rewards you won counted in the next hourly win contest immediately

So in fact, if you just play once, and make sure you win once, you'll keep appearing in the hourly win until 20 other people win more than you. Pretty neat huh? Of course by second hour you will be out but I won 'free' satoshi in the next hour for placing in the 2nd hour that I didn't bet.
