great news! keep the good times rollin'

now a technical question: i am not familiar with some of your special flavours of sng:

what are the rules [or where can i read it, to save your time explaining] about:

top pair / overpair / two pair / trips / set / straigt / quads / straight flush sng's?

i love sng, but how does this works? whoever hits the said combo first, wins? what if they blind out, etc.?
