my local guys have always payed this type of parlay at 9/1. for example a $100 bet in which all teams cover pays $900. two teams cover and one team lose you get paid a paltry $60.($300 -$120 -$120). and if two teams fail to cover you lose the whole nut which equates to $360 per every $100 bet. understandlbly this is based on a parlay with "juice" attached. i'm sure this bet might be a tad bit different if your guy plays it without the vig, but the math is pretty much the same. personally, i'm not one to play these, but i have dabbled with them with a tiny bit of success. and to add if one of the teams pushi'm reasonably sure the bet might, or should drop down to a two teamer, but i'm not quite sure of that. it has never happened to me. i hope this helps.
