I got friend of mine way of play I do not know how good is but he says wins with it..so what he does as I undersood is s numbers coming he notes what street they are…say comes 1 then he cross count 1(as 1 is street 1) and streets 6,9,  next  number say is 10 he crosses count 4(as number 10 is street 4) and streets 12,4   â€¦he tracks it until are 4 left uncrossed and bets actual streets till all hit…have not tested it as I am at work…hope is good
