I know I have posted this before, but I will post it again. ANY play can be parlayed. Estimate the odds on the other event to be parlayed. Put the amount of the parlay on the first game/prop. Take the entire amount (winnings + original bet amount) and put it on the second game/prop in the future. Of course, this means that two games/props that start at the same time can not be parlayed. But if you parlay anything in the future, you have already won the first half.
