The objective of the game is to try for the best five card hand that you can possibly get in which you have a Pair of Jacks or Better in the game. Any pair that is below the Jacks is not going to payout.
In Louisiana Double you have a 53 card deck, which is one of the differences in this game. The double card if shown can win on a payout and that amount will be doubled.
