Personally, I like Miss Robin's spell which is located on the link below. I have had many clients that have done this with success. As for the products I like pay me, and lucky 13 for lottery games.
Here is a list from http://www.luckymojo.com/gamblersluck.html
Fast Luck -- dress hands before playing slots, keno, bingo, races, lotteries
Three Jacks and a King -- dress your hands before playing cards or video poker
Money Drawing -- dress your hands and forehead before playing
Lady Luck -- for dice players; dress both your hands and the dice
John the Conqueror -- dress your money and carry a dressed root in your pocket
Lucky Mojo -- an all-purpose lucky oil for love, money, or games of chance.
Lucky Hand -- dress your money and hands before playing cards or video poker
Money Stay With Me -- dress your money to make your stake last loner
Pay Me -- usually this is employed to force someone to repay a debt that is owed, but it can also be used to force a casino to cough up the cash, as you will see below in "Miss Robin's Lucky Gambling Spell."
Lucky Number -- for playing the lottery, bingo, or any numbers-based game.
Good Luck -- an all-pupose luck formula for gambling, love, health, and general good fortune.
Lucky 13 -- used as a "house dressing" to prepare the rooms where folks gamble; can be used by the "house" or by players to gain an edge.
