The most effective strategy for winning scratch card games is correct money management. The player must decide in advance how many games he wishes to play and how much money he wishes to spend.
The player should purchase cheap cards so he has the chance to play more games. More games equal more winning chances. Cheaper cards typically offer better odds than more expensive cards, but the payouts are relatively low.
Some scratch card games offer jackpot cards that can reward up to several million dollars, but the winning chances are extremely small. The player should cap his jackpot scratch card purchases at about 10 to 20 percent of his total purchases.
If playing online, be sure to always claim the offered scratch card bonuses. Many online casinos provide additional money for free for signing up and depositing.
