All scratching games are based on the sames principles. Players buy a card with zones they have to scratch in order to reveal a text or a symbol hidden under the film. The player usually has to find a specifical combination of symbols to win. His winning can depend on the combination he found : money prizes are written on the card for any winning combination. For other sorts of card, he will have to scratch another area to find how much money he wins. His prize is paid immediatly : he doesn't have to wait for a draw. Prizes are quite small. That is the reason why players often buy other scratch tickets with their earnings.

There are lots of scratching games on internet. Some of them are free with small gifts.
But you can also find scratch cards in online casinos like Everest Casino or Intercasino, but not only. With one dollar you can win up to $5,000. They are as easy to use as real ones.
