A scratch card (also called a scratch off, scratch ticket, or instant game) is a small token where one or more areas contain concealed information: they are covered by a substance that cannot be seen through, but can be scratched off. Scratch Cards are a form of gambling in Grand Theft Auto: Chinatown Wars.
The feature takes advantage of the Nintendo DS touchscreen and the microphone. The player can buy a scratchcard by dragging a scratch card of their choice to the Cash Register. The player can either scratch off the foil by using the touchscreen or blowing into the microphone.
In the PSP version, moving the analog stick will scratch the foil. The player can claim a prize by revealing a set of three winning symbols out of the six ones in the card.
There are five different kinds of scratch cards with varying rewards.
Note: If the weapon will replace a weapon of the same class, the player can confirm the replacement.
