# Default Graphic Customisation for Scratch Cards

###### Overlay image

For the scratch Card app, the **Default scratch card overlay image** refers to the image that users will scratch away to reveal whether they have won or lost, or to reveal their prize. 

###### Underlay image

The **Default scratch card underlay image** is what users will see when they “scratch” away the overlay if no **Custom scratch card underlay image** is included for an item. Therefore if you want to use the same underlay image for every eventuality, you can optimise your time by just including it here. 

###### Scratch format

The scratch format setting allows you to define the shape and orientation of the scratchable area on the card. You can choose between landscape, portrait, square, or circle formats. This offers flexibility to better align the scratch area with your design, branding, or promotional goals. 

###### Multiple Scratch Options

* **Number of Cells to Scratch:** Define how many areas on the card a player must scratch before the result is revealed.
* **Number of the Same Prize to Discover:** Set how many identical prizes must be revealed for the player to win.
