The graphical recommendations included in this guide are game-specific. You can find general recommendations for backgrounds, logos, and other images here.

Required assets are marked with a star*

Dimensions are listed in pixels, width x height.

Maximum file size: 700kb

File types: .png

Shell image*

This is the cup or other container that hides the item the player has to find.

  • Number: 1

  • Recommended size: 175 x 250

  • Maximum size: no maximum, but the images will resize to fit the width of the game (default 330px wide on desktop)

  • The same image will be used 3 times.

  • The same image will be used on desktop and mobile and will automatically downscale to fit the width of the screen on mobile.

If you want to design a cup-shaped shell image, you can use our .psd template.

See how to change the pattern on the cup here.

Hidden image*

  • Number: 1

  • Recommended size: 80 x 80

  • The hidden image should be designed to "fit" inside the shell, so make sure it is no more than 50% the width or height of the shell image.

  • The image can be designed with a shadow, to make it more realistic.
