Prize Image Specs – must be in a square format – 300×300-pixels is the best size. Use png and GIFs with or without transparency and jpeg images.
Scratch-Here Pad Image Specs – must be a square format – 300×300-pixels is the best size. Use png and GIFs with or without transparency and jpeg images.
Logo Image Specs: there is no size set in stone; we recommend a max image area of 600×200-pixels, so it displays nicely and big on desktop views and reduces in size well on mobile devices. You may need to play around with this and view it on your cellphone and desktop computer to determine the best size and fit. If the logo is too deep in height, it pushes everything below it, such as the scratch-here pad, prize image, and claim prize. A logo that may be too deep in height may push the claim prize button too low and out of view for your players and cause confusion and game abandonment.
Background Image Specs: First, NO high-res images are allowed; they may cause the campaign not to work or display correctly. Keep the file size below 200k. Vectors with abstract imagery work best because the background images are NOT responsive and stretch in and out depending on the monitor size. A 1920 x 1080-pixel background image is a good starting point, and view it on both mobile and desktop monitors and make any size adjustments as needed.
Mobile-Only Background Image Specs: If you have the type of game that players will only be on mobile phones to play and want a photo to display realistically, you can try a background image that is 1080 x 1920 pixels.
