Scratch Card

Players rub away a cover to find a prize or a friendly miss underneath, with the odds or the timing you set.

A Scratch Card is a card with a cover on top. Players scratch it off with a finger to see whether they've won. Studio lists it as Scratch Game. Here, Lindenhall's Seed Packet Scratch hides a £10 garden centre voucher, with a one-in-five chance.

The Seed Packet Scratch on three phones: the card, How to play? with the game details, and a scratched card showing the £10 voucher

Before you begin

Background Image

Required

The full-screen visual behind any game (wheel, scratch, reveal, quiz, and more).

  • Requiredexcept for instant reward and sign-up games
  • Size1536 × 2048 px
  • Aspect ratio3:4
  • FormatsJPEG / WEBP / PNG

It fills the screen from the top centre, with the title, the game and the button on top, and phones crop about a fifth off each side: keep text and faces in the middle.

Examples

Front Image (Scratchable Cover)

Required

The cover players scratch off to reveal the result.

  • Required
  • Size1200 × 800 px
  • Aspect ratio3:2
  • FormatsJPEG / WEBP / PNG

Use a fully opaque image so the prize stays hidden until scratched. The card is 3:2: a picture of another shape repeats across it.

Examples

Back Image (Branding Side)

Optional

The branded surface shown behind the scratchable cover.

  • Optional
  • Size1200 × 800 px

  • Required
  • Size1200 × 800 px
  • Aspect ratio3:2

It is stretched to the front image’s size, so keep both at 3:2: it then fills the card once scratched.

  • Size800 × 800 px
