Contribute

Help complete the record

A new chip, a better photo, a correction or a story about a casino. Every contribution is checked by hand and credited if you want it to be.

Tips for good photos

  • Shoot front and back, straight on, in daylight.
  • Use a plain white or grey background.
  • Fill the frame with the chip and keep it in focus.
  • If a chip has UV marks, a photo under UV light is a bonus.

What happens next

We check each submission against the guide, add new chips with a catalogue number, and update entries with corrections. If we have questions we will email you.
