This is a "Matching Images" competition. It is in no way meant as a serious competition, more a fun event just before Christmas. Each club turns up with 30 images.
Basically, Club "A" projects an image, Clubs B and C then have 30 seconds to display a "Matching Image". Matching, is a very loose term, Club A display a Picture of a cow, club B then shows a Chair. The judge may decide they match because they all have 4 legs. Simple, and Fun. Each round there is a point for best image and a point for best match. No image can be used more than once.
Unlike most other events that including judging, audience participation to help the judge decide is encouraged.
