Incident: PVC coating on a stickerless cube

Status: Resolved

3d 3h

WesternChampionship2019

Incident description and resolution:

A competitor used a stickerless cube with a "PVC coating" on each colored part. The puzzle was accepted at the competition.

Similar cubes with non-transparent (black) stickers have previously been allowed, and the WRC has concluded that the PVC coatings do not give the competitor an advantage that Regulations 3d) and 3h) are meant to prevent.

Therefore, the WRC has decided that it is reasonable for these puzzles to be permitted.

The WCA Regulations will be updated to clarify this.
