What is the function of "proof of purchase" Token?

I guess they may request it if ever you need support for your games. Such as missing pieces...

I was wondering the same thing myself.

I thought they don't sell extra/spare pieces….?!?

thank you…………..

Joey, sometimes a carboard sheet will be misprinted, or components are missing from the box. That's when you email them and the proof of purchase lets them know you actually did buy the game

I just figured it was a gag.
