I entered them all, it played an ad via the youtube clip the first few comps I entered and the word was displayed at the bottom of the ad after 5 seconds or so. Now the videos are just the codes for me, must have watched all the ads :p
Certainly unique, had never seen it before either.
Pretty sure i watched like a 3minute pepsi ad waiting for a code haha, i'll try again maybe. Even tried audio code and i couldn't understand half of the letters either..
Edit: Managed to enter the $1000 one as it just gave me 2 words straight out.
Edit2: Kept refreshing the $500 one and it eventually just gave me 2 words to enter as well.
Finally!
That has to be the worst captcha type thing ever. It's meant to tell you some code while you watch an add, did anyone see a code?
