Houseguests will be given an image that contains a spot the difference puzzle. If you don't know what is then according to google:
Spot the difference is a type of puzzle where players must find a set number of differences between two otherwise similar images, whether they are illustrations or photographs that have been altered with photo manipulation.
You will have 10 minutes to find as many differences as you can. There will be at least 10 differences but I won't be telling you the exact number. You must use a paint type program to circle the differences on the 'edited' image. Red will be good.
If you circle a correct difference, you score a point. If you circle something that is not a difference, you will lose a point. The houseguest to find the most differences in the fastest time, wins the Power of Veto.
This is in sessions so you have 24 hours to contact one of the staff.
