Rule 100 was an idea that I had in December 2011. Basically, it is a free monthly scavenger hunt competition that anyone can enter. All members are searching for the same 100 items, and when they find one, they take a photo and upload it. At the end of the month, the member that has found the most items is crowned the winner.
After having the idea for Rule 100, I created a thread in the forum that I frequent (football365.com) and was impressed by the feedback received. The reaction was very positive so I dedicated all of my spare time over the following six weeks to developing the site.
On January 14th 2012 the first hunt went live and within one week, I had received over 85,000 page views. Feedback from the football 365 forum has allowed me to add several improvements that will ensure that future hunts will be even more fun for everyone, these include the creation of 'Mini leagues' (which allow you to compete directly against friends) and an improved entry dispute and review system.
I am also working on a mobile app so users can play the game more easily on the move.
If you have the time, please sign up and join in the fun!
