The flex game is open to all users…The URL for the game is http://labs.heymath.com/Fleximagically%20Searchable/
The game is pretty straight forward. The term “Fleximagically searchable” is hidden in a set of images. The user has to find where the term is hidden within the time given. More the user plays the game, higher is the possibility of getting listed in the top 10 players.
