Office workers often have three problems:

1. They sit too much
2. They drink not enough
3. They are pissed
The implemented solution covers all these issues by making the water cooler a fun place to be. Every time the users grabs some water at the water cooler she/he will get some points (tackling issue 1). Placing the water cooler at a remote area keeps the office workers walking (tackling issue 2). By implementing additional games like „squads in front of the water cooler“ the user gets the possibility to gain some extra points. This also includes games forcing the office workers to smile which not only adds some bonus points, but also forces them into a good mood (and therefore tackling issue 3).
On top of that a message can be left for the next „water cooler gamer“ (e.g. for throwing down a challenge) and therefore brings in some social factors.
Maybe there will also be a web application showing the current ranking ...
