Games In Office

Hi all,
we are a small IT company of 20 people.
In evening break we have some games in our office.
right now we have carom, chess and cricket in office.
we are thinking of getting one foosball table as well.
We have guitar as well. although that is not a game but helps in reducing stress.
can you suggest me some more tips to add little bit more entertainment in the office?

You can have :
Dumb Charade
JAM ( Just a minute)
Article writing on some technical issue
Skits
Quizes
Antakshari
Painting
etc

Thanks Pritha,
for your suggestions.
actually I am also thinking of starting a internal blog, where all employees can post their work.
Poems, articles, photos or other work.
Any more ideas?

Dear Mr Sarma
