Mah Jongg -V-G-A- 

Mahjong is a high-tech simulation of the ancient Chinese game of 
MahJongg. Some historians date Mah Jongg back to the time of
Confucius -- over 25 centuries ago!The object of Mah Jongg is simple -
- remove all of the tiles by matching pairs. But there IS a catch.  
Only tiles which are "free" can be removed.
