Group A members will add the number of letters in their name to the previous number.
Group B members will substract the number of letters in their name from the previous number.

The team which crosses 500 or comes down to '0' is the winner..


Hope it is clear...

I will start the game with the number 80.
I am from Group A and count of letters in my name is 7 , so I add 7 to 80
80+7=87

(Next person to add/substract the number of letters in his/her name to/from 87).
