Hello!
It's simple.
If you are a Female, write +1 (on the previous number)
If you are a Male, write -1 (on the previous number)
The same person cannot write twice consecutively!
Wait for someone else to write
The bill can drop below 0
We all count together and may the best win
Impossible will never end i hope 
QuoteFor example
Female +1
Female +2
Male +1
Female +2
Female +3
I starting to count!!!
