winnd> what means parity, like party*** lol

Sorry Dear winnd ,Parity is not a party lol

Parity:
The last player to move (normally white) has an advantage as any discs they flip in that turn can't be flipped back. This is global parity.

Strategy which consists of leaving an even number of empty squares in each region to which your opponent has access.
