How do I add a extra turn feature in my 3 boarded tic tac toe game? and restart option?

How do I Implement a extra turn option for example if Player X manages to get a strike in one board then next turn would still be player X's turn the same goes for player O the winner of the game would be decided on who wins the LAST board and if someone could help make a restart option it would be greatly appreciated.
