The Game Of Harmony

The game of harmony has two distinct games in Notakto and Solitaire. For solitaire, the player needs to go on selecting squares in a way that no three adjacent squares will be in a line (row/coloumn/diagonal). Choose as many squares as possible. Notakto is also the same with players needing to select squares where no three adjacent squares will be in a line (row/coloumn/diagonal). Here, the one one who selects the last square is declared the winner.
