Tic Tac Toe ² (Ultimate)

Game Setup: • Board Structure: The game features a large 3x3 grid, with each cell containing a smaller 3x3 grid (making a total of 9 smaller grids). • Players: Two players take turns, represented as ■ and ●. Basic Gameplay: 1. First Move: ▪ The first player can place their mark (■) anywhere in any of the 81 empty cells across the entire board. 2. Subsequent Moves: ▪ The location of a player’s move determines which smaller 3x3 grid their opponent must play in next. ▪ For example, if Player 1 plays in the top-right cell of a small grid, Player 2 must then play their next move in the top-right small grid of the large board. ▪ If a move sends the opponent to a small grid that is already won or full, the opponent may choose any of the remaining cells on the entire board.
