Description: The Ultimate version of the game offers a much larger board, significantly enhancing its strategic and tactical complexity. Instead of the traditional 3x3 grid found in classic tic-tac-toe, Ultimate features a grand total of 81 cells arranged in 9 mini-boards, each measuring 3x3. This interconnected setup means that while each small board operates like a standard tic-tac-toe field, the outcomes of these mini-games influence the overall game state. As a result, players must think beyond basic intuition; they need to anticipate their opponent's moves and consider how winning on one of the smaller boards can impact the larger game. This added layer of interaction opens up a wealth of new strategic possibilities.
