Tic Tac Toe Cover Up Here, it's not just about getting three X's or O's in a row. Each player has a set of pieces in different sizes. The real twist? You can cover your opponent's smaller pieces with a larger piece to claim a crucial square. This adds a whole new layer of strategy: you'll need to think not just about where to place your pieces, but also how and when to use them to dominate the board and block your opponent. It's a blend of offense, defense, and clever planning!
