If you are over the age of five, you probably know how to play tic-tac-toe. If you are over the age of eight, chances are you’ve learned the tricks and may have already mastered it. If you are over the age of 10, well it’s hardly a challenging game at all…the biggest challenge being the player who gets to go first.
Perhaps it’s time for a real tic-tac-toe challenge.
What you need:
Just like traditional tic-tac-toe, all you need is paper and a pen or pencil. However, to more easily track each player’s moves, you may want to select a unique color for each player in addition to the traditional “X” and “O.” Start by drawing a large tic-tac-toe board, essentially filling the whole page. Within each of the nine squares, draw a little tic-tac-toe board. Or, you can print out this Tic-Tac-Toe Grid.
Each time a player wins a little board, that whole square now counts as a win for that player, either X or O, and the winner is the person who wins 3 large squares in a row. (See photos above.) It may start as simple tic-tac-toe, but it gets more difficult as you go – it’s a tic-tac-toe game that requires much attention and a bit of strategy.
What are the rules of play?
When a player fills in any square on a little tic-tac-toe board, the next player has to go to the little board in the matching part of the giant board. You are probably thinking, “Huh?” So here’s an example: If someone fills in the center box on any one of the nine mini-boards (see below, 1), the other player has to make a move on the center board of the large board (2); if he then fills in the top left square on the mini-board (located in the center of the large board), the first player must now go to the top left min-board (3). As the min-boards fill up, you must avoid sending the other player to a mini-board where he or she could win. It isn’t as confusing it sounds, but it is challenging!
