In the game Ultimate Tic Tac Toe you will see the playing field divided into an equal number of squares. Your task is to put a cross in one of the cells. After that, your opponent will make a move and put a nought. The one who forms a line first will win the game. Jan 06, 2020  Ultimate Tic-Tac-Toe takes the classic game of Tic-Tac-Toe and adds a strategic layer to it.

Today, in the game Ultimate Tic Tac Toe, we will play in such a world-famous game as tic-tac-toe. Now we will remind you the rules of this game.

Before you will see the playing field divided into an equal number of squares. You will play crosses. Your task is to carefully examine the playing field and put a cross in one of their cells. Then your opponent will make a move and put a zero.

Now it's your turn to make your move again. So you must build a line of three crosses. And while interfering with his opponent to do the same. The winner in the game is the one who is the first to form such a line.

What it is: A much more strategic version of tic-tac-toe I learned from Math with Bad Drawings (he’s got a great explanation of the game, too)

Best for: Two players

What you need:

• Paper
• Something to write with

How to play: OK, so we’re all familiar with tic-tac-toe, right? The normal 9-square grid?

Well, in ultimate tic-tac-toe, you’ve got a smaller grid within each of those 9 squares:

To win the game, you have to win three of the larger squares in a row, and to win a large square, you have to win three in a row in the smaller grid inside it.

Here’s how it works. Say X goes first:

Now, just like in normal tic-tac-toe, O gets to go. But O can’t just go anywhere. The smaller grid O must play in is determined by X’s move. So since X went in the bottom right corner within his small grid, O must go in the bottom right corner of the large grid:

So O goes, anywhere in this small grid he wants to:

Now you know where X has to go, right?

A few moves down, the game might look like this:

See what just happened in the far right middle square? X got three in a row! That means X wins that small grid, thus claiming that square in the large grid:

Then it’s O’s turn again (O is still sent to the small grid determined by X’s last move). Eventually someone will claim three small grids in a row, thus winning the whole game:

Nice job, X!

As you can imagine, there’s a lot of strategy involved. You’ve got to keep in mind where you’re sending your opponent, thinking several moves ahead.

One rule: If the player before you sends you to a grid that’s already been won, you get to go wherever you want. (So try not to send your opponent to an already-won grid!)

Another rule you’ll need to decide on your own will be what to do with smaller grids that result in a tie. You could either count them for 1) neither X nor O or 2) both X and O. Try both ways and let me know which one you like more!

Many thanks to Math with Bad Drawings for this fun and quite strategic game!

Variations: Aside from the normal tic-tac-toe, there’s also 3D triple-decker tic-tac-toe, and, my personal favorite, human tic-tac-toe. Who knew there were so many variations on tic-tac-toe out there?

Oh! Wait! I almost forgot! Many thanks also to my husband’s synesthesia, which helped me decide what colors to color the X and the O in the post artwork 🙂
