Have you ever played super tic-tac-toe?

Um… maybe, when I was designing graph paper games on a daily basis back when I was 9 to 12 years old.

I definitely played 3-D Tic-Tac-Toe on the Atari 2600, but that’s different, just a 4×4 x 4 grid.

@RedDeerGuy1 Since every tic tac toe game can be forced to a draw, the same would apply to a 3×3 grid of 3×3 cells. No fun in that.

@zenvelo Yes, for the simple explanation RedDeerGuy1 listed.

The more complex version of the rules is more interesting:

Each small 3 × 3 tic-tac-toe board is referred to as a local board, and the larger 3 × 3 board is referred to as the global board.

The game starts with X playing wherever they want in any of the 81 empty spots. This move “sends” their opponent to its relative location. For example, if X played in the top right square of their local board, then O needs to play next in the local board at the top right of the global board. O can then play in any one of the nine available spots in that local board, each move sending X to a different local board.

If a move is played so that it is to win a local board by the rules of normal tic-tac-toe, then the entire local board is marked as a victory for the player in the global board.

Once a local board is won by a player or it is filled completely, no more moves may be played in that board. If a player is sent to such a board, then that player may play in any other board.

In my country we don’t have any limit to how many square we can play on. Children would just use a paper and the limit is the paper. You have to make a line of 5 to win.

I was super surprised to learn that tic-tac-toe in other countries are so limited.

I played against the computer on a Web site. I was surprised when I won one of the games. Here is a different site from the one I used.
