What it is: A more challenging and fun variation of regular tic-tac-toe.

Best for: 2 players.

What you need: Paper, something to write with, and two players.

How to play: The game is basically the same as regular tic-tac-toe: you try to win by getting three X’s or O’s in a row. The trick is, instead of one grid of nine squares, you have three grids of nine squares, all stacked on top of each other. A diagonal, horizontal, or vertical set of three lets you win, but since the game is 3-D, there are many more winning possibilities, some of which are shown here:

And it’s more fun. And challenging. And harder to end in a tie.

Variations: I suppose, since the playing space is so much larger, you could try with more than two players. I never have, but just use another letter or shape or color and see how it goes. Or I guess you could try with four grids stacked on top of each other instead of three…woah, woah, that’s a lot of squares…but who knows? 😉

  1. I love this idea! I hadn’t ever thought of it before and its such a great way to up the strategy for older students!

  2. Do you have a game of 10-12 hexangular pieces with 3 or 4 curved colors on one side. Pieces must be placed so that a cotinuous circuit is produced with all segments of the circuit being the same color.
