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:

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

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!
