Ultimate Tic-Tac-Toe Strategy: 6 Tips
The send rule turns a children's game into a real contest. These habits win it. New here? Read the rules first.
1. Look where you're sending them
Before you play a cell, look at the board it sends your opponent to. If they can win it, or win the game from it, play somewhere else.
2. Never give the free move
Sending your opponent to a finished board lets them play anywhere. That freedom is worth a lot; keep them on a leash.
3. Send them to dead boards you control
A board where you already have two in a row with the third blocked is useless to them. Sending them there costs you nothing and gives them nothing.
4. The centre board is worth the most
It's part of four lines on the big board. Fight for it, and don't send your opponent there while it's open.
5. Give up boards that don't make lines
If a small board can't complete any big-board line for your opponent, losing it costs nothing. Spend those moves on sending them somewhere harmless.
6. Count big-board threats like small ones
Two won boards in a line with the third open is a threat. Block it on the big board exactly as you would block two in a row on a small one.
Frequently asked questions
What's the most important idea?
Every move is two moves: a mark on a small board and a destination for your opponent. Beginners think about the first; the game is decided by the second.
