About game

Strategic thinkers who crave a fresh twist on classic board games will find Ultimate Tic-Tac-Toe an addictive challenge. This modern take on the traditional concept forces you to master a 9x9 grid where small victories lead to the ultimate win. Every move you make dictates exactly where your opponent must play next by linking the small sub-grids together. You must carefully calculate your strategy to avoid sending your rival to a winning square while capturing your own territory. These advanced tic-tac-toe mechanics transform a simple pastime into a high-stakes battle of wits. Choose between testing your skills against a clever AI or challenging a friend in the local two-player mode. The game stands out because even a perfect opening sequence can quickly shift into a complex defensive struggle. Experience this brain-teasing puzzle right in your browser for free with no download ever required.

How to play

- A large field (9 by 9) consists of small fields (3 by 3)
- Crosses move first. They can move to any cell. On their own, they “send” the noughts to one of the small fields. For example, if the crosses went to the lower right corner of the small field, the noughts should make a move on the lower right small field, in turn, “sending” the crosses to one of the fields.
- If a move is made in such a way that it wins a small field according to the rules of ordinary tic-tac-toe, it is marked with the appropriate sign (X or O) as a victory for the player. Once a small field is won by a player or completely filled, no more moves can be made on it.
- If a player is sent to such a field, then he can make a move on any available field
- Small fields available for movement are highlighted in green
- The game ends either when the player wins a large field (by collecting 3 large X's or O's in a row) and wins the game accordingly, or when there are no possible moves left and then a draw is declared
